    SUMMARY**
    Due Process / Application of State Law
    The panel reversed the district court’s partial dismissal of
    an antitrust action alleging a global conspiracy to fix the
    prices of LCD panels.
    The panel held that with respect to state-law claims based
    on purchases that occurred outside California, the defendants’
    alleged underlying conduct involved not just the indirect
    purchase of price-fixed goods, but also the conspiratorial
    conduct that led to the sale of those goods. Accordingly, to
    the extent a defendant’s conspiratorial conduct was
    sufficiently connected to California, and was not “slight and
    casual,” the application of California antitrust law to that
    conduct would be neither arbitrary nor fundamentally unfair,
    and would not violate the Due Process Clause.

    OPINION
    M. SMITH, Circuit Judge:
    The district court has certified to us pursuant to 
    28 U.S.C. § 1292
    (b) “the question whether the application of California
    antitrust law to claims against defendants based on purchases
    that occurred outside California would violate the Due
    Process Clause of the United States Constitution.” Because
    the underlying conduct in this case involves not just the
    indirect purchase of price-fixed goods, but also the
    conspiratorial conduct that led to the sale of those goods, we
    answer in the negative. To the extent a defendant’s
    conspiratorial conduct is sufficiently connected to California,
    and is not “slight and casual,” the application of California
    law to that conduct is “neither arbitrary nor fundamentally
    unfair,” and the application of California law does not violate
    that defendant’s rights under the Due Process Clause. See
    Allstate Ins. Co. v. Hague, 
    449 U.S. 302
    , 312–13 (1981).
    We therefore reverse the district court’s order dismissing
    Plaintiffs’ California law claims,1 and remand for further
    proceedings consistent with this opinion.
    1
    W e focus on Plaintiffs’ claims under the California Cartwright Act,
    
    Cal. Bus. & Prof. Code §§ 16700
    –16770 (Cartwright Act or Act), but the
    principles articulated herein apply equally to Plaintiffs’ claims under
    California’s Unfair Competition Law, 
    Cal. Bus. & Prof. Code §§ 17200
    et seq. (UCL). The UCL provides a cause of action for harms caused by
    “any unlawful, unfair or fraudulent business act or practice.” 
    Id.
     It thereby
    “‘borrows’ violations from other laws by making them independently
    actionable as unfair competitive practices.” Korea Supply Co. v. Lockheed
    M artin Corp., 
    63 P.3d 937
    , 943 (Cal. 2003). Because a violation of the
    Cartwright Act is, by definition, actionable under the UCL, we do not
    belabor our analysis in this case with respect to Plaintiffs’ UCL claims.

    BACKGROUND AND PROCEDURAL HISTORY
    Plaintiffs-Appellants AT&T Mobility LLC, AT&T
    Corporation, AT&T Services, Inc., BellSouth
    Telecommunications, Inc., Pacific Bell Telephone Company,
    AT&T Operations, Inc., AT&T Datacomm, Inc., and
    Southwestern Bell Telephone Company (collectively,
    Plaintiffs) are entities that provide voice and data
    communication services, and also sell mobile wireless
    handsets. Collectively, they do business in many parts of the
    world, including in California, though only one of them
    alleges that its principal place of business is located in
    California. Defendants-Appellees AU Optronics Corporation
    of America, Inc., Chi Mei Corporation, Chi Mei
    Optoelectronics Corporation, Chi Mei Optoelectronics USA,
    Inc., CMO Japan Co., Ltd., Nexgen Mediatech, Inc., Nexgen
    Mediatech USA, Inc., Chunghwa Picture Tubes Ltd., Tatung
    Company of America, Inc., Epson Imaging Devices
    Corporation, Epson Electronics America, Inc., and Hannstar
    Display Corporation (collectively, Defendants)2 are
    manufacturers and distributors of liquid crystal display (LCD)
    panels, whose respective headquarters and principal places of
    business are located in Asia and the United States, including
    California. Plaintiffs allege that between 1996 and 2006, they
    purchased billions of dollars worth of mobile handsets
    containing Defendants’ LCD panels. They further allege that
    the prices they paid for those handsets were artificially
    inflated because Defendants had orchestrated a global
    conspiracy to fix the prices of LCD panels.

    Since oral argument in this case, the parties have stipulated to the
    dismissal of this appeal with respect to a number of the Defendants.
    Defendants Chunghwa Picture Tubes Ltd., Tatung Company of America,
    Inc., and Hannstar Display Corp. remain as Appellees.

