delivered the Opinion of the Court.
Thе heirs of Curtis Sigman (plaintiffs) appeal the district court’s dismissal of their wrongful death action based on its ruling that section 12-47-128.5, 5 C.R.S. (1990 Supp.), precluded the plaintiffs’ claims and *529 that the statute was constitutional. 1 We affirm.
I.
On July 19,1989, Curtis Sigman (Sigman) consumed an excessive amount of alcoholic beverages at a bar and restaurant in Denver, Colorado, known as Mostly Seafood. When the inebriated Sigman аttempted to leave the restaurant, he fell down a flight of stairs, incurring head injuries that resulted in his death on July 25, 1989.
In May 1990, Sigman’s heirs instituted a wrongful death action against the defendants, Seafood Limited Partnership I, the owner of Mostly Seafood, and its general partner, Seafood Enterprises, Inc. The plaintiffs asserted six causes of action basеd on negligent supervision, vicarious liability, negligence resulting in wrongful death, negligence per se, outrageous conduct, and entitlement to exemplary damages. The defendants filed a motion to dismiss the plaintiffs’ complaint for failure to state a claim upon which relief can be granted pursuant to C.R.C.P. 12(b)(5), arguing that section 12-47-128.5(3)(b) barred the рlaintiffs’ claims. The district court granted the defendants’ motion, concluding that the statute precluded the plaintiffs’ claims and that, contrary to the plaintiffs’ contention, the statute was constitutional.
II.
The plaintiffs argue that section 12-47-128.5 does not preclude their wrongful death action against the defendants. We disagree.
At common law, no rеmedy was provided against one who furnished alcoholic beverages to a person who became inebriated and consequently injured himself or another.
See Lyons v. Nasby,
With the passage of section 12-47-128.5 on May 3, 1986, the liability of vendors of alcoholic beverages and social hosts became strictly a creaturе of statute.
Charlton v. Kimata,
Section 12-47-128.5 provides in relevant part:
(1) The general assembly hereby finds, determines, and declares that this section shall be interpreted so that any common law cause of action against a vendor of alcoholic beverages is abolished and that *530 in certain cases the consumption of alcoholic beverages rather than the sale, service, or provision thereof is the proximate cause of injuries or damages inflicted upon another by an intoxicated person except as otherwise provided in this section.
[[Image here]]
(3)(a) No licensee is civilly liable to аny injured individual or his estate for any injury to such individual or damage to any property suffered because of the intoxication of any person due to the sale or service of any alcoholic beverage to such person, except when:'
(I) It is proven that the licensee willfully and knowingly sold or served any malt, vinous, or spirituous liquor tо such person who was under the age of twenty-one years or who was visibly intoxicated; and
(II) The civil action is commenced within one year after such sale or service.
(b) No civil action may be brought pursuant to this subsection (3) by the person to whom the alcoholic beverage was sold or served or by his estate, legal guardian, or dependent.
(c) In any civil action brought pursuant to this subsection (3), the total liability in any such action shall not exceed one hundred fifty thousand dollars.
In construing a statute, we must ascertain and effectuate the intent of the General Assembly.
E.g., In the Interest of R.C.,
The plain language of section 12-47-128.5(1) provides that all common law causes of action against vendors of alcoholic beverages are abolished, thereby making dramshop liability strictly a creature of statute in Colorado.
See Lyons,
The civil action before us is a wrongful death action brought by Sigman’s heirs. The wrongful death statute, § 13-21-202, 6A C.R.S. (1987), provides:
When the death of a person is caused by a wrongful act, neglect, or default of anоther, and the act, neglect, or default is such as would, if death had not ensued, have entitled the party injured to maintain an action and recover damages in respect thereof, then, and in every such case, the person who or the corporation which would have been liable, if death had not ensued, shall be liable in an action for damages notwithstanding the death of the party injured.
Pursuant to Colorado’s wrongful death statute, the plaintiffs can maintain an action only if Sigman could have done so had his injuries not been fatal.
See Lyons,
By abolishing first-party claims against vendors of alcoholic beverages, the legislature has adopted the common law theory that the consumption of alcoholic beverages, rather than the sale or service thereof, is the proximate cause of the inebriate’s injuries. See § 12-47-128.5(1). It is therefore the General Assеmbly’s intent that imbibers of alcoholic beverages be responsible for whatever personal injuries they may suffer as a result of their intoxication. To allow the plaintiffs to pursue their wrongful death action against the defendants in the present case would undermine the legislature’s aim of denying compensation where an individual’s injury resulted frоm his own intoxication. We therefore hold that the statutes preclude the plaintiffs from bringing their wrongful death action. 3
III.
We next address the plaintiffs’ contention that section 12-47-128.5 is unconstitutional. The plaintiffs argue that the language in section 12-47-128.5 is so vague as to violate due process and that the statute violates the constitutional guarantеe of equal protection of the laws, U.S. Const. amend. XIV and Colo.Const. art. II, § 25, the constitutional prohibition against special legislation, Colo.Const. art. V, § 25, and the constitutional right of access to the courts, Colo.Const. art. II, § 6. At the outset, we note that a statute is presumed to be constitutional, and the party challenging the statute must prove its unconstitutionality beyond a reasonable doubt.
Palmer v. A.H. Robins Co.,
A.
The plaintiffs contend that section 12-47-128.5(l)’s provision that “in certain cases the consumption of alcoholic beverages rather than the sale, service, or provision thereof is the proximate cause of injuries or damages inflicted upon another by an intoxicated person” is unconstitutionally vague so as to violate due process of law. The plaintiffs argue that this clause is vague because it fails to specify the “certain cases” in which the consumption of alcoholic beverages, rather than the sale, service, or provision thereof, is the proximate cause of injuries sustained. We disagree.
