## Facts

- Congress enacted the Reconstruction Acts of March 2 and March 23, 1867, establishing military districts in certain former Confederate states and directing presidential implementation, including military assignments and voter-registration measures.
- The State of Mississippi sought to prevent enforcement of these Acts within Mississippi, alleging the statutes were unconstitutional.
- Mississippi moved in the U.S. Supreme Court for leave to file an original bill in equity seeking a perpetual injunction against President Andrew Johnson and executive agents, including the district military commander.
- The requested relief would have restrained the President from executing and carrying out the Reconstruction Acts.

## Issues

1. Whether the Supreme Court could entertain an original bill seeking to enjoin the President from executing an act of Congress alleged to be unconstitutional.
2. Whether the President’s responsibilities under the Reconstruction Acts were ministerial (judicially enforceable) or discretionary executive and political duties (not subject to injunctive control).

## Decision

- The Court unanimously denied Mississippi’s motion for leave to file the bill.
- The Court held it had no jurisdiction to enjoin the President in the performance of official duties.
- The Court concluded the duties involved in executing the Reconstruction Acts were executive and political, not ministerial.
- The Court stated it made no difference that the bill described Johnson as a citizen as well as President; the requested injunction targeted official presidential action.

## Legal Principles

- Courts will not restrain the President by injunction from carrying into effect an act of Congress, even when the statute’s constitutionality is challenged.
- Judicial relief may be available for purely ministerial executive duties that are specific, mandatory, and involve individual rights; it is unavailable for discretionary executive and political functions.
- Separation of powers limits judicial control over presidential discretion in executing federal law, and an injunction against the President raises enforcement and institutional-competence concerns.

## Conclusion

The Supreme Court refused to permit an original equitable action seeking to stop presidential enforcement of the Reconstruction Acts, holding that the judiciary lacks jurisdiction to enjoin the President in performing discretionary executive and political duties.