    Plaintiffs sued Defendants in the United States District
    Court for the Northern District of California under the
    Clayton Act,3 the Sherman Act,4 California’s Cartwright Act,5
    California’s UCL, and, in the alternative, the laws of a
    number of other states, seeking to recover damages caused by
    their direct and indirect purchases of LCD panels from
    Defendants. The Cartwright Act provides a private cause of
    action for indirect purchasers of price-fixed goods, whereas
    the antitrust laws of some other states do not. See Clayworth
    v. Pfizer, Inc., 
    233 P.3d 1066
    , 1082–83 (Cal. 2010)
    (discussing the effect of Ill. Brick Co. v. Illinois, 
    431 U.S. 720
    (1977), and California’s legislative response). None of
    Plaintiffs’ purchases at issue in this case was made in
    California.
    After filing their initial complaint, Plaintiffs filed a first
    amended complaint (FAC). Defendants moved to dismiss
    Plaintiffs’ California law claims in the FAC on the ground
    that the Due Process Clause of the Fourteenth Amendment
    forbids the application of California law to those claims. The
    district court granted Defendants’ motion to dismiss, holding
    that the Due Process Clause requires that “in order to invoke
    the various state laws at issue, plaintiffs must be able to
    allege that ‘the occurrence or transaction giving rise to the
    litigation’—plaintiffs’ purchases of allegedly price-fixed
    goods—occurred in the various states.”

    The district court granted Plaintiffs leave to amend their
    complaint to specify each state in which the “purchases of
    price-fixed goods” were made. In this second amended
    complaint (SAC), Plaintiffs also included more detailed
    allegations regarding Defendants’ California conduct that
    they claimed violated California law. They alleged that
    “defendants engaged in and implemented their conspiracy in
    the U.S. through the offices they maintained in California,”
    and that Defendants entered into agreements to fix the prices
    of LCD panels in California. Plaintiffs offered significant
    detail as to what conspiratorial conduct took place in
    California. They alleged, for example, that specific
    employees of particular Defendants, operating from offices in
    California, participated in illegally obtaining and sharing their
    co-conspirators’ pricing information.
    Defendants moved to dismiss the SAC, in response to
    which Plaintiffs maintained that “they may pursue all of their
    claims under California law because defendants’ price-fixing
    conduct in California creates the significant contacts between
    California and plaintiffs’ claims required by Due Process.”
    The district court disagreed, and dismissed Plaintiffs’
    California law claims that were not based on purchases that
    took place in California.
    The district court granted Plaintiffs’ motion to certify the
    dismissal order for immediate appeal under 
    28 U.S.C. § 1292
    (b), and we granted permission to appeal.
    STANDARD OF REVIEW
    We review de novo a dismissal for failure to state a claim
    pursuant to Federal Rule of Civil Procedure 12(b)(6). Frey
    v. California., 
    982 F.2d 399
    , 401 (9th Cir. 1993). We also

    “review de novo questions of law, including due process
    claims.” Buckingham v. Sec’y of U.S. Dept. of Agr., 
    603 F.3d 1073
    , 1080 (9th Cir. 2010).
    DISCUSSION
    Plaintiffs challenge the district court’s conclusion that it
    violates Defendants’ due process rights to apply California
    antitrust law to claims involving the purchase of price-fixed
    goods outside of California. They allege that the application
    of California law to all Defendants is constitutionally
    permissible because Defendants conspired, in California and
    in violation of California law, to fix the prices of goods that
    Plaintiffs eventually purchased elsewhere.
    In its order dismissing Plaintiffs’ FAC, the district court
    grounded its due process analysis on the view that “[i]n a
    price-fixing case, the relevant ‘occurrence or transaction’ is
    the plaintiff’s purchase of an allegedly price-fixed good.”
    Accordingly, the court concluded that the application of the
    antitrust laws of any state other than the state where the
    Plaintiffs purchased the allegedly price-fixed goods would
    violate Defendants’ rights to due process. The court applied
    the same reasoning in its order dismissing Plaintiffs’ SAC,
    which we review on interlocutory appeal.
    The district court’s conclusion ignores conduct that may
    give rise to a cause of action under the Cartwright Act. A
    modern “price-fixing case” is not a creature of common law,
    but instead arises under federal antitrust laws6 or the antitrust
    6
    See, e.g., Sherman Antitrust Act, 
    15 U.S.C. §§ 1
    –7; Clayton Antitrust
    Act, 
    15 U.S.C. §§ 12
    –27, 
    29 U.S.C. §§ 52
    –53.

