Yaakov Roth's goal is to strategically develop and effectively present the key legal arguments that will secure victory for clients through appellate advocacy and dispositive motions. He has represented clients in high-profile Supreme Court cases, argued appeals in the federal Courts of Appeals, and prepared motions to dismiss and for summary judgment across a range of substantive areas.
Yaakov's most recent Supreme Court experience includes vindicating former Virginia Gov. Bob McDonnell from political corruption charges, narrowing the geographic scope of private civil RICO lawsuits, and pursuing a major challenge to the Affordable Care Act from inception through high court review. At the appellate level, Yaakov's oral advocacy has included pressing a First Amendment challenge to an Ohio law prohibiting "false" campaign statements, seeking disclosure of a Justice Department policy manual concerning criminal discovery, and protecting the religious freedom rights of Death Row inmates. He has successfully defended his clients against defamation, antitrust, Title VII, and ERISA claims — including nationwide class actions — and pursued a host of challenges to federal, state, and local regulations. His ERISA experience also includes a series of withdrawal liability arbitrations and related litigation.
