    OPINION
    JUSTICE DONOHUE                                      DECIDED: June 20, 2017
    In 1971, by a margin of nearly four to one, the people of Pennsylvania ratified a
    proposed amendment to the Pennsylvania Constitution’s Declaration of Rights, formally
    and forcefully recognizing their environmental rights as commensurate with their most
    sacred political and individual rights.   Article I, Section 27 of the Pennsylvania
    Constitution provides:
    The people have a right to clean air, pure water, and to the
    preservation of the natural, scenic, historic and esthetic
    values of the environment. Pennsylvania’s public natural
    resources are the common property of all the people,
    including generations yet to come. As trustee of these
    resources, the Commonwealth shall conserve and maintain
    them for the benefit of all the people.
    Pa. Const. art. I, § 27. In this case, we examine the contours of the Environmental
    Rights Amendment in light of a declaratory judgment action brought by the
    Pennsylvania Environmental Defense Foundation (“Foundation”), an environmental
    advocacy entity, challenging, inter alia, the constitutionality of statutory enactments
    relating to funds generated from the leasing of state forest and park lands for oil and
    gas exploration and extraction. Because state parks and forests, including the oil and
    gas minerals therein, are part of the corpus of Pennsylvania’s environmental public
    trust, we hold that the Commonwealth, as trustee, must manage them according to the
    plain language of Section 27, which imposes fiduciary duties consistent with
    Pennsylvania trust law. We further find that the constitutional language controls how
    the Commonwealth may dispose of any proceeds generated from the sale of its public
    natural resources. After review, we reverse in part, and vacate and remand in part, the
    Commonwealth Court’s order granting summary relief to the Commonwealth and
    denying the Foundation’s application for summary relief.
    I. History and Enactment of the Environmental Rights Amendment
    Section 27 contains an express statement of the rights of the people and the
    obligations of the Commonwealth with respect to the conservation and maintenance of
    our public natural resources. In Robinson Township v. Commonwealth, 
    83 A.3d 901
    (Pa. 2013) (plurality), a plurality of this Court carefully reviewed the reasons why the
    Environmental Rights Amendment was necessary, the history of its enactment and
    ratification, and the mischief to be remedied and the object to be attained. At the outset
    of this opinion, we reiterate this historical background, which serves as an important
    reminder as we address the issues presented in the present case:
    [J-35-2016] - 2
    It is not a historical accident that the Pennsylvania
    Constitution now places citizens' environmental rights on par
    with their political rights. Approximately three and a half
    centuries ago, white pine, Eastern hemlock, and mixed
    hardwood forests covered about 90 percent of the
    Commonwealth's surface of over 20 million acres. Two
    centuries later, the state experienced a lumber harvesting
    industry boom that, by 1920, had left much of Pennsylvania
    barren. “Loggers moved to West Virginia and to the lake
    states, leaving behind thousands of devastated treeless
    acres,” abandoning sawmills and sounding the death knell
    for once vibrant towns. Regeneration of our forests (less the
    diversity of species) has taken decades.
    Similarly, by 1890, “game” wildlife had dwindled “as a
    result of deforestation, pollution and unregulated hunting and
    trapping.” As conservationist John M. Phillips wrote, “In
    1890, the game had practically disappeared from our state....
    We had but few game laws and those were supposed to be
    enforced by township constables, most of whom were
    politicians willing to trade with their friends the lives of our
    beasts and birds in exchange for votes.” In 1895, the
    General Assembly created the Pennsylvania Game
    Commission and, two years later, adopted a package of new
    game laws to protect endangered populations of deer, elk,
    waterfowl, and other game birds.            Over the following
    decades, the Game Commission sought to restore
    populations of wildlife, by managing and restocking species
    endangered or extinct in Pennsylvania, establishing game
    preserves in state forests, and purchasing state game lands.
    Sustained efforts of the Game Commission over more than a
    century (coupled with restoration of Pennsylvania's forests)
    returned a bounty of wildlife to the Commonwealth.
    The third environmental event of great note was the
    industrial exploitation of Pennsylvania's coalfields from the
    middle of the nineteenth well into the twentieth century.
    During that time, the coal industry and the steel industry it
    powered were the keystone of Pennsylvania's increasingly
    industrialized economy.       The two industries provided
    employment for large numbers of people and delivered
    tremendous opportunities for small and large investors.
    “[W]hen coal was a reigning monarch,” the industry operated
    “virtually unrestricted” by either the state or federal
    government. The result, in the opinion of many, was
    devastating to the natural environment of the coal-rich
    [J-35-2016] - 3
    regions of the Commonwealth, with long-lasting effects on
    human health and safety, and on the esthetic beauty of
    nature. These negative effects include banks of burning or
    non-burning soft sooty coal and refuse; underground mine
    fires; pollution of waters from acid mine drainage;
    subsidence of the soil; and landscapes scarred with strip
    mining pits and acid water impoundments. In the mid–
    1960s, the Commonwealth began a massive undertaking to
    reclaim over 250,000 acres of abandoned surface mines and
    about 2,400 miles of streams contaminated with acid mine
    drainage, which did not meet water quality standards. The
    cost of projects to date has been in the hundreds of millions
    of dollars, and the Department of Environmental Protection
    has predicted that an estimated 15 billion dollars is in fact
    necessary to resolve the problem of abandoned mine
    reclamation alone. 
    Id. The overwhelming
    tasks of reclamation and
    regeneration of the Commonwealth's natural resources,
    along with localized environmental incidents (such as the
    1948 Donora smog tragedy in which twenty persons died of
    asphyxiation and 7,000 persons were hospitalized because
    of corrosive industrial smoke; the 1959 Knox Mine disaster in
    which the Susquehanna River disappeared into the Pittston
    Coal Vein; the 1961 Glen Alden mine water discharge that
    killed more than 300,000 fish; and the Centralia mine fire
    that started in 1962, is still burning, and led to the relocation
    of all residents in 1984) has led to the gradual enactment of
    statutes protecting our environment. The drafters of the
    Environmental Rights Amendment recognized and
    acknowledged the shocks to our environment and quality of
    life:
    We seared and scarred our once green and
    pleasant land with mining operations. We
    polluted our rivers and our streams with acid
    mine drainage, with industrial waste, with
    sewage. We poisoned our ‘delicate, pleasant
    and wholesome’ air with the smoke of steel
    mills and coke ovens and with the fumes of
    millions of automobiles. We smashed our
    highways through fertile fields and thriving city
    neighborhoods. We cut down our trees and
    erected eyesores along our roads. We uglified
    our land and we called it progress.
    [J-35-2016] - 4
    1970 Pa. Legislative Journal–House at 2270 (quoting
    anonymous 1698 description of Penn's Woods air).
    With these events in the recent collective memory of
    the General Assembly, the proposed Environmental Rights
    Amendment received the unanimous assent of both
    chambers during both the 1969–1970 and 1971–1972
    legislative sessions.    Pennsylvania voters ratified the
    proposed amendment of the citizens' Declaration of Rights
    on May 18, 1971, with a margin of nearly four to one,
    receiving 1,021,342 votes in favor and 259,979 opposed.
    The decision to affirm the people's environmental
    rights in a Declaration or Bill of Rights, alongside political
    rights, is relatively rare in American constitutional law. In
    addition to Pennsylvania, Montana and Rhode Island are the
    only other states of the Union to do so. See Pa. Const. art. I,
    § 27 (1971); Mt. Const. art. II, § 3 (1889); R.I. Const. art. I, §
    17 (1970).        Three other states—Hawaii, Illinois, and
    Massachusetts—articulate and protect their citizens'
    environmental rights in separate articles of their charters.
    See Hi. Const. art. XI, §§ 1, 9 (1978); Ill. Const. art. XI, §§ 1,
    2 (1971–72); Ma. Const. amend. 49 (1972). Of these three
    states, Hawaii and Illinois, unlike Pennsylvania, expressly
    require further legislative action to vindicate the rights of the
    people. By comparison, other state charters articulate a
    “public policy” and attendant directions to the state
    legislatures to pass laws for the conservation or protection of
    either all or enumerated natural resources. See, e.g., Ak.
    Const. art. VIII, §§ 1–18 (1959); Colo. Const. art. XXVII, § 1
    (1993); La. Const. art. IX, § 1 (1974); N.M. Const. art. XX, §
    21 (1971); N.Y. Const. art. XIV, §§ 1–5 (1941); Tx. Const.
    art. XVI, § 59 (1917); Va. Const. art. XI, §§ 1–4 (1971).
    Some charters address the people's rights to fish and hunt,
    often qualified by the government's right to regulate these
    activities for the purposes of conservation. See, e.g., Ky.
    Const. § 255A (2012); Vt. Const. Ch. II, § 67 (1777); Wi.
    Const. art. I, § 26 (2003). Still other state constitutions simply
    authorize the expenditure of public money for the purposes
    of targeted conservation efforts. See, e.g., Or. Const. art. IX–
    H, §§ 1–6 (1970); W.V. Const. art. VI, §§ 55, 56 (1996).
    Finally, many of the remaining states do not address natural
    resources in their organic charters at all. See, e.g., Nv.
    Const. art. I, § 1 et seq.
    [J-35-2016] - 5
    That Pennsylvania deliberately chose a course
    different from virtually all of its sister states speaks to the
    Commonwealth's experience of having the benefit of vast
    natural resources whose virtually unrestrained exploitation,
    while initially a boon to investors, industry, and citizens, led
    to destructive and lasting consequences not only for the
    environment but also for the citizens' quality of life. Later
    generations paid and continue to pay a tribute to early
    uncontrolled and unsustainable development financially, in
    health and quality of life consequences, and with the
    relegation to history books of valuable natural and esthetic
    aspects of our environmental inheritance. The drafters and
    the citizens of the Commonwealth who ratified the
    Environmental Rights Amendment, aware of this history,
    articulated the people's rights and the government's duties to
    the people in broad and flexible terms that would permit not
    only reactive but also anticipatory protection of the
    environment for the benefit of current and future generations.
    Moreover,       public   trustee    duties    were    delegated
    concomitantly to all branches and levels of government in
    recognition that the quality of the environment is a task with
    both local and statewide implications, and to ensure that all
    government neither infringed upon the people's rights nor
    failed to act for the benefit of the people in this area crucial
    to the well-being of all Pennsylvanians.

