Definition of Closing Arguments
A closing argument is the summation of a lawyer's arguments at the conclusion of a trial. The closing argument does not provide new evidence. The plaintiff's lawyer generally presents their closing arguments first by commenting on the evidence provided and how it proves their case. The defense follows answering questions made by the plaintiff or the government. They will talk about the defects of the state's case and talk about the facts of the case which are favorable to their client. The defense may choose not to make a closing argument.
The plaintiff or the prosecution has a final chance to provide another argument, called the rebuttal, because they have the burden of proof to prove their case to the judge or jury.
