The baseball players association said Thursday it plans to seek a court injunction as early as Friday against the planned merger between the Orix BlueWave and Kintetsu Buffaloes.

The association, a labor union, decided to take legal action after baseball officials turned down a series of its demands including a call for establishing a special committee to handle contractual issues for the players involved in the merger.

The association has been demanding that not only club management but players' representatives play a part in decision-making processes of such a committee.
