A Writ of Prohibition is an order issued by the Supreme Court or High Courts to :

Answer (c) & explanation

Prohibition stops a lower court from continuing a case (c). A writ of Prohibition is issued by a higher court to a lower court or tribunal, telling it to stop a case it has no jurisdiction to hear. It is issued only to judicial and quasi-judicial bodies. Option (a) is wrong: it is never issued to a government officer. Options (b) and (d) are wrong: courts cannot use it against Parliament, a legislature or the government's policy.

Notice the five writs under Articles 32 and 226: Habeas Corpus (produce the person), Mandamus ("we command", to perform a duty), Prohibition, Certiorari and Quo Warranto (by what authority). Think of Prohibition as "stop before you decide", and Certiorari as "your decision is quashed".

Trap

option (a) describes mandamus in reverse. Prohibition is aimed at courts, not officers.

Answer as per the official UPSC answer key.