    II. Factual and Procedural Background of the Present Case
    While the issues in this case arise from the recent leasing of Commonwealth
    forest and park lands for Marcellus Shale gas extraction, the Commonwealth has a
    history of leasing its land to private parties for oil and gas exploration dating back to
    1947. Pa. Envtl. Def. Found. v. Com., 
    108 A.3d 140
    , 143 (Pa. Cmwlth. 2015) (“PEDF”);
    see also Prelim. Inj. Hr’g Ex. R-8 at 35 (Governor’s Marcellus Shale Advisory
    Commission Report dated July 22, 2011). In 1955, the Legislature enacted the Oil and
    Gas Lease Fund Act (“Lease Fund Act”), 71 P.S. §§ 1331-1333, requiring “[a]ll rents
    and royalties from oil and gas leases” of Commonwealth land to be deposited in the “Oil
    [J-35-2016] - 6
    and Gas Lease Fund” (“Lease Fund”) to be “exclusively used for conservation,
    recreation, dams, or flood control or to match any Federal grants which may be made
    for any of the aforementioned purposes.” 71 P.S. § 1331.1 When enacted, the Lease
    Fund Act further provided the Secretary of Forests and Waters with the discretion “to
    determine the need for and the location of any project authorized.” 71 P.S. § 1332.
    Additionally, the Lease Fund Act provided that “[a]ll the moneys from time to time paid”
    1
    In its entirety, the Oil and Gas Lease Fund Act provides as follows:
    § 1331. Source and use of fund
    All rents and royalties from oil and gas leases of any land
    owned by the Commonwealth, except rents and royalties
    received from game and fish lands, shall be placed in a
    special fund to be known as the “Oil and Gas Lease Fund”
    which fund shall be exclusively used for conservation,
    recreation, dams, or flood control or to match any Federal
    grants which may be made for any of the aforementioned
    purposes.
    § 1332. Need for and location of projects; acquisition of
    lands
    It shall be within the discretion of the Secretary of Forests
    and Waters to determine the need for and the location of any
    project authorized by this act. The Secretary of Forests and
    Waters shall have the power to acquire in the name of the
    Commonwealth by purchase, condemnation or otherwise
    such lands as may be needed.
    § 1333. Appropriation
    All the moneys from time to time paid into the “Oil and Gas
    Lease Fund” are specifically appropriated to the Department
    of Forests and Waters to carry out the purposes of this act.
    71 P.S. §§ 1331-1333. As noted infra, the Department of
    Forests and Waters has been replaced by the Pennsylvania
    Department of Conservation and Natural Resources (DCNR)
    for purposes of the Lease Fund Act, see 71 P.S. §
    1340.304(c).
    [J-35-2016] - 7
    into the Fund “are specifically appropriated to the Department of Forests and Waters to
    carry out the purposes of this act.” 71 P.S. § 1333.
    In 1995, the Legislature enacted the Conservation and Natural Resources Act
    (“CNRA”), which created the Pennsylvania Department of Conservation and Natural
    Resources (“DCNR”) as a “cabinet-level advocate” for the State parks, forests, and
    other natural resources. 71 P.S. § 1340.101(b)(1). Referencing the Environmental
    Rights Amendment, Article I, Section 27, of the Pennsylvania Constitution, the CNRA
    indicates that the prior “structure of the Department of Environmental Resources
    impede[d] the Secretary of Environmental Resources from devoting enough time,
    energy and money to solving the problems facing our State parks and forests,” such
    that the state parks and forests had “taken a back seat to other environmental issues . .
    . .” 71 P.S. § 1340.101(a)(7), (8).
    The CNRA sets forth the DCNR’s primary mission as follows:
    [T]o maintain, improve and preserve State parks, to manage
    State forest lands to assure their long-term health,
    sustainability and economic use, to provide information on
    Pennsylvania’s ecological and geologic resources and to
    administer grant and technical assistance programs that will
    benefit rivers conservation, trails and greenways, local
    recreation, regional heritage conservation and environmental
    education programs across Pennsylvania.
    71 P.S. § 1340.101(b)(1). To pursue this mission, the DCNR is “empowered to make
    and execute contracts or leases in the name of the Commonwealth for the mining or
    removal of any valuable minerals that may be found in State forests” if the DCNR
    determines that it “would be for the best interests of this Commonwealth.” 71 P.S. §
    1340.302(a)(6). Moreover, the DCNR replaced the Department of Forests and Waters
    as the relevant entity for purposes of the Lease Fund.           71 P.S. § 1340.304.
    [J-35-2016] - 8
    Accordingly, the CNRA altered the Lease Fund to provide that “all moneys” paid in to
    the Lease Fund were “specifically appropriated to” the DCNR. 71 P.S. § 1333.
    In August 2008, after conducting an environmental review, 2 DCNR began its first
    foray into the Marcellus Shale natural gas play3 by approving a lease sale of 74,000
    acres (“2008 Leases”). 
    PEDF, 108 A.3d at 143-44
    . The leases generated funds in the
    form of rents and royalties.     The rents were comprised of annual rental fees, an
    example of which ranged from $20-35 per acre, in addition to large initial “bonus
    payments” ranging in the millions of dollars. 
    Id. at 144
    (citing Prelim. Inj. Hr’g Ex. R-1).
    In addition, the leases further provided for royalties when gas is extracted, with the
    payment based upon the amount of marketable gas extracted. 
    Id. The Marcellus
    Shale
    leases dramatically increased the money flowing into the Lease Fund.           Indeed, the
    cumulative proceeds from Commonwealth oil and gas leases from 1947-2008 totaled
    $165 million, where the oil and gas proceeds in 2009 alone exceeded $167 million, the
    2
    The DCNR’s findings were published and entitled, “August 2008 Oil and Gas Lease
    Sale State Forest Environmental Review.” Prelim. Inj. Hr’g Ex. R-5. The DCNR
    summarized its conclusions:
    This environmental review is based on the [Bureau of
    Forestry’s] deliberations on the scope, potential impacts and
    benefits of these deep gas plays. Based on these
    deliberations, the [DCNR] decided to pursue this opportunity
    under a portion of the State Forests where our management
    protocols will support natural gas exploration and
    development as well as satisfy our legal mandates to offer
    State Forest land for this purpose.

    The U.S. Energy Information Administration defines a “play” as “[a] set of known or
    postulated oil and gas accumulations sharing similar geologic, geographic, and
    temporal properties, such as source rock, migration pathway, timing, trapping
    mechanism, and hydrocarbon type.” U.S. Energy Information Administration Glossary,
    http://www.eia.gov/tools/glossary/index.cfm (last visited June 15, 2017).
    [J-35-2016] - 9
    bulk of which derived from the initial bonus payments (which are categorized under the
    lease terms as rental payments) from the 2008 Leases. Prelim. Inj. Hr’g Ex. R-14 at
    200-201 (“2014 Shale Gas Monitoring Report”).
    Following the 2008 Leases, the DCNR “decided not to enter into further leases
    for natural gas extraction on State lands pending study of the ‘Marcellus play’ and
    development within the 660,000 acres of land already leased within the Marcellus Shale
    region,” which included previously leased mineral rights and lands that were not owned
    by the Commonwealth.4       
    PEDF, 108 A.3d at 144
    . The former head of the DCNR
    testified that “we felt strongly that[,] until we could further develop and monitor what was
    going on[,] … we believed there should be no further gas leasing because we were
    going to be watching a tremendous amount of gas activity on the state forest for the
    next 50 years.” Prelim. Inj. Hr’g. Notes of Testimony, 5/28/2015, at 36. Notwithstanding
    this concern, the DCNR received substantial pressure, as described below, between
    2008 and 2014 from the executive and legislative branches to lease more state land as
    a means to reduce the substantial shortfalls in Pennsylvania’s general budgets.
    During the 2009-10 budget process, the Legislature added Article XVI-E to the
    Fiscal Code addressing Marcellus Shale leasing (“2009 Fiscal Code Amendments”).
    Following a definitional section, the article addresses appropriations to the Lease Fund:
    Notwithstanding any other provision of law and except as
    provided in section 1603-E [providing for an annual
    appropriation to DCNR of up to $50 million of royalties], no
    money in the [Lease Fund] from royalties may be expended
    unless appropriated or transferred to the General Fund by
    the General Assembly from the fund. In making
    4
    The acreage amounts utilized by the parties are not entirely consistent. The specific
    number of acres, however, is irrelevant to the issues before this Court.
    [J-35-2016] - 10
    appropriations, the General Assembly shall consider the
    adoption of an allocation to municipalities impacted by a
    Marcellus well.
    72 P.S. § 1602-E. This provision wrought a dramatic change in the flow of royalties
    from the Lease Fund. While Section 1333 of the Lease Fund Act previously provided for
    the automatic appropriation of “all moneys” (which would include both rents and
    royalties) paid into the Lease Fund to be appropriated to the DCNR, the newly enacted
    Section 1602-E granted the General Assembly authority over the royalties in the Lease
    Fund (other than Section 1603-E’s $50 million annual appropriation to the DCNR) by
    providing that the “royalties may not be expended unless appropriated or transferred to
    the General Fund by the General Assembly.” 
    Id. The next
    provision of the 2009 Fiscal Code Amendments, Section 1603-E,5 limits
    the DCNR’s annual allocation of royalties to an amount “up to $50 million.” While $50
    million was substantially greater that any pre-2009 royalty receipts, it was not
    guaranteed and also functions to limit the percentage of the Lease Fund royalties
    directed to the DCNR, which is particularly relevant as the DCNR had anticipated
    5
    72 P.S. § 1603-E. Department of Conservation and Natural Resources
    Subject to the availability of money in the fund following transfers, up to
    $50,000,000 from the fund from royalties shall be appropriated annually to
    the [DCNR] to carry out the purposes set forth in the act of December 15,
    1955 (P.L. 865, No. 256), entitled “An act requiring rents and royalties
    from oil and gas leases of Commonwealth land to be placed in a special
    fund to be used for conservation, recreation, dams, and flood control;
    authorizing the Secretary of Forests and Waters to determine the need for
    and location of such projects and to acquire the necessary land.” The
    [DCNR] shall give preference to the operation and maintenance of State
    parks and forests.

