The Massachusetts Appeals Court reversed a lower court’s ruling ordering a third-party defendant in an injury case to pay $237.000 in attorney fees to the direct defendant, holding that the judge misapplied the “in for one, in for all” rule outside the context of an insurance coverage dispute.

That rule requires an insurer to defend all claims in a complaint brought against an insured if at least one claim falls within the scope of the insurer’s duty to defend.
