  • In the Matter of Mark McCloy, Case No. 673, September Term 2022. Opinion filed on
    May 1, 2023, by Berger, J.
    DISQUALIFYING CRIME – STATUTORY INTERPRETATION – QUESTION OF
    LAW – DE NOVO STANDARD OF REVIEW
    Under Maryland’s firearms regulations, the determination of whether an out-of-state
    conviction constitutes a “disqualifying crime” under Section 5-101(g) of Maryland’s
    Public Safety Article is a matter of statutory interpretation, and, therefore, it is a question
    of law reviewed de novo.
    DISQUALIFYING CRIME – OUT-OF-STATE CONVICTION – EQUIVALENCE TO
    MARYLAND STATUTE
    Under Maryland’s firearms regulations, an out-of-state conviction is a “disqualifying
    crime” that prohibits an applicant from obtaining a handgun qualification license if the
    Maryland State Police determine that the foreign statute providing the basis for the out-of-
    state conviction is equivalent to a Maryland misdemeanor statute with a penalty in excess
    of two years’ imprisonment.
    DISQUALIFYING CRIME – OUT-OF-STATE CONVICTION – TIMING OF
    COMPARISON
    When assessing whether an out-of-state conviction is a “disqualifying crime,” the foreign
    statute providing the basis for the out-of-state conviction must be compared to the
    purportedly equivalent Maryland statute as it existed at the time of the application, not as
    it existed at the time of the out-of-state conviction. If the Maryland statute did not exist at
    the time of the out-of-state conviction, that does not preclude a finding of equivalency.
    What controls is whether the Maryland statute, at the time of the application, is a
    misdemeanor with a maximum penalty of more than two years’ imprisonment.
    DISQUALIFYING CRIME – EQUIVALENCY DETERMINATION
    To affirm the Maryland State Police’s determination that an out-of-state-conviction is
    equivalent to a Maryland misdemeanor statute with a penalty in excess of two years’
    imprisonment such that the out-of-state conviction is a “disqualifying crime” prohibiting
    an applicant from obtaining a handgun qualification permit, a reviewing court must
    conclude that a reasonable mind could find (1) that the statutes prohibit similar conduct,
    based on the comparison of the elements of each statute, and (2) that the conduct producing
    the out-of-state conviction would be prohibited by the purportedly comparable Maryland
    statute.
    REVIEW OF ADMINISTRATIVE AGENCY DECISION – MODIFIYING AND
    AFFIRMING AGENCY DECISION
    When reviewing an administrative law judge’s (“ALJ”) findings, if a circuit court reaches
    the same conclusion as the ALJ, but does so on different grounds than the ALJ, then the
    circuit court may modify the ALJ’s decision while affirming the ALJ’s conclusion.
    ESTOPPEL – ENFORCEMENT OF REGULATORY MEASURES
    The prior approval of a handgun qualification license (“HQL”) does not estop the Maryland
    State Police (“MSP”) from denying a subsequent HQL application from the same applicant,
    despite no substantive changes to the applicant’s criminal record between the submission
    of each application. The MSP’s failure to properly assess an applicant’s prior criminal
    conviction as a disqualifying crime does not preclude the agency from making such a
    determination upon a subsequent HQL application.
    EX POST FACTO – EQUIVALENCY DETERMINATION – REGULATORY
    PROVISIONS
    The determination that an out-of-state conviction is equivalent to a comparable Maryland
    criminal statute, not in existence at the time of the out-of-state conviction, such that the
    out-of-state conviction is a “disqualifying crime” under Maryland’s firearms regulations,
    does not violate the ex post facto prohibitions of the United States and Maryland
    constitutions. The firearms regulations are civil in character and prohibit current
    possession of firearms; therefore, they are distinct from retroactive criminal prohibitions
    of prior conduct.
    DUE PROCESS – COLLATERAL CONSEQUENCES OF PRIOR CONVICTION
    A defendant failing to receive notice that, as a consequence of his entering of a guilty plea
    in a foreign jurisdiction, he may be precluded from exercising his constitutional right to
    bear arms, does not preclude the Maryland State Police from denying the defendant’s
    application for a handgun qualification license.

    Gregory Hilton, Clerk
    *At the November 8, 2022 general election, the voters of Maryland ratified a constitutional
    amendment changing the name of the Court of Special Appeals of Maryland to the
    Appellate Court of Maryland. The name change took effect on December 14, 2022.
    This appeal arises from Appellee’s, the Maryland State Police (“the MSP”), denial
    of Appellant Mark McCloy’s (“McCloy”) application to purchase a handgun. The MSP
    determined that McCloy’s 1999 conviction under a federal witness tampering statute
    qualified as a “disqualifying crime” that prohibited him from possessing a regulated
    firearm under Maryland law.         The Office of Administrative Hearings (“the OAH”)
    reviewed the decision, and an administrative law judge (“ALJ”) affirmed the denial of the
    application. McCloy sought judicial review in the Circuit Court for Queen Anne’s County.
    The circuit court affirmed the ALJ’s decision, but on different grounds. This appeal
    followed.
    McCloy presents four questions for our review, which we rephrase into two
    questions, as follows:1
    1
    McCloy presents the following questions, verbatim, for our review:
    1.     Whether the Circuit Court committed errors of law,
    abused its discretion, or violated the constitutional
    rights of the Appellant when it found that the version of
    
    18 U.S.C. § 1512
    (c)(1) in effect in 1999 is equivalent to
    [Section 9-305 of Maryland’s Criminal Law Article],
    when it failed to conduct any comparative analysis of
    the elements of the two offenses?
    2.     Whether it is violative of the [United States] and
    Maryland Constitutions to deny Appellant the purchase
    of a regulated firearm on the basis of the current penalty
    for an offense he was not convicted of, and for which
    the agency has previously and repeatedly determined is
    not equivalent to the convicted offense?
    3.     Whether the Office of Administrative Hearings’
    Decision and Order are arbitrary and capricious and
    I.    Whether the circuit court erred in affirming the MSP’s
    denial of McCloy’s application to purchase a regulated
    firearm.
    II.   Whether the circuit court erred in determining that
    McCloy was not entitled to equitable relief from the
    denial of his application to purchase a regulated firearm.
    For the reasons explained herein, we answer both of these questions in the negative.
    We, therefore, affirm the circuit court’s ruling that the MSP correctly denied McCloy’s
    application.
    FACTS AND PROCEDURAL HISTORY
    Maryland’s Handgun Regulation and Application Process
    A “handgun qualification license” (“HQL”) is “a license issued by [the MSP] that
    authorizes a person to purchase, rent, or receive a handgun.” Md. Code (2003, 2022 Repl.)
    § 5-101(o) of the Public Safety Article (“PS”). A person must submit, and have approved,
    an application for an HQL before purchasing, renting, or transferring a regulated firearm.
    Id. § 5-117. The application shall contain a statement from the applicant, made under
    penalty of perjury, that the applicant has never been convicted of a “disqualifying crime,”
    or of a common law crime resulting in imprisonment for more than two years. Id. § 5-
    118(b)(3). Upon the receipt of the application, the Secretary of the MSP must promptly
    lack the support of competent, material, and substantial
    evidence?
    4.    Whether the Office of Administrative Hearings violated
    the principles of lenity, estoppel, and Ex Post Facto?
    2
    investigate “the truth or falsity of the information supplied” and determine whether the
    applicant may purchase a regulated firearm. Id. § 5-121(a); Md. Code Regs. (“COMAR”)
    29.03.01.18(A).
    “[A] person may not possess a regulated firearm if the person has been convicted of
    a disqualifying crime.” PS § 5-133(b)(1). “[A] ‘[d]isqualifying crime’ means: (1) a crime
    of violence; (2) a violation classified as a felony in the State; or (3) a violation classified
    as a misdemeanor in the State that carries a statutory penalty of more than [two] years.”
