Cal. R. 3.1552
The parties may offer such evidence as is relevant and material to the dispute. An agreement to modify the rules of evidence for the trial made pursuant to the expedited jury trial statutes commencing with Code of Civil Procedure section 630.01 may be included in the consent order or agreement of the parties. To the extent feasible, the parties should stipulate to modes and methods of presentation that will expedite the process, either in the consent order or at the pretrial conference.
(Subd (a) amended effective July 1, 2016.)
Objections to evidence and motions to exclude evidence must be submitted in a timely manner. Except as provided in rule 3.1548(f), failure to raise an objection before trial does not preclude making an objection or motion to exclude at trial.
