Congratulations, you found more people talking about subpoenas.
that subpoena was never valid as evidenced by this reply.
No, all that they had was a bunch of "opinion" which is meaningless.
Of the only court case they tried to use, the ruling was because of the scope of congresses request and the court implied if they had narrowed it, they might have had a better case and won. As a result of stepping outside the bounds of what they were permitted, the Court decided that they violated the constitution in terms of free speech and press. This impeachment is a completely different beast and nothing about that case is applicable.
No, its called "law" upon which all of your claims are dependent. What you have are opinions. None of those subpoenas were valid or enforceable. This whole issue of ambiguity was the entire intent for issuing them as I explained from the start. It was designed to give the impression of moving forward with impeachment while not actually doing so and giving the executive and the Republican party the authority to subpoena their own evidence and witnesses which would destroy the dems. Even after the vote here they are running a one sided sham excuse for due process.
