Yes, I realize that Alethea. For instance, let's say, both side agree to agree that the murder weapon was a crossbow. It will therefore not be necessary for prosecutors to produce endless testimony about the purchase, size, capacity of the crossbow and the murderers skills in that respect and the defence won't have to produce matching testimony to counter. What I meant was the Agreed Statement of Facts promotes time saving efficiency because each side reaches agreement on evidence or events that need not be introduced at trial.
Statement of Facts gets read to the jury/court at the beginning of the trial. It clarifies to the jury/court certain facts which essentially helps with deliberating as they do not have to question or deliberate on those facts. This can be helpful to both sides for various reasons, according to my lawyer friend.Sorry if this has already been said but I haven't read it or may have missed it.
