Missouri Real Estate Commission (MREC) appeals from the Missouri Administrative Hearing Commission’s (AHC) decision holding that Kenneth Rayford was entitled to retain his real estate salesperson’s license. MREC contends that section 339.100.5, 1 which became effective in 2006, mandates the revocation of Rayford’s license, which he secured in 2003 or 2004, because of a 1970 conviction for second degree murder. We affirm.
Factual and Procedural History
On April 24, 1970, nineteen-year-old Rayford pleaded nolo contendere to second degree murder and was sentenced to thirty years in prison. While in prison, Ray-ford earned degrees in psychology and sociology. In 1988, Rayford was released from prison. In 1993, Rayford was released from parole. Rayford enrolled in real estate school and subsequently applied for a real estate salesperson’s license. *689 In his application, Rayford disclosed his prior conviction for second degree murder. In approximately 2003 or 2004, after a thorough investigation by MREC, Rayford was issued his real estate license and has never been subject to discipline.
On August 28, 2006, section 339.100.5 took effect. It provides that “a broker or salesperson’s license shall be revoked, or in the case of an applicant, shall not be issued, if the licensee or applicant has pleaded guilty to, entered a plea of nolo contendere to, or been found guilty of ... [a]ny dangerous felony as defined under section 556.061, RSMo.” 2 By its terms, section 339.100.5 applies to two categories of individuals — brokers and salespersons who are already licensed, and applicants seeking licensure.
On May 4, 2007, MREC revoked Ray-ford’s license in reliance on section 339.100.5. Rayford appealed the revocation to the AHC. On November 19, 2007, the AHC determined that section 339.100.5 did not require revocation of Rayford’s license. Specifically, the AHC construed section 339.100.5 to exclude from its coverage “a licensee who held a license on August 28, 2006, 3 but not when the criminal proceeding occurred.” Because Rayford fell within this narrow exception, the AHC concluded his license was not subject to mandatory revocation.
On December 19, 2007, MREC appealed the AHC’s decision to the trial court. On January 15, 2009, the trial court affirmed the decision of the AHC. MREC appeals.
Standard of Review
Our review of an administrative agency decision interpreting a statute is
de novo. Morton v. Brenner,
Analysis
In its sole point on appeal, MREC contends that the AHC erred in holding that section 339.100.5 does not mandate the revocation of Rayford’s license. MREC argues that the AHC improperly interpreted section 339.100.5 to exclude persons like Rayford because section 339.100.5 as written reflects a plain and clear legislative intent to subject all licensees to its terms, including licensees who pleaded to, or were found guilty of, a qualifying criminal offense prior to the statute’s effective date, regardless whether licensed at the time. MREC also contends that retroactive application of section 339.100.5 does not violate the prohibition against retrospective laws set forth in article I, section 13 of the Missouri Constitution. The AHC did not discuss this issue, as the AHC is not statutorily authorized to evaluate constitutional principles or to declare a statute invalid.
State Tax Comm’n v. Admin. Hearing Comm’n,
Retroactive Application of Section 339.100.5
Article I, section 13 of the Missouri Constitution provides “[t]hat no ex
*690
post facto law, nor law ... retrospective in its operation ... can be enacted. This area of the law makes use of the terms ex post facto, retrospective and retroactive.”
State v. Thomaston,
Thus, to determine whether retroactive application of section 339.100.5 to persons like Rayford is constitutionally permissible, we must determine if section 399.100.5 is retrospective. In other words, we must determine whether section 339.100.5
either
takes away or impairs a vested or substantial right
or
imposes a new obligation, duty, or disability with respect to a past transaction.
F.R. v. St. Charles County Sheriff's Dep’t,
(i) Vested or Substantial Right
MREC contends that Rayford has no vested or substantial right to hold a real estate salesperson’s license. We agree.
In
Fisher,
our Supreme Court noted that “a vested right ‘... must be something more than a mere expectation based upon an anticipated continuance of the existing law. It must have become a title, legal or equitable, to the present or future enjoyment of property or to the present or future enjoyment of the demand, or a legal exemption from a demand made by anoth
*691
er.’ ”
Applying these principles, we cannot conclude that a professional license of any kind represents a vested right. Though we have been unable to locate a Missouri case with facts similar to those before us involving revocation of a professional license based solely on an antecedent conviction, it has been stated in other Missouri decisions that a professional license is not a vested right, but rather a privilege.
Boston,
Other jurisdictions have similarly concluded that professional licenses and licenses to operate a business do not create a vested right.
