Dallas lawyer Russell DePalma missed a deadline to file an appeal, which “forced” an insurance company to pay a “highly inflated” $2.275 million to settle litigation, the insurer and a company it insured allege in a lawsuit filed in Harris County.

National American Insurance Co. (NAICO) and Oklahoma-based Okie Foundation Drilling Co. Inc. seek more than $1 million in damages and fee forfeitures from DePalma and two firms where he formerly worked — FisherBroyles and Greenberg Traurig. DePalma, a former partner in FisherBroyles and former counsel with Greenberg Traurig, is now senior counsel at Shore Chan DePumpo of Dallas.
