Philadelphia lawyer Bruce Chasan, who is suing the founder of a fast-growing litigation boutique over a purported fee-sharing settlement, is arguing that the boutique backed out of the settlement so it could fund other cases.

In a memo filed Feb. 8, Chasan argued that the ex-client in question, former pro footballer and wrestler Lenwood Hamilton, did not need to sign off on his agreement with litigator John Pierce of Pierce Bainbridge Beck Price & Hecht for a previously discussed $160,000 settlement to be binding. Chasan alleged in his latest filing that Pierce derailed the settlement so his firm could fund other cases against video game makers.
