A Team Built for the Appellate Moment
A deep bench of former federal clerks means the attorneys arguing your appeal have experience working for the judicial system. We've built first-in-nation decisions that changed how courts analyze class certification.
The Firm Called In After Certification
Watstein Terepka regularly substitutes in as lead defense counsel mid-litigation, including in already-certified class actions. In one certified TCPA matter with $10B+ in exposure, we were retained after certification and secured a rare Rule 23(f) appeal and stay from the Fourth Circuit. Every certification in the firm's history came in a case taken over from other counsel — two have since been vacated.
The Right Firm for the Highest-Stakes Defense.
We represent companies facing class exposure that can define — or end — a business. If the stakes are real, so is our commitment.
