Dayton Hudson Corp. and Dart Group announced that they had gone to federal court in separate lawsuits over Dart's unsolicited $6.62-billion bid for the seventh-largest retailer. Dayton Hudson asked for an injunction prohibiting Dart from "acquiring, voting or attempting to acquire authorizations or proxies with respect to Dayton Hudson stock." The retailer also charged the Landover, Md. company with violating federal and state securities laws and said it was seeking an injunction to force Dart to divest itself of all Dayton Hudson stock. Dayton Hudson also sought unspecified damages in the suit, filed in U.S. District Court in Minneapolis. Meanwhile, Dart continued its offensive in the same court. A Dart affiliate, Madison Partnership, sued the retailer, seeking to force Dayton Hudson to provide the partnership with complete shareholder information. Madison claimed Dayton Hudson refused a request for the information, which Dart needs for a planned solicitation of proxies from shareholders.