    Id. § 5-101(g). The MSP, as the agency tasked with reviewing HQL applications, “may
    properly deny a handgun permit to anyone who has [been determined to have committed]
    a disqualifying crime under PS § 5–101(g) and is [thereby] prohibited from possessing a
    handgun under PS § 5-133(b)(1).” Brown v. Handgun Permit Rev. Bd., 
    188 Md. App. 455
    ,
    471 (2009).
    McCloy’s 1999 Federal Conviction
    While working as a government employee in 1999, McCloy and a fellow employee
    engaged in sex at McCloy’s home in Chester, Maryland. McCloy gave the fellow
    employee $200. Shortly thereafter, the woman filed a complaint against McCloy with the
    Equal Employment Opportunity Commission (“EEOC”) alleging sexual harassment. The
    fellow employee later called McCloy and offered to dismiss her complaint in exchange for
    McCloy paying her $5,000. McCloy advised the fellow employee that McCloy could not
    afford that amount, but he counteroffered $1,000 for the employee to dismiss the
    3
    complaint, to which she agreed.2
    Unbeknownst to McCloy, Federal Bureau of Investigation (“F.B.I.”) agents taped
    the call. Additionally, another employee who worked in close physical proximity to
    McCloy overheard the call. Thereafter, McCloy asked that employee not to disclose or
    discuss what he had heard. McCloy was ultimately arrested. He pleaded guilty in the
    United States District Court for the District of Columbia to witness tampering, in violation
    of 
    18 U.S.C. § 1512
    (c)(1).3 McCloy was sentenced to six months of home detention
    followed by a five-year period of probation.
    McCloy’s Gun Permit Applications
    In 2015, McCloy submitted an HQL application to the MSP. The MSP initially
    denied the application. McCloy promptly appealed that denial. Before the hearing for the
    appeal, the MSP sent McCloy a letter, dated April 8, 2015, reversing its prior decision and
    2
    No EEOC proceeding ultimately occurred.
    3
    As explained by McCloy’s attorney in an affidavit, “[t]he tampering with a witness
    was the agreeing to pay [the complainant] $1,000.00 in return for her dismissing the EEOC
    complaint against him and the asking of another person to please not tell anyone what he
    had overheard.” The statute under which he was charged is titled “Tampering with a
    witness, victim, or an informant,” and it is codified amongst other “Obstruction of Justice”
    crimes in Chapter 73 of the United States Code’s Crime and Criminal Procedure Title. See
    
    18 U.S.C. § 1512
    .
    4
    approving his application.4 McCloy used this license to purchase several firearms.5
    On February 8, 2021, McCloy filed another application with the MSP to purchase a
    handgun.6 The required criminal background check conducted by the MSP detected
    McCloy’s 1999 federal conviction and sentence. On March 4, 2021, the MSP sent McCloy
    a letter informing him of the denial of his permit and of his right to appeal the decision.
    4
    The MSP asserts that no records exist documenting the reasons for the initial denial
    and the subsequent reversal of McCloy’s 2015 HQL application. At the hearing appealing
    the 2021 denial of McCloy’s HQL application, Senior Trooper David Simmons, the officer
    tasked with scrutinizing McCloy’s background and 2021 application, could not precisely
    speak to why the 2015 HQL application was approved after the initial denial. Nonetheless,
    he speculated that it may have been the result of the F.B.I. criminal background report
    provided in 2015, and the subsequent MSP investigation, not producing sufficient clarity
    and proof of the precise crime of which McCloy was convicted. Because the MSP bears
    the burden of proving that a conviction is disqualifying -- and because the MSP has a finite
    time period with which to make its determination -- Simmons explained that without a
    record showing the nature of McCloy’s conviction, “we would overturn the disapproval
    because we don’t have hard proof to show what he was convicted of and approve if this is
    a disqualifying crime.” Simmons noted, however, that regardless of the prior approval, the
    MSP can still disqualify an application if “in a subsequent background check we did catch
    the mistake,” as Simmons asserted happened in the current dispute regarding the 2021
    application.
    5
    During the OAH hearing appealing the denial of his 2021 HQL application,
    McCloy testified that he used the 2015 HQL to purchase “a 22-caliber pistol . . . two
    handguns, single action . . . two other single[-]action pistols, and a rifle . . . All of those
    were approved.”
    6
    Because McCloy’s original HQL was issued in 2015, he had to renew his permit
    to purchase additional regulated firearms in 2021. See PS § 5-309(a) (barring exception,
    “a permit expires on the last day of the holder’s birth month following [two] years after the
    date the permit is issued”).
    It appears from the record that McCloy filed his application on February 8, 2021,
    but the dealer attempting to sell McCloy the firearm completed the application on
    February 26, 2021.
    5
    McCloy sent an email to the MSP the following day requesting a formal hearing to appeal.7
    That same day, Senior Trooper David Simmons, the MSP officer assigned to review
    McCloy’s application, responded, informing McCloy that, while his federal conviction did
    not federally prohibit his possession of a firearm, the MSP determined 
    18 U.S.C. § 1512
    (c)(1) was comparable to Section 9-302 of Maryland’s Criminal Law Article (“CR”),
    and because this statute carried a penalty of up to ten years’ imprisonment, it constituted a
    “disqualifying crime” under Maryland law.8 Two days before the scheduled OAH hearing
    for the appeal, the MSP changed its position and advised McCloy that the equivalent statute
    to his federal conviction was Section 9-305(a), not Section 9-302, of the Criminal Law
    Article.9
    7
    “A person who is denied a permit or renewal of a permit or whose permit is
    revoked” may file a request for an appeal, in writing, with the MSP and the OAH within
    10 days of receiving notice of the MSP’s decision. PS § 5-312(a)(1). Within 60 days, the
    OAH shall schedule and conduct such “a de novo hearing on the matter, at which witness
    testimony and other evidence may be provided,” after which the OAH shall issue findings
    of fact and a decision. Id. § 5-312(b)(1). Any hearing or subsequent proceeding of review
    “shall be conducted in accordance with Title 10, Subtitle 2 of the State Government
    Article.” Id. § 5-312(c)(1).
    8
    Though we typically abbreviate the Articles of the Maryland Code using the first
    initials of the titles of the relevant articles, we use the naming convention “CR,” rather than
    “CL,” for the Criminal Law Article as to avoid potential confusion with the Commercial
    Law Article of the Maryland Code.
    9
    The parties dispute how long before the hearing the MSP alerted McCloy of this
    change. McCloy claims it occurred immediately prior to the hearing. The MSP claims it
    advised McCloy’s counsel two days before the hearing to the change in its position on the
    comparable statute. Because the circuit court relied on the two-day time frame, we will
    rely upon that finding, as well.
    6
    McCloy’s Appeal of the Denial of His 2021 HQL Application
    On July 21, 2021, the OAH conducted a hearing before an ALJ to review the denial
    of McCloy’s application. Separate counsel represented both the MSP and McCloy.
    McCloy’s attorney did not note an objection to the late notice of the MSP’s change in
    position regarding the equivalent “disqualifying crime.” Both parties proceeded with full
    examinations of Trooper Simmons and McCloy, the only witnesses who provided
    testimony, and further presented their respective arguments at the hearing.