    receiving the full amount of the rents and royalties to allow it to oversee the rapid
    expansion of drilling on state land when it decided to enter into the 2008 Leases.
    Additionally, while the Lease Fund Act requires that the funds generated by leasing be
    “exclusively used for conservation, recreation, dams, or flood control or to match
    [related] Federal grants,” 71 P.S. § 1331, the newly-enacted Section 1603-E designates
    that preference be given instead “to the operation and maintenance of State parks and
    forests.” 72 P.S. § 1603-E.
    Section 1604-E of the 2009 Fiscal Code Amendments also required a transfer of
    $60 million in fiscal year 2009-2010 from the Lease Fund to the General Fund, which
    was not restricted to conservation purposes. 72 P.S. § 1604-E.6              Finally, the
    Supplemental General Appropriations Act of 2009 directed a transfer of $143 million
    from the Lease Fund to the General Fund. Act of Oct. 9, 2009, P.L. 779, No. 10A, §
    1912.
    Thereafter, the DCNR abandoned its self-imposed moratorium on leasing
    additional state land for Marcellus Shale development “as a direct result of certain line
    items contained within the budget agreement and fiscal code for FY 2009-10.” Prelim.
    Inj. Hr’g Ex. R-6 at 5 (unnumbered) (FY 2009-2010 Oil & Gas Lease Sale State Forest
    Environmental Review). After again conducting an environmental review, 7 the DCNR
    leased approximately 32,000 acres of state forest land in January 2010 (“January 2010

    72 P.S. § 1604-E provides, “Notwithstanding section 1603-E or any other provision of
    law, in fiscal year 2009-2010 the amount of $60,000,000 shall be transferred from the

    Leases”). Although, prior to the lease sale, the DCNR Secretary expressed significant
    concern regarding further leasing,8 the DCNR, in its published environmental review,
    concluded that “the impending [lease] sale still meets the Bureau’s management
    guidelines and protocols.” 
    Id. Again, following
    the January 2010 leases, the DCNR intended to halt any further
    leasing to allow study of the current leases and to avoid overextending its ability to
    manage them. Nevertheless, due to pressure from the Governor and pending budget
    transfers, the DCNR leased an additional 33,000 acres in May 2010 (“May 2010
    Leases”) to generate funds after conducting an environmental review. 9 A few months
    later, the General Assembly enacted an appropriation for Fiscal Year 2010-2011
    transferring $180 million from the Lease Fund to the General Fund.10
    Just before leaving office in January 2011, Governor Rendell signed an executive
    order imposing a moratorium on future leasing of state forest and park lands for oil and
    gas development, finding that further leasing would “jeopardize DCNR’s ability to fulfill
    its duty to conserve and maintain this public natural resource.” Prelim. Inj. Hr’g Ex. P-8

    mandated $180 million needed for the Commonwealth budget.”

    In 2010, 72 P.S. § 1605-E, entitled “Additional transfers” provided, “Notwithstanding
    section 1603-E or any other provision of law, in fiscal year 2010-2011, the amount of
    $180,000,000 shall be transferred from the fund to the General Fund.”
    [J-35-2016] - 13
    For the first three years of Governor Corbett’s administration, the Fiscal Code
    was not amended to provide transfers from the Lease Fund to the General Fund.
    Instead, the General Appropriations Act for 2011 and 2012 provided appropriations to
    the DCNR from both the General Fund and the Lease Fund (specifically from royalties),
    in addition to the up to $50 million in royalties provided annually by Section 1603-E of
    the 2009 Fiscal Code Amendments and the continued flow of all rental fees from oil and
    gas leases pursuant to Section 1333 of the Lease Fund Act. 
    PEDF, 108 A.3d at 148
    -
    49. The 2013 General Appropriations Act decreased the appropriation to the DCNR
    from the General Fund and increased the appropriation from the Lease Fund to the
    DCNR, resulting in a larger portion of monies from the Lease Fund being used to pay
    for the DCNR’s operational expenses, which had previously been funded by the
    General Fund, and thus reduced the amount of monies available for the DCNR’s
    conservation activities. 
    Id. at 1
    49.
    Although the first few years of the Corbett administration did not witness
    appropriations from the Lease Fund directly to the General Fund, Act 13 of 2012, which
    amended the Lease Fund Act, required other transfers from the Lease Fund.
    Specifically, Act 13 created the Marcellus Legacy Fund, which was funded in part by
    fees on unconventional wells but also by annual appropriations from the Lease Fund in
    increasing amounts beginning with $20 million in 2013 and rising to $50 million for all
    years after 2015.    58 Pa.C.S. §§ 2315(a.1), 2505.11     The monies in the Marcellus

    Legacy Fund are earmarked for the Environmental Stewardship Fund and the
    Hazardous Sites Cleanup Fund, providing capital for projects not controlled by the
    DCNR. 
    Id. In May
    2014, Governor Corbett modified the moratorium banning the leasing of
    State lands and instead forbade any leasing that “would result in additional surface
    disturbances on state forest or state park lands.” Prelim. Inj. Hr’g Ex. P-8 at 3. The
    order further provided that the royalties from the additional leasing would be used to
    repair the infrastructure of the forest and park lands, to acquire lands of “high
    conservation value or ecological importance,” and to acquire private oil, gas, and
    mineral rights currently owned by private parties under state surface lands. 
    Id. The 2014-2015
       General    Appropriations    Act   again   included   increased
    appropriations of royalties from the Lease Fund to the DCNR that were mirrored by
    decreased appropriations from the General Fund to the DCNR. 
    PEDF, 108 A.3d at 151
    .
    In 2014, the Fiscal Code was amended again to address Marcellus Shale leasing
    (“2014 Fiscal Code Amendments”). Specifically, Section 1605-E of the Fiscal Code was
    amended to provide for an appropriation of $95 million from the Lease Fund to the
    General Fund. 72 P.S. § 1605-E(b).12
    The 2014 Fiscal Code Amendments also added specific legislative findings in
    support of the increased leasing of state land and the transfers of capital from the Lease
    Fund. These findings postulate that Marcellus Shale leasing “is necessary to obtain the
    12
    Section 1605-E(b) provides, “Notwithstanding section 1603-E or any other provision
    of law, in fiscal year 2014-2015, the amount of $95,000,000 shall be transferred from
    the fund to the General Fund.” 72 P.S. § 1605-E. As with Sections 1604-E and 1605-
    E(a), Section 1605-E(b) does not indicate on its face whether it relates to royalties,
    rents, or bonus bid payments, or some combination of the three.
    [J-35-2016] - 15
    revenue necessary to effectuate the . . . General Appropriations Act of 2014.” 72 P.S.
    § 1601.1-E (1). Additionally, the findings state that “[t]he fund is not a constitutional
    trust.” 72 P.S. § 1601.1-E (6). After recognizing that the increase in the Fund was due
    to   the    Marcellus   Shale   development,    the   Legislature   indicates    that   “[t]he
    Commonwealth’s role as trustee of the public’s natural resources is broader and more
    comprehensive than just conserving the State forest and parks.” 72 P.S. § 1601.1-E
    (7), (8).    It further affirmatively instructs that “it is in the best interest of the
    Commonwealth to lease oil and gas rights in State forests and parks” if the DCNR
    employs lease protections and best management practices and “maintains a balance of
    money in the [Lease Fund] to carry out [DCNR’s] obligation to protect State forest and
    park land and other environmental activities.” 72 P.S. § 1601.1-E (9)(iii). Finally, the
    statute provides that transfers from the Fund to the General Fund are permissible if the
    balance of money in the Fund is “adequate to achieve the purposes” of paragraph nine,
    72 P.S. § 1601.1-E (10), which directs the DCNR to make state forest and park land
    leasing decisions based on all the Commonwealth’s interests.13 72 P.S. § 1601.1-E (9).
    13
    72 P.S. § 1601.1-E, entitled “Legislative Findings” includes the following as
    paragraph 9:
    The General Assembly affirms its intent that:
    (i) The [DCNR] should continue the operation of the shale
    gas monitoring activities program to monitor, evaluate and
    report the impacts of shale gas activities in State forest and,
    in consultation with the Governor’s Office, utilize data
    received from ongoing monitoring to adjust its management
    planning and practices.
    (ii) The [DCNR] should consider the State forest and park
    lands as one of the Commonwealth’s interests when
    considering whether or not to lease additional State forest

    [J-35-2016] - 16
    Distinguished Professor John C. Dernbach of the Widener University Law School
    Environmental Law and Sustainability Center14 recently summarized the significance of
    Fiscal Code amendments for purposes of the claims at bar:
    Three legislative amendments to the state fiscal code
    between 2008 and 2014 redirected a total of $335 million
    that would have been used for conservation purposes under
    the [Lease Fund Act] to the general fund, where it is
    appropriated for a variety of state government purposes. In
    addition, the Legislature prevented DCNR from spending
    any [Lease Fund Act] royalties without prior legislative
    authorization. Finally, the Legislature began using [Lease
    Fund] revenue to support the overall budget of DCNR, rather
    than obtaining that budget money from the general fund and
    using [Lease Fund] money for conservation purposes related
    to oil and gas extraction
    John C. Dernbach, The Potential Meanings of a Constitutional Public Trust, 45 Envtl. L.
    463, 488 (2015) (footnotes omitted)).
    (…continued)
    and park lands and determining what is in the best interests
    of the Commonwealth. Interest involved in decisions relating
    to leasing State forest and park lands should not be made to
    the exclusion of all other interests of the Commonwealth.
    (iii) Notwithstanding any other law to the contrary, it is in the
    best interest of the Commonwealth to lease oil and gas
    rights in State forests and parks if the [DCNR]:
    (A) in consultation with the Governor, continues strong and
    effective lease protections, best management practices and
    ongoing monitoring programs on the impact of gas
    operations; and
    (B) maintains a balance of money in the fund to carry out the
    [DCNR’s] statutory obligation to protect State forest and park
    land and other environmental activities.
    14
    Writing in support of neither party, Professor Dernbach filed a scholarly amicus brief
    in the case at bar.
    [J-35-2016] - 17
    Acknowledging the structural changes in the source of the funding, the
    Commonwealth nevertheless emphasizes that the total annual appropriations to the
    DCNR from the various sources ranged between $69 million in 2012-2013 to $122
    million in 2014-2015 and further observes that the DCNR received approximately fifty
    percent of the over $926 million in total oil and gas lease revenues accumulated from
    Fiscal     Year   2008-2009     through    Fiscal    Year       2014-2015     (then-projected).

