International union committed unfair labour practice by imposing trusteeship partly to penalize locals for filing complaint.
The complainants, several local unions and their business representatives, alleged that the respondent International union committed an unfair labour practice by placing the Ontario District Council under trusteeship.
The complainants argued the trusteeship was a reprisal for their filing of a previous section 89 complaint (the 'EPSCA complaint') against the International.
The Board found that while there were legitimate concerns about the Council's financial practices, the International's decision to impose the trusteeship was motivated at least in part by a desire to penalize the complainants and impede their prosecution of the EPSCA complaint.
The Board held this violated section 80(2) of the Labour Relations Act and ordered the International to cease exercising control in a manner that would interfere with the EPSCA complaint.
