OPINION
This is an appeal from a summary judgment. We will affirm the judgment.
The summary judgment record reflects that on the evening of June 15, 1988, Terry Nishimuta, an eighteen-year-old Fort Hood soldier, purchased a quart of beer at a Diamond Shamrock station in Waco. The store clerk did not require any identification from the underaged Nishimuta. Several hours later, while Nishimuta was returning to Fort Hood, his vehicle struck and killed Sergeant Edward Fuller and Private Ernest Zachary. The soldiers’ parents brought wrongful-death suits against several corporate entities and the manager of the store.
Appellants alleged causes of action for common law negligence and negligence per se for violation of section 106.03(a) of the Alcoholic Beverage Code, which provides:
A person commits an offense if with criminal negligence he sells an alcoholic beverage to a minor.
Tex.Alco.Bev.Code Ann. § 106.03(a) (Vernon Supp.1992). A minor is defined as a person under twenty-one years of age. Id. § 106.01.
Appellees moved for a summary judgment on the ground that Chapter 2 of the Alcoholic Beverage Code — commonly known as the “dram shop act” — provides the exclusive cause of action for damages based on a sale of an alcoholic beverage to a person eighteen years of age or older. See id. §§ 2.01-2.03. The exclusive remedy of Chapter 2 is “in lieu of common law or other statutory warranties.... ” Id. § 2.03.
Section 2.02 of the Code provides a cause of action against a provider of alcoholic beverages when “it is apparent to the provider that the individual being sold, served, or provided with an alcoholic beverage was obviously intoxicated to the extent that he presented a clear danger to himself and others; and the intoxication of the recipient of the alcoholic beverage was a proximate cause of the damages suffered.” Id. § 2.02(b) (emphasis added). Appellees presented Nishimuta’s deposition testimony as summary-judgment proof that he was eighteen and not intoxicated when he purchased the quart of beer. Nishimuta testified that he had consumed no alcoholic beverages before purchasing the beer and was completely sober at the time of the sale. Because Nishimuta was not “obviously intoxicated” as required by section 2.02(b)(1), Appellees moved for a judgment as a matter of law, which the court granted.
Appellants appeal on six points, alleging the court erred in granting the summary judgment because: its interpretation of the Alcoholic Beverage Code was incorrect, arbitrary, and capricious; they were denied their common-law cause of action; they were denied due process and equal protection under state and federal law; and they were denied protection under the Texas “open courts” provision.
In points one through three, Appellants argue that the court’s interpretation of Chapter 2 of the Alcoholic Beverage Code is incorrect, arbitrary and unreasonable, and denies them their common-law cause of action guaranteed by section 5.001 of the Civil Practice and Remedies Code. Appel-lees moved for summary judgment on the ground that Chapter 2 of the Alcoholic Beverage Code establishes the exclusive remedy for providing alcohol to any person eighteen years of age or older. Section 2.03 states:
Statutory Remedy
The liability of providers under this chapter for the actions of their customers, members, or guests who are or become intoxicated is in lieu of common law or other statutory law warranties and duties of providers of alcoholic beverages. This chapter does not impose obligations on a provider of alcoholic beverages other than those expressly stated in this chapter. This chapter provides the exclusive cause of action for providing *884 an alcoholic beverage to a person 18 years of age or older.
Id. § 2.03 (emphasis added). In contrast, section 106.03(a) prohibits the criminally negligent sale of alcoholic beverages to a minor — defined as a person under the age of twenty one. Id. § 106.03(a).
The Austin Court of Appeals, in a case arising from a sale of alcoholic beverages to an eighteen-year-old, held that an action under section 106.03(a) is barred because Chapter 2 creates the exclusive remedy for providing alcoholic beverages to a person eighteen years of age or older.
We may not ignore the Legislature’s express statement that chapter 2 is the exclusive cause of action for providing alcoholic beverages to a person eighteen years of age or older and that it is in lieu of any other statutory or common law duty of providers. Thus, we hold that chapter 2 means what it says and that it sets forth the exclusive cause of action for providing alcohol to a person eighteen years of age and older.
