The video umpire can advise on whether the ball crossed the line there was a violation. Ordinarily, teams are not allowed to make such a request or to press the match umpire to do so. On a trial basis, the 2009 Men's Champions Trophy allows for "team referral" by each team captain, to query a goal, penalty stroke, or penalty corner decision. The team retains the right to a referral if its previous referrals were upheld. Ice hockey The video goal judge reviews replays of disputed goals. As the referee does not have access to television monitors, the video goal judge's decision in disputed goals is taken as final. In the NHL, goals may only be reviewed in the following situations: puck crossing the goal line completely and before time expired, puck in the net prior to goal frame being dislodged, puck being directed into the net by hand or foot, puck deflected into the net off an official, and puck deflected into the goal by a high stick (stick above the goal) by an attacking player. The video goal judge also reviews replays to establish the correct time on the game clock. All NHL goals and time remaining on the game clock are subject to review, and although most arenas have a video goal judge, often officials in the Situation Room (also known as the "War Room") at the NHL office in Toronto make the final decision. Review challenges Beginning in the 2015-16 NHL season, instant replay reviews have been expanded to include a coach's challenge. Each coach receives one challenge per game, which requires the use of a timeout. Coaches may only challenge over situations whether the goal should have been disallowed because of goaltender interference or an offside, or whether a goal disallowed because of goaltender interference should be allowed instead. The challenging team retains its timeout and its challenge after every goaltender interference call that has been overturned. There are two situations that happen when a challenge is upheld: If an offside review is upheld, the challenging team receives a minor penalty for delay of game. If a goaltender interference review is upheld, the challenging team loses its timeout. Challenges are not allowed during the final minute of regulation, as well as at any point during overtime. In this situation, officials in the Situation Room reviews all instances where the puck entered the net, and then
