Banks across the U.S. “have therefore been forced to bear the damages” associated with T-Mobile’s “actions and omissions,” it said. “These financial institutions are completely without fault, but are held responsible for these damages because of the strict liability provisions of Reg E,” said the complaint. Based on its allegations, the complaint puts “substantially more” than $5 million “in controversy in this action,” said T-Mobile’s notice of removal (docket 2:22-cv-13159). T-Mobile didn't comment Tuesday. An unrelated Dec. 21 class action alleged T-Mobile failed to protect customers' information in a SIM swap fraud (see 2212270024). That complaint alleged T-Mobile’s “gross negligence” in protecting consumers’ data, plus its “negligent hiring and supervision” of employees responsible for safeguarding that information, resulted in the loss of millions of dollars for plaintiffs in the class action.
