A federal magistrate judge ended a six-month discovery dispute Friday in an antitrust class action involving a T-Mobile merger, rejecting the plaintiffs' request to add three of the mobile tech company's in-house counsel to a custodian list.

On Friday, U.S. District Magistrate Judge Jeffrey Cole for the Northern District of Illinois denied the plaintiffs' motion to compel T-Mobile to use its proposed discovery list in the case captioned Anthony Dale v. Deutsche Telekom AG. Out of a list of 50 individuals, the plaintiffs asked that T-Mobile's in-house counsel be included to provide information regarding their oversight of the T-Mobile merger with Sprint. The attorneys at issue included: David Miller, former executive vice president and general counsel; Mark Nelson, executive vice president and general counsel; and Kathleen Ham, former senior vice president, government affairs, the memorandum opinion and order said.
