United States Fish and Wildlife Serv. v. Sierra Club, Inc.
The Supreme Court ruled that internal draft biological opinions prepared by federal wildlife agencies are protected from public disclosure under the Freedom of Information Act, because the agencies never treated them as final decisions.
The ruling clarifies when government agencies can shield working documents from disclosure requests, drawing a line between documents that represent an agency's settled position and those that are still part of an ongoing deliberative process.
“A document is not final solely because nothing else follows it. Sometimes a proposal dies on the vine.”
The majority explaining that a document is not a final agency decision just because nothing came after it.
How it got here: A federal district court ruled the draft opinions must be disclosed; the Ninth Circuit affirmed; the wildlife agencies asked the Supreme Court to step in and the Court agreed to hear the case.
The Case in Depth
What happened
The EPA was writing a rule on "cooling water intake structures" — industrial systems that can trap and kill aquatic wildlife. Because the rule could affect endangered species, federal law required consultation with the U.S. Fish and Wildlife Service and the National Marine Fisheries Service. Staff at both agencies drafted opinions in late 2013 concluding the EPA's proposed rule would likely harm certain species. Agency decision-makers shelved those drafts and continued negotiating with the EPA, which eventually produced a revised rule that the agencies approved. The Sierra Club, an environmental group, sued under the Freedom of Information Act to obtain the shelved draft opinions.
The question before the Court
Can federal wildlife agencies use the deliberative process privilege to withhold their internal draft biological opinions about a proposed EPA rule from public release under the Freedom of Information Act?
The Court's answer
Yes — the deliberative process privilege protected these documents from disclosure. The Court held that the draft biological opinions were shielded because the agencies never treated them as final. Agency decision-makers neither approved the drafts nor forwarded them to the EPA; instead they shelved the documents and extended consultation, meaning the drafts were really "drafts of draft biological opinions" — far from any settled agency position.
The Court rejected the argument that the drafts became "final" simply because they may have prompted the EPA to revise its proposed rule. What matters under the privilege is not practical influence but legal consequence: only a formally issued final biological opinion carries direct legal force and changes the EPA's obligations. Because these drafts lacked that status and were never adopted by agency decision-makers, they remained predecisional and deliberative documents protected under Exemption 5 of FOIA.

Why it matters
Environmental and public interest groups that use the Freedom of Information Act to monitor how federal agencies interact during rulemaking will find it harder to obtain internal draft documents — even when those drafts may have shaped the final outcome. Federal agencies now have clearer authority to protect staff-level working papers from disclosure as long as decision-makers never formally adopted them.
What changes now
The case is sent back to lower courts. The district court must determine whether any portions of the withheld documents can be "segregated" — meaning separated from the privileged content and disclosed on their own — as FOIA requires agencies to release any reasonably separable non-exempt portions. The core ruling protecting the draft opinions from disclosure stands, but some pieces of the documents may still need to be released if they can be separated from the privileged deliberative content.
What this does not decide
The Court did not decide whether a draft biological opinion would be protected in all circumstances. It left open the possibility that a draft could be treated as final if, for example, an agency made clear it would not change its environmental conclusions in response to the action agency's feedback. The ruling also does not address segregability of specific document portions.
Concurrences and dissents
Dissent — Justice Breyer
Justice Breyer argued that Draft Biological Opinions — as distinct from mere Drafts of Draft Biological Opinions — are functionally final documents that should not be shielded from FOIA disclosure. He pointed to five factors: Draft Biological Opinions serve the same purposes as Final Biological Opinions, they trigger the same choices for the EPA, agency practice treats them as effectively final, staff already know they may be made public, and they carry regulation-based legal consequences. He would have remanded to the Ninth Circuit to assess which of the specific documents were true Draft Biological Opinions versus earlier-stage drafts.
How the Court got there
The legal reasoning, step by step
- The Freedom of Information Act's Exemption 5 incorporates the deliberative process privilege — a rule that protects from public disclosure documents reflecting an agency's internal deliberations about a policy, as opposed to documents that embody the agency's final decision. To qualify for protection, a document must be both 'predecisional' (created before the final decision) and 'deliberative' (prepared to help shape the agency's position).
- The Court emphasized that whether a document is 'final' is a functional question, not a formal one. A document is not final simply because nothing came after it — sometimes a proposal 'dies on the vine' and is never acted upon. What matters is whether the agency itself treated the document as representing its settled view, and whether the document had direct legal consequences.
- The Court rejected the Sierra Club's argument that the drafts were final because they had a practical 'operative effect' — meaning they apparently prompted the EPA to revise its proposed rule. The Court clarified that 'operative effect,' as used in its prior precedent, refers to legal consequences, not practical ones. A final biological opinion legally constrains what the EPA can do; a draft opinion does not carry the same legal weight.
- The draft opinions here were prepared by lower-level staff and submitted to agency decision-makers for approval. Those decision-makers never approved the drafts, never forwarded them to the EPA, and instead concluded 'more work needed to be done' — extending the consultation period. This meant the documents were not even true draft biological opinions, but rather 'drafts of draft biological opinions,' multiple steps away from any final agency position.
- Because the agencies never treated the documents as their final views, and because the documents lacked direct legal consequences, they were both predecisional and deliberative. The deliberative process privilege therefore applied, and the agencies were entitled to withhold them from the Sierra Club's FOIA request.