    On August 6, 2021, the ALJ issued a decision affirming the disapproval of
    McCloy’s application. In so doing, the ALJ made findings of fact and conclusions of law
    distinct from the arguments presented by both the MSP and McCloy. The ALJ sua sponte
    determined that 
    18 U.S.C. § 1512
    (c)(1) was analogous to Section 9-306 of the Maryland
    Criminal Law Article, not Section 9-305(a). The ALJ concluded that because CR § 9-306
    has a maximum penalty of five years’ imprisonment (and because the federal law providing
    the basis for McCloy’s conviction is analogous to this statute), McCloy’s “misdemeanor
    conviction [in United States District Court for the District of Columbia] for tampering with
    a witness meets the definition of a disqualifying crime. . . .” The ALJ further determined
    that the MSP “correctly disapproved [McCloy’s] application to purchase a regulated
    firearm based on this prior conviction.”
    Additionally, McCloy asserts that at the beginning of the OAH hearing his attorney
    requested to submit additional briefing related to the MSP changing its equivalency
    determination from CR § 9-302 to § 9-305. Our review of the record reflects that this
    request appears to be more of a general request to supplement any arguments, as necessary,
    following the hearing, and not specifically about notice of the substantive issue of
    comparing the Maryland statutes to his conviction.
    7
    The ALJ also found that McCloy “provided false information in his application in
    the attempt to hide the [D.C.] federal conviction because it might negatively impact his
    application.” On his application, McCloy affirmed, under penalty of perjury, that he had
    not been convicted in Maryland or elsewhere of a misdemeanor which, under Maryland
    law, carries a maximum sentence of two years or more. The ALJ concluded that the MSP
    could deny McCloy’s application based on this false statement alone. See PS § 5-
    122(a)(1)–(2).
    On August 30, 2021, McCloy filed in the Circuit Court for Queen Anne’s County a
    petition for judicial review of the ALJ’s decision.10 That court held a hearing on the
    petition on March 8, 2022. On May 19, 2022, the circuit court issued a memorandum
    opinion and order affirming the denial of McCloy’s application. See Jud. Rev. of the
    Decision of the Off. of Admin. Hearings Case of Mark A. McCloy OAH No. MSP-LD-20-
    21-06628, Case No. C-17-CV-21-000138, at 1, 13 (Md. Cir. Ct. Queen Anne’s Cnty. May
    19, 2022) [hereinafter McCloy Cir. Ct. Rev.].
    Notably, the circuit court disagreed with several of the ALJ’s conclusions. Id. at 7–
    8, 11. The circuit court found that the OAH proceeding violated McCloy’s due process
    rights because the ALJ pursued a rationale for disqualification not advanced by the MSP,
    and, in so doing, deprived McCloy of the opportunity to respond to the argument that his
    federal conviction was akin to a Maryland conviction under CR § 9-306. Id. at 7.
    Additionally, the court found that the record did not support the finding that McCloy
    10
    “A party that is aggrieved by the decision of the [OAH] may appeal the decision
    to the circuit court.” PS § 5-312(b)(3).
    8
    provided a false statement on his application when he checked the “no” box in response to
    the question asking whether he had been convicted of a crime in Maryland or elsewhere
    with a maximum penalty of more than two years’ imprisonment. Id. at 7–8.
    Nonetheless, the circuit court affirmed the denial of McCloy’s application by the
    MSP. In reviewing whether the ALJ erred in rejecting the MSP’s assertion that CR § 9-
    305(a) and 
    18 U.S.C. § 1512
    (c)(1) were equivalent, the circuit court independently
    compared the statutes. 
    Id.
     at 8–11. The circuit court determined that the statutes were
    equivalent based on the common element of intent to interfere with or impede an official
    proceeding. 
    Id.
     at 10–11. Accordingly, McCloy’s federal conviction was a “disqualifying
    crime” that prohibited him from obtaining a license to possess a firearm. 
    Id.
     As a result,
    the circuit court affirmed the MSP’s denial of McCloy’s application. 
    Id. at 1
    . McCloy
    timely appealed the circuit court’s ruling to this Court.
    DISCUSSION
    Standard of Review
    “When reviewing a decision by an administrative agency, this Court ‘looks through’
    the decision of the circuit court, applying the same standards of review to determine
    whether the agency itself erred.” In re Homick, 
    256 Md. App. 297
    , 307 (2022) (quoting
    Brandywine Senior Living at Potomac LLC v. Paul, 
    237 Md. App. 195
    , 210 (2018)). The
    scope of judicial review of an agency decision is limited. Mayor & City Council of Balt. v.
    Proven Mgmt., Inc., 
    472 Md. 642
    , 667 (2021); see also Dep't of Hum. Res., Balt. City Dep't
    of Soc. Servs. v. Hayward, 
    426 Md. 638
    , 650 (2012) (“We also are mindful that this Court's
    review of an agency's decision is narrow.”). We review the agency’s conclusions of fact
    9
    under the “substantial evidence test,” which requires us to affirm the agency’s findings
    when there exists “such relevant evidence as a reasonable mind might accept as adequate
    to support a conclusion.” Proven Mgmt., Inc., supra, 
    472 Md. at 667
     (quoting Bullock v.
    Pelham Wood Apartments, 
    283 Md. 505
    , 512 (1978)). “We review questions of law de
    novo, although we give weight to an agency’s interpretation of a statute it is charged with
    enforcing where the interpretation is longstanding and falls within the agency's area of
    expertise.” Brown, supra, 188 Md. App. at 467; see also Md. St. Police v. McLean, 
    197 Md. App. 430
    , 438 (2011).
    “On the other hand, ‘a reviewing court is under no constraints in reversing an
    administrative decision which is premised solely upon an erroneous conclusion of law.’”
    Proven Mgmt., Inc., supra, 
    472 Md. at 667
     (quoting People’s Couns. v. Md. Marine Mfg.
    Co., 
    316 Md. 491
    , 497 (1989)). “When an error of law is alleged, a reviewing court is at
    liberty to substitute its judgment for that of the agency.” Regan v. Bd. of Chiropractic
    Exam’rs, 
    120 Md. App. 494
    , 511 (1998) (emphasis added), aff’d, 
    355 Md. 397
     (1999).
    Because the issue in dispute in this case is the interpretation of a statute, specifically the
    interpretation of PS § 5-101(g), the matter before us is such a question of law that we
    review de novo. McLean, supra, 197 Md. App. at 438. Further, while the determination
    of “disqualifying crimes” “falls within the agency’s area of expertise,” in the case before
    us, the MSP’s interpretation of law is not “longstanding” when considering the 2015
    approval of McCloy’s HQL application and the 2021 denial of his subsequent HQL
    application; therefore, we are not beholden to give particular “weight” to the MSP’s
    interpretation of PS § 5-101(g). Id.
    10
    I.     The Circuit Court Did Not Err by Affirming the Denial of McCloy’s HQL
    Application.
    We affirm the circuit court’s legal conclusion that McCloy’s federal conviction
    constitutes a “disqualifying crime” because the conviction is equivalent to a misdemeanor
    conviction in Maryland carrying a maximum penalty of more than two years’
    imprisonment. We further hold that the circuit court did not err in its statutorily prescribed
    role when it reviewed and modified the ALJ’s decision. Though we review the ALJ’s
    decision without deference to the circuit court’s determination, we affirm the ALJ’s ruling.
    See In re Homick, supra, 256 Md. App. at 307. Further, McCloy’s equitable arguments
    are unavailing. As such, we affirm the circuit court’s affirmance of the MSP’s denial of
    McCloy’s 2021 HQL application.
    A.     Although McCloy’s conviction occurred in 1999, the MSP correctly
    compared the federal statute under which he was convicted to an
    equivalent Maryland statute at the time McCloy submitted his permit
    application. In so doing, the circuit court correctly concluded that his
    conviction constituted a “disqualifying crime.”
    1.     McCloy argues that his 1999 conviction cannot be considered a
    disqualifying crime which bars his ability to possess a handgun.
