Rule 81.Relief heretofore available by common law writs.

Before Rule 81, someone who wanted a court to order an official to act, stop a lower tribunal from exceeding its authority, or challenge a person's right to hold office had to invoke one of several old common-law writs by name: mandamus, prohibition, scire facias, quo warranto, or an information in the nature of quo warranto. Each writ came with its own technical rules for how to ask for it.

Rule 81 folds all of that relief into the regular civil action. A person seeking what a writ of mandamus or prohibition used to provide now files an original action in the appropriate court, using the same procedural rules that govern any other civil case. The underlying relief survives; the separate writ procedures do not.

This matters for anyone trying to compel a public official to perform a duty, stop a court or agency from acting beyond its authority, or contest someone's authority to hold an office. The relief is available, but it comes through an ordinary lawsuit rather than a specialized writ petition.
