  • Hon. Kim McLane Wardlaw, U.S. Court of Appeals for the Ninth Circuit


  • California

Michael Behrens has achieved significant results for clients in a wide array of complex commercial litigation cases. His practice spans many areas of law, including contracts, professional malpractice, toxic torts, corporate executive employment disputes, defamation, health care fraud, RICO, and labor unions. Mr. Behrens handles cases in state and federal courts, at both the trial and appellate level, and he regularly represents clients in arbitrations as well as in administrative and regulatory proceedings. Mr. Behrens also frequently represents governments and universities and advises institutions facing regulatory action, drawing on his deep experience conducting complex internal investigations.

The son of a Japanese-American woman born in an internment camp, Mr. Behrens maintains an extensive pro bono practice focused on immigration issues. In 2014, Mr. Behrens obtained a landmark constitutional holding from the U.S. Court of Appeals for the Ninth Circuit. He successfully argued that the Immigration and Naturalization Service had violated his pro bono client’s constitutional due process rights by mishandling the client’s mother’s 1985 naturalization petition, depriving him of automatic U.S. citizenship. In the resulting opinion, Brown v. Holder, 763 F.3d 1141 (9th Cir. 2014), the court held for the first time that a constitutional right exists to apply for U.S. citizenship. Judge Tallman’s concurrence called the ruling “expansive” and “novel.”

While in law school, Mr. Behrens served as articles editor for the UCLA Law Review and was named a Michael T. Masin Scholar.
