A federal judge in Newark has denied a motion to dismiss a suit accusing underwriters at Lloyd’s of London of conspiring to increase revenue and profits by concealing a lack of competition for its U.S. insurance customers.

U.S. District Judge Claire Cecchi denied the motion to dismiss by 28 insurance syndicates affiliated with Lloyd’s, finding that the plaintiffs adequately pleaded elements of racketeering, conspiracy and unjust enrichment.
