20801, Inc. v. Parker (2008)
Individual Responsibility-Dram Shop Act-Safe Harbor Provision
Issue: Under the safe harbor provision of the Texas Dram Shope Act, does a provider of alcohol have to prove that he did not directly or indirectly encourage his employees to over-serve alcohol in order to receive immunity from the liability associated with employees over-serving patrons.
Factual and Procedural History: In November 1999, Defendant's employees served Plaintiff ten to fifteen free alcoholic beverages at the opening of their pool hall. After Plaintiff became involved in an argument with another patron, Defendant asked Plaintiff to leave. After leaving, Plaintiff was punched by the other patron in the parking lot, which caused Plaintiff to fall and strike his head on the pavement. Plaintiff brought suit for damages, but the trial court granted Defendant's Motion for Summary Judgment. In response, the Court of Appeals reversed, holding that Defendant did not establish that they did not encourage their employees to violate the law. The Supreme Court of Texas granted Defendant's petition of review to explore the contours of the safe harbor provision.
Relevant Rule: The Texas Dram Shop, which imposes liability on alcoholic beverage providers for damages resulting from the provision of alcohol to obviously drunk persons, also contains a section eliminating this liabilitiy if (1)the employer requires its employees to attend certain training classes, (2) the employee in question actually attended these classes, and (3) the provider did not directly or indirectly encourage that employee to violate the law.
Summary: Justice Harriet O'Neill concurred with the unanimous opinion, authored by Wallace Jefferson, which ruled that a provider of alcohol does not have the burden of disproving encouragement to over-serve alcohol in oder to realize the benefits of the safe harbor clause of the Texas Dram Shop Act. The court held: (1) the provider bears the burden of establishing the first two elements of the safe harbor provision (2) the plaintiff bears the burden of establishing direct or indirect encouragement, and (3) encouragement may be shown, at the minimum, by evidence of the provider's negligence.
