Linguist and law school professor, Peter Tiersma, wrote an article titled "Instructions to jurors: Redrafting California’s jury instructions" in "The Routledge Handbook of Forensic Linguistics" in 2010. He outlines the history of legal trials and how pattern jury instructions were developed in order to create an atmosphere in which jurors are given pertinent information to a case in order to determine factual evidence and guilt of an accused individual. Throughout the 1930s and 1940s in California, a panel comprising judges and lawyers drafted pattern jury instructions.
