Proposition 8 in California
In 2010 Michael Lamb was to testify in the Perry v. Schwarzenegger trial which challenged California Proposition 8 as being unconstitutional. Lamb testified that children do not require a male and a female parent to have a stable and healthy life growing up. Lamb stressed that childhood adjustment relied more on the relationships between the parents and the relationships the child has with their parents. While under question by lawyer David H. Thompson, who worked for the Proposition 8 campaign, Lamb had to admit that he was a member of the ACLU, the National Organization for Women, the NAACP, Amnesty International and the Nature Conservancy. Thompson called Lamb a "committed liberal." According to the United States District Court for the Northern District of California as the education and experience of each expert show, plaintiffs' experts were amply qualified to offer opinion testimony on the subjects identified. Moreover, the experts' demeanor and responsiveness showed their comfort with the subjects of their expertise. For those reasons, the court finds that each of plaintiffs' proffered experts offered credible opinion testimony on the subjects identified.
According to trial court in Howard v. Arkansas case in 2004, of the eight expert witnesses testifying at trial, "[t]he most outstanding of the expert witnesses was Dr. Michael Lamb." The trial court explained: "Without a single note to refer to and without any hint of animus or bias, for or against any of the parties, Dr. Lamb succinctly provided full and complete responses to every single question put to him by all counsel and was very frank in responding to inquiries from the court. Of all of the trials in which the court has participated, whether as a member of the bench or of the bar, Dr. Lamb may have been the best example of what an expert witness is supposed to do in a trial, simply provide data to the trier of fact so that the trier of fact can make an informed, impartial decision."
