The Justice Department’s case seeking to block AT&T’s $39 billion acquisition of Deutsche Telekom’s T-Mobile is rocketing toward a Feb. 13 trial date. AT&T has everything riding on either a win at trial or a settlement that satisfies DOJ’s concerns about the combined entity’s dominance in nationwide wireless markets; as On the Case has reported, AT&T withdrew its application for Federal Communications Commission approval of the merger after the FCC announced it wanted an administrative law judge to consider the agency’s problems with the proposed deal. AT&T and T-Mobile are apparently betting that they’ll be able to come back to the FCC with a stronger case after they’ve appeased (or vanquished) the Justice Department.
