In 2020, the U.S. Supreme Court stopped the Trump administration from unilaterally rescinding the Deferred Action for Childhood Arrivals (DACA) program. The administration's attempted cancellation of DACA, which protects unauthorized immigrants who arrived in the United States as children, was "arbitrary and capricious" and exceeded the executive branch's lawful authority, Chief Justice John Roberts wrote for the majority.
In February, the Supreme Court heard Biden v. Nebraska, another case with far-reaching implications for executive authority. Unfortunately for President Joe Biden, the case reminded Roberts of his 2020 ruling against Trump.
