The Department of Justice does not have any objections to the planned merger between Deutsche Telekom's T-Mobile USA and MetroPCS. The two companies announced intentions to merge in October of last year, but the deal requires regulatory approval and approval from shareholders.

"Deutsche Telekom has reached an important staging post at the approval process of the merger of its subsidiary T-Mobile USA and MetroPCS," Deutsche Telekom said on Wednesday. Still, the merger will need a green light from the Federal Communications Commission and approval from shareholders of MetroPCS. The approval vote is currently scheduled for March 28. Unfortunately, several large shareholders, including a hedge fund with a 2.3 percent share in the company, are already expressing concern with the possible merger.

So while the deal is one step closer to completion, there are still a few other pieces that need to fall into place before it's finalized.
