During the tournament the officials have been evaluated by officiating managers including Konstantin Komissarov (IIHF) and Terry Gregson, former Head of Officiating for the National Hockey League, and six others (four IIHF, three NHL). The process by which the officiating crews are selected for the playoff round is determined by their performance in the preliminary round. For the medal games, the officials chosen were judged to deserve these assignments based on their performance in the playoff round.

“The main factor of the selection of these officials has most of all to do with their experience officiating in high-level competitions,” said Komissarov. “These include Stanley Cup playoffs, World Championship competitions, and Olympic competitions."

“Their nationalities aren’t considered as factors nor should they be, we want the best officials working the medal games,” he added. “We are fully confident that with their experience and professionalism these officials will do their job well and preserve the integrity of the game.”