    laws of various states.7 The “relevant transaction or
    occurrence” for purposes of a due process analysis is
    therefore informed, at least in part, by the scope of conduct
    that gives rise to liability under the relevant statutes. A
    reading of the plain text of the Cartwright Act reveals that the
    district court’s place-of-purchase focus severely truncates the
    scope of anticompetitive conduct that the Act proscribes.
    The Cartwright Act enumerates a relatively broad array of
    anticompetitive and conspiratorial conduct that constitutes a
    “trust.” 
    Cal. Bus. & Prof. Code § 16720
    . The Act declares
    that “every trust is unlawful, against public policy and void,”
    
    id.
     § 16726, and provides a private right of action to “[a]ny
    person who is injured in his or her business or property by
    reason of anything forbidden or declared unlawful by this
    chapter,” id. § 16750.8 The unlawful activities described in
    section 16720 include the sale of price-fixed goods in
    California. Id. § 16720(d). But that section includes other
    conduct, such as the initial agreement to fix those
    prices—without reference to where those goods will
    eventually be sold. As the California Supreme Court has
    explained:
    The Act also reaches deep in proscribing
    anticompetitive conduct: it prohibits two or
    more persons “[t]o make or enter into or
    7

    antitrust law . . . .” Stephen Calkins, Perspectives on State and Federal
    Antitrust Enforcement, 
    53 Duke L.J. 673
    , 678 (2003).

    The question of whether the Cartwright Act provides a cause of action
    based exclusively on out-of-state purchases is distinct from the inquiry of
    whether such an application would violate the Due Process Clause, and is
    not at issue in this case.

    or agreements of any kind or description, by

    directly or indirectly unite any interests that
    they may have connected with the sale or
    transportation of any . . . article or
    commodity, that its price might in any manner
    be affected.” (Bus. & Prof.Code, § 16720,
    subd. (e)(4), italics added.) In so doing, the
    Act reaches beyond the Sherman Act to
    threats to competition in their incipiency . . . .
    Cianci v. Superior Court, 
    710 P.2d 375
    , 383 (Cal. 1985)
    (ellipses and alterations in original); see also Knevelbaard
    Dairies v. Kraft Foods, Inc., 
    232 F.3d 979
    , 986 (9th Cir.
    2000) (“Under both California and federal law, agreements
    fixing or tampering with prices are illegal per se.” (quoting
    Oakland-Alameda Cnty. Builders’ Exch. v. F. P. Lathrop
    Constr. Co., 
    482 P.2d 226
    , 232 (Cal. 1971) (in bank))).
    Rightly understood then, the “transaction or occurrence”
    proscribed by the Cartwright Act includes not only the sale of
    price-fixed goods, but the full extent of incipient
    conspiratorial conduct described in section 16720 of the Act.
    Defendants argue that the application of California law
    would nonetheless violate their due process rights because
    Plaintiffs’ purchases of price-fixed goods all took place
    outside of California. However, the United States Supreme
    Court held long ago that “[o]bjections which are founded
    upon the Fourteenth Amendment must . . . be directed[] not
    to the existence of the power to impose liability for an injury
    outside state borders, but to the manner of its exercise as
    being so arbitrary or unreasonable as to amount to a denial of
    due process.” Alaska Packers Ass’n v. Indus. Accident
    AT&T MOBILITY LLC V . AU OPTRONICS CORP .                          11
    Comm’n, 
    294 U.S. 532
    , 541–42 (1935) (applying California
    Workmen’s Compensation Act to injuries sustained while
    employee was working in Alaska, where employment
    contract was executed in California). Articulating what
    would amount to a denial of due process in that context, the
    Court later explained that “for a State’s substantive law to be
    selected in a constitutionally permissible manner, that State
    must have a significant contact or significant aggregation of
    contacts, creating state interests, such that choice of its law is
    neither arbitrary nor fundamentally unfair.” Allstate Ins. Co.
    v. Hague, 
    449 U.S. 302
    , 312–13 (1981).9 The Due Process
    Clause thus requires a court to invalidate the application of a
    state’s law only where the state has “no significant contact or
    significant aggregation of contacts, creating state interests,
    with the parties and the occurrence or transaction.” See 
    id. at 308, 320
    .
    In Allstate, the Court upheld the application of Minnesota
    insurance law to an insurance policy delivered in Wisconsin
    to a Wisconsin resident who subsequently died in an
    automobile accident that took place in Wisconsin and
    involved another Wisconsin resident. 
    Id. at 320
    . Following
    the accident, the decedent’s wife moved to Minnesota and
    brought suit against the insurer in Minnesota court seeking a
    declaration that Minnesota law applied to her late husband’s
    automobile insurance policy. 
    Id.
     at 305–06. The Minnesota
    Supreme Court upheld the application of Minnesota insurance
    law, and the United States Supreme Court affirmed. 
    Id.
     at
    9
    Though Allstate was a plurality opinion joined by four of the eight
    justices who heard the case, “[t]he dissenting Justices were in substantial
    agreement with this principle,” and the Court later ratified it as controlling
    precedent. See Phillips Petroleum Co. v. Shutts, 
    472 U.S. 797
    , 818–19,
    821–22 (1985).
    12     AT&T MOBILITY LLC V . AU OPTRONICS CORP .
    306–07, 320. The plurality cited three contacts Minnesota
    had with the case and the parties: (1) the plaintiff’s husband’s
    daily commute to Minnesota and his membership in that
    state’s workforce prior to his death; (2) Allstate’s general
    business presence in Minnesota; and (3) the plaintiff’s
    Minnesota residency. 
    Id.
     at 313–20.
    As the somewhat tenuous nature of the Minnesota
    contacts illustrates, the Court’s decision in Allstate places
    only “modest restrictions on the application of forum law,”
    Shutts, 
    472 U.S. at 818
    , and most commentators have viewed
    Allstate as setting a highly permissive standard.10 Neither the
    purchase and delivery of the relevant insurance policy nor the
    automobile accident that the plaintiff sought to recover on
    occurred in Minnesota. By comparison, Plaintiffs claim that
    some portion of Defendants’ alleged illegal price-fixing
    conduct took place within California. Wherever the outer
    limit of due process constraints may lie, it is clear to us that
    Defendants’ alleged illegal activity within California created
    more significant contacts with California than the contacts
    described in Allstate created with Minnesota.
    In contrast to the broad scope of the Allstate plurality’s
    search for contacts, the district court’s guiding principle
    makes a single contact—the location of Plaintiffs’
    injury—dispositive. Put differently, the district court’s place-

