Lawsuits challenging Trump policies raise big constitutional questions, but they also rely on a law that requires the government to follow the correct procedures when changing course.

Summary

Trump’s policies are facing legal setbacks due to the Administrative Procedure Act (APA), a 1946 law requiring agencies to justify policy changes.

Courts have blocked several administration actions, including funding freezes and biomedical research cuts, citing “arbitrary and capricious” decision-making.

The APA previously derailed Trump’s first-term efforts, including his census citizenship question and DACA rollback. While the administration may correct errors, critics argue its rushed policymaking invites legal challenges.

Trump allies, including Elon Musk, have attacked judges, but the White House vows to keep fighting in court.
