HOUSTON - A Texas federal judge on Sept. 13 denied a motion to dismiss a class suit brought under the Telephone Consumer Protection Act (TCPA), 47 U.S.C.S. § 227, opining that when a district court has federal question jurisdiction over the claims, it does not need to conduct a choice-of-law analysis and must apply federal law to the federal cause of action (Todd C. Bank, et al. v., Spark Energy Holdings, LLC, et al., No. 11-4082, S.D. Texas; 2012 U.S. Dist. LEXIS 130531).
