count brought records/letters between johannes and himself throughout his sickness(?) until his death, proving that he was lucid and sound of mind when he wrote the letter that shuli submitted as evidence (the one that said they had no sexual relations).
madam reicher (the old woman/the count's mom) came with the count to remedy the count's reputation, since he was a shut-in who didn't socialize with nobles. if she's there, a respected general, other nobles can't badmouth the count and disregard the evidence he brought.
once proven that the letter was genuine, shuli can now apply for a divorce and pass the position of head of neuchwanstein to jeremy, so that jeremy can request for a duel of honor, as head of house, to escape this sham of a trial.
ofc the priests argued why in the first place did shuli and johannes married if there are no sexual relations. the count was about to say that it was bc shuli looked like empress ludovica but the queen intervened before the count could say it (probs bc she doesn't want to open THAT can of worms) and dismissed the trial.
