Our Litigator of the Week is Quinn Emanuel Urquhart & Sullivan’s Michael Lyle, who notched an emphatic win on behalf of Express Scripts after four years of litigation in U.S. District Court for the Eastern District of Missouri.

Lyle’s client faced a $120 million breach of contract suit by compounding pharmacy HM, which was represented by Boies Schiller Flexner. Not only did Lyle, who serves as co-managing partner of Quinn Emanuel’s Washington, D.C. office, lead a team in defeating the breach of contract claim, he also won a $20 million counter-claim, plus a nice chunk of the defense’s legal fees and costs.
