Reuben Camper Cahn is one of the most exceptional lawyers of his generation.  In addition to trying more than 100 cases to jury verdict, Mr. Cahn has argued twice before the United States Supreme Court (in 2011 and 2018), a combination that is all but unknown.  He has also argued extensively before the 9th and 11th Circuits.

After earning his A.B at Stanford University with honors, Mr. Cahn graduated from Yale Law School, where he was an editor of the Yale Law Journal.  Following graduation he clerked for the Honorable Lawrence W. Pierce of the United States Court of Appeals for the Second Circuit.

Mr. Cahn began his career in New York at Wachtell, Lipton, Rosen & Katz, and then Paul, Weiss, Rifkind, Wharton & Garrison, where he worked on securities litigation and international arbitration for a combined four years.

Realizing he wanted to try cases and serve the underrepresented, Mr. Cahn then embarked on a career as an assistant public defender, where he distinguished himself both as an advocate and as a leader in the federal defender community.  He was appointed by the Chief Justice of the United States Supreme Court to review the Criminal Justice Act; was the defender representative to the Judicial Conference’s Defender Services Committee; chaired the Magistrate Judges Selection Committee of the Southern District of Florida; and held numerous other positions of distinction and responsibility.  Mr. Cahn has won multiple awards for his advocacy.

Mr. Cahn rose to become the Chief Assistant Federal Public Defender in the Southern District of Florida, and after relocating to California, was the Executive Director of Defenders, Inc. (Federal Public Defenders), in San Diego for 13 years.  In that role he managed an office of over 60 attorneys and 140 employees, with a budget of $26 million.  At the same time he continued to try cases and argue appeals, including United States v. Jared Loughner (9th Circuit, 2017), Tapia v. United States, 564 U.S. 319 (Supreme Court, 2011), and United States v. Sanchez-Gomez, 584 U.S. ___ (Supreme Court, 2018).

Mr. Cahn has defended a wide range of matters, involving tax, public corruption, fraud, money laundering, RICO, Continuing Criminal Enterprise prosecutions and virtually every other type of white collar case.  He has been lead counsel in federal capital cases, including one that resulted in complete acquittal and another that ended with a unanimous life sentence.  Mr. Cahn has been appointed “counsel learned in the law” by federal judges in over 15 capital trials.

Additionally, he represented alleged enemy combatants confined at Guantanamo Bay Naval Base and in litigation before the District of Columbia Court and the D.C. Circuit Court of Appeals.  His team was one of the very few to complete a contested evidentiary hearing under the extraordinary rules that govern these cases.  Mr. Cahn holds a Top Secret/SCI Clearance.

At Keller/Anderle Mr. Cahn focuses on commercial litigation, white collar criminal defense, and appeals.  He brings to his KA clients the energy and experience honed in countless jury trials, and in arguments before federal appellate courts and the highest court in the land.