    The denial of McCloy’s HQL application is contingent upon whether his 1999
    federal conviction was correctly classified as a “disqualifying crime.” McCloy argues that
    because his conviction occurred in 1999, it can only be compared to other Maryland
    statutes that existed in 1999. McCloy asserts that, since CR § 9-305 became effective on
    October 1, 2002, he could not have been charged or convicted under this purportedly
    equivalent Maryland statute in 1999. He, therefore, contends that he cannot be held to
    11
    account under that statute now.11 Regardless, even if the statutes could be compared,
    McCloy argues that the federal law upon which he was convicted, 
    18 U.S.C. § 1512
    (c)(1),
    does not sufficiently align with the Maryland statute (CR § 9-305) to be considered
    equivalent. Further, he maintains that because the underlying facts of his conviction would
    not support a conviction under the Maryland statute, the laws are not equivalent, and his
    conviction is therefore not a “disqualifying crime.” Lastly, McCloy asserts that even if his
    federal conviction constitutes a disqualifying crime, the circuit court erred by affirming the
    denial of his application on grounds distinct from those reached by the ALJ. For the
    reasons that follow, we are not persuaded.
    2.     When determining whether an “out-of-state” conviction is a
    “disqualifying crime,” we compare the “out-of-state” statute to an
    “equivalent” Maryland statute, utilizing Maryland laws and their
    requisite penalties as they existed at the time of the filing of the HQL
    application.
    In 2006, the Attorney General of Maryland issued an opinion advising the
    Superintendent of the MSP how convictions from other jurisdictions outside Maryland
    interact with Maryland’s firearms regulatory scheme when establishing “disqualifying
    crimes.” See generally 91 Op. Att’y Gen. 68, 68–80 (Md. 2006). Notably, as issues
    relating to the permitting process have worked their way through Maryland appellate
    courts, the core tenets of that Attorney General’s Opinion embedded in our case law on
    this issue. See McCloud v. Dep’t of St. Police, Handgun Permit Rev. Bd., 
    426 Md. 473
    ,
    11
    The enabling legislation for the Maryland statute considered equivalent to the
    federal law under which McCloy was convicted passed the General Assembly and was
    signed into law in 2002. See 2002 Md. Laws Ch. 26 (H.B. 11).
    12
    476 (2012) (“We shall hold that the [Appellate Court of Maryland] did not err in adopting
    the views expressed in the Attorney General’s Opinion to determine what constitutes a
    disqualifying crime.”).
    A “disqualifying crime” includes both offenses committed in Maryland, as well as
    those offenses committed out-of-state that would be classified as misdemeanors with a
    potential penalty of more than two years’ imprisonment under Maryland law.12 
    Id. at 476
    ;
    Brown, supra, 188 Md. App. at 480 (“The conviction for the violation can be from any
    state,” so long as the violation would classify as a misdemeanor with a penalty of more
    than two years’ imprisonment under Maryland law).
    The actual penalty in the jurisdiction where the conviction occurred is not
    controlling; instead, the MSP “must look to the maximum penalty for the equivalent
    offense in Maryland.” McCloud, supra, 426 Md. at 476; see also McLean, supra, 197 Md.
    App. at 448 (“[T]he General Assembly intended for PS § 5-101(g)(3) to be interpreted such
    that the conviction’s potential punishment is measured by reference to the penalty under
    12
    The opinion of the Attorney General of Maryland (authored by then Chief
    Counsel Opinions and Advice Robert N. McDonald), makes clear that:
    The phrase “disqualifying crime” includes out-of-State
    offenses, as well as those committed in Maryland. An offense
    in another state that would be classified as a misdemeanor in
    Maryland with a potential penalty under Maryland law in
    excess of two years[’] imprisonment falls within that
    definition. Thus, an individual who has been convicted of such
    an offense may not possess a regulated firearm in Maryland.
    91 Opp. Att’y at 68.
    13
    the law of Maryland for a comparable violation.”). Although the conviction at issue in
    McCloud was a violation of the District of Columbia’s criminal code -- and thus akin to a
    conviction in another state -- we see no reason why McCloud’s holding would not apply to
    federal convictions later deemed “disqualifying crimes” as well.13 See McCloud, 
    supra,
    426 Md. at 476.
    Further, in evaluating whether an out-of-state conviction constitutes a
    “disqualifying crime,” we look to the Maryland law, and its respective maximum statutory
    penalty, “at the time of the application for a permit or renewal application to carry or
    otherwise possess a regulated firearm.” McLean, supra, 197 Md. App. at 433; see also 91
    Op. Att’y at 68 (reasoning that because the gun permit statutes regulate the current
    possession of firearms, “the determination as to whether a particular misdemeanor ‘carries’
    a penalty in excess of two years should be made with reference to the penalty at the time
    of possession, if it is different from the potential penalty at the time of conviction”
    (emphasis added)).
    13
    In McCloud, the Supreme Court of Maryland (at the time named the Court of
    Appeals of Maryland) observed that:
    If the Legislature had not intended out-of-state misdemeanors
    to be included, then it would have simply excluded the words
    “a violation classified as,” and said, “a misdemeanor in the
    State that carries a statutory penalty of more than [two] years.”
    The words “violation classified as a misdemeanor in the State”
    add out-of-state crimes to the statute’s purview if they are
    equivalent to a Maryland misdemeanor carrying such penalty.
    426 Md. at 480.
    14
    Looking to Maryland criminal statutes and their requisite penalties at the time an
    applicant requests a gun permit “promotes consistency and equality in the treatment of all
    persons convicted of the same criminal conduct[,] regardless of where or when the criminal
    conduct occurred.” McLean, supra, 197 Md. App. at 449. Even if an out-of-state
    conviction would not disqualify lawful gun ownership in the jurisdiction where it occurred,
    the conviction could nonetheless constitute a “disqualifying crime,” preventing the
    applicant from obtaining a firearm permit in Maryland. See Brown, supra, 188 Md. App.
    at 484 (“We hold that federal law does not preempt Maryland from adopting and applying
    its own law to determine the effect of out-of-state convictions under this State’s criminal
    disarmament laws.”).
    Accordingly, McCloy’s out-of-state conviction disqualifies him from obtaining a
    gun permit in Maryland, even if the conviction neither carried a penalty of more than two
    years’ imprisonment, nor precluded the ability to obtain a firearm permit in the jurisdiction
    where the conviction was rendered. McCloud, supra, 426 Md. at 476; Brown, supra, 188
    Md. App. at 484. Further, McCloy’s argument that his 1999 conviction cannot be
    compared to CR § 9-305(a), or to § 9-306, because those statutes were not in existence in
    1999 is equally unavailing.14 In short, it is irrelevant what the laws of Maryland were at
    the time of his conviction; what matters is that the statute deemed comparable to the out-
    14
    The General Assembly enacted PS § 9-305 as part of House Bill 11 during the
    2002 Legislative Session, amending it in 2005 and again in 2018. See 2002 Md. Laws Ch.
    26 (H.B. 11); 2005 Md. Laws Ch. 461 (S.B. 122); 2018 Md. Laws Ch. 145 (S.B. 1137)
    (amending the maximum penalty under the statute from 20 years’ imprisonment to 10).
    The General Assembly enacted PS § 9-306 through House Bill 11 during the 2002
    Legislative Session, as well. See 2002 Md. Laws Ch. 26 (H.B. 11).
    15
    of-state conviction was in place at the time he submitted his HQL application. McLean,
    supra, 197 Md. App. at 433.
    No entity tasked with assessing whether McCloy’s conviction was a “disqualifying
    crime” -- not the MSP, the ALJ, nor the circuit court -- erred by considering a potentially
    comparable Maryland law that was in effect at the time McCloy sought his HQL in 2021
    rather than an equivalent Maryland statute in effect at the time of his 1999 conviction.
