Expert Witnesses


In a trial involving expert witnesses, a series of events occur according to an agreed upon schedule. In Kitzmiller, each side named six expert witnesses on March 1, 2005. On April 1, expert reports were produced by each expert. Rebuttal experts were then named, and rebuttal expert reports, if any, were filed on May 15. Depositions were scheduled between May and August.

The purpose of an expert report is to disclose the opinions of the expert, and the evidence upon which he or she will rely. This report is used by opposing counsel for preparation for depositions and trial testimony. At trial, experts are qualified to testify only about their specific topics of expertise, and their testimony is supposed to be restricted to the approximate content of the expert report.

Rebuttal of Pennock, Forrest, Alters and Padian: 2005-05-16


1. Barbara Forrest filed a supplemental expert report analyzing documents produced in a subpoena to the Foundation for Thought and Ethics, including unpublished creationist drafts of the "intelligent design" textbook Of Pandas and People.

2. During the trial in October 2005, the Discovery Institute attempted to include Meyer's expert report in a Discovery Institute amicus brief filed with the court. Because Meyer had been withdrawn from the case and his testimony would therefore not be subject to cross-examination, the judge ordered that the amicus brief be stricken. The Discovery Institute then submitted a second amicus which does not include Meyer's expert report.
