Mootness

And mootness is the exact opposite.

Right.

Mootness is marching up to the referee on a Tuesday asking for a penalty on a game that ended last Friday.

Yes.

The controversy was live at one point, but events happened in the real world that made it impossible for the court to provide any meaningful relief.

Are they purely legal questions, or do we need more factual development against a hardship to the parties of withholding court consideration?

Mootness is the other end of the timeline.

A case is moot if there is no longer a live, ongoing controversy.

If events happen during the litigation that make it impossible for the court to provide meaningful relief, the case must be dismissed.

Right, that's ripeness.

Mootness, on the other hand, asks if the live controversy has died.

So if you sue demanding a spec-specific government document and the government just hands it over during discovery, the case is moot.

A federal court won't issue a ruling just to make a point.

Got it.

And the mirror image of ripeness is mootness.

Mootness asks, "Is it too late?"

Does the case lack a live controversy? Because Article III requires a live controversy throughout all stages of the litigation, not just when you file the complaint.

Yes, all the way through appeals.

And mootness is the exact inverse.

The case was brought too late.

Mootness requires that an actual controversy must exist at all stages of appellate or certiorari review, not just when the action is filed.

So if during the course of litigation, the challenged law is repealed or the parties settle or the plaintiff's specific injury is irreversibly resolved, the case is moot and the court has to dismiss it, any ruling at that point would be an advisory opinion.

But mootness is fraught with exceptions, and the most heavily tested exception on any exam is for wrongs that are capable of repetition, yet evading review.
