WIPA filed the suit in the High Court of Justice of Trinidad and Tobago and seeks damages for WIPA and its members.
The claim is related to the issuance of No Objection Certificates issued to players by WICB, which require players to fulfill international duties for the West Indies team if selected.
The WICB said Sunday its legal team is studying the documents and a further statement will be made at the appropriate time. The Board also added that it regrets that WIPA has taken this action in the middle of the MOU/CBA negotiations.
The two bodies have been locked in a bitter feud for a long time over the issue of contracts and the lawsuit is the latest twist in their ongoing feud.
