> truth-finding function

Lower courts typically deal with questions of fact and how they intersect with questions of law; higher courts (appeals courts and Supreme Court) typically deal with questions of law (ambiguity/interpretation) exclusively. Courts as an institution don't serve a "truth-finding function" so much as a "law-ambiguity removing function".

> disparage > impugn

Everyone seems focused on whether a court has the right to, like, insult the president personally. But that's not really the important part of what they're doing. They _of course_ have the right to question whether the law allows what the president is doing -- and questioning this is not disparagement or impugning.
