The National Hockey League (NHL) and its players can’t seem to come to an agreement. For months, the two parties have been embroiled in labor disputes with no success. On Friday, they landed in court with the NHL filing a class action suit against the NHL Players’ Association (NHLPA), the players’ union.

In addition to filing unfair labor practice claims against the players’ union, the NHL also asked the court to address whether the player lockout was legal.

According to Thomson Reuters, the suit may be an attempt on the part of the NHL to stop the players from voting on whether they should be represented by the union.

“Today, in response to information indicating that NHL players have or will be asked to vote to authorize the National Hockey League Players’ Association’s executive board to proceed to ‘disclaim interest’ in continuing to represent the players in collective bargaining, the National Hockey League filed a class action complaint in Federal Court in New York seeking a declaration confirming the ongoing legality of the lockout,” the NHL said in a statement.

The union says the suit is meritless.

Last year, the National Basketball Association was working through its labor disputes with players.
