Do judges have the power to enforce their rulings if the executive branch refuses to comply?

Since Donald Trump was first elected President, in 2016, scholars of authoritarianism have warned that American democracy is under grave threat. On various occasions, that threat has been defined as a “constitutional crisis,” which generally refers to a branch of government defying or usurping the constitutional powers of another branch. (One certainly would have occurred had Mike Pence refused to certify the 2020 election results.) In recent weeks, a number of law professors have invoked the term to describe the current moment, in which the Trump Administration has fired government employees who have civil-service protections mandated by Congress, tried to end birthright citizenship despite its guarantee by the Constitution, and released an executive order that postpones the enactment of a law passed by Congress about the sale of TikTok.
