Section 202.37 - Scheduling Witnesses
At the commencement of the trial or at such time as the court may direct, each party shall identify in writing for the court the witnesses it intends to call, the order in which they shall testify and the estimated length of their testimony, and shall provide a copy of such witness list to opposing counsel. Counsel shall separately identify for the court only a list of the witnesses who may be called solely for rebuttal or with regard to credibility. The court may permit for good cause shown and in the absence of substantial prejudice, a party to call a witness to testify who was not identified on the witness list submitted by that party. The estimates of the length of testimony and the order of witnesses provided by counsel are advisory only, and the court may permit witnesses to be called in a different order and may permit further testimony from a witness notwithstanding that the time estimate for such witness has been exceeded.
