Full Text of Rule 1.458
Plain-English Summary
Rule 1.458 addresses a narrow but practical mismatch: a petitioner sues under the right facts but asks for the wrong remedy. In cases of mandamus, certiorari, an appeal to the district court, or a suit for specific equitable relief, if the facts pleaded and proved don't entitle the petitioner to the specific remedy demanded, but do show entitlement to some other remedy, the court has to let the petitioner amend and ask for that different remedy instead — and the court may then award it.
The court can attach terms to that amendment if it prescribes them, but the underlying permission to amend isn't optional once the facts support a different remedy than the one requested. The rule functions as a safety valve limited to this specific set of special proceedings, favoring substance over a technical mismatch in the relief requested.