    III. Commonwealth Court Proceedings
    Appellant, the Foundation, brought a claim in the Commonwealth Court under the
    fiduciary provisions of the Declaratory Judgment Act against the Commonwealth of
    Pennsylvania      and   the   Governor,   in   his   official   capacity    (collectively,   “the
    Commonwealth”) regarding the 2009-2015 budget related decisions that resulted in the
    additional lease sales.15 The Foundation contends that these decisions violated the
    15
    The Declaratory Judgment Act provides in relevant part:
    § 7535. Rights of fiduciaries and other persons
    Any person interested, as or through an executor,
    administrator, trustee, guardian, or other fiduciary, creditor,
    devisee, legatee, heir, next of kin, or cestui que trust, in the
    administration of a trust . . . may have a declaration of rights
    or legal relations in respect thereto:
    ****
    (2) To direct the executors, administrators, or trustees to do
    or abstain from doing any particular act in their fiduciary
    capacity.

    rights of all Commonwealth citizens conferred by the Environmental Rights Amendment,
    the CNRA, and the Lease Fund Act. 
    PEDF, 108 A.3d at 154
    . The Foundation filed the
    initial action in March 2012 and amended the action with regard to subsequent
    legislation. The case at bar addresses cross-applications for summary relief, which
    allow a court to grant relief only if a party’s “right to judgment is clear and no material
    issues of fact are in dispute.” Jubelirer v. Rendell, 
    953 A.2d 514
    , 521 (Pa. 2008)
    (citations omitted).16
    The Commonwealth Court observed that the Foundation filed a brief in excess of
    100 pages raising over twenty issues focused primarily on Section 27’s protection of the
    Commonwealth’s natural resources. The court found that some of the issues were
    inappropriate for decision under the Declaratory Judgment Act (such as issues relating
    to budget proposals rather than enactments) and dismissed others for failure to join the
    lessees of the leases, whom the court deemed indispensable parties.17
    The court narrowed the remaining issues before it to three questions:
    (1) Whether Sections 1602–E and 1603–E of the Fiscal
    Code, which respectively provide that the General Assembly
    shall appropriate all royalty monies [of] the Lease Fund and
    (…continued)
    42 Pa.C.S. § 7535.
    16
    Shortly after the Commonwealth Court issued its decision, and while the lawsuit was
    pending, Governor Wolf imposed a moratorium on additional leases of state forest and
    park land, effective January 29, 2015. See Exec. Order: 2015-03 – Leasing of State
    Forest and State Park Land for Oil and Gas Development, available at
    https://www.governor.pa.gov/executive_orders/executive-order-2015-03-leasing-of-
    state-forest-and-state-park-land-for-oil-and-gas-development/.
    17
    The Commonwealth Court denied the Commonwealth’s request for a declaration
    regarding the Governor’s authority to override decisions of the DCNR in regard to oil
    and gas leasing. 
    PEDF, 108 A.3d at 173
    .
    [J-35-2016] - 19
    that, subject to availability, up to $50 million of the Lease
    Fund royalties shall be appropriated to [the] DCNR, violate
    Article I, § 27;
    (2) Whether the General Assembly’s transfers/appropriations
    from the Lease Fund violate Article I, § 27; and
    (3) Who within the Commonwealth has the duty and thus
    bears the responsibility to make determinations with respect
    to the leasing of State lands for oil and natural gas
    extraction.
    
    PEDF, 108 A.3d at 155
    .
    The Commonwealth Court recognized that the Foundation’s challenges to some
    extent overlapped with legislative policy decisions resulting from the need to balance
    the state budget. While observing that the review of legislative appropriation decisions is
    generally outside the authority of the courts, the court opined that the propriety of the
    use of special fund money, such as money from the Lease Fund, is a legal question
    subject to judicial review. It further concluded that “a decision to lease Commonwealth
    property protected by the Constitution and held in trust for the benefit of all current and
    future Pennsylvanians is an appropriate subject of judicial scrutiny.” 
    Id. Initially, the
    Commonwealth Court recognized that this Court recently addressed
    Section 27 in Robinson Township.          The court properly observed that Robinson
    Township was a plurality decision in which former-Chief Justice Castille, joined by
    Justice Todd and former-Justice McCaffery, wrote expansively on Section 27. Justice
    Baer concurred on a wholly different ground, while Chief Justice Saylor and former-
    Justice Eakin wrote in dissent. The Commonwealth Court noted that none of the
    responsive opinions adopted the plurality’s view of Section 27. Thus, the
    Commonwealth Court found “the plurality’s construction of Section 27 persuasive only
    [J-35-2016] - 20
    to the extent it is consistent with binding precedent from [the Commonwealth Court] and
    the Supreme Court on the same subject.” 
    PEDF, 108 A.3d at 156
    n.37.
    The Commonwealth Court, therefore, determined that its prior decision in Payne
    v. Kassab, 
    312 A.2d 86
    (Pa. Commw. 1973) (Payne I), controlled the questions
    presented in the case at bar, even though the plurality in Robinson Township criticized
    the test announced in Payne I as “lack[ing] foundation” in Section 27. 
    PEDF, 108 A.3d at 159
    (citing Robinson Twp., 
    83 A.3d 966-67
    ). The Commonwealth Court in Payne I
    set forth a three-part test to determine whether a use of Commonwealth land violated
    Section 27:
    (1) Was there compliance with all applicable statutes and
    regulations relevant to the protection of the Commonwealth’s
    public natural resources?
    (2) Does the record demonstrate a reasonable effort to
    reduce the environmental incursion to a minimum?
    (3) Does the environmental harm which will result from the
    challenged decision or action so clearly outweigh the
    benefits to be derived therefrom that to proceed further
    would be an abuse of discretion?
    
    Id. at 1
    58 (quoting Payne 
    I, 312 A.2d at 94
    ).
    Notably, this Court affirmed the judgment in Payne I without adopting the three-
    part test, instead concluding that the “elaborate safeguards” of the challenged statute
    provided adequate protection such that breach of the trust created by Section 27 would
    not occur. Payne v. Kassab, 
    361 A.2d 263
    , 273 (Pa. 1976) (Payne II).
    A.      Constitutionality of Sections 1602–E and 1603–E of the Fiscal Code
    under Article I, Section 27
    The Commonwealth Court first addressed the Foundation’s challenge that
    Sections 1602-E and 1603-E of the 2009 Fiscal Code Amendments violated Section 27.
    [J-35-2016] - 21
    As noted, these provisions altered the status quo which had previously appropriated to
    the DCNR all monies in the Lease Fund under the Lease Fund Act, 71 P.S. § 1333.
    The change, the Foundation argued, violated Section 27 because it (1) took away
    DCNR’s ability to use the revenues to mitigate the damage from oil and gas exploration,
    (2) removed DCNR’s ability to act as trustee because the funds were placed in the
    General Fund, potentially for non-conservation purposes, and (3) eliminated revenues
    that would otherwise have built the corpus of the Lease Fund to protect Pennsylvania’s
    natural resources. 
    PEDF, 108 A.3d at 160
    .
    Looking first to the plain language of Section 1602-E, the Commonwealth Court
    observed that the section merely transferred control over the royalties (but not the rents)
    from oil and gas leases from the DCNR to the General Assembly, which, as part of the
    Commonwealth, was also bound to safeguard the Commonwealth’s natural resources
    under Article I, Section 27. Additionally, the court recognized that Section 1602-E did
    not change the DCNR’s decision making authority regarding the granting of leases. The
    court held that the provision “does not by itself infringe upon the rights afforded the
    people” and does not “reflect a failure by the General Assembly to act consistent with its
    trustee obligations under Article I, Section 27.” 
    Id. at 1
    61. It further highlighted that the
    Lease Fund is not a constitutional creation but rather is a special fund created by
    legislative enactment, which could be altered by subsequent legislative action. 
    Id. at 1
    60. Accordingly, the court concluded that the Foundation failed to demonstrate that
    Section 1602-E “clearly, plainly, and palpably” violated Section 27. 
    Id. at 1
    61.
    Turning to Section 1603-E of the 2009 Fiscal Code Amendments, which
    transferred up to $50 million of royalties annually from the Lease Fund to the DCNR, the
    [J-35-2016] - 22
    Commonwealth Court acknowledged the Foundation’s argument that the transfer of the
    $50 million acted to limit the funding of the DCNR, as it had previously received all
    royalties from the Lease Fund. The court redefined this challenge as a claim that the
    transfer did not provide adequate funding for DCNR to protect the Commonwealth’s
    natural resources, as opposed to addressing the Foundation’s broader argument that
    the Commonwealth, specifically Governor Rendell, failed to abide by his various duties
    as trustee by limiting the funding of the DCNR. 
    Id. The Commonwealth
    Court reviewed case law addressing constitutional
    challenges based on inadequate funding of a part of government. 
    PEDF, 108 A.3d at 161-66
    . The Commonwealth Court observed that while this Court has been willing to
    act to protect the “independence of the judicial branch,” the Commonwealth Court has
    not been willing to intervene in regard to the Legislature’s authority to determine the
    funding of Commonwealth agencies.          
    Id. at 1
    61-64 (citing, inter alia, County of
    Allegheny v. Commonwealth, 
    534 A.2d 760
    (Pa. 1987) (holding legislative acts requiring
    counties to fund the local court system to be unconstitutional) and Commonwealth ex
    rel. Carroll v. Tate, 
    274 A.2d 193
    (Pa. 1971) (addressing court funding in Philadelphia)),
    164-66 (citing, inter alia, Mental Health Association in Pennsylvania v. Corbett, 
    54 A.3d 100
    (Pa. Cmwlth. 2012) (dismissing challenge based on inadequacy of funding for
    Department of Public Welfare’s mental health and intellectual disability services)).
    Reiterating its reluctance to “second guess” the amounts appropriated by the
    General Assembly to Commonwealth agencies, the Commonwealth Court applied what
    it viewed as this Court’s requirement that a challenger demonstrate that “the amount
    funded is so inadequate that it impairs the proper functioning” of the DCNR. 
    Id. at 1
    66.
    [J-35-2016] - 23
    It concluded that the Foundation “presented no evidence that the current funding
    appropriated to the DCNR from all sources is inadequate – i.e., that the funding is so
    deficient that the DCNR cannot conserve and maintain our State natural resources.” 
    Id. Accordingly, the
    court granted the Commonwealth’s motion for summary relief,
    concluding that the Foundation failed to demonstrate that Sections 1602-E and 1603-E
    violate the Constitution.
    B.     Constitutionality of Section 1604-E, Section 1605-E, and other
    transfers of money from the Lease Fund
    In regard to Sections 1604-E and 1605-E and the other budgetary transfers, see
    supra at 12-15, the Foundation argued that the money generated by oil and gas
    exploration “must be committed to furthering the purposes, rights, and protections
    afforded” under Section 27, rather than being intermingled with the General Fund. 
    Id. at 1
    67. Considering the constitutional language, the Commonwealth Court held that
    Section 27 “does not expressly command that all revenues derived from the sale or
    leasing of the Commonwealth’s natural resources must be funneled to those purposes
    and those purposes only.” 
    Id. at 1
    68.
    The court reiterated that the Lease Fund was merely a statutory special fund,
    rather than a trust fund, and opined that there was “no constitutional mandate that
    monies derived from the leasing of State lands for oil and natural gas development be
    reinvested into the conservation and maintenance of the Commonwealth’s public
    natural resources.” 
    Id. at 1
    69. Accordingly, the Commonwealth Court again held that
    the Foundation failed to demonstrate that the Fiscal Code Amendments, General
    Appropriations Act transfers, and Act 13 transfers from the Lease Fund to the General
    Fund violate the Environmental Rights Amendment, because funds appeared to be
    [J-35-2016] - 24
    used for the general “benefit of all the people.”       
    Id. The court,
    therefore, denied
    summary relief to the Foundation, granting in substantial part the Commonwealth’s
    cross-motion for summary relief.18
    IV. Analysis
    The Foundation filed a direct appeal as of right from the final order of the
    Commonwealth Court, pursuant to 42 Pa.C.S. § 723(a), raising ten issues. We
    entertained oral argument to examine the following two overarching issues:
    1. The proper standards for judicial review of government
    actions and legislation challenged under the Environmental
    Rights Amendment, Article I, Section 27 of the Pennsylvania
    Constitution, in light of Robinson Township v.
    Commonwealth, 
    83 A.3d 901
    (Pa. 2013) (plurality);
    18
    Sections 1602-E and 1603-E affect the appropriation of royalties to the DCNR,
    initially re-appropriating all such payments to the General Assembly, before authorizing
    a transfer of some royalty money back to the DCNR. The Commonwealth Court
    indicated that Sections 1604-E and 1605-E resulted in the transfer of “bonus payment
    revenue” (an elevated “first annual rental payment”) from the Lease Fund to the General
    Fund, after forcing DCNR to generate the same through additional leasing. See 
    PEDF, 108 A.3d at 146-48
    ; accord Foundation’s Brief at 76. According to the Foundation, the
    General Appropriation Act of 2009 also resulted in the transfer of bonus bid payments to
    the General Fund. See Foundation’s Brief at 76.
    The Commonwealth Court additionally considered, in regard to the Commonwealth’s
    cross-motion for summary relief, whether the Governor or only the DCNR has authority
    to enter natural gas leases. The court noted that the CNRA provides the DCNR with
    exclusive authority “to make and execute contracts or leases in the name of the
    Commonwealth for the extraction of oil and natural gas on State lands and to determine
    whether doing so is in the best interest of the Commonwealth.” 
    Id. at 1
    71 (citing 71 P.S.
    § 1340.302(a)(6)). It, therefore, denied the Commonwealth relief on this point,
    concluding that the ultimate decision lay with the DCNR, although recognizing that the
    General Assembly and the Governor could attempt to influence it. 
    Id. at 1
    72. Judge
    Cohn Jubelirer joined the majority opinion with the exception of the section addressing
    whether the Governor or the DCNR had decision-making authority in regard to future
    leases, which she deemed advisory, because no future leasing decisions had as of then
    been made.

