Lets stop calling it a Maul as it wasn't, it would require a player from either team.No. Cranbrook never joined the maul BUT ball was never passed back. Therefore, an obstruction never occurred. Play on.
Hopefully the Cranbrook boys learnt something from all this.
1. A maul can take place only in the field of play.
2. It consists of a ball carrier and at least one player from each team, bound together and on their feet. A player ripping the ball from the ball carrier must stay in contact with that player until they have transferred the ball.
Given the ref blew his whistle prior to the grounding means the play has stopped. In this instance he could have agreed he got it wrong and maybe awarded a scrum to barker.
The ref can confer with his Assistant Referees (yes thats what they are called now) however is still 'The referee is the sole judge of fact and of law during a match. The referee must apply the laws of the game fairly in every match'
