Mootness means a case no longer presents a live dispute that the court can meaningfully resolve.
Why It Matters
This doctrine matters because courts generally decide real, current controversies rather than abstract or expired disagreements. If the underlying problem disappears, the court may conclude there is no longer a justiciable case.
Where It Appears
Mootness appears in constitutional, administrative, election, school, benefits, and injunction cases when circumstances change after the lawsuit begins.
Practical Example
A policy challenged in court is fully withdrawn before the court rules, and the plaintiff no longer faces the disputed burden. The court may examine whether the case is now moot.
How It Differs From Nearby Terms
Standing focuses on whether the plaintiff had the right to sue at the start. Ripeness focuses on whether the dispute developed enough to sue yet. Mootness asks whether the case has stopped being live after filing.
