In the student loan case, SCOTUS held that the text of the law passed by Congress allowed Biden to do exactly what he did, but the GOP Justices didn't feel like he should, and therefore they were not going to let him.

@maxkennerly Just read the opinion and the dissents and....for me, the majority has the better argument. "the words 'waive or modify' do not mean 'completely rewrite' " -- that seems pretty obviously correct.
@PaultheFossil @maxkennerly Please consult a dictionary, because you do not know what "waive" means. You are literally, definitionally, wrong.