    Critically, CR § 9-305 is classified as a misdemeanor with a potential maximum penalty of
    ten years’ imprisonment. Therefore, our review of whether the MSP erred in denying
    McCloy’s permit depends upon whether the statute under which McCloy was convicted
    (
    18 U.S.C. § 1512
    (c)(1)) can be characterized as equivalent to CR § 9-305(a), thereby
    qualifying the conviction as a “disqualifying crime.”
    3.     If the elements of both the statute underlying the out-of-state
    conviction and the comparable Maryland statute sufficiently align,
    and if a reasonable mind could agree that the statutes are equivalent
    and that the applicant’s conduct that constituted the out-of-state
    conviction could be understood to be criminalized under the
    equivalent Maryland statute, then the out-of-state conviction is a
    disqualifying crime that bars the possession of a regulated firearm.
    When determining whether a foreign conviction is a “disqualifying crime” under
    Maryland’s gun permitting laws, neither this Court nor the Supreme Court of Maryland
    have articulated a clear standard of review for assessing the determination of equivalency
    of another jurisdiction’s statute compared to a corresponding Maryland misdemeanor
    statute with a penalty in excess of two years’ imprisonment.
    McCloy advocates that we use the same standard Maryland courts use to assess the
    equivalency of convictions when determining “crimes of violence” for the purpose of
    16
    mandatory sentencing under CR § 14-101. See Hall v. State, 
    69 Md. App. 37
    , 61–62 (1986)
    (describing the two-step process, in which the court initially determines if the Maryland
    counterpart to the foreign crime would be classified as a “crime of violence” in Maryland,
    and, if so, whether the elements of the crime in the foreign jurisdiction “are sufficiently
    limited to those elements by which the crime is established in [Maryland]”). McCloy
    claims this method is consistent with the “categorical approach” used by federal courts
    when applying the Armed Career Criminal Act. See Taylor v. United States, 
    495 U.S. 575
    ,
    600–02 (1990). In addressing this element-by-element comparison, McCloy points to
    inconsistencies between the statutes that he alleges undermine the MSP’s conclusion that
    they are equivalent.
    The MSP appears to adopt this element-by-element comparison of the statutes as
    well, but it focuses on the common purpose of statutes -- that both prevent the intentional
    interference with or impeding of another person’s participation in a court proceeding -- as
    controlling. The circuit court compared the elements of the respective statutes and
    ultimately determined that sufficient commonalities existed, specifically the common
    element of intent to disrupt a judicial proceeding. The MSP maintains that this Court
    should affirm the determination of equivalency.
    The paucity of applicable case law provides us with no explicit standards on how to
    review this equivalency determination. We start our analysis by looking at this Court’s
    decision in Brown for guidance. In Brown, we reviewed whether the MSP’s conclusion
    that Brown’s District of Columbia (“D.C.”) conviction for possession of a prohibited
    weapon (a pipe) under 
    D.C. Code § 22-3214
     (1981) was equivalent to Maryland’s CR § 4-
    17
    101(c)(2) (2003), “which forbids wearing or carrying a dangerous weapon with intent to
    injure.” 188 Md. App. at 464–65. Thereafter, we held that “we need not decide whether
    the evidence before [the MSP] would have been sufficient to support a conviction for a
    criminal offense that was predicated upon a prior conviction for a disqualifying crime.” Id.
    at 487.
    Instead, we observed that we must determine “whether there is substantial evidence
    to support the [MSP’s] determination that the act Brown was convicted of committing in
    D.C. would constitute the Maryland offense of wearing or carrying a dangerous weapon.”
    Id. at 486–87. We concluded that Brown’s conviction in D.C. would constitute an offense
    under the comparable Maryland statute. Id. at 487. We recognized that there were
    distinctions between the Maryland and D.C. statutes, including the former requiring intent
    to injure, whereas the latter had no such intent requirement.               Id. at 487–88.
    Notwithstanding these distinctions, because Brown admitted in his plea in the Superior
    Court of D.C. that he possessed a deadly weapon, the pipe, and that he “[g]ot into an
    altercation with another male,” we held that “substantial evidence” existed for the Board
    to determine that Brown had been convicted of an equivalent crime.15 Since the “D.C.
    conviction for possession of a dangerous weapon would be equivalent to the Maryland
    15
    Because the Maryland statute required an intent to injure, but the D.C. statute did
    not, this Court reasoned that since Brown admitted to both having a weapon and to getting
    into an altercation, circumstantial evidence existed to show, or at least to infer, that Brown
    intended to use the pipe to injure the other male with whom he had an altercation. See
    Brown, supra, 188 Md. App. at 488.
    18
    conviction for wearing or carrying a dangerous weapon,” Brown’s out-of-state conviction
    constituted a disqualifying crime that prohibited him from obtaining an HQL. Id. at 488.
    Accordingly, though this Court in Brown acknowledged that the determination of
    whether the D.C. conviction constituted a “disqualifying crime” was a question of law, this
    Court, in making its legal determination, relied upon the facts from Brown’s conviction to
    assess whether the relevant Maryland statute was equivalent. See id. at 446–48. While the
    underlying question of law was reviewed de novo, this Court in Brown held that the
    utilization of additional facts lent itself to the “substantial evidence” test.16 Id. at 446–47
    (“When we review an agency decision that is a mixed question of law and fact, we apply
    the substantial evidence test,” as we would for a purely factual determination.).
    We, therefore, hold that the analysis provided by Brown applies in the following
    manner when assessing the determinations made by the MSP of the equivalency of out-of-
    state convictions against comparable misdemeanors in Maryland. Initially, we compare
    the statutory elements of the applicant’s out-of-state conviction with the elements of the
    comparable Maryland misdemeanor with a penalty in excess of two years’ imprisonment,
    16
    Applying the “substantial evidence” test in this fashion also aligns with the less
    stringent “preponderance of evidence” standard used in hearings conducted by the OAH
    regarding such appeals of HQL application denials, rather than the far more onerous
    “reasonable doubt” standard of a criminal proceeding. See Md. Code, (1984, 2021 Repl.)
    § 10-217 of the State Government Article (“SG”); Md. Code Regs. (“COMAR”)
    29.03.01.22(D), (H). It also aligns with the “preponderance of evidence” standard utilized
    in civil matters. See Santosky v. Kramer, 
    455 U.S. 745
    , 755 (1982) (discussing the different
    stakes involved in civil, compared to criminal, disputes resulting in the former using the
    “‘preponderance of the evidence’ standard” compared to the latter using the “‘reasonable
    doubt’ standard”). Though McCloy’s conviction was a criminal matter, the application of
    that conviction within the firearms regulatory scheme is “civil in character.” State v.
    Raines, 
    383 Md. 1
    , 31–32 (2004).
    19
    noting that we look to both the applicable Maryland law and the maximum penalties
    corresponding with that respective law at the time of the application, not at the time of the
    applicant’s out-of-state conviction. See McCloud, 
    supra,
     426 Md. at 476, McLean, supra,
    197 Md. App. at 433, Brown, supra, 188 Md. App. at 480.
    If we conclude that the statutes are comparable, we then assess whether a reasonable
    mind could conclude that the out-of-state and Maryland statutes prohibit similar conduct,
    based upon a comparison of the elements of the respective statutes. See Brown, supra, 188
    Md. App. at 467; see also Proven Mgmt., Inc., supra, 
    472 Md. at 667
     (noting that under
    the “substantial evidence test” we affirm the agency’s decision if we find “such relevant
    evidence as a reasonable mind might accept as adequate to support [the agency’s]
    conclusion.” (citation omitted)). In that context, we determine if a reasonable mind, in the
    position of the authority determining whether the out-of-state conviction is a disqualifying
    crime, could conclude that the conduct producing the applicant’s out-of-state conviction
    could be considered prohibited by the purportedly “equivalent” Maryland statute. See
    Brown, supra, 188 Md. App. at 467; see also Proven Mgmt., Inc., supra, 
    472 Md. at 667
    .
