Offside Rules:
11.2 BEING PUT ONSIDE BY THE ACTION OF A TEAM-MATE
In general play, there are three ways by which an offside player can be put onside by actions of that player or of team mates:
(a) Action by the player. When the offside player runs behind the team-mate who last kicked, touched or carried the ball, the player is put onside.
(b) Action by the ball carrier. When a team-mate carrying the ball runs in front of the offside player, that player is put onside.
(c) Action by the kicker or other onside player. When the kicker, or team-mate who was level with or behind the kicker when (or after) the ball was kicked, runs in front of the offside player, the player is put onside. When running forward, the team-mate may be in touch or touch-in-goal, but that team-mate must return to the playing area to put the player onside.
11.3 BEING PUT ONSIDE BY OPPONENTS
In general play, there are three ways by which an offside player can be put onside by an action of the opposing team. These three ways do not apply to a player who is offside under the 10-Metre Law.
(a) Runs 5 metres with ball. When an opponent carrying the ball runs 5 metres, the offside player is put onside.
(b) Kicks or passes. When an opponent kicks or passes the ball, the offside player is put onside.
(c) Intentionally touches ball. When an opponent intentionally touches the ball but does not catch it, the offside player is put onside
11.4 OFFSIDE UNDER THE 10-METRE LAW
(a) When a team-mate of an offside player has kicked ahead, the offside player is considered to be taking part in the game if the player is in front of an imaginary line across the field which is 10 metres from the opponent waiting to play the ball, or from where the ball lands or may land. The offside player must immediately move behind the imaginary 10-metre line or the kicker if this is closer than 10 metres. While moving away, the player must not obstruct an opponent.
Sanction: Penalty kick
(b) While moving away, the offside player cannot be put onside by any action of the opposing team. However, before the player has moved the full 10 metres, the player can be put onside by any onside team-mate who runs in front of the player.
(c) When a player who is offside under the 10-Metre Law charges an opponent waiting to catch the ball, the referee blows the whistle at once and the offside player is penalised. Delay may prove dangerous to the opponent.
Sanction: Penalty kick
(d) When a player who is offside under the 10-metre Law plays the ball which has been misfielded by an opponent, the offside player is penalised.
Sanction: Penalty kick
(e) The 10-metre Law is not altered by the fact that the ball has hit a goal post or a crossbar. What matters is where the ball lands. An offside player must not be in front of the imaginary 10-metre line across the field.
Sanction: Penalty kick
(f) The 10-metre Law does not apply when a player kicks the ball, and an opponent charges down the kick, and a team-mate of the kicker who was in front of the imaginary 10-metre line across the field then plays the ball. The opponent was not 'waiting to play the ball' and the team-mate is onside. The 10-metre Law applies if the ball touches or is played by an opponent but is not charged down.
Sanction: When a player is penalised for being offside in general play, the opposing team chooses either a penalty kick at the place of infringement or a scrum at the place where the offending team last played the ball. If it was last played in that team’s in-goal, the scrum is formed 5 metres from the goal line in line with where it was played.
(g) If more than one player is offside and moving forward after a team-mate has kicked ahead, the place of infringement is the position of the offside player closest to an opponent waiting for the ball, or closest to where the ball lands.
