SCORING A GOAL:
a) A goal is scored when the whole ball has passed completely over the goal-line between the goal-posts and under the cross-bar, the ball, within the circle, having been hit by, or having glanced off, the stick of an attacker, except as specially provided for in Rule 15 (g) and Rule 16. It is immaterial if the ball subsequently touch, or be played by one or more defenders. If, during the game, the goal-posts and/or the cross-bar become displaced, and the ball pass completely over the goal-line at a point which, in the umpire’s opinion, be between where the goal-posts and/or under where the cross-bar, respectively, should have been, a goal is scored
b) The team scoring the greater number of goals shall be the winner.
The ball must be inside the circle when hit by an attacker (although he himself may be outside). If it is within the circle and then touches the stick or persons of a defender or defenders before crossing the goal - line between the posts, a goal is scored.
