How would Harry even get to the trial in the first place? Dumbledore won’t let him leave Hogwarts, and if he did, why should the Wizengamot admit him to the proceedings unless e.g. Dumbledore requested it? And why would D. do that unless he expected Harry to succeed in helping Hermione escape? But if D. wanted Hermione to escape illegally (possible but unlikely IMO), he could surely arrange that himself without Harry’s help and presence. (Maybe he’d borrow the cloak...)
“Harry had used up all six hours from his Time-Turner, and there were still no clues, and he had to go to sleep now if he wanted to be functional at Hermione’s trial the next day.”
I assumed this means Harry will be at trial. Probably as a witness?

He could only be a character witness, at most. Not very relevant to the trial at hand.
Maybe Dumbledore will just bring him in as a spectator, and wouldn’t have to ask anyone’s permission. We don’t know what the rules for that are.
He is a member of a noble house. He is probably entitled to observe, even if his age prevents him from taking his seat.