    and Fifth Amendment Due Process,

    AT&T MOBILITY LLC V . AU OPTRONICS CORP .                      13
    of-purchase rule represents a return to the “wooden” and
    “now largely abandoned” lex loci delicti doctrine—an
    approach the plurality explicitly rejected in Allstate. See
    Allstate, 
    449 U.S. at
    316 n.22. The raison d’etre of choice of
    law analysis, particularly in the context of tort-like suits,11 is
    the common understanding that “a set of facts giving rise to
    a lawsuit, or a particular issue within a lawsuit, may justify,
    in constitutional terms, application of the law of more than
    one jurisdiction.” Allstate, 
    449 U.S. at 307
    ; see also Shutts,
    
    472 U.S. at 823
     (“[I]n many situations a state court may be
    free to apply one of several choices of law.”). We see no
    reason why the due process constraints on the application of
    state antitrust law should, unlike any other area of law, follow
    the obsolete lex loci delicti rule.
    Instead, the relevant “occurrence or transaction” in this
    case includes not only the sale of price-fixed goods, but
    Defendants’ alleged agreements and conspiracies to fix LCD
    prices. Accordingly, the district court should have considered
    all of the Defendants’ conduct within California leading to
    the sale of price-fixed goods outside the state when
    determining whether California law could be applied without
    offending Defendants’ due process rights. See, e.g., Mazza v.
    Am. Honda Motor Co., 
    666 F.3d 581
    , 590 (9th Cir. 2012)
    (“California has a constitutionally sufficient aggregation of
    contacts to the claims of each putative class member in this
    [fraudulent misrepresentation] case because Honda’s

    See Restatement (Second) of Conflict of Laws § 145 (1971) (when
    determining what state has the most significant relationship to the
    occurrence and the parties, contacts to consider include: the place where
    the injury occurred; the place where the conduct causing the injury
    occurred; the domicile, residence, nationality, place of incorporation and
    place of business of the parties; and the place where the relationship, if
    any, between the parties is centered).

