Headline: Decision reverses a court order forcing the Navy to prepare a hypothetical environmental study about nuclear-capable storage and allows classified military information to be withheld under FOIA, limiting public disclosure of EIS documents.

Holding:

Real World Impact:

Allows the military to withhold classified EIS information from the public under FOIA Exemption 1.
Requires agencies to consider environmental effects internally even when public disclosure is barred.
Limits courts’ ability to force preparation of hypothetical public studies that would reveal secrets.

Summary

Background

The Navy decided to move ammunition and weapons on Oahu to a West Loch storage area and built 48 earth-covered magazines. An internal Environmental Impact Assessment said construction posed no significant environmental effect, so no public Environmental Impact Statement was issued. The magazines are "nuclear capable," and the Navy's rules bar it from admitting or denying whether nuclear weapons are stored there because that information is classified. An environmental group sued in 1978, asking a court to block use until an EIS was prepared; a district court called the project a major federal action but found the Navy had complied "to the fullest extent possible."

Reasoning

The Court addressed whether the Ninth Circuit properly required a "hypothetical" public EIS. It held that NEPA’s public-disclosure requirement is subject to the Freedom of Information Act, and FOIA Exemption 1 lets the Government withhold properly classified national security information. The Ninth Circuit had created a judge-made "hypothetical" EIS that NEPA and FOIA do not mandate. The Court said the Navy must consider environmental effects in its internal decisionmaking, but it need not prepare or disclose a public hypothetical EIS when disclosure would reveal classified material. Whether the Navy actually proposed storing nuclear weapons— which would trigger an internal EIS— cannot be established in this case because the facts are classified.

Real world impact

The ruling lets the military keep classified information, including existence or details of certain environmental studies, from public release when national security rules apply. It preserves agencies’ obligation to consider environmental consequences internally even when public disclosure is barred. The decision reverses the appeals court and reinstates dismissal, leaving the underlying question of a proposed nuclear storage plan unresolved and not finally decided by this opinion.

Dissents or concurrances

Justice Blackmun, joined by Justice Brennan, agreed with the outcome but stressed that agencies must prepare EISs for proposed classified actions, and must release any nonclassified portions when feasible by segregating classified annexes.
