Kline & Specter has sued two California-based personal injury firms over fees related to the three firms’ work together as co-counsel in 71 cases involving injuries from the use of dental adhesive.

According to the suit, Kline & Specter alleges California firms Levin Simes and Schneider Wallace as well as Levin Simes name partner William A. Levin usurped Kline & Specter’s sole authority as settlement counsel in the cases and did not pay the firm settlement fees it was owed under their agreement.
