Tobias Loss-Eaton

Practice Areas

TOBIAS LOSS-EATON represents clients in civil and criminal litigation dealing with a range of difficult regulatory, statutory, and constitutional issues. As an appellate litigator, he has extensive experience challenging and defending state and federal agency actions and regulations, including in the energy, trade, securities, and healthcare sectors. He has also litigated important cases on criminal law and sentencing, including in the Supreme Court. And he is a member of Sidley’s top-ranked transportation practice, representing the nation’s largest railroads in many cases involving contractual disputes, challenges to regulatory action, federal preemption of state law, and the proper interpretation of the Federal Employers Liability Act.

Tobias prides himself on clearly and persuasively explaining complex legal issues to busy generalist judges, at the trial level or on appeal. One prominent legal writing expert ranked Tobias’s Supreme Court briefs as better than the typical work product of “elite” Supreme Court advocates. Tobias has written or coauthored over 120 briefs in state and federal appellate courts, including 53 briefs in the Supreme Court.

Tobias served as a law clerk to Judge Norman H. Stahl of the U.S. Court of Appeals for the First Circuit and Judge Henry H. Kennedy, Jr. of the U.S. District Court for the District of Columbia. He earned his J.D., cum laude, from Harvard Law School, where he was a notes editor of the Harvard Law Review.
