They didn't "update" an exhibit. They removed the subject.
This memo opinion says the National Park Service likely acted unlawfully when it removed slavery-related materials from the President's House site at Independence National Historical Park without the City's required consultation/mutual agreement, and that the City is likely to succeed on the merits at the preliminary-injunction stage.
Key points from the opinion itself:
• The opinion states that on Jan. 22, 2026, NPS removed 34 educational panels and deactivated related videos at the President's House exhibit that referenced slavery and the people Washington enslaved.
• The City sued under the APA; the court finds the City has standing tied to Congress-authorized cooperative agreements and the City's role/funding in the exhibit.
• The court treats the removals as final agency action reviewable under the APA (not just "day-to-day operations").
• On the preliminary record, the court concludes the City is likely to show the removals were arbitrary and capricious because they disregarded governing constraints (including mutual-assent requirements and the site's agreed interpretive framework).
Question: What would the administrative record need to show for this kind of exhibit removal to be lawful under the APA?
