TOKYO, Oct 29 (Reuters) - A court on Friday rejected a request for an interim injunction from Tokyo Kikai Seisakusho Ltd’s biggest shareholder that would have prevented the company from issuing a poison pill - a closely watched ruling with implications for future hostile bids in Japan. The court rejected injunction request from Asia Development Capital, according to a copy of the ruling seen by Reuters. Tokyo Kikai, Japan’s biggest manufacturer of printing presses for newspapers, is seeking to issue new shares that would dilute Asia Development Capital’s 40% stake - a holding that the investment firm built up rapidly in a matter of weeks.
