Why It Matters
Federal courts are able to block or reshape government policy long before a case reaches final judgment when the policy is contested in a civil suit. A new Congressional Research Service (CRS) report published Oct. 6 makes clear that interim rulings often carry the most immediate practical weight.
The report is a procedural primer on how civil suits against the federal government move through the courts, written to help legislators estimate timelines and weigh the significance of rulings at each stage of litigation.
The CRS report describes how court orders such as preliminary injunctions, which are intended to apply temporarily, can have significant practical impact and sometimes effectively resolve a case, and notes that emergency litigation can move from filing in district court to a Supreme Court decision in months or days.
The Big Picture
Most suits begin in federal district court with a complaint, followed by a government response, and then potentially discovery, summary judgment, and trial. The CRS report says that in some cases challenging a federal agency action, review is based on the agency's administrative record for that action, and discovery is not conducted.
CRS reports that in the year ending June 2026, civil cases in district courts had a median of 33.7 months from filing to trial, and more than 26% had been pending for over three years. Because federal policies often affect broad geographic areas, plaintiffs may be able to choose from among multiple eligible districts, a practice sometimes called forum shopping.
Appeals generally must follow a final district-court decision, but grants or denials of injunctions and denials of sovereign immunity can be appealed before the case concludes. In civil cases where the United States is a party, appeals must be filed within 60 days, and CRS reports a median of just over ten months from notice of appeal to decision for the period between June 2025 and June 2026.
At the Supreme Court, a party has 90 days to file a certiorari petition, and four of the nine justices must vote to grant it. CRS notes the Court receives approximately 7,000–8,000 petitions annually, grants 50–80, and that the United States is involved in roughly two-thirds of the Court's merits cases each year.
Preliminary injunction orders are immediately appealable. The report cites Bush v. Gore as a historical example of litigation briefed, argued, and decided within a few days.
The Bottom Line
The report establishes that procedural choices, including venue selection, requests for interim relief, and appeal timing, can affect both the outcome of a challenge to federal action and when that outcome takes effect.