    1602-E and 1603-E of the Fiscal Code and the General
    Assembly’s transfers/appropriations from the Lease Fund.
    Given that we are reviewing the Commonwealth Court’s decision on cross-
    motions for summary relief pursuant to Pa.R.A.P. 1532(b),19 we may grant relief only if
    no material questions of fact exist and the right to relief is clear. See 
    Jubelirer, 953 A.2d at 521
    .   Additionally, as challenges to the constitutionality of statutes present pure
    questions of law, our standard of review is de novo, and our scope of review is plenary.
    See Robinson 
    Twp., 83 A.3d at 943
    . As with any constitutional challenge to legislation,
    the challenger bears the heavy burden of demonstrating that the statute “clearly, plainly,
    and palpably violates the Constitution,” as we presume that our sister branches act in
    conformity with the Constitution. Stilp v. Commonwealth, 
    905 A.2d 918
    , 939 (Pa. 2006).
    In interpreting constitutional language, “the fundamental rule of construction which
    guides [this Court] is that the Constitution’s language controls and must be interpreted
    in its popular sense, as understood by the people when they voted on its adoption.”
    Ieropoli v. AC&S Corp., 
    842 A.2d 919
    , 925 (Pa. 2004). As with our interpretation of
    statutes, if the language of a constitutional provision is unclear, we may be informed by
    “the occasion and necessity for the provision; the circumstances under which the
    amendment was ratified; the mischief to be remedied; the object to be attained; and the
    contemporaneous legislative history.” Robinson

    A. Proper Standard of Judicial Review
    The parties, various amici, and the plurality in Robinson Township all reject the
    three-part test developed by the Commonwealth Court in Payne I as the appropriate
    standard for examining Section 27 challenges. The Commonwealth observes that the
    Payne I test has been criticized as “ill-fitted” to the language of Section 27 and as
    frustrating the development of a “coherent environmental rights jurisprudence.”
    Commonwealth’s Brief at 25 (citing Robinson 
    Township, 83 A.3d at 964
    ). Similarly, the
    Foundation urges “the issues in this case do not fit the mold of the Payne test crafted by
    the Commonwealth Court.” Foundation’s Reply Brief at 5 (discussing the Robinson
    Township plurality’s three part criticism of the Payne test).20
    We agree. The Payne I test, which is unrelated to the text of Section 27 and the
    trust principles animating it, strips the constitutional provision of its meaning. See
    Robinson 
    Twp., 83 A.3d at 967
    ; see also Dernbach, The Potential Meanings of a
    Constitutional Public Trust, 45 Envtl. L. 463, 499 (2015). Accordingly, we reject the test
    20
    In Robinson Township, the plurality explained the significant drawbacks of the
    Commonwealth Court’s Payne test:
    [T]he test poses difficulties both obvious and critical. First,
    the Payne test describes the Commonwealth's obligations—
    both as trustee and under the first clause of Section 27—in
    much narrower terms than the constitutional provision.
    Second, the test assumes that the availability of judicial relief
    premised upon Section 27 is contingent upon and
    constrained by legislative action. And, finally, the
    Commonwealth Court's Payne decision and its progeny have
    the effect of minimizing the constitutional duties of executive
    agencies and the judicial branch, and circumscribing the
    abilities of these entities to carry out their constitutional
    duties independent of legislative control.
    Robinson 
    Twp., 83 A.3d at 967
    .
    [J-35-2016] - 27
    developed by the Commonwealth Court as the appropriate standard for deciding Article
    I, Section 27 challenges.
    Instead, when reviewing challenges to the constitutionality of Commonwealth
    actions under Section 27, the proper standard of judicial review lies in the text of Article
    I, Section 27 itself as well as the underlying principles of Pennsylvania trust law in effect
    at the time of its enactment. We must therefore carefully examine the contours of the
    Environmental Rights Amendment to identify the rights of the people and the obligations
    of the Commonwealth guaranteed thereunder.
    B. The Contours of Section 27
    This is not the first time we have been called upon to address the rights and
    obligations set forth in the Environmental Rights Amendment. We did so in Robinson
    Twp., and we rely here upon the statement of basic principles thoughtfully developed in
    that plurality opinion.21 To start, the General Assembly derives its power from Article III
    of the Pennsylvania Constitution which grants broad and flexible police powers to enact
    laws for the purposes of promoting public health, safety, morals, and the general
    welfare. 
    Id. at 946.
    These powers, however, are expressly limited by fundamental
    rights reserved to the people in Article I of our Constitution. 
    Id. at 946.
    Specifically,
    Section 1 affirms, among other things, that all citizens “have certain inherent and
    indefeasible rights.” 
    Id. at 948
    (quoting Pa. Const. art. I, § 1). As forcefully pronounced
    21
    In Robinson Township, this Court considered the constitutionality of portions of Act
    13 of 2012, which amended the Pennsylvania Lease Fund Act with substantial benefits
    to the natural gas industry in response to the Marcellus Shale boom. Notably, some of
    the Foundation’s challenges in the case at bar were triggered by separate provisions of
    Act 13, specifically those provisions that created the Marcellus Legacy Fund. See 58
    Pa.C.S. §§ 2315(a.1), 2505.
    [J-35-2016] - 28
    in Section 25, the rights contained in Article I are “excepted out of the general powers of
    government and shall forever remain inviolate.” 
    Id. (quoting Pa.
    Const. art. I, § 25).
    Among the “inherent and indefeasible” rights in Article I of the Pennsylvania
    Constitution are the rights set forth in the Environmental Rights Amendment, which we
    quote again for ease of discussion:
    The people have a right to clean air, pure water, and to the
    preservation of the natural, scenic, historic and esthetic
    values of the environment. Pennsylvania's public natural
    resources are the common property of all the people,
    including generations yet to come. As trustee of these
    resources, the Commonwealth shall conserve and maintain
    them for the benefit of all the people.
    Pa. Const. art. I, § 27. This constitutional provision grants two separate rights to the
    people of this Commonwealth. The first right is contained in the first sentence, which is
    a prohibitory clause declaring the right of citizens to clean air and pure water, and to the
    preservation of natural, scenic, historic and esthetic values of the environment.
    Robinson 
    Twp., 83 A.3d at 951
    . This clause places a limitation on the state's power to
    act contrary to this right, and while the subject of this right may be amenable to
    regulation, any laws that unreasonably impair the right are unconstitutional. 
    Id. The second
    right reserved by Section 27, set forth in its second sentence, is the
    common ownership by the people, including future generations, of Pennsylvania's public
    natural resources. 
    Id. at 954.
    The “public natural resources” referenced in this second
    sentence include the state forest and park lands leased for oil and gas exploration and,
    of particular relevance in this case, the oil and gas themselves. 
    Id. at 955;
    see also Pa.
    L. Journal, 154th General Assembly, No. 118, Reg. Sess., 2271–75 (1970).                 In a
    statement offered to the General Assembly in connection with the proposed
    [J-35-2016] - 29
    Environmental Rights Amendment, Professor Robert Broughton explained that the
    provision was initially drafted as “Pennsylvania’s natural resources, including the air,
    waters, fish, wildlife, and the public lands and property of the Commonwealth ….” but
    was revised to remove the enumerated list and thereby discourage courts from limiting
    the scope of natural resources covered. Pa. L. Journal, 154th General Assembly, No.
    118, Reg. Sess., 2274 (1970) (Broughton Analysis).22
    The third clause of Section 27 establishes a public trust, pursuant to which the
    natural resources are the corpus of the trust, the Commonwealth23 is the trustee, and
    the people are the named beneficiaries. Robinson 
    Twp., 83 A.3d at 955-56
    . The terms
    “trust” and “trustee” carry their legal implications under Pennsylvania law at the time the
    amendment was adopted.         See Appeal of Ryder, 
    74 A.2d 123
    , 124 (Pa. 1950)
    (providing that “words having a precise and well-settled legal meaning must be
    22
    The sentence was also amended to include the term “public” to indicate that it did not
    apply to purely private property rights. However, Representative Kury opined that the
    trust nevertheless applied to “resources owned by the Commonwealth and also to those
    resources not owned by the Commonwealth, which involve a public interest.” Pa. L.
    Journal, 154th General Assembly, No. 118, Reg. Sess., 2271-72 (1970) (statement by
    Rep. Kury).
    23
    Trustee obligations are not vested exclusively in any single branch of Pennsylvania’s
    government, and instead all agencies and entities of the Commonwealth government,
    both statewide and local, have a fiduciary duty to act toward the corpus with prudence,
    loyalty, and impartiality. See Robinson 
    Twp., 83 A.3d at 956-57
    ; see also Pa. L.
    Journal, 154th General Assembly, No. 118, Reg. Sess., 2269, 2271 (1970).
    Importantly, in addition to its trustee obligations, the DCNR also has a statutory
    responsibility “to maintain, improve and preserve State parks, to manage State forest
    lands to assure their long-term health, sustainability and economic use.” See 71 P.S.
    § 1340.101. To pursue this mission, the DCNR is empowered with exclusive authority
    “to make and execute contracts or leases in the name of the Commonwealth for the
    mining or removal of any valuable minerals that may be found in State forests” when,
    and only when, the DCNR determines that doing so is in the best interests of the
    Commonwealth. 71 P.S. § 1340.302(a)(6).

