Which term describes an issue that a court is capable of deciding?

The term "justiciable" is used to describe issues that are appropriate for judicial resolution. In legal contexts, this refers to matters that can be decided by a court based on existing laws or legal principles. Justiciable issues typically involve concrete disputes where the parties have standing, and the courts have the authority to adjudicate such matters.

When a question is classified as justiciable, it means there are clear parameters, identifiable legal standards, and an actual case or controversy that allows the court to exercise its jurisdiction. This concept ensures that the judiciary addresses real issues rather than abstract questions that don’t have a direct impact or require legal interpretation.

The other terms do not convey the same legal significance. For example, non-justiciable issues are those that are outside the jurisdiction of the courts, often related to political questions or matters requiring policy decisions better left to other branches of government. Controversial issues might raise debate but don't necessarily indicate that the court can decide them legally. Irrelevant pertains to matters that have no bearing on the case at hand and would not fall under the purview of judicial review. Therefore, justiciable is the correct term that captures the essence of issues suitable for judicial determination.
