Pierce County, Washington v. Guillen, Legal Guardian of Guillen, Minors

Pierce County is asking the Supreme Court to decide if a federal law can block certain road safety records from being used in court. The county argues that without this protection, local governments would be afraid to collect data on dangerous roads.

This case affects how cities and counties manage road safety. If the Court rules against the law, local officials might stop identifying hazardous intersections to avoid legal liability, which could make roads less safe for everyone.

The case focuses on the Commerce Clause, which allows Congress to regulate things that impact interstate travel. The Court must determine if shielding state records from lawsuits is a valid way for the federal government to improve road safety.

Pierce County argues that the federal law is necessary to ensure states participate in safety programs without fear of lawsuits. Opponents argue that the law is too broad and prevents accident victims from accessing important information needed for their legal cases.

The ruling will clarify whether the federal government can legally protect state traffic safety data from being used as evidence in private legal battles.

The next major step is for the Supreme Court to schedule oral arguments. During that session, the justices will hear legal arguments from both Pierce County and the individuals challenging the law.

It is a federal program that provides funding to states to help them fix the most dangerous parts of their roads. To get the money, states must evaluate their roads and identify which areas need the most help.

Local governments are worried that if they create reports identifying dangerous roads, those reports will be used as evidence in lawsuits after accidents. They want to keep this data confidential to protect themselves from legal liability.

Section 409 is a federal rule that says information 'compiled or collected' for the safety program cannot be used as evidence in court. The dispute is about whether this rule is constitutional and how broadly it should be applied.

The federal government argues that because roads are used for interstate commerce, Congress has the power to pass laws that improve road safety. This includes protecting safety data to encourage states to participate in federal programs.

Some argue that the law should only protect documents that were specifically created for the federal program. They believe that if an agency already had the information for another reason, it should still be available to use in court.