    interpreted” accordingly); see also Robinson 
    Twp., 83 A.3d at 956
    (citing Pa.C.S. §
    1903).    Notably, Professor Broughton explained that the Commonwealth’s role was
    plainly intended to be that of a “trustee,” as opposed to “proprietor.” See Pa. L. Journal,
    154th General Assembly, No. 118, Reg. Sess., 2269, 2273 (1970) (Broughton
    Analysis). As a trustee, the Commonwealth must deal “with its citizens as a fiduciary,
    measuring its successes by the benefits it bestows upon all its citizens in their utilization
    of natural resources under law.” 
    Id. Under Section
    27, the Commonwealth may not act
    as a mere proprietor, pursuant to which it “deals at arms['] length with its citizens,
    measuring its gains by the balance sheet profits and appreciation it realizes from its
    resources operations.” 
    Id. The Robinson
    Township plurality aptly described the Commonwealth’s duties as
    the trustee of the environmental trust created by the people of Pennsylvania as follows:
    As trustee, the Commonwealth is a fiduciary obligated to
    comply with the terms of the trust and with standards
    governing a fiduciary's conduct. The explicit terms of the
    trust require the government to “conserve and maintain” the
    corpus of the trust. See Pa. Const. art. I, § 27. The plain
    meaning of the terms conserve and maintain implicates a
    duty to prevent and remedy the degradation, diminution, or
    depletion of our public natural resources. As a fiduciary, the
    Commonwealth has a duty to act toward the corpus of the
    trust—the public natural resources—with prudence, loyalty,
    and impartiality.
    Robinson 
    Twp., 83 A.3d at 956-57
    .
    Under Pennsylvania trust law, the duty of prudence requires a trustee to
    “exercise such care and skill as a man of ordinary prudence would exercise in dealing
    with his own property.” In re Mendenhall, 
    398 A.2d 951
    , 953 (Pa. 1979) (quoting
    [J-35-2016] - 31
    Restatement (Second) of Trusts § 174).24 The duty of loyalty imposes an obligation to
    manage the corpus of the trust so as to accomplish the trust’s purposes for the benefit
    of the trust’s beneficiaries. See Metzger v. Lehigh Valley Trust & Safe Deposit Co., 
    69 A. 1037
    , 1038 (Pa. 1908); see also In re Hartje's Estate, 
    28 A.2d 908
    , 910 (Pa. 1942)
    (citing Restatement (Second) of Trusts § 186 for the proposition that “the trustee can
    properly exercise such powers and only such powers as (a) are conferred upon him in
    specific words by the terms of the trust, or (b) are necessary or appropriate to carry out
    the purposes of the trust and are not forbidden by the terms of the trust”). The duty of
    impartiality requires the trustee to manage the trust so as to give all of the beneficiaries
    due regard for their respective interests in light of the purposes of the trust. 20 Pa.C.S.
    § 7773; Estate of Sewell, 
    409 A.2d 401
    , 402 (Pa. 1979) (citing Restatement (Second) of
    Trusts § 183).25
    Pennsylvania’s environmental trust thus imposes two basic duties on the
    Commonwealth as the trustee. First, the Commonwealth has a duty to prohibit the
    degradation, diminution, and depletion of our public natural resources, whether these
    harms might result from direct state action or from the actions of private parties.
    Robinson 
    Twp., 83 A.3d at 957
    . Second, the Commonwealth must act affirmatively via
    24
    The Uniform Trust Act confirms that the duty to administer with prudence involves
    “considering the purposes, provisions, distributional requirements and other
    circumstances of the trust and … exercising reasonable care, skill and caution.”
    20 Pa.C.S. § 7774. In furtherance of this duty, the trustee “shall keep adequate records
    of the administration of the trust” and “shall keep trust property separate from the
    trustee's own property.” 20 Pa.C.S. § 7780.

    Justice Baer’s contention that our holding today “cordons off” hundreds of millions of
    dollars from other budgetary uses is inaccurate. See Concurring and Dissenting

    parties and thus not presently before us.

    Id. at 958
    (citing Geer v. Connecticut,
    
    161 U.S. 519
    , 534 (1896) (trusteeship for the benefit of state's people implies legislative
    duty “to enact such laws as will best preserve the subject of the trust, and secure its
    beneficial use in the future to the people of the state”)).         Although a trustee is
    empowered to exercise discretion with respect to the proper treatment of the corpus of
    the trust, that discretion is limited by the purpose of the trust and the trustee's fiduciary
    duties, and does not equate “to mere subjective judgment.” 
    Id. at 978
    (citing Struthers
    Coal & Coke Co. v. Union Trust Co., 
    75 A. 986
    , 988 (Pa. 1910); In re Sparks' Estate,
    
    196 A. 48
    , 57 (Pa. Super. 1938)). The trustee may use the assets of the trust “only for
    purposes authorized by the trust or necessary for the preservation of the trust; other
    uses are beyond the scope of the discretion conferred, even where the trustee claims to
    be acting solely to advance other discrete interests of the beneficiaries.” 
    Id. (citing Metzger,
    69 A. at 1038); see also Hartje's 
    Estate, 28 A.2d at 910
    (“giving of [an]
    unrestricted bond” was “neither ‘necessary’ nor ‘appropriate’ to the carrying out of the
    purposes of the trust; hence, the existence of [trustee’s] power to do so by inference
    must be denied”).
    The Commonwealth argues that the revenue obtained from the disposition of
    trust assets need not be returned to the corpus of the trust or otherwise dedicated to
    trust purposes, for two reasons.         First, the Commonwealth contends that the
    Environmental Rights Amendment is “silent” as to the use of proceeds from the sale of
    natural resources, and “addresses neither the appropriations process nor funding for
    conservation purposes.” See Commonwealth’s Brief at 39. This is plainly inaccurate,
    as Section 27 expressly creates a trust, and pursuant to Pennsylvania law in effect at
    [J-35-2016] - 33
    the time of enactment, proceeds from the sale of trust assets are part of the corpus of
    the trust. See, e.g., McKeown’s Estate, 
    106 A. 189
    , 190 (Pa. 1919) (“Being a sale of
    assets in the corpus of the trust, presumptively all the proceeds are principal… .”). The
    unavoidable result is that proceeds from the sale of oil and gas from Section 27’s public
    trust remain in the corpus of the trust.26
    26
    The Commonwealth Court posited that “where the drafters of the Pennsylvania
    Constitution intended to dedicate a tranche of money to a particular purpose, they did
    so expressly,” as in Article VIII, § 11(a) (relating to Motor Licensing Fund) (MVL Fund)
    and Article VIII, § 16 (relating to Land and Water Conservation and Reclamation Fund)
    (LWCR Fund). 
    PEDF, 108 A.3d at 168
    n.46. The Commonwealth urges us to adopt
    this reasoning, see Commonwealth’s Brief at 40, but we are unpersuaded. As
    described herein, the creation of a trust in the Environmental Rights Amendment
    obviates the need for additional language indicating that funds should be dedicated for a
    specific purpose. Section 27 itself establishes that the purpose of the trust is to
    “conserve and maintain” the public natural resources and basic trust principles require
    that the proceeds from their sale remain part of the corpus. By contrast, the MVL Fund
    and the LWCR Fund provisions do not contain trust language.
    The Commonwealth additionally urges us to adopt a line of reasoning it claims is
    consistent not with the treatment of trust proceeds under Pennsylvania trust law but,
    instead, with the “public trust doctrine.” 
    Id. at 43-45
    (discussing the seminal public trust
    doctrine case, Illinois Central Railroad Co. v. Illinois, 
    146 U.S. 387
    (1892), wherein the
    United States Supreme Court held that Illinois could not divest itself of certain land and
    water because doing so would deprive the public of its right to the use and enjoyment
    thereof). The Commonwealth’s argument is unavailing.
    As an initial matter, Illinois Central Railroad has nothing to do with the proper treatment
    of proceeds from the sale of trust assets. More to the point, while we appreciate that
    Section 27 establishes a public trust, we also recognize that the “public trust doctrine”
    does not set forth universally applicable black letter law and that Pennsylvania has no
    established public trust principles applicable to Section 27. Scholars of public trust law,
    including Professor Joseph L. Sax – whose article, The Public Trust Doctrine in Natural
    Resource Law: Effective Judicial Intervention, 
    68 Mich. L
    . Rev. 471 (1970), is discussed
    in the legislative history for Section 27 – acknowledge that the “amorphous” public trust
    concept merely provides a potential tool through which citizens may attempt to develop
    a comprehensive approach to natural resource management.