See Dep’t of Health & Mental Hygiene v. VNA Hospice of Md.,
In short, no one who possesses a license has the right or ability to presume the license is “vested” or that the license has an “independent existence.” Rather, the license remains subject to the laws and regulations which authorized its issuance in the first place, which is the antithesis of a vested right. Those laws and regulations may impose criteria for eligibility, both initially or following licensure, may require annual or other renewals, and may impose conditions on a license’s continued viability tied to standards of conduct. A *692 license provides one the authority to provide or perform certain services, or to engage in a particular business or avocation. Obtaining a license may well create a sense of dependence, even reliance, on the license’s continued viability, so much so that its revocation, suspension, or lack of renewal may result in severe hardship to one whose livelihood has come to depend on the license. However, the importance of the license to the licensee has no bearing on whether the license is a vested or substantial right for purposes of article I, section 13 of the Missouri Constitution. The definition of “license” belies a contrary conclusion. “License” is defined as “[a] revocable permission to commit some act that would otherwise be unlawful.” Black’s Law Dictionary 931 (7th ed.1999). A revocable grant of permission is not a vested right.
We are mindful that once a license has been obtained, the licensee will generally acquire a property right sufficient to require substantive and procedural due process before the license can be impaired, suspended, or revoked.
Colyer v. State Bd. of Registration for Healing Arts,
We conclude, therefore, that section 339.100.5, does not satisfy the first disjunctive definition of a retrospective law, as a license, including a professional license, is not a vested or substantial right as envisioned by article I, section 13 of the Missouri Constitution. We must next evaluate whether section 339.100.5 impermissibly imposes a new obligation, duty, or disability with respect to a past transaction-the second disjunctive definition of a retrospective law.
(ii) New Obligation, Duty or Disability with Respect to Past Transactions
*693
Beyond repeating the oft cited definition of “retrospective,” very few Missouri cases have analyzed the second of the two articulated means by which a law can be deemed retrospective — whether the law imposes new obligations, duties, or disabilities with respect to past transactions. It could be argued that any law that has retroactive application in some manner imposes a new duty or obligation or a new disability with respect to a past transaction. However, it is settled that the prohibition against retrospective laws deriving from this prong of the definition “ ‘does not mean that no statute relating to past transactions can be constitutionally passed, but rather that none can be allowed to operate retrospectively so as to affect such past transactions to the substantial prejudice of parties interested.’”
Casey’s Mktg. Co. v. Land Clearance for Redevelopment Auth. of Independence, Mo.,
Our Supreme Court has carefully analyzed when a retroactive law should be deemed retrospective because it imposes a new duty, obligation, or disability on a past transaction. In
Doe v. Phillips,
In so concluding, the Court carefully distinguished other scenarios. The Court noted that in
Jerry-Russell Bliss v. Hazardous Waste,
Consistent with, and based on the combination of, these principles, the Supreme Court concluded that the Does could not analogize having been released from parole to the expiration of a statute of limitations, as to claim a “vested right” that no further consequence could be imposed on them by virtue of their prior convictions.
Phillips,
[T]he Does ... are complaining about application of the registration requirement to them, based solely on their pre-act criminal conduct.... [T]he application of that requirement truly is retrospective in its operation. It looks solely at their past conduct and uses that conduct not merely as a basis for future decision-making by the state, in regard to things such as the issuance of a license, or as a bar to certain future conduct by the Does, such as voting. Rather, it specifically requires the Does to fulfill a new obligation and imposes a new duty to register and to maintain and update the registration regularly based solely on their offenses prior to its enactment. This violates ... our constitutional ban on laws retrospective in operation.
Id. (emphasis added).
Most recently, in
F.R.,
the Supreme Court again struck as retrospective two laws that imposed “new obligations or duties ... giving new legal effect” to antecedent convictions.
In light of this instructive guidance from our Supreme Court, we conclude that section 339.100.5, which retroactively converts an antecedent criminal conviction into a per se basis for ineligibility to hold a real estate license, would be unconstitutionally retrospective if applied to mandate the revocation of a real estate license in force on the statute’s effective date based solely on the antecedent criminal proceeding. Section 339.100.5 looks solely at Rayford’s past plea of nolo con-tendere and uses that conduct not as a basis for future decision-making by the state but to impose a new duty on Ray-ford to relinquish an existing license and/or a new disability on Rayford of per se ineligibility to continue to hold an existing license. As in Phillips and F.R., Ray-ford is a convicted felon who has served his time and cannot be presumed to be a continuing felon or a present or future danger. Thus, section 339.100.5, which imposes a new duty, obligation, or disability on Rayford based solely on his single past criminal act is retrospective.
In reaching our conclusion we are mindful of, and emphasize, that the aforementioned litany of cases from the Supreme Court
would not
prohibit: (1) the application of section 339.100.5 to bar an
applicant
with an antecedent qualifying criminal offense from being denied a real estate license, as in such a case the past conduct is being looked at “as a basis for future decision-making by the state, in regard to things such as the issuance of a license;”
Phillips,
MREC complains that such an interpretation will result in applicants and licensees, the two classes of persons covered by section 339.100.5, being treated differently. MREC notes that a person who applies for a real estate license after the effective date of section 339.100.5 will be ineligible to obtain a license if the applicant has pleaded guilty to, or been found guilty of, one of the qualifying criminal offenses at any time prior to the application, even if the guilty determination predates the effective date of the statute. That is true. It is also constitutionally permissible, as discussed in
Doe v. Phillips,
Our decision today will apply equally to all who held real estate licenses on the effective date of section 339.100.5 and will prevent mandatory revocation of such licenses should the licensee have pleaded to, or been found guilty of, a qualifying criminal offense prior to the statute’s effective date, regardless whether the offense was committed
before
or
after
the license was obtained. In so concluding, we recognize that the AHC has, since its decision in this case, construed section 339.100.5 to require mandatory revocation of a license in place on the statute’s effective date where qualifying criminal proceedings occurred
before
section 339.100.5’s effective date but
after
the license was procured.
