What does a writ of prohibition prevent?

A writ of prohibition is a judicial order that prevents a lower court or a government official from acting outside their jurisdiction. Its primary purpose is to ensure that lower courts do not exceed the lawful authority granted to them and do not overstep their boundaries. This judicial tool is meant to maintain the proper functioning of the legal system and to uphold the rule of law by preventing actions that may be deemed unlawful or outside the scope of authority.

The significance of this writ lies in its ability to protect the integrity of the judicial system and government functions. When issued, it effectively halts proceedings or actions that are considered to be unauthorized, thus preventing potential harm from occurring due to those actions. The breadth of the writ assures that it applies not just to lower courts but also to government officials, ensuring that all actions taken are within the bounds of their legal authority.

This comprehensive nature of the writ, covering both lower courts and government officials, aligns with the selected answer. It underscores the fundamental principle that all entities operating within the legal framework must abide by established jurisdictions and limits of authority.
