AT&T retaliated against Sprint's attempt to get corporate documents in a Department of Justice lawsuit on Wednesday through a court request that would potentially force Sprint hand over its own information. The larger carrier's motion to compel would require that Sprint hand over documents on 47 areas explaining how it planned to compete whether or not AT&T's merger with T-Mobile was approved. The request would ask for some of Sprint's most confidential information, including possible discussion of a Sprint buyout of T-Mobile should AT&T be rejected.