Engelmeyer v. Mo. Real Estate Comm’n,
No. 07-1883 RE,
The Relevance of Legislative Intent
MREC complains that interpreting section 339.100.5 as we do today is inconsistent with the legislature’s clear intent to apply section 339.100.5 retroactively, as reflected by the phrase “has pleaded guilty to, entered a plea of nolo conten-dere to, or been found guilty of” employed in the statute. MREC cites Barbi-eri and Boston, for this proposition. 10 We concede that in both cases the legislature’s use of similar past participle phrases mandated a conclusion that the legislature clearly intended the involved statute to have retroactive effect. 11 However, Boston and Barbieri did not involve vested or substantial rights, 12 or the imposition of new duties, obligations or disabilities on past transactions in a manner sufficient to constitute a retrospective law. MREC’s mistake in relying on Boston and Barbieri is in concluding that either case stands for the proposition that legislative intent can be independently dispositive of a statute’s permissible retroactive application, without regard to compliance with article I, section 13 of the Missouri Constitution.
MREC’s error is not without colorable support. We note there are oft repeated passages in many of our State’s reported decisions which have the effect of confusing what is actually a very simple concept. Some decisions have concluded that “prospective application of a statute is presumed unless the legislature demonstrates
*698
a clear intent to apply the amended statute retroactively,
or
if the statute is procedural or remedial in nature.”
Ball-Sawyers v. Blue Springs Sch. Dist.,
We conclude that reported decisions in this State, which may be read to suggest that legislative intent to apply a statute retroactively constitutes an independent exception to the presumption of prospective application of statutes, misspeak. There is no independent exception born of legislative intent to the proscription against retrospective laws found in our Missouri Constitution. Legislative intent to apply a law retroactively, no matter how clear, “cannot supercede [sic] a constitutional provision.”
Doe,
Conclusion
We conclude that section 339.100.5 cannot be applied retroactively to mandatorily revoke a real estate license held at the time the statute became effective based on a plea or finding of guilt predating the effective date of the statute as such an application would violate the ban against retrospective laws set forth in article I section 13 of the Missouri Constitution. We therefore affirm the trial court’s judgment affirming the AHC’s decision. 15
All concur.
Notes
. All statutory references are to RSMo 2000 as supplemented unless otherwise indicated.
. Murder in the second degree is listed as a dangerous felony in the current version of section 556.061. However, section 556.061 did not exist at the time of Rayford's offense. The AHC nonetheless found that Rayford’s conviction for murder in the second degree was a qualifying offense under section 339.100.5. This finding is not contested on appeal.
. Section 339.100.5's effective date.
. The Supreme Court’s definition of retrospective law is nearly identical to the definition of retrospective law found in Black’s Law Dictionary 1317-18 (6th ed.1990).
. Consolidated with State v. Raynor.
. On appeal, the Eighth Circuit concluded the subject statute, which implicated a medical license for non-compliance with certain tax laws, was prospective and not retroactive in its application, rendering unnecessary any discussion of retrospective application.
Crum v. Vincent,
. Because this opinion cites to two cases with the first name "Doe,” we will short cite this case by the second name throughout the rest of the opinion.
. Though Megan’s Law imposes registration requirements based on criminal conduct, it is intended to be regulatory in nature rather than punitive.
In re R.W.
v.
Sanders,
. A statute is presumed valid and we “ ‘resolve all doubt in favor of the act’s validity' and ‘make every reasonable intendment to sustain the constitutionality of the statute.’ ”
Cannon v. Cannon,
. Because we have concluded that section 339.100.5 as applied to Rayford is impermis-sibly retrospective, we need not reach whether the AHC properly construed section 339.100.5 to exclude Rayford from its coverage because Rayford was not a licensee at the time he plead nolo contendere to second degree murder, though we believe the AHC’s construction to be strained, and thus suspect, in light of Boston and Barbieri, herein discussed.
. In
Barbieri,
a statutory amendment defining habitual violator as anyone who "has been” adjudged guilty of a moving violation at least four times within two years, reflected, by use of the phrase "has been” a clear intent to permit reference back to moving violations which occurred before the statute's effective date.
.The right to drive an automobile is not a vested right.
Barbieri,
. This represents an example of the confusion that results from misuse and improper interchanging of the terms "retroactive” and “retrospective.”
. See note 12.
