Rugby Football Union, The Laws of the game of Football as played by the Rugby Football Union (1883)
“ In case of a maul in goal, those players only who are touching the ball with their hands when it crosses the goal line, may continue in the maul in goal, and when a player has once released his hold of the ball after it is inside the goal line, he may not again join in the maul, and if he attempts to do so, may be dragged out by the opposite side. But if a player when running in is tackled inside the goal-line, then only the player who first tackled him, or if two or more tackle him simultaneously, they only may join in the maul. ”