Boyd v. Fuel Distributors, Inc.,
Appellants’ rely on
El Chico Corp. v. Poole,
The legislature amended the Alcoholic Beverage Code to include a civil cause of action against an alcoholic beverage licensee when “at the time ... [of service] ... it was apparent to the provider that the individual being ... served ... was obviously intoxicated to the extent he presented a clear danger to himself and others.” Act of June 1, 1987; § 3 (to be codified at Tex.Alco.Bev.Code Ann. § 2.02) (emphasis added). The legislature appears to have created a much more onerous burden of proof for an injured plaintiff than we have in this opinion.
Id.
Appellants urge us to ignore
Boyd
and instead follow the reasoning of the San Antonio court in
Beard v. Graff,
Section 2.03 sets out the legislature’s clear intent that the dram shop act be the exclusive remedy for the sale of alcohol to persons eighteen years or older, in lieu of any other statutory or common law duty. Tex.Alco.Bev.Code Ann. § 2.03. We believe, as does the Austin court, that Chapter 2 of the Code is the exclusive remedy for damages for providing alcohol to a person eighteen years of age or older. See
id.; Boyd,
Appellants argue that they have a common-law cause of action against Appellees based on section 106.03 for sale of alcoholic beverages to a person under twenty-one years of age. Appellants argue that a holding that the dram shop act is the exclusive remedy for sale of alcohol to persons eighteen years of age or older will deprive them of their common-law cause of action in violation of the Texas Open Courts doctrine, due process and equal protection. See U.S. Const, amend. XIV; Tex. Const. art. 1, §§ 3, 13.
*885
Legislation violates the “open courts” provision of article 1, section 13, and is a denial of due process if its effect is to unreasonably abrogate a recognized right of recovery without substituting other reasonable remedies.
Weibel v. Martin Industries,
We will assume, without deciding, that Appellants have a common-law cause of action against Appellees for sale of alcoholic beverages to a “minor” — defined by the Alcoholic Beverage Code as a person under the age of twenty-one. The question then becomes: Did the legislature, in enacting the dram shop act as the exclusive remedy for sale of alcohol to persons eighteen and older, unreasonably abrogate Appellants’ right of redress?
See Weibel,
We note, as did the Austin court in
Boyd,
that with respect to administration of alcohol laws the legislature has seen fit to regulate the conduct and protect the interests of older minors differently from younger ones.
See Boyd,
The age of majority, except as provided by the Alcoholic Beverage Code, is eighteen. Tex.Civ.PRAc. & Rem.Code Ann. § 129.001 (Vernon Supp.1992). An eighteen-year-old can marry, vote, contract, and go to war. Parents are not liable for the actions of a child eighteen years of age or older. Tex.Fam.Code Ann. § 33.01 (Vernon 1986). In every respect, except under section 106.03 of the Alcoholic Beverage Code, an eighteen-year-old is by law an adult— presumably capable of making adult decisions. Thus, treating eighteen-, nineteen-, and twenty-year-olds the same as other adults for liquor liability purposes is not arbitrary and unreasonable.
Appellants argue that they are within a class of individuals that the legislature is seeking to protect from the consequences of minors’ purchases of alcoholic beverages, citing
Evans v. Joleemo, Inc.,
A strong presumption exists that a valid legislative enactment is constitutional.
Vinson v. Burgess,
*886 Appellants are not without a remedy. The dram shop act does not affect their right to bring a common-law cause of action against Nishimuta. See Tex. Alco.Bev.Code Ann. § 2.01. However, they cannot prevail against the provider of the alcohol unless they can prove that it was apparent to the provider that Nishimu-ta was obviously intoxicated at the time of the sale, was a clear danger to himself and others, and that his intoxication proximately caused Appellants’ damages. See id. § 2.02(b).
When a defendant moves for summary judgment without asserting an affirmative defense, it must disprove as a matter of law one or more of the elements essential to the plaintiff’s cause of action.
Anderson v. Snider,
Chapter 2 of the Alcoholic Beverage Code creates the exclusive remedy for providing alcoholic beverages to a person eighteen years of age or older. Tex. Alco.Bev.Code Ann. § 2.03;
Boyd,
The undisputed summary judgment evidence conclusively established that no genuine issue of material fact exists as to at least one element of each of the Appellants’ causes of action — obvious intoxication. Because there is no genuine issue of fact as to the element of intoxication, Appellees were entitled to judgment as a matter of law.
See Anderson,
We affirm the judgment.
