Farewell, My Turnabout / Saraba, Gyakuten (JP)
After Franziska von Karma shows up with the final evidence (Pistol, Video Tape, Bellboy's Uniform), make a save to avoid going through the Trial section again.
The Judge will ask you to WHO and WHICH evidence you want to show.
Present anything that is NOT Shelly de Killer or the Video Tape, the Judge won't be satisfied and will declare Engarde Not Guilty on the spot and you will see the bad ending afterwards.
Load back your save and when the Judge asks for your answer :
---> Present Shelly de Killer's profile
---> Present Video Tape
---> Reason : Wanted blackmail on you
