Distinguish between the following: Prohibition Writ and Certiorari Writ.

Prohibition Writ The writ of prohibition is issued by the Supreme Court or any High Court to an inferior Court preventing the latter from usurping jurisdiction which is not legally vested in it. It compels courts to act within their jurisdiction when a tribunal acts without or in excess of jurisdiction or in violation of rules or law. The writ of prohibition is available only against judicial or quasi-judicial authorities and is not available against a public officer who is not vested with judicial functions. If abuse of power is apparent this writ may be prayed for as a matter of right and not a matter of discretion. The Court may issue this writ only in case of Fundamental Rights being affected by reason of the jurisdictional defect in the proceedings. This writ is available during the pendency of the proceedings and before the order is made. Certiorari Writ The writ of certiorari is available to any person whenever anybody of persons having legal authority to determine questions affecting the rights of subjects and having the duty to act judicially, acts in excess of its legal authority. The writ removes the proceedings from such body to the Court in order to quash a decision that goes beyond the jurisdiction of the deciding authority.