    If we answer both these inquiries in the affirmative, then the determination that the out-of-
    state conviction is a “disqualifying crime” should be affirmed.17 We turn now to applying
    17
    Although this standard we extract from Brown may not be as exacting as the
    element-by-element approach McCloy demands, it aligns with the “categorical approach”
    he asserts the MSP should adopt. The “categorical approach,” used by federal courts when
    applying the Armed Career Criminal Act, looks to compare statutes with “certain common
    characteristics . . . regardless of how they were labeled by state law,” thus it has the
    potential to “permit the [reviewing court] to go beyond the mere fact[s] of [the]
    conviction.” Taylor, 
    supra,
     
    495 U.S. at 589, 602
    ; see also United States v. Proctor, 28
    20
    this analytical framework to this dispute.18
    We begin by noting that CR § 9-305 satisfies the statutory requirements of a
    “disqualifying crime,” because it is a misdemeanor in Maryland that carries a penalty in
    excess of two years’ imprisonment in effect at the time McCloy filed his 2021 HQL
    application. McCloud, 
    supra,
     426 Md. at 487. Additionally, because McCloy’s conviction
    F.4th 538, 544–45 (4th Cir. 2002). This approach looks to the “minimum conduct” needed
    to commit the equivalent offense, as established by relevant state court decisions. Proctor,
    supra, 28 F.4th at 545. So long as there exists a “‘realistic probability, not [just] a
    theoretical possibility,’ that a state would actually punish that conduct,” a court can proceed
    to evaluate that minimum conduct committed by the defendant under the comparable
    Maryland law. Id. (quoting United States v. Doctor, 
    842 F.3d 306
    , 308–09 (4th Cir. 2016)).
    Similarly, the standard we set forth also aligns with the two-step analysis for “crimes
    of violence” articulated in Hall v. State -- and advocated by McCloy -- in which a court
    reviews whether the elements of the out-of-state crime providing the basis of the
    defendant’s conviction “are sufficiently limited to those elements by which the crime is
    established in [Maryland].” 69 Md. App. at 61–62.
    18
    Notably, the issue of determining whether an out-of-state conviction is a
    disqualifying crime under PS § 5-101(g)(3) is a matter of statutory interpretation, and thus
    a question of law we review de novo. See McLean, supra, 197 Md. App. at 438. As such,
    we analyze whether CR § 9-305(a) is equivalent to 18 U.S.C. 1512(c)(1), as this was the
    determination made by the MSP and reviewed by the ALJ.
    Additionally, the ALJ’s analysis of CR § 9-306(a) (“A person may not, by threat,
    force, or corrupt means, obstruct, impede, or try to obstruct or impede the administration
    of justice in a court of the State.”), which she determined was the more appropriate match
    to McCloy’s federal conviction than CR § 9-305(a), was not argued before her but
    addressed by the ALJ sua sponte. This raises significant due process concerns discussed
    infra. Thus, because our de novo review puts us effectively in the shoes of the ALJ, we
    will limit our review to the arguments made by the parties before the ALJ. See Brown,
    supra, 188 Md. App. at 466–67 (stating we review the agency decision de novo); Regan,
    
    supra,
     120 Md. App. at 511 (stating a reviewing court may substitute its judgment for that
    of the agency when that court finds error while reviewing a matter of law). As such, we
    need not address the potential equivalency of CR § 9-306 with McCloy’s conviction.
    21
    occurred in 1999, our equivalency evaluation will utilize the version of the federal statute
    from that year.
    Broken into its component parts, 
    18 U.S.C. § 1512
    (c)(1), as read in 1999 when
    McCloy was convicted, prohibits (i) the intentional (ii) harassment (iii) of another person,
    (iv) which results in hindering, delaying, preventing, or dissuading that person (v) from
    attending or testifying (vi) in an official proceeding.19 The definition of an “official
    proceeding,” most pertinent to both this comparison and to the facts of McCloy’s
    conviction, is “a proceeding before a judge or court of the United States, a United States
    magistrate judge . . . or . . . before a Federal Government agency which is authorized by
    law.” 
    18 U.S.C. § 1515
    (a)(1)(A), (D). Section 9-305(a) of the Maryland Criminal Law
    Article prohibits a person from (i) threatening, forcing, or using “corrupt means” (ii) to
    attempt to influence, intimidate or impede (iii) a juror, a witness, or an officer of a court of
    Maryland or the United States, (iv) in the performance of that individual’s official duties.20
    In our view, there are several comparable components between these statutes. Most
    notably, both statutes prevent intentionally attempting to thwart another person’s
    participation in a judicial or a quasi-judicial proceeding. While 
    18 U.S.C. § 1512
    (c)(1)
    requires the defendant to “intentionally” attempt to hinder or prevent a person from
    19
    The statute specifically addresses one who “intentionally harasses another person
    and thereby hinders, delays, prevents, or dissuades any person from attending or testifying
    in an official proceeding.” 
    18 U.S.C. § 1521
    (c)(1) (1999).
    20
    “A person may not, by threat, force, or corrupt means, try to influence, intimidate,
    or impede a juror, a witness, or an officer of the court of the State or of the United States
    in the performance of the person’s official duties.” CR § 9-305(a). The elements of the
    statute have not changed since McCloy submitted his application in 2021.
    22
    testifying, CR § 9-305(a) prohibits a defendant from attempting to impede a witness from
    performing her duties -- which, when applied to McCloy’s conviction, can only logically
    mean the witness’ duty to testify -- by using “corrupt means.” Such “corrupt means
    involves acting with corrupt intent,” including what may seem otherwise benevolent or
    lawful actions but done with the intent “to preclude another person from testifying.”
    State v. Wilson, 
    471 Md. 136
    , 168 (2020) (holding that the defendant used “corrupt means”
    under CR § 9-305(a) by lawfully marrying a witness with the intent to preclude that witness
    from testifying in a criminal proceeding due to marital privilege).
    We next proceed to our second analytical step, in which we view whether a
    reasonable mind could conclude that the conduct resulting in McCloy’s conviction under
    
    18 U.S.C. § 1512
    (c)(1) would also be prohibited by CR § 9-305(a). McCloy’s attempt to
    reach a monetary resolution with his co-worker, the complainant in the EEOC case, for the
    purpose of dissuading her from participating in the adjudication of that proceeding satisfies
    this definition of “corrupt means” articulated in Wilson. Indeed, McCloy attempted to
    settle the sexual harassment dispute with his co-worker by offering her $1,000 for her to
    dismiss the EEOC complaint. Monetary settlements are common, lawful methods of
    resolving disputes. Nevertheless, while McCloy’s actions may appear to be legal in
    isolation, they would be illegal if done with the “corrupt intent” of preventing the witness
    from testifying in an official proceeding. Id.
    The same characterization applies to McCloy’s efforts to have his co-worker not
    disclose the phone call the co-worker overheard. Id. Notably, the “official proceeding”
    element of § 1512(c)(1) encompasses proceedings by federal agencies, like one resulting
    23
    from an investigation of a complaint by the EEOC. 
    18 U.S.C. § 1515
    (a)(1)(A), (D). Such
    a proceeding would occur in a “court of the United States” -- whether it be an Article I
    federal agency court or an Article III federal district court -- where the witness would
    perform her “official duties” of testifying, as required under CR § 9-305(a).
