S4·E12 Dungaree Justice

Harm and Mac are assigned to prosecute three sailors charged with the vicious beating of a man they say raped a fellow shipmate. The rape victim, Petty Officer Lopez, tells Mac that, after an evening of drinking with her three male shipmates, she found herself alone at the bar where they ditched her as part of an initiation into their team. The next morning when she awakened in her car, she realized that she had been raped. When the shipmates heard Lopez's story, they exacted revenge on the man they thought attacked her -- the bar owner. But as Harm and Mac wear down the testimony of the three sailors, a very different story about what happened that evening begins to emerge.

This episode starts with tying up the loose end of Mac being charged in an Article 32 hearing for perjury (People vs. Mac). She is acquitted, thanks to fancy legal-speak from Harm - although she does not have to face a court-martial, she does end being sent up on an Admiral's Mast, which just might be worse.
