In order for an issue to be justiciable, it must meet certain criteria. First, it must be a real and substantial controversy. This means that it must be a dispute that actually exists, and it must not be hypothetical or speculative. Second, the issue must be ripe for decision. This means that it is ready to be decided by a court, and it is not premature or hypothetical. Third, the issue must be fit for judicial review. This means that it is a matter that the court can resolve using its legal authority and powers.
If an issue meets all of these criteria, then it is justiciable. This means that a court can hear and decide the case, and it can provide a remedy for the winning party.
