Breaking: NHL files suit against NHLPA over Wideman attack on referee.

The case surrounding Calgary Flames defenseman Dennis Wideman's hit on a National Hockey League official dominated the headlines in the later stages of the 2015-2016 NHL season, and it appears the story hasn't yet reached it's conclusion.

According to multiple reports the NHL has filed a form of a lawsuit against the NHLPA in the hopes of vacating the decision that reduced Wideman's suspension to 10 games, as opposed to the original 20 handed down by the NHL. Commisioner Bill Daly confirmed the reports in a statement to TSN.

"We can confirm that the National Hockey League today filed an action in the federal district court for the Southern District of New York seeking to vacate Arbitrator James Oldham's arbitration decision reducing the League's supplementary discipline suspension to Player Dennis Wideman from 20 to 10 games. We believe that Arbitrator Oldham, in reaching his decision, exceeded his contractual authority by failing to properly apply the parties' collectively bargained standard of review."

The NHLPA has responded to the lawsuit and believes it is completely without merit and against the collectively bargained agreement.

"We are disappointed that the NHL has chosen to challenge the award of the Neutral Discipline Arbitrator (NDA) in court, as the collective bargaining agreement clearly provides that the decision of the NDA is final. We are confident this action is completely without merit and that the court will agree."

No word yet on when a decision from the courts can be expected.
