Question

Quizplus · Accepted Answer

A court uses all of the legal doctrines listed (ripeness, standing, and res judicata) to determine whether a case is justiciable. Ripeness refers to whether a dispute has developed to a point where the court can make a decision that will have a concrete impact on the parties. Standing refers to whether the plaintiff has a sufficient stake in the outcome of the case to justify the court's involvement. Res judicata refers to whether the case has already been decided by another court and therefore cannot be heard again.