While due process of law requires that statutes be understandable,
Earl & Sons Tire Center v. City of Boulder,
The “certain cases” language in subsection (1) does not render section 12-47-128.5 unconstitutionally vague because the term is sufficiently defined in subsections (3)(a) and (4)(a) of the statute. Subsection (1) is a preliminary statement enunciating the legislature’s intent to make dramshop liability strictly a creature of statute and to shift the responsibility for drinking alcoholiс beverages from the vendor or provider of alcoholic beverages to the consumer, with certain exceptions.
Under subsection (3)(a)(I), the sale or service of alcoholic beverages by a vendor
*532
may be the proximate cause of injuries inflicted on a third party by an intoxicated patron if the vendor “willfully and knowingly” sold or served any liquor to a minor or to a patron “who was visibly intoxicated.” Under subsection (4)(a)(I), the provision of alcoholic beverages by a social host may be the proximate cause of injuries inflicted on someone by an intoxicated minor guest if the social host “willfully and knowingly” served liquor to the minor.
See Charlton v. Kimata,
B.
We next address the plaintiffs’ contention that section 12-47-128.5 violates their constitutional right to equal protection of the laws. U.S. Const, amend. XIV; Colo. Const, art. II, § 25.
The fourteenth amendment to the United States Constitution declares that no state shall deny any person equal protection of the laws. The right to equal protection is guaranteed by the due procеss clause in the Colorado Constitution, article II, section 25.
Lujan v. Colorado State Bd. of Educ.,
Here, the plaintiffs allege that section 12-47-128.5 discriminates against first-party claimants in dramshop liability actions by depriving them of any civil claim against vendors of alcoholic beverages. In Charlton, we held that section 12-47-128.-5(4) did not violate equal protection guarantees by depriving those injured by adult guests of any civil сlaim against social hosts who served alcoholic beverages. In so holding, we stated:
When the legislature enacted section 12-47-128.5, it adopted the common law rule that the consumption of alcohol is the proximate cause of any resulting injuries. Although in Largo Corp. v. Crespin,727 P.2d 1098 , and Lyons v. Nasby,770 P.2d 1250 , we departed from the common-law rule in the context of an alcоhol vendor’s sale of alcohol, we recognized that upon the enactment of section 12-47-128.5, a plaintiff's exclusive remedy for the negligent provision of alcohol by vendors or social hosts would come from section 12-47-128.5. In subsection (1) of this statute, the legislature provides that “in certain cases the consumption of alcoholic beverages rather than the sale, service, or provision thereof is the proximate cause of the injuries or damages inflicted upon another by an intoxicated person except as otherwise provided in this section.” § 12-47-128.-5(1) (emphasis supplied). By stating that the “proximate cause” of the injuries or damages is the consumption of the alcoholic beverages by the person who later acts negligently, the legislature assigned the legal responsibility for those acts to that person even though other causes, i.e., the provision of alcohol, led to the result.
Charlton, at 951 (citation omitted). We further noted that the legislative rationale for making consumption of alcоholic beverages the proximate cause of alcohol-related injuries was to make those who choose to consume alcoholic beverages responsible if their choice results in negligence. Id. at *533 951 (citing Tape Recordings of Hearings before the House Business Affairs Committee on S.B. 86, March 13, 1986, 55th General Assembly).
We find, as we did in Charlton, that placing legal responsibility on consumers of alcoholic beverages has a rational basis in fact and is rationally related to the legitimate state purpose of preventing alcohol-related negligence. 4 We therefore conclude that the plaintiffs’ right to equal protection is not violated by section 12-47-128.5.
C.
The plaintiffs further claim that abolishing first-party claims against vendors of alcoholic beverages violates article V, section 25, of the Colorado Constitution, which prohibits the General Assembly from enacting special legislation, “granting to any corporation, association or individual any special or exclusive privilege, immunity or franchise whatever.” A statute is not special legislation, however, “when it is general and uniform in its operation upon all in like situation.”
McCarty v. Goldstein,
D.
The plaintiffs’ final contention is that section 12-47-128.5 denies them access to the courts in violation of article II, section 6, of the Colorado Constitution, which provides that “[c]ourts of justice shall be open to every person, and a speedy remedy afforded for every injury to person, property or character.” This court recognized in
O’Quinn v. Walt Disney Productions,
In conclusion, we find that section 12-47-128.5 is constitutional and bars the plaintiffs’ wrongful death action. Judgment is affirmed.
Notes
. We have jurisdiction over this appeal because the constitutionality of a statute is in question. See § 13-4-102(l)(b), 6A C.R.S. (1987).
. A "minor” is "any person who has not attained the age of twenty-one years.” § 2-4-401(6), IB C.R.S. (1980).
. In holding that the plaintiffs’ action is barred by the plain language of § 12-47-128.5(3)(b) and § 13-21-202, we believe the plaintiffs’ argu-merits to the contrary to be without merit and thereforе decline to address them individually.
. We note that vendors of alcoholic beverages already have a statutory duty not to sell liquor to one who is visibly intoxicated, and risk criminal penalties, in addition to civil suits by injured third parties, if that duty is breached. See §§ 12-47-128(l)(a), 12-47-130(l)(a)-(2), 5 C.R.S. (1985). In our view, by shifting responsibility to consumers of alcoholic beverages, § 12-47-128.5 establishes an additional deterrence to overindulgence, which further promotes the legislative purpose of reducing alcohol-related injuries and fatalities.
