41.2.4. Waving a red flag or hand for an improper re-entry of an excluded player or improper entry of a substitute.

41.3. Each goal line judge shall be provided by the Organising Committee with a supply of balls and when the original ball has gone outside the field of play, they shall immediately throw a new ball to the goalkeeper (for a goal throw), to the nearest player of the attacking team (for a corner throw), or as otherwise directed by the referee.
Each goal line judge shall be provided by the organising committee with a supply of balls. When the ball has gone outside the field of play they shall throw a new ball to the goal keeper (for a goal throw), or to the nearest player of the attacking team (for a corner throw) as directed by the referee.
Reason: to prevent multiple balls on the playing area, goal line judges are requested to throw a ball into the playing area only when directed by the referee.
The Goal Line Judge must ensure that substitutes do not interfere with play. If in their opinion a substitute does interfere, or remains in the Subs No Waiting Area (see Diagram L&T 1) directly behind the goal, then they should draw this to the attention of the referee who will then deal with the matter with at least a Green Card.
The Goal Line Judge must ensure a player being substituted has entirely left the playing area with the whole of their kayak before the substituting player starts to enter the playing area.