    546
    (presenting a compendium of public trust cases from around the country reflecting legal
    theories “as diverse as lawyers’ imaginations are fertile”); see also Commonwealth’s

    (continued…)
    [J-35-2016] - 34
    Second, the Commonwealth insists that the concluding phrase of Section 27, “for
    the benefit of all the people,” confers discretion upon the General Assembly to direct the
    proceeds from oil and gas development toward any uses that benefit all the people of
    the Commonwealth, even if those uses do nothing to “conserve and maintain” our public
    natural resources. Commonwealth’s Brief at 41 (citing 
    PEDF, 108 A.3d at 168
    ). We are
    wholly unconvinced. The phrase “for the benefit of all of the people” may not be read in
    isolation and does not confer upon the Commonwealth a right to spend proceeds on
    general budgetary items. Pa. Const. art I, § 27. The Commonwealth’s fiduciary duty to
    “conserve and maintain” our public natural resources is a duty owed to the beneficiaries
    of the public trust, namely “the people, including generations yet to come,” as set forth
    in the second sentence of Section 27. 
    Id. The “people,”
    in turn, are those endowed
    with “a right to clean air, pure water, and to the preservation of the natural, scenic,
    historic and esthetic values of the environment,” as set forth in the first sentence of
    Section 27. 
    Id. Accordingly, the
      Environmental   Rights      Amendment   mandates     that   the
    Commonwealth, as a trustee, “conserve and maintain” our public natural resources in
    furtherance of the people’s specifically enumerated rights. Thus understood in context
    of the entire amendment, the phrase “for the benefit of all the people” is unambiguous
    (…continued)
    (West Pub. Co. 1977), for the proposition that “[a]ny attempt at a shorthand statement of
    the principles of public trust doctrine must come with a disclaimer: the constitutional and
    legislative variations among the states approach the infinite…”).
    At most, the public trust doctrine provides a framework for states to draft their own
    public trust provisions, which (like many trust instruments) will ultimately be interpreted
    by the state courts. In Pennsylvania, established private trust principles provide this
    Court with the necessary tools to properly interpret the trust created by Section 27.
    [J-35-2016] - 35
    and clearly indicates that assets of the trust are to be used for conservation and
    maintenance purposes. See Robinson 
    Twp., 83 A.3d at 957
    (holding that the “explicit
    terms of the trust require the government to ‘conserve and maintain’ the corpus of the
    trust”). Only within those parameters, clearly set forth in the text of Section 27, does the
    General Assembly, or any other Commonwealth entity, have discretion to determine the
    public benefit to which trust proceeds – generated from the sale of trust assets – are
    directed.
    By arguing that proceeds obtained from the sale of our natural resources are not
    part of the corpus of the trust, the Commonwealth improperly conceives of itself as a
    mere proprietor of those public natural resources, rather than as a trustee.         In the
    Commonwealth’s view, it may dispose of our public natural resources as it so chooses
    and for any purpose it so conceives, so long as such disposition broadly benefits the
    public (apparently without regard to “generations yet to come”). See Commonwealth’s
    Brief at 45. As such, it urges us to substantially diminish its fiduciary obligation to
    prevent and remedy the degradation of our natural resources. We decline to do so.
    The Foundation contends that all revenues generated by oil and gas leases
    remain in the corpus of the trust. We are without sufficient advocacy to rule on the
    correctness of this proposition. We note again that Pennsylvania trust law dictates that
    proceeds from the sale of trust assets are trust principal and remain part of the corpus
    of the trust. McKeown’s 
    Estate, 106 A. at 190
    . When a trust asset is removed from the
    trust, all revenue received in exchange for the trust asset is returned to the trust as part
    of its corpus. See Bolton v. Stillwagon, 
    190 A.2d 105
    , 109 (Pa. 1963) (explaining that
    when “the relation of trustee and [beneficiary] has once been established as to certain
    [J-35-2016] - 36
    property in the hands of the trustee, no mere change of trust property from one form to
    another will destroy the relation”). As a result, royalties – monthly payments based on
    the gross production of oil and gas at each well – are unequivocally proceeds from the
    sale of oil and gas resources. See Petitioner’s Brief for Summary Judgment, Pet. Ex. X.
    They are part of the corpus of the trust and the Commonwealth must manage them
    pursuant to its duties as trustee.
    Conversely, it is less clear how to categorize other revenue streams.                See
    generally In re Rosenblum’s Estate, 
    328 A.2d 158
    , 163 (Pa. 1974) (in a case not
    involving oil and gas leases, holding that rents from realty held by a trust have
    traditionally been treated as income (and payable directly to the trust’s beneficiaries)
    rather than principal).27 See also In re McKeown’s 
    Estate, 106 A. at 190
    ; Restatement
    (Second) of Trusts § 233; 20 Pa.C.S. § 8145. For example, the record on appeal is
    undeveloped regarding the purpose of up-front bonus bid payments, and thus no factual
    basis exists on which to determine how to categorize this revenue. While we recognize
    that the leases designate these payments, among others, as “rental payments,” such a
    classification does not shed any light on the true purpose of the payment, e.g., rental of
    a leasehold interest in the land, payment for the natural gas extracted, or some other
    purpose.    In construing Sections 1604-E and 1605-E, to the extent that the lease
    agreements reflect the generation of revenue streams for amounts other than for the
    purchase of the oil and gas extracted, it is up to the Commonwealth Court, in the first
    27
    Unlike a sale or other disposition that deprives the trust of any further benefit from
    the trust asset, at the end of a rental period, the trust retains the trust asset in its entirety
    in its corpus.
    [J-35-2016] - 37
    instance and in strict accordance and fidelity to Pennsylvania trust principles, to
    determine whether these funds belong in the corpus of the Section 27 trust.
    In this regard, it must be remembered that the Commonwealth, as trustee, has a
    constitutional obligation to negotiate and structure leases in a manner consistent with its
    Article 1, Section 27 duties. Oil and gas leases may not be drafted in ways that remove
    assets from the corpus of the trust or otherwise deprive the trust beneficiaries (the
    people, including future generations) of the funds necessary to conserve and maintain
    the public natural resources.
    On remand, the parties should be given the opportunity to develop arguments
    concerning the proper classification, pursuant to trust law, of any payments called
    “rental payments” under the lease terms.            To the extent such payments are
    consideration for the oil and gas that is extracted, they are proceeds from the sale of
    trust principal and remain in the corpus. These proceeds remain in the trust and must
    be devoted to the conservation and maintenance of our public natural resources,
    consistent with the plain language of Section 27.
    C. Need for Implementing Legislation
    The Foundation contends that Section 27 is self-executing, based in part on the
    plurality opinion in Robinson Township. Foundation’s Brief at 49-50.            While the
    Commonwealth does not take a position on this issue, the Republican Caucus, as
    amicus, argues that Section 27 is not self-executing. Republican Caucus’ Brief at 48-
    60.   It analyzes decisions from others states regarding their environmental rights
    amendments and observes that, while a few states have specific language dictating that
    [J-35-2016] - 38
    the amendment is self-executing, no state has read the language of the amendment as
    self-executing when the language does not explicitly so provide. 
    Id. at 56-60.
    The plurality in Robinson Township recognized that our prior case law has not
    resolved the issue of whether Section 27 is self-executing or whether it requires
    implementing legislation to be effective, at least in regard to an attempt to enforce the
    people’s rights against owners of private property.28 Robinson 
    Township, 83 A.3d at 964
    -65; see also Dernbach, The Potential Meanings of a Constitutional Public Trust, 45
    Envtl. L. at 474-75.
    Although refusing to speak to whether the right was self-executing for purposes
    of enforcement against private property, this Court in Payne II, nevertheless concluded
    that the trust provisions in the second and third sentences of Section 27 do not require
    legislative action in order to be enforced against the Commonwealth in regard to public
    property. In Payne II, we stated:
    There can be no question that the Amendment itself
    declares and creates a public trust of public natural
    28
    This question, regarding whether Section 27 was self-executing in regard to private
    property, divided the Court in Commonwealth v. National Gettysburg Battlefield, 
    311 A.2d 588
    (Pa. 1973), where the Commonwealth attempted to enjoin the owners of
    property adjoining the Gettysburg battlefield from constructing an observation tower
    claiming that the tower would violate the people’s right to the historic and aesthetic
    values of the site. In a plurality opinion, two justices concluded that the Section 27 claim
    should be dismissed because the provision required legislative action to be effective, 
    id. at 595;
    one justice concurred with the dismissal without opinion, id.; two justices found
    that the Commonwealth’s claim failed on the merits, while acknowledging the
    Commonwealth’s ability to act as trustee (presumably without further legislative action),
    
