Pierce County v. Guillen

The Hazard Elimination Program provides state governments with funding to improve the most dangerous sections of their roads. To be eligible for funding, a state must undertake a thorough evaluation of its public roads. This led to concerns that the absence of confidentiality would increase the liability risk for accidents that took place at hazardous locations before improvements could be made. Ultimately, Congress provided that materials "compiled or collected" for purposes of the program "shall not be subject to discovery or admitted into evidence in a Federal or State court proceeding." In 1996, Ignacio Guillen's wife died in an automobile accident in a Pierce County, Washington intersection. While Washington had previously been denied funding for the intersection where the accident occurred, its second request was granted after the accident. Guillen first sought information on the intersection and then asserted that the state had been negligent in failing to install proper traffic controls. Washington sought to protect itself under the Program. The Washington Supreme Court held that the Program exceeded Congress's power under the Constitution.
