Which set of standards governs temporary relief in Article 78 proceedings?

• A. Likelihood of success on the merits
• B. Irreparable harm
• C. Balance of equities
• D. Likelihood of success on the merits, irreparable harm, and balance of equities

Answer: (D)

In Article 78 proceedings, temporary relief is governed by a three-part standard. The petitioner must show a reasonable likelihood of success on the merits, that irreparable harm will occur if relief is not granted, and that the balance of equities favors granting relief when weighed against the burden on the opposing party and any competing public interests.

Likelihood of success on the merits means there is a substantial question about whether the agency acted lawfully, within its authority, or in a rational, non-arbitrary way. Irreparable harm requires showing harm that cannot be adequately remedied later by a final decision, so waiting for a full resolution would cause damage that cannot be undone. Balance of equities asks the court to weigh the petitioner’s hardship if relief is denied against the potential burden on the agency and any broader public consequences if relief is granted.

All three factors together ensure that temporary relief is appropriate only when there is a real chance of a favorable ruling and the equities favor preventing ongoing or irreparable harm while the petition is resolved. The other options miss some essential piece of this protective framework.
