Your defense attorney may now make a motion for direct verdict. He points out that the case has insufficient evidence to continue to a jury trial. In response, plaintiff's attorney has the burden to prove that he has sufficient evidence to continue the case. Summation comes after all evidence has been presented. It usually takes about half an hour.
Summations are arguments made by the plaintiff's attorney and the defense attorney to the jury.
After the arguments, the judge will instruct the jury that it is the final arbiter of the case. It's the jury s prerogative to decide on the truth of the facts, the liability of the defendants if any, and eventual damages to be estimated. If the defendant is guilty, the jury will have to decide on the amount of the damages. Then the jury retires to discuss the case. That's called deliberation.
