Thank you, BillJ!
I realize why I didn't remember, bluster doesn't impress me, and that's what this is. Anyone that interprets those statements as legitimate legal power to imprison someone is a fool. It was a threat and nothing more. He could have brought charges against him once they reached starbase and a trial may have occured. Depending on the outcome of the trial, he may be sentenced to a penal colony, that is the meaning of the threat. He has authority to bring charges.
