His current work focuses on property rights and economic liberty cases in federal and state courts. In property rights, Bullock has been involved in many cases challenging the use of eminent domain for private development. He argued the landmark case, Kelo v. City of New London, one of the most controversial and widely discussed U.S. Supreme Court decisions in decades. He was co-counsel in the first state supreme court victory after Kelo, where the Supreme Court of Ohio unanimously struck down the use of eminent domain for private development. Some of his other successes in this area include spearheading the litigation that saved a beachfront neighborhood in Long Branch, New Jersey, a small record label in Nashville, Tennessee, and the homes of the Archie family in Canton, Mississippi.

Among his work on other constitutional issues, Bullock has represented the monks of St. Joseph Abbey in their challenge to a Louisiana law that prevented them from selling hand-made wooden caskets. That case led to a landmark decision by the 5th Circuit Court of Appeals protecting economic liberty. He served as lead counsel in the First Amendment challenge to a federal agency’s campaign against investment newsletters, computer software and websites, establishing an early precedent extending free speech guarantees to Internet and software publishers. He also has led successful lawsuits against rental inspection laws on behalf of tenants and defending efforts to open up taxi markets to more competition.

He is co-author of Policing for Profit, documenting forfeiture abuse at all levels of government. He has published articles in the New York Times and Wall Street Journal, and he has appeared on 0 Minutes, ABC Nightly News, and National Public Radio, among many other publications and broadcasts.
