The Litigator of the Week crown this week goes to Kirkland & Ellis partners Kevin Van Wart and Brad Weidenhammer for their win on behalf of Teva Pharmaceutical Industries in a suit against the nation’s largest health insurance company, United Healthcare.

Teva sued United in 2016 in U.S. District Court for the Eastern District of Pennsylvania after United tried to walk away from a $125 million settlement agreement signed by United’s outside lawyers. The resulting litigation—which turned in part on a he-said-she-said dispute with a client about authority to sign a settlement agreement—should scare every lawyer.
