Nationwide Injunctions: Key Check on Presidential Power Remains

Nationwide injunctions are still a powerful tool against presidential policies. Both Donald Trump and Joe Biden have asked the Supreme Court to eliminate them, but the practice isn’t dead yet. In June 2025, the Court did limit their use in the Trump v. CASA case, which aimed to lift nationwide injunctions on Trump's immigration policies. White House Counsel David Warrington claimed the decision restored separation of powers, but that’s not entirely accurate. In fact, just weeks after the CASA ruling, a federal judge blocked Trump's executive order on birthright citizenship, showing that other legal avenues still exist for courts to intervene. What's interesting is that both administrations have voiced frustrations over these injunctions. Biden's Solicitor General, Elizabeth Prelogar, argued against them in a separate case concerning the Corporate Transparency Act. The bottom line is that nationwide injunctions remain a significant check on presidential authority, ensuring that policies can still face legal scrutiny across the country. This matters because it affects how laws are implemented, directly impacting millions of Americans.