    id. at 595-96;
    and two justices would have granted the injunction based on Section 27,
    specifically finding the provision to be self-executing, 
    id. at 597.
    As noted in Robinson
    Township, this Court previously misstated that a plurality of the justices in Gettysburg
    concluded that the Section 27 was not self-executing in United Artists Theater Circuit,
    Inc. v. City of Philadelphia, 
    635 A.2d 612
    , 620 (Pa. 1993), when in fact only two justices
    specifically found it to require legislative action. Robinson 
    Twp., 83 A.3d at 940
    .
    [J-35-2016] - 39
    resources for the benefit of all the people (including future
    generations as yet unborn) and that the Commonwealth is
    made the trustee of said resources, commanded to conserve
    and maintain them. No implementing legislation is needed to
    enunciate these broad purposes and establish these
    relationships; the [A]mendment does so by its own ipse dixit.
    Payne 
    II, 361 A.2d at 272
    .
    Former Chief Justice Castille echoed this concept in the Robinson Township
    plurality, concluding that the Commonwealth’s obligations as trustee “create a right in
    the people to seek to enforce the obligations.” Robinson 
    Township, 83 A.3d at 974
    .29
    Accordingly, we re-affirm our prior pronouncements that the public trust provisions of
    Section 27 are self-executing.
    D. Foundation’s Challenges
    In the Commonwealth Court, the Foundation sought declarations that the
    Commonwealth has certain duties as constitutional trustee and that various acts or
    decisions by the Governor and General Assembly violated those constitutional duties.
    As noted, the challenged acts and decisions primarily relate to the propriety of the
    Commonwealth’s use of revenue generated from oil and gas leases for purposes not
    authorized by Section 27.    Also implicated is the propriety of the Commonwealth’s
    decision-making process with respect to leasing state land. See Foundation’s Reply
    Brief at 13 (arguing that leasing and selling the state park and forest land, and the oil
    and gas thereon for the purpose of generating revenue for the General Fund is improper
    because balancing the budget “is not one of the purposes of the trust”). Having
    29
    We additionally find support in Section 27’s legislative history, in which Professor
    Broughton opined that the Amendment “would immediately create rights to prevent the
    government (state, local, or an authority) from taking positive action which unduly harms
    environmental quality.” Legislative Journal–House at 2281 (Broughton Analysis).
    [J-35-2016] - 40
    determined that proceeds representing payment for extracted oil and gas remain as part
    of the corpus of our environmental public trust, and that royalties are unquestionably
    such proceeds, we are able to make specific rulings with respect to only some of the
    challenged legislation.
    Sections 1602-E and 1603-E relate exclusively to royalties. On their face, these
    amendments lack any indication that the Commonwealth is required to contemplate, let
    alone reasonably exercise, its duties as the trustee of the environmental public trust
    created by the Environmental Rights Amendment. The Commonwealth itself readily
    acknowledges that revenue generated by oil and gas leases is now spent in a multitude
    of ways entirely unrelated to the conservation and maintenance of our public natural
    resources.   See Commonwealth’s Brief at 46.       Section 1602-E merely requires the
    General Assembly to “consider” allocating these funds to municipalities impacted by a
    Marcellus well. Section 1603-E limits DCNR’s allocation from the Lease Fund to “up to
    $50,000,000” from royalties and requires DCNR to “give preference to the operation and
    maintenance of State parks and forests” rather than to conservation purposes.30 Again,
    however, there is no indication that the General Assembly considered the purposes of
    the public trust or exercised reasonable care in managing the royalties in a manner
    consistent with its Section 27 trustee duties.
    30
    We reject the Commonwealth Court’s re-framing of the Foundation’s challenge to
    Section 1603-E as a contention that the General Assembly is failing to fund DCNR’s
    mission adequately under Section 27. See 
    PEDF, 108 A.3d at 161
    . Properly
    understood, the Foundation’s challenge relates to whether Section 1603-E reflects the
    appropriate exercise of the Commonwealth’s fiduciary obligations as the Section 27
    trustee, not whether DCNR’s budget is sufficient. See 
    id. (quoting Foundation’s
    Brief to
    Commonwealth Court at 93-94); see also Foundation’s Reply Brief at 7.
    [J-35-2016] - 41
    We hold, therefore, that sections 1602-E and 1603-E, relating to royalties, are
    facially unconstitutional.31   They plainly ignore the Commonwealth’s constitutionally
    imposed fiduciary duty to manage the corpus of the environmental public trust for the
    benefit of the people to accomplish its purpose – conserving and maintaining the corpus
    by, inter alia, preventing and remedying the degradation, diminution and depletion of our
    public natural resources.32 See Robinson 
    Twp., 83 A.3d at 957
    . Without any question,
    these legislative enactments permit the trustee to use trust assets for non-trust
    purposes, a clear violation of the most basic of a trustee’s fiduciary obligations. 
    Id. at 978
    (“[T]he trustee may use the assets of the trust only for purposes authorized by the
    trust or necessary for the preservation of the trust; other uses are beyond the scope of
    31
    A statute is facially unconstitutional only where no set of circumstances exist under
    which the statute would be valid. Clifton v. Allegheny Cty., 
    969 A.2d 1197
    , 1222 (Pa.
    2009) (citing Wash. State Grange v. Wash. State Republican Party, 
    552 U.S. 442
    , 449
    (2008)). “In determining whether a law is facially invalid, [a court] must be careful not to
    go beyond the statute's facial requirements and speculate about ‘hypothetical’ or
    ‘imaginary’ cases.” United States v. Raines, 
    362 U.S. 17
    , 22 (1960) (“The delicate
    power of pronouncing an Act of Congress unconstitutional is not to be exercised with
    reference to hypothetical cases thus imagined.”)). A facial challenge “must fail where
    the statute has a ‘plainly legitimate sweep.’” 
    Clifton, 969 A.2d at 1222
    (quoting 
    Grange, 552 U.S. at 449
    ).
    32
    The Commonwealth avers that robust lease terms, pre-leasing analysis, and
    monitoring programs to discover the impacts of leasing justify the Commonwealth’s
    appropriation of proceeds for non-trust purposes. See Commonwealth’s Brief at 33-
    34. These “justifications” do not answer the question of whether it is proper for the
    Commonwealth to spend proceeds from those leases on anything other than
    “remedy[ing] the degradation, diminution or depletion” of our public natural
    resources. The Foundation, conversely, takes the position that there is a “backlog of
    projects necessary to conserve and maintain our State Forests and Parks that are
    estimated to cost several billion dollars.” Foundation’s Brief at 72. The
    Commonwealth’s generalized assertions and the Foundation’s staggering estimates do
    not provide any basis to determine whether the appropriations to the General Fund
    were made pursuant to the proper exercise of the Commonwealth’s fiduciary duties as
    trustee. Moreover, the Commonwealth’s public natural resources extend beyond the
    geographic boundaries of our state parks and forests.
    [J-35-2016] - 42
    the discretion conferred, even where the trustee claims to be acting solely to advance
    other discrete interests of the beneficiaries.”); see also 20 Pa.C.S. §7780 (providing that
    the duty to administer a trust with prudence involves “considering the purposes” of the
    trust and “the exercise of reasonable care, skill, and caution”).        To the extent the
    remainder of the Fiscal Code amendments transfer proceeds from the sale of trust
    assets to the General Fund, they are likewise constitutionally infirm.
    Based on its conclusion that no revenue from the leasing and sale of trust assets
    is part of the corpus of the trust as well as its interpretation of Section 27’s plain
    language, including the Commonwealth’s fiduciary obligations that arise therefrom, the
    Commonwealth Court denied the Foundation’s application for summary relief.               It
    erroneously concluded that all of the General Assembly’s transfers and appropriations
    from the Lease Fund were wholly proper because they appeared generally to benefit all
    the people of the Commonwealth and “there is no constitutional mandate that monies
    derived from the leasing of State lands for oil and gas development be reinvested into
    the conservation and maintenance of the Commonwealth’s natural resources.” 
    PEDF, 108 A.3d at 169
    .
    Having established, to the contrary, that all proceeds from the sale of our public
    natural resources are part of the corpus of our environmental public trust and that the
    Commonwealth must manage the entire corpus according to its fiduciary obligations as
    trustee, the Commonwealth Court’s decision cannot stand.          In light of our specific
    holding that sections 1602-E and 1603-E are facially unconstitutional, the pre-2008
    appropriations scheme as set forth in the Lease Fund Act and the CNRA again controls,
    with all monies in the Lease Fund specifically appropriated to the DCNR. As to the
    [J-35-2016] - 43
    remaining acts and decisions the Foundation challenges, we clarify that their
    constitutionality depends upon whether they result from the Commonwealth’s faithful
    exercise of its fiduciary duties vis a vis our public natural resources and any proceeds
    derived from the sale thereof. For example, the Governor’s ability to override decisions
    by the DCNR regarding leasing is contingent upon the extent to which he does so in a
    manner that is faithful to his trustee obligations, not his various other obligations.
    We also clarify that the legislature’s diversion of funds from the Lease Fund (and
    from the DCNR’s exclusive control) does not, in and of itself, constitute a violation of
    Section 27. As described herein, the legislature violates Section 27 when it diverts
    proceeds from oil and gas development to a non-trust purpose without exercising its
    fiduciary duties as trustee. The DCNR is not the only agency committed to conserving
    and maintaining our public natural resources, and the General Assembly would not run
    afoul of the constitution by appropriating trust funds to some other initiative or agency
    dedicated to effectuating Section 27. By the same token, the Lease Fund is not a
    constitutional trust fund and need not be the exclusive repository for proceeds from oil
    and gas development.       However, if proceeds are moved to the General Fund, an
    accounting is likely necessary to ensure that the funds are ultimately used in
    accordance with the trustee’s obligation to conserve and maintain our natural resources.
    The Commonwealth (including the Governor and General Assembly) may not
    approach our public natural resources as a proprietor, and instead must at all times
    fulfill its role as a trustee. Because the legislative enactments at issue here do not
    reflect that the Commonwealth complied with its constitutional duties, the order of the
    Commonwealth Court with respect to the constitutionality of 1602-E and 1603-E is
    [J-35-2016] - 44
    reversed, and the order is otherwise vacated in all respects. The case is remanded to
    the Commonwealth Court for further proceedings consistent with this Opinion.
    Justices Todd, Dougherty and Wecht join the opinion.
    Justice Baer files a concurring and dissenting opinion.
    Chief Justice Saylor files a dissenting opinion.
    Former Justice Eakin did not participate in the consideration or decision of this
