A U.S. District Judge in Boston issued a preliminary injunction ordering the Interior Department to restore removed signs and exhibits in national parks within 21 days, aligning with the nation’s upcoming 250th anniversary.

The injunction comes at the request of park conservationists, historians, and scientists who argue the administration has been erasing history and suppressing scientific facts.

The ruling blocks the administration’s censorship of exhibits that did not fit its political narrative while the broader lawsuit proceeds.

Supporters hail the decision as a victory for accuracy and truthful representation in public exhibitions.

The decision builds on prior actions restoring signs related to George Washington’s enslaved people and reflects a coalition’s view that the signs should present a fuller, more accurate history.

Interior officials had defended their policy as necessary to tell the full and accurate story of American history, arguing removals were justified under this mandate.

The court ordered restoration of the removed language within 21 days, underscoring the goal of honoring the United States’ 250th anniversary.

Affected sites include Independence National Historical Park, the Selma to Montgomery National Historic Trail, Glacier National Park, the Grand Canyon, and other locations featuring panels on slavery, climate change, and women’s history.

Other courts have ordered reinstallations of removed exhibits on topics like slavery, climate change, and LGBTQ+ history, reinforcing a pattern of restoration across sites.

The court found national parks should function as truthful living classrooms and rejected the government’s standing defense, noting direct harm from resource diversion to oppose deletions.

The case follows President Trump's March 2025 executive order directing the Interior Department to address what he called a revisionist portrayal of history and to modify parks and monuments accordingly.

Background shows removals occurred after the executive order and related directives, with watchdogs noting extensive changes to signs across sites.
