Glenn Pomerantz, David Dinielli Accept DOJ Assignment for AT&T, T-Mobile Case

Munger, Tolles & Olson litigation partner Glenn D. Pomerantz has resigned from the firm to join the U.S. Department of Justice as co-counsel on the government’s trial team for the AT&T Inc./T-Mobile USA Inc. merger litigation. Mr. Pomerantz will join Joseph Wayland, the Deputy Assistant Attorney General in charge of the litigation, as a lead trial attorney.

David C. Dinielli, another Munger Tolles litigation partner, is joining Mr. Pomerantz as part of the DOJ team.

A trial in the matter is scheduled to begin in mid-February 2012 and conclude in March 2012.

Mr. Pomerantz and Mr. Dinielli handle antitrust matters for numerous clients. Earlier this year, they obtained a significant result from the 9th U.S. Circuit Court of Appeals in an antitrust case involving all of the major television programmers and distributors. At the Ninth Circuit, Mr. Pomerantz presented the oral argument, and the court ruled in favor of Mr. Pomerantz’s clients in finding that agreements requiring the “tiering” or bundling of cable channels do not constitute Sherman Act violations.

Mr. Pomerantz also represents clients in copyright and other matters. Earlier this year, he represented the four major record companies in a copyright action in New York federal court against LimeWire, the largest peer-to-peer service. After obtaining an injunction that shut down the service, he secured a $105 million settlement in the midst of the damages trial. Mr. Pomerantz also successfully represented the six major motion picture studios this year in obtaining a preliminary injunction shutting down the Zediva service.

Mr. Dinielli’s practice includes antitrust litigation and counseling, securities litigation, shareholder litigation, class action defense, trademark and licensing litigation as well as LGBT litigation. In the last year, he has represented Activision, the largest video game publisher, in a Supreme Court case holding unconstitutional California’s law banning the sale of “violent video games" to minors. He also has worked extensively with the National Center for Lesbian Rights, on initiatives and litigation involving the rights of youths and same-sex couples.
