Case Overview
The government appealed Judge Leon's order which halted the construction of the White House ballroom.
The Application
History
Judge Leon halted the ballroom construction project, finding the government failed to comply with NHPA consultation procedures before approval. The government appealed, contending either that the White House is exempt from NHPA consultation requirements or that adequate notice and opportunity for comment were provided.
The Conclusion
The CADC affirmed or reversed Judge Leon's preliminary injunction, determining whether federal agencies must comply with NHPA consultation procedures for executive branch property and whether the government satisfied those requirements.