    corporate headquarters, the advertising agency that produced
    the allegedly fraudulent misrepresentations, and one fifth of
    the proposed class members are located in California.”);
    Sullivan v. Oracle Corp., 
    662 F.3d 1265
    , 1270–71 (9th Cir.
    2011) (relying on both the location of defendant’s
    headquarters and the fact that “the decision to classify
    Plaintiffs as teachers and to deny them overtime pay was
    made in California,” to conclude that the contacts were
    “clearly sufficient” to apply California law to work performed
    within California by nonresident employees). Thus, in-state
    conduct that causes out-of-state injuries can be relevant to a
    due process analysis, in the antitrust context and otherwise.
    Finally, we conclude that the perpetration of
    anticompetitive activities within California “creat[es] state
    interests” in applying California law to that conduct. See
    Allstate, 
    449 U.S. at 308, 320
    . While Defendants argue that
    the purpose of antitrust laws is to compensate consumers, the
    Supreme Court of California has found otherwise with respect
    to the Cartwright Act:
    From its inception, the Cartwright Act has
    always been focused on the punishment of
    violators for the larger purpose of promoting
    free competition. It is, like antitrust laws
    generally, about the protection of competition,
    not competitors. Private damage awards are
    just a tool by which these procompetitive
    purposes are carried out . . . .
    Clayworth, 
    233 P.3d at 1083
     (internal quotations and citations
    omitted). Applying California law to anticompetitive conduct

    Nor would the application of California law
    impermissibly undermine the policies of other states, as
    Defendants contend. Because the Due Process Clause does
    nothing but circumscribe the universe of state laws that can
    be constitutionally applied to a given case, we “need not . . .
    balance the competing interests of California and [other
    states].” United Farm Workers of Am., AFL-CIO v. Ariz.

    669 F.2d 1249

    308 n.10 (“[T]he Court
    has since abandoned the weighing-of-interests requirement.”).
    Objections based on the interests of other states are more
    properly raised under a choice of law analysis,12 or potentially
    under a challenge predicated on some other provision of the
    U.S. Constitution.13 Defendants raised no such arguments
    before the district court.

    “Questions of legislative jurisdiction have not often played a

    Scheme,

    In light of the above, we conclude that anticompetitive
    conduct by a defendant within a state that is related to a
    plaintiff’s alleged injuries and is not “slight and casual”14
    establishes a “significant aggregation of contacts, creating
    state interests, such that choice of its law is neither arbitrary
    nor fundamentally unfair.” Allstate, 
    449 U.S. at
    112–13.
    Specifically, we hold in this case that the Cartwright Act can
    be lawfully applied without violating a defendant’s due
    process rights when more than a de minimis amount of that
    defendant’s alleged conspiratorial activity leading to the sale
    of price-fixed goods to plaintiffs took place in California.
    Such a defendant cannot reasonably complain that the
    application of California law is arbitrary or unfair when its
    alleged conspiracy took place, at least in part, in California.15
    See Shutts, 
    472 U.S. at 822
     (“When considering fairness in
    this context, an important element is the expectation of the
    parties.”); Allstate, 
    449 U.S. at
    317–18 (“By virtue of its
    presence, Allstate can hardly claim unfamiliarity with the
    laws of the host jurisdiction and surprise that the state courts
    might apply forum law to litigation in which the company is
    involved.”).
    CONCLUSION
    “A state court is rarely forbidden by the Constitution to
    apply its own state’s law,” Sullivan,

    As the district court has already noted, the requirements of the Due
    Process Clause must be satisfied individually with respect to each
    defendant in a case. Cf. Shutts, 
    472 U.S. at
    821–22 (contacts must be
    related to each member of the plaintiff class).

    violations of a state’s law that allegedly occurred within that
    state. The relevant transaction or occurrence in a price-fixing
    case involves both the conspiracy to illegally fix prices and
    the sale of price-fixed goods. The district court therefore
    erred in holding that the Due Process Clause will permit the
    application of California law in a price-fixing case only when
    a plaintiff purchased the price-fixed goods in California.
    We reverse the district court’s order dismissing Plaintiffs’
    claims under the Cartwright Act and the UCL. We remand to
    the district court for it to make an individual determination
    consistent with this opinion with respect to each Defendant as
    to whether Plaintiffs have alleged sufficient conspiratorial
    conduct within California, that is not “slight and casual,” such
    that the application of California law to that Defendant is
    “neither arbitrary nor fundamentally unfair.”