    Therefore, a reasonable mind could reach the determination made by the MSP that
    
    18 U.S.C. § 1512
    (c)(1) and CR § 9-305(a) are equivalent such that substantial evidence
    exists to support the conclusion that McCloy had been convicted of a “disqualifying crime”
    that precluded him from obtaining a handgun permit. See Brown, supra, 188 Md. App. at
    488. We, therefore, agree with the ultimate determination of the ALJ that the MSP did not
    err in denying McCloy’s application to purchase a regulated firearm.
    4.     The circuit court did not err in modifying the ALJ’s ruling while affirming
    the denial of McCloy’s HQL application.
    We affirm the circuit court’s determination that the MSP correctly denied McCloy’s
    HQL application. Nonetheless, the circuit court acknowledged that the ALJ exceeded her
    authority by considering, and then concluding, that McCloy’s federal conviction was
    equivalent to CR § 9-306 rather than CR § 9-305(a), as argued by the MSP. McCloy Cir.
    Ct. Rev., supra, at 7. The circuit court further agreed with McCloy that the ALJ erred in
    finding that McCloy provided a false statement on his HQL application regarding his
    federal conviction constituting a disqualifying crime.21 Id.
    21
    The ALJ concluded, on grounds other than those argued before it, that the MSP
    properly denied McCloy’s permit application. We disagree with the reasoning of the ALJ.
    Our equivalency analysis supra demonstrates that it was not reasonable for McCloy to
    know that he was making such a false statement, as his federal conviction did not carry
    24
    The circuit court was not bound by the ALJ’s legal conclusions because -- while
    mindful of the deference owed to an agency’s “longstanding” interpretation premised upon
    the agency’s “area of expertise” -- the determination of statutory equivalence is a question
    of law reviewed de novo. McLean, 197 Md. App. at 438. Because the MSP, and not the
    ALJ, is the agency tasked with reviewing HQL applications and interpreting “disqualifying
    crime[s]” under PS § 5-101(g), such deference may be owed to the MSP, but not to the
    ALJ, in the circuit court’s de novo review. Id.; see Brown, supra, 188 Md. App. at 471
    (stating the MSP is charged with interpreting relevant law in approving or denying HQL
    applications); see also PS § 5-121(a) (authorizing the MSP to review HQL applications).
    Thus, the circuit court was free to independently review the MSP’s assertion that 
    18 U.S.C. § 1521
    (c)(1) was equivalent to CR § 9-305(a), and, in so doing, determine that McCloy’s
    conviction was a disqualifying crime.
    Further, when reviewing a decision by an administrative agency, the circuit court
    may remand for further proceedings, affirm or reverse the final decision of the agency, or
    “modify the decision if any substantial right of the petitioner may have been prejudiced.”
    Md. Code, (1984, 2021 Repl.) § 10-222(h) of the State Government Article (“SG”). Here,
    such a two-year penalty, and, as we have shown, the equivalency analysis was not
    straightforward, as even the ALJ misconstrued it. See PS § 5-139(a) (prohibiting a person
    from knowingly making a false statement on a firearm application). The MSP issuing
    McCloy his 2015 HQL, despite knowing of his 1999 conviction, underscores this
    confusion. McCloy cannot be charged with knowledge that his 1999 conviction was a
    “disqualifying crime” when he submitted his 2021 HQL application because even the MSP
    did not make such a determination until after this request. Moreover, the ALJ reached this
    conclusion sua sponte, without it being asserted by the MSP, and without providing
    McCloy reasonable grounds to present a defense to such a claim at a hearing, thus raising
    due process concerns.
    25
    the circuit court determined that the ALJ violated McCloy’s rights by considering
    arguments not presented at the hearing. See McCloy Cir. Ct. Rev., supra, at 7. The circuit
    court further determined that the ALJ unreasonably concluded that McCloy should have
    known his 1999 federal conviction was disqualifying despite the prior issuance of his 2015
    HQL. Id. As such, the circuit court correctly modified the ALJ’s decision. Critically, this
    did not alter the circuit court’s, nor the ALJ’s, ultimate conclusion that the MSP properly
    denied the permit. Because we agree with this conclusion as well, we affirm the circuit
    court’s order affirming the denial of McCloy’s HQL application.
    B.     McCloy is not entitled to equitable relief from the denial of his HQL
    application.
    McCloy asserts that even if the MSP correctly applied the law explained supra and
    determined that his 1999 conviction prohibits the approval of his 2021 HQL application,
    numerous equitable principles bar the MSP from denying him his right to gun ownership.
    These principles do not warrant the outcome advanced by McCloy, particularly in this
    context.
    1.     The MSP’s prior approval of McCloy’s 2015 HQL license does not
    estop the agency from denying his 2021 HQL application.
    McCloy argues that the MSP’s previous issuance of his 2015 HQL, despite the
    existence of his 1999 conviction, estops the agency, and by extension the ALJ and this
    Court, from denying his 2021 HQL application. Further, because McCloy used this license
    to then purchase regulated firearms, he claims the denial of his 2021 license is akin to
    entrapment. We find little reason to wade into this argument because the issuance or denial
    of an HQL is not a criminal matter warranting the affirmative defense of entrapment-by-
    26
    estoppel.22 McLean, supra, 197 Md. App. at 447 n.24 (refusing to address McLean’s
    entrapment by estoppel arguments because “there has been no effort on the part of MSP to
    prosecute for violation of firearms laws,” and “the statute in question is not a penal
    statute”).
    More directly, though, his estoppel argument has no merit, because the MSP cannot
    be estopped from enforcing its statutory scheme in regulating firearms. “[T]he doctrine of
    estoppel will not be applied against the State in the performance of its governmental, public
    or sovereign capacity or in the enforcement of police measures.” Salisbury Beauty Schs.
    v. St. Bd. of Cosmetologists, 
    268 Md. 32
    , 63–64 (1973). To estop the State from enforcing
    otherwise valid laws or regulations because prior conduct of public employees led the
    claimant to believe the law was otherwise would deprive the public of the protections
    provided by the statute only because of the mistaken action of those employees. In re
    Cash-N-Go, Inc., 
    256 Md. App. 182
    , 206 (2022). The fact that the MSP approved prior
    firearms purchases does not preclude the agency from correctly applying the statute now
    and determining McCloy’s 1999 conviction is a disqualifying crime that bars the issuance
    of his handgun permit. See McLean, supra, 197 Md. App. at 446–47, 449.
    22
    Any potential criminal consequences from the denial of McCloy’s HQL
    application are not before us. See McLean, supra, 197 Md. App. at 447 (“[T]here is no
    reason to believe that [McLean] would not be given reasonable consideration for the
    transfer of any regulated firearms in his possession before being subject to any criminal
    liability.”).
    27
    2.     The Ex Post Facto Clause does not bar the MSP from determining that
    McCloy’s 1999 federal conviction was a “disqualifying crime.”
    McCloy asserts that applying the penalties of a Maryland criminal statute that did
    not exist at the time the conduct resulting in his 1999 federal conviction occurred violates
    both the United States and Maryland constitutional provisions against retrospective
    punishment, commonly referred to as “ex post facto laws.” See U.S. Const. art. 1 § 10, cl.
    1; Md. Const. art. 17; Watkins v. Sec’y, Dep’t of Pub. Safety & Corr. Servs., 
    377 Md. 34
    ,
    48 (2003) (“Maryland’s ex post facto clause has been viewed generally to have the ‘same
    meaning’ as its federal counterpart.”). We disagree. Indeed, the prohibition of ex post facto
    laws concerns the punishing of acts presently deemed criminal when they were not viewed
    as such at the time of their occurrence. Watkins, supra, 
    377 Md. at 48
    .
