Gillette sued to block Revlon’s takeover bid.

Gillette has not formally responded to Revlon’s $65-per-share tender offer, but it asked a federal court in Boston to block Revlon, its affiliated companies and Revlon Chairman Ronald O. Perelman from buying any more Gillette stock while it considers the proposal. Revlon has sued to overturn Gillette’s “poison pill” plan that would allow shareholders to buy stock of the acquiring company at half-price as the result of a hostile takeover.
