1. To reduce the incidence of injuries and concussions during warm-up, Volleyball Canada has developed a warm-up protocol. This protocol is to be followed by all teams during the official warm-up. For teams that do not follow the warm-up protocol, the referees will note incidents of non-compliance on the scoresheet. The league, PTA, or Volleyball Canada (depending on the event) will determine the appropriate sanction. (see Rule 7.2.4)
2. The line-up sheet must be checked by the second referee and scorer before the scorer writes the line-up data on the score sheet. He/she must check if the players’ numbers listed on the line-up sheet correspond to the players’ numbers listed on the score sheet. If not, the line-up sheet must be corrected and another one requested by the second referee. In the new line-up sheet, any modification may be done solely in the position, where the number(s) was / were not correct. The line-up sheet must be kept by the second referee in his/her pocket in order to be able to verify the actual line-up of teams if it is necessary or required unless the e-score sheet and second referee post tablet is in use.
3. At the end of each set, the second referee immediately asks the coaches for the line-up sheet for the next set, to avoid prolonging the three-minute interval between sets.
If a coach systematically delays the resumption of the game by not providing the line-up sheet on time, the first referee must give this team an appropriate delay sanction. This also applies if the team fails to provide the information electronically via the tablet.
4. If a positional fault is committed, after the hand signal for the positional fault, the referee must indicate the two players. If the players at fault do not rectify their positions themselves, the referees must rectify the position of the players and then the next rally should be started.
If the game captain requests more information on the fault, the second referee should take out from his/her pocket the line-up sheet and show the game captain the players who committed the positional fault.
5. To try to reduce the number of positional calls by referees, and to reflect the current reality of player switching positions, second referees in particular need only whistle if a back row player is completely in front of the corresponding front row player at the service hit. Feet on the ground determine the position.
6. For simplicity in judging side-to-side overlap, referees need only ensure that the middle player is not completely nearer the side-line than the neighboring players in the same row at the service hit.
