The U.S. Supreme Court will review EPA regulation challenges, addressing jurisdiction for filing.

The U.S. Supreme Court will hear cases challenging the Environmental Protection Agency's (EPA) regulations, particularly focusing on the practice of "judge shopping" by conservative groups favoring the Fifth Circuit Court of Appeals. The court's review will address whether such regulatory challenges should be filed in the District of Columbia Circuit, as the Biden administration argues. This decision could significantly impact the future of EPA rules and the balance of appeals courts.
