Board of Trustees of the University of Alabama v. Garrett531 U.S. 356, 368 (2001)
Patricia Garrett, a registered nurse, served as Director of Nursing for OB/Gyn/Neonatal Services at the University of Alabama in Birmingham Hospital. In 1994 she was diagnosed with breast cancer and underwent a lumpectomy, radiation treatment, and chemotherapy that required substantial leave from work. Upon returning in July 1995, her supervisor informed her that she would have to relinquish the director position, leading Garrett to apply for and accept a transfer to a lower-paying nurse manager role.
Milton Ash worked as a security officer for the Alabama Department of Youth Services. At the outset of his employment, Ash notified the department of his chronic asthma and, on his doctor's recommendation, requested modifications to minimize exposure to carbon monoxide and cigarette smoke. After later being diagnosed with sleep apnea, Ash sought reassignment to daytime shifts pursuant to medical advice. The department denied all requested accommodations. Shortly after Ash filed a discrimination claim with the Equal Employment Opportunity Commission, his performance evaluations declined below previous levels.
Garrett and Ash filed separate lawsuits in the United States District Court for the Northern District of Alabama, each seeking money damages under Title I of the ADA against their state employers. The state defendants moved for summary judgment, asserting that the ADA exceeds Congress's authority to abrogate Eleventh Amendment immunity. In a single opinion, the district court granted the motions and dismissed both cases. The cases were consolidated on appeal to the Eleventh Circuit, which reversed based on its prior decision in Kimel v. State Board of Regents holding that the ADA validly abrogates state immunity. The Supreme Court granted certiorari to resolve a split among the courts of appeals regarding whether individuals may sue states for money damages in federal court under the ADA.
Who bears the burden of proving contributory negligence in a negligence action?
The defendant bears both the burden of production and the burden of persuasion on contributory negligence because it is an affirmative defense. The plaintiff must prove the elements of the negligence claim but need not disprove his own fault. If the defendant fails to persuade the factfinder that the plaintiff's conduct was negligent and contributed to the harm the defense fails.

What happens when a party with the burden of production fails to meet it?
The issue is decided against that party as a matter of law. The opposing party may obtain judgment on that issue without the factfinder ever weighing the evidence because no sufficient evidence was introduced to create a triable question.

Does the burden of persuasion ever shift during trial?
The burden of persuasion remains fixed on the party to whom it was initially assigned. Only the burden of production may shift after a prima facie showing is made. The party that bears the ultimate burden of persuasion must still convince the factfinder even if the opponent produces rebuttal evidence.
