Plaintiffs law firm Sheller P.C. is looking to get paid for its work as part of a consortium of law firms representing claimants seeking reimbursement for damages from the explosion of BP’s Deepwater Horizon drilling rig and the resulting oil spill.

Sheller P.C. has sued in Philadelphia Common Pleas Court two Florida law firms that headed up the consortium known as Gulf Action Spill Plaintiffs, or GASP. The firm claims that Howard & Associates as head of the consortium and Lyons & Farrar as the office where all claims were processed have not paid Sheller P.C. any fees for the work it did for the consortium and have stopped keeping Sheller P.C. attorneys updated on the claims and several class actions GASP has filed, according to the complaint.
