Senior Attorney, Pacific Legal Foundation
Brian Hodges is a Senior Attorney at PLF’s Pacific Northwest office in Bellevue, Washington. Brian focuses his practice on defending of the right of individuals to make reasonable use of their property, free of unnecessary and oppressive regulations.
In 2013, Brian second-chaired Koontz v. St. Johns River Water Management District before the U.S. Supreme Court, a case that placed constitutional limits on the government’s common practice of demanding that landowners fund unrelated public projects in exchange for a permit approval. And in the 2008 case, Citizens’ Alliance for Property Rights v. Sims, Brian successfully challenged a Seattle-area ordinance that required all rural property owners to dedicate at least half their land as conservation areas as a mandatory condition of any new development without any showing that rural development would impact the environment.
Brian graduated from Seattle University of Law in 2001 with honors. After which, he served as a judicial clerk at the Washington State Court of Appeals, then entered private practice where he focused on appellate advocacy for several years before joining PLF in 2006.
Brian came to the liberty movement by an uncommon route: the arts. Brian played guitar and keyboards in several Seattle-area bands before eventually studying music composition and literature at the University of Washington—earning two Bachelor’s Degrees and a Master of Arts. Through that experience, he came to firmly believe that the goal of art—indeed, the goal of any creative ambition—is to maximize individual freedom and expression, tempered by personal responsibility and ownership, rather than outside oversight or arbitrary restriction. Carrying that philosophy into law school naturally led him to fight for individual rights.
Senior Attorney, Pacific Legal Foundation
Chris Kieser practices in PLF’s property rights and equality before the law practice groups.
His property rights clients include Cedar Point Nursery, which challenged a California regulation requiring them to allow union organizers to invade their private property, as well as Randall and Kimberley Pavlock, who are fighting back against Indiana’s beachfront land grab along Lake Michigan.
Under equality before the law, Chris represents coalitions of Asian-American parents challenging discriminatory admissions policies for selective K-12 schools in New York City; Montgomery County, Maryland; and Fairfax County, Virginia. He also represents a parent organization in Connecticut challenging a racial quota that prevents many Black and Hispanic students from enrolling at the state’s magnet schools.
Chris has published law review articles in the William & Mary Environmental Law Review and the Federalist Society Review. His op-eds have appeared in the New York Daily News, National Review, The Blaze, the Daily Journal, and SCOTUSblog.
Chris clerked for the Honorable Daniel A. Manion of the United States Court of Appeals for the Seventh Circuit and the Honorable Thomas D. Schroeder of the United States District Court for the Middle District of North Carolina. He holds a B.A., cum laude, from the University of Notre Dame, and graduated magna cum laude from Notre Dame Law School in 2013. At Notre Dame, he was an articles editor of the Notre Dame Law Review.
Growing up on Long Island, Chris developed a deep passion for limited government and individual liberty, arguing with his more numerous progressive classmates. This experience made him deeply skeptical that government tinkering at the expense of individual rights ever works, whether it be denying a property owner the use of his land or a student a seat at her desired school because of her race. He chose PLF because it is the national leader in litigation that furthers individual liberty.
When he’s not working, you’re likely to find Chris rooting for the Mets and Fighting Irish or debating some arcane point of law (because apparently that doesn’t happen enough at work).
Chris is currently licensed to practice in California and admitted to practice before the Supreme Court of the United States, the United States Courts of Appeal for the Second, Seventh, and Ninth Circuits, and the U.S. District Courts for the Eastern and Central Districts of California, the Northern District of Indiana, and the Northern District of Illinois.
John Sullivan has specialized in disparity studies since 1990. In that time he has served as expert witness in six challenges to racial preference programs in public contracting. He has published widely on disparity studies in law and public policy journals and in the Wall Street Journal and the Christian Science Monitor. He testified before a Congressional subcommittee on the only federal government-wide disparity study.