    Most obviously, the statutes regulating firearms apply to their current possession
    and transfer, not to past behaviors. See 91 Opp. Att’y at 79; see also Corcoran v. Sessions,
    
    261 F. Supp. 3d 579
    , 601–02 (D. Md. 2017) (“The Maryland Firearms Prohibitions under
    challenge here are not retrospective. . . . For the same reason that firearms prohibitions do
    not run afoul of the Ex Post Facto Clause when used to prosecute a new offense, they do
    not offend the Clause when as-applied to prohibit a person from possessing a firearm in
    the first place.”). The determination that McCloy’s 1999 conviction under 
    18 U.S.C. § 1512
    (c)(1) is equivalent to CR § 9-305(a) -- a statute that did not exist at the time of his
    conviction -- does not further criminalize or punish McCloy, nor does it modify his
    conviction in any way. See State v. Raines, 
    383 Md. 1
    , 30 (2004) (holding Maryland statute
    permitting the DNA collection of persons whose commission of a qualifying crime
    28
    occurred prior to the effective date of the statute did not violate the ex post facto clause);
    91 Opp. Att’y at 79 (“While a disqualification under the regulated firearms law can be a
    collateral consequence of a criminal conviction, it is not part of the sentence.”).
    Further, the gun licensing provisions enforced against McCloy are a “regulatory
    scheme and [are] thus civil in character.” Raines, supra, 
    383 Md. at
    31–32. “Any deterrent
    effect is secondary to the regulatory nature of the statute.” 
    Id. at 30
    . The logical extension
    of McCloy’s position would prevent the government from modifying any regulatory
    scheme for fear its new application would be deemed unconstitutionally retrospective.
    3.     McCloy’s due process claims are more appropriate for consideration
    via post-conviction relief rather than as a challenge to the denial of
    his 2021 HQL application.
    McCloy asserts two theories of how the denial of his HQL application violated his
    due process rights. First, he argues that denying him the ability to purchase a firearm
    violates his due process rights because he was not informed in 1999 that a collateral
    consequence of his guilty plea would mean the subsequent stripping of his constitutional
    right to keep and bear arms. Initially, we note the logical impossibility at the root of
    McCloy’s assertion. He essentially argues that prior to the acceptance of his 1999 guilty
    plea, he should have been informed that his conviction might be considered equivalent to
    a statute not yet in existence, and that 20 years after his conviction, this equivalency
    determination would prohibit him from obtaining a gun permit. Regardless, “[e]ven if it
    was constitutionally required for [McCloy] to be informed of this collateral consequence,
    the proper remedy for such a violation of his due process rights would be to attack his
    guilty plea in [United States District Court for the District of Columbia] as involuntary,”
    29
    or to pursue a claim of ineffective assistance of counsel, or other postconviction relief, in
    the court that accepted his plea and conviction. McCloud v. Dep’t of St. Police, 
    200 Md. App. 725
    , 734 (2011), aff’d sub nom. McCloud v. Dep’t of St. Police, Handgun Permit Rev.
    Bd., 
    426 Md. 473
     (2012).
    McCloy also maintains that a due process violation occurred following his OAH
    hearing because the ALJ made the sua sponte determination that 
    18 U.S.C. § 1512
    (c)(1)
    was not equivalent to CR § 9-305(a) but rather to CR § 9-306. He alleges that this deprived
    him of the ability to participate in a full and fair hearing in which he could prepare to rebut
    the arguments against him.23 Though we are troubled by the ALJ’s decision to pursue
    reasoning for the denial of the permit beyond the arguments presented by the MSP, we
    review the ALJ’s legal conclusion de novo. As a result, we return McCloy to the same
    position he was in before the ALJ because we considered only arguments regarding
    whether CR § 9-305(a) -- not CR §§ 9-306 or 9-302 -- was the appropriate Maryland law
    to compare to McCloy’s federal conviction. Accordingly, we affirm the MSP’s denial of
    McCloy’s application, supra, on other grounds as explained within this opinion.
    23
    Related to this due process argument is McCloy’s frustration with the MSP,
    which originally informed him that the agency determined his 1999 conviction was
    equivalent to a conviction under CR § 9-302, only to change that determination shortly
    before the OAH hearing and instead say that the equivalent Maryland statute was CR § 9-
    305(a). Notably, at the OAH hearing, McCloy’s counsel failed to object to this notice.
    Further, though not dispositive, at the hearing McCloy’s counsel argued that (1) McCloy
    could not now be held to account under a statute that did not exist at the time of his
    conviction, and that (2) the facts underlying McCloy’s federal conviction would not result
    in a conviction under Maryland law.
    30
    At oral argument, the parties addressed the legality of McCloy’s possession of
    firearms lawfully purchased with his 2015 HQL. Initially, we note that the ensuing
    repercussions of our affirmance in this case, and the potential consequence this may have
    on his possession of those firearms, is not before us. See Diallo v. State, 
    413 Md. 678
    ,
    692–93 (2010) (“[A]rguments not presented in a brief or not presented with particularity
    will not be considered on appeal.” (citation omitted)). Additionally, as this court has
    addressed such a concern in prior cases interpreting “disqualifying crime” determinations:
    We recognize that interpreting PS § 5-101(g)(3) as we do may
    seem harsh in this particular situation—as it results in the non-
    renewal of [McLean’s] permit to carry a handgun, where there
    is no indication that he has abused the right provided to him by
    that permit, or for that matter, any firearms permit, in any
    way. . . . But, in light of the overall statutory scheme, that does
    not necessarily render the interpretation illogical, unreasonable
    or inconsistent with common sense, as urged by [McLean].
    ...
    Nothing in the record reflects an effort by MSP to void any
    existing permits and, even if that were the case, there is no
    reason to believe that [McLean] would not be given reasonable
    consideration for the transfer of any regulated firearms in his
    possession before being subject to any criminal liability.
    McLean, supra, 197 Md. App. at 445–47.
    CONCLUSION
    Returning to the issue at the heart of this appeal, we synthesize the prior holdings of
    this Court and the Supreme Court of Maryland into the following standard for reviewing
    courts to utilize when analyzing the MSP’s determination that an out-of-state conviction is
    a “disqualifying crime” under Maryland’s firearms regulatory framework. First, the
    reviewing court must compare the elements of the foreign statute providing the basis for
    31
    the applicant’s out-of-state conviction with the elements of the purportedly equivalent
    Maryland misdemeanor statute with a penalty of more than two years’ imprisonment to
    determine if a reasonable mind could accept the conclusion that the foreign and Maryland
    statutes aim to prohibit the same conduct. In so doing, the reviewing court must use the
    Maryland statute (and its maximum penalty) as it existed at the time the applicant requested
    an HQL, not at the time of the applicant’s out-of-state conviction.
    Thereafter, the reviewing court must determine whether a reasonable mind could
    conclude that the conduct producing the applicant’s out-of-state conviction would be
    prohibited by the purportedly equivalent Maryland statute. If the reviewing court answers
    both these inquiries affirmatively, then the MSP’s equivalency determination must be
    affirmed, as well.
    We, therefore, agree with the MSP’s conclusion that McCloy’s 1999 federal
    conviction under 
    18 U.S.C. § 1512
    (c)(1) was equivalent to CR § 9-305(a), a misdemeanor
    in Maryland with a maximum penalty in excess of two years’ imprisonment. As such, his
    conviction is a “disqualifying crime” that prohibits him from possessing a regulated firearm
    and requires the MSP to deny his HQL application. We, therefore, agree with the ultimate
    determination of the ALJ, and because the circuit court rightfully modified the ALJ’s
    conclusions while affirming the ALJ’s judgment, we affirm the judgment of the circuit
    court.
