## Facts

- President George W. Bush created the National Energy Policy Development Group (NEPDG) in 2001, chaired by the Vice President, to develop recommendations on national energy policy.
- After NEPDG issued its report and ceased operations, Sierra Club and Judicial Watch sued, alleging NEPDG violated the Federal Advisory Committee Act (FACA) by not providing public access and disclosures.
- Plaintiffs alleged private individuals, including energy-industry representatives, regularly attended and participated in NEPDG meetings as de facto members, making NEPDG ineligible for FACA’s exemption for committees “composed wholly” of federal officials.
- Plaintiffs sought declaratory and injunctive relief compelling production of NEPDG-related records.
- The district court allowed limited discovery into NEPDG’s structure and membership, deferring rulings on mandamus availability and certain separation-of-powers objections.
- The D.C. Circuit denied mandamus to halt discovery, reasoning the Executive could raise executive privilege on a document-by-document basis.
- The Supreme Court granted review limited to whether mandamus should issue to prevent or constrain discovery directed at the Vice President and other senior executive officials.

## Issues

1. Whether the court of appeals applied the correct standard in denying mandamus relief from discovery orders directed at the Vice President and other senior Executive Branch officials.
2. Whether separation-of-powers concerns required a more protective threshold approach to discovery in litigation probing internal executive deliberations.
3. Whether lower courts should consider narrower statutory and procedural grounds before permitting intrusive discovery that could precipitate executive-privilege conflicts.

## Decision

- The Supreme Court vacated the judgment denying mandamus and remanded for reconsideration.
- The Court held the D.C. Circuit treated the matter too much like an ordinary discovery dispute and did not give sufficient weight to separation-of-powers concerns.
- The Court emphasized that broad discovery into high-level executive advisory processes can impose burdens distinct from ordinary litigation by forcing premature disclosure pressures or privilege confrontations.
- The Court did not decide whether FACA applied to NEPDG or whether FACA would be unconstitutional as applied; it addressed only the standard governing mandamus and the handling of discovery.

## Legal Principles

- Mandamus is an extraordinary remedy requiring (1) no other adequate means to obtain relief and (2) a clear and indisputable right to issuance of the writ.
- When discovery targets the President, Vice President, or close advisers concerning internal deliberations, courts must account for separation-of-powers interests at the outset, not only through later privilege claims.
- Courts should, where feasible, resolve statutory and threshold questions in ways that reduce or avoid constitutional conflicts between branches, including by narrowing construction and sequencing issues before authorizing intrusive discovery.
- A requirement that the Executive assert privilege document by document is not always an adequate substitute for assessing whether the discovery demands themselves improperly intrude on Executive Branch functions.

## Conclusion

The Court required the court of appeals to reconsider mandamus with heightened attention to separation-of-powers concerns implicated by discovery into senior executive deliberations, while leaving unresolved whether FACA applied to the NEPDG or could constitutionally be enforced in this context.
