According to Yahoo Sports' Greg Wyshynski, the major stakeholders in the World Cup of Hockey--the NHL, the NHLPA and the IIHF--will be taking part in the decision-making processes regarding supplementary discipline, video replay and coaches' challenges, but to different extents. Supplementary disicipline is a tri-party issue:

NHL deputy commissioner Bill Daly tells Yahoo Sports that suspensions and fines in the World Cup of Hockey tournament will be determined by a three-person panel. The first person is a representative from the NHL’s Department of Player Safety. The second is a representative from NHL’s Department of Hockey Operations. The third is a representative from the IIHF.

Those three are the judge and jury, but there will also be an NHLPA representative “in an observer’s role,” according to Daly.

Under IIHF rules, players that are suspended in one tournament can have those suspensions carry over to other tournaments. Please recalled the knee-on-knee hit from Swedish defenseman Alex Edler on Canada’s Eric Staal, which resulted in a four-game suspension that bridged between the 2013 IIHF world championships and the 2014 Sochi Olympics.

Would suspensions in the World Cup of Hockey carry over to other international tournaments?

“Absent extraordinary circumstances, discipline would be for the tournament only with no carryover,” said Daly, who added that “in extraordinary circumstances, each organization can treat as it sees fit.”

Wyshynski continues, explaining that the NHL's situation room will handle video review, and that a combination of NHL and IIHF referees will deal with penalties and coaches' challenges.
