Kirk Boyd has a wide ranging litigation/trial practice that includes class actions, free speech and other civil rights, personal injury and general business litigation matters. Kirk started his practice, along with Mike Ram and Karl Olson, at the law firm Morrison & Forester and later worked with smaller plaintiffs oriented firms. He has tried cases in both Federal and State courts where he has obtained million dollar verdicts, and he has argued at every level of appellate court, including the United States Supreme Court.

As a complement to his trial and appellate practice, Kirk has remained on the cutting edge of the law academically over the past 20 years. He graduated from the University of California, Berkeley, School of Law, in 1985. Kirk returned to Berkeley Law School in 1996 where he received an LL.M writing about the enforcement of economic and social rights in courts of law. He then went on to his doctorate, receiving his J.S.D. in 2001, also from Berkeley Law, for drafting an International Bill of Rights that can be enforceable in the courts of all countries. This work went on to become a best-selling book published throughout the United States and other countries, 2048: Humanity's Agreement to Live Together, which tells about the evolution of the Universal Declaration of Human Rights into an enforceable International Bill of Rights.

Kirk is admitted to practice in California, and in the state of Hawaii. He is a member of the San Francisco Trial Lawyers Association and the Consumer Attorneys of California, and continues to work with the International Bill of Rights Project.
