Every state has its own mandamus framework, and the differences from federal practice can be significant.
While federal mandamus is anchored primarily in 28 U.S.C. § 1361 and the All Writs Act, each state has developed its own statutory and common-law framework for mandamus, often with meaningfully different procedures.
Different names, similar concepts
Some states call the remedy a "writ of mandate" rather than mandamus (California is the best-known example), while New York replaced the traditional writ with a unified "Article 78 proceeding" that covers mandamus along with certiorari and prohibition. The underlying logic remains similar even where the label changes.
Different courts, different starting points
Federal mandamus against a federal officer starts in district court. State mandamus procedures vary: some states allow filing in the trial court level, while others give appellate courts or even the state supreme court original jurisdiction over certain mandamus petitions, particularly those involving statewide officials.
Different standards of review
Some states apply a test very close to the federal three-part standard; others use a more flexible "abuse of discretion" framework, or explicitly authorize mandamus to address a broader range of "clear legal duties" without the same strict federal-style discretion analysis.
Why the distinction matters practically
A dispute involving a state agency, a county office, or a local school board will virtually always be governed by state mandamus law, not federal law, even if federal constitutional issues are also present. Petitioners need to identify the correct body of law before drafting, since citing federal mandamus statutes in a state petition is a common and avoidable mistake.
When both systems can be relevant
Some disputes implicate both systems — for example, a state official administering a federally funded program. In these cases, understanding which duty arises from state law and which from federal law is essential to choosing the correct forum and legal theory.
