Less than two weeks after an Illinois appellate court condemned lawyer Christopher Bandas for being a “serial objector” and for the tactics he used while opposing a class action settlement, Bandas has leveled allegations against the prominent plaintiffs class action firm Edelson, describing it as one of “the most notorious and prolific serial class action litigators” in the country and accusing it of conspiring and committing fraud.

The allegations by Bandas, of the Corpus Christi, Texas-based Bandas Law Firm, are included in a countersuit he filed against Edelson on Monday in Chicago federal court. The filing responds to an ongoing lawsuit in which Edelson accused Bandas and some of his associates of making a living by extorting payments from plaintiffs lawyers who negotiate class action settlements.
