Jennifer Haines (Rebecca De Mornay) is having dinner with her friend, Moe (Jack Warden). He fills her plate with spaghetti and sits down with the serving dish. His plate is clearly empty. In the next two shots, he has a full plate of food.
At 01:24:20, at the end of the trial when Moe lives the courtroom Jennifer's coat is visible on the first chairs behind the defense bench, neatly folded and resting against the back rest. Seconds later, when she picks it up, it is just lying on the seat of the chair.
Before the climatic fall from the upper level, there is an obvious addition of footrests that have been added to the side of the balcony to serve as support for the stunt woman before she falls to the ground.
