The principle of advantage to the non-offending team is to apply at all times, providing some advantage is readily obvious. Once a team is given the advantage that team does not necessarily forfeit the right to other action as described in these rules.
Players should at all times play in accordance with the rules of Touch and allow the referee to interpret the advantage.
Players who use unnecessary force or whose actions unfairly prevent any other player from gaining an advantage will be liable to penalty.
A referee awards a touchdown. Lines-person reports a player from the team who was just scored against. The referee exercises discretion re disciplinary matters and sends the reported player off for a period of time. How is the match restarted?
Because the touchdown was awarded (and the player sent off) the game is recommenced with a tap to the team who was scored against at the centre of the halfway mark.
If the referee warns the defending team they are offside, what guide can be used to determine if advantage is gained?
It can be generally accepted that the advantage has been gained once the attacking team has passed the five (5) metres defensive line (for the Rollball) or the ten (10) metres line for the tap.
If the advantage is lost (say dropped ball, forward pass) after the attacking team has crossed the relevant advantage line can the referee go back and penalise the offending player?
No! Once the advantage line has been reached the referee must allow play to continue.
