A federal judge in Connecticut has denied a motion to certify a class action against Cigna Health Insurance, citing lack of evidence of commonality and predominance.

U.S. District Judge Kari A. Dooley for the District of Connecticut determined in a July 6 opinion that the plaintiffs' bid for class certification, over allegations that Cigna violated ERISA, arising from Cigna's third-party vendor CareCentrix in securing and providing medical benefits, failed under Rules 23(a) and 23(b).
