The Japan baseball players association filed with the Tokyo District Court on Friday for an injunction against the planned merger between the Orix BlueWave and the Osaka Kintetsu Buffaloes.
The move -- which occurred on the same day that the two clubs finalized their basic merger agreement of Aug. 10 -- came after baseball officials turned down a series of demands by the association, including a call for establishing a special committee to handle contractual issues for the players affected by the merger.
The association, a labor union, has been demanding that not only club management but also players' representatives take part in any decision-making processes of such a committee.
