See Law 17.6 (g) which deals with your specific scenario
Or, in other words .... a collapsed maul that becomes unplayable = turnover.
Agree... but is the ruck that results (in this case - I know its fairly rare) a totally seperate event?
Clarification in Law by the Designated Members of the Rugby Committee
There is a further variable to be taken into account when the ball goes to ground at a collapsed maul and there are players from both sides on their feet bound over the ball so that Law 16 – Ruck becomes applicable.
So do ruck laws now take precedence over the previously applicable maul laws? If so, then 16.7 (a) is what I went with. I'm happy enough with either - just wondering which takes precedence. I note that there is disagreement on these boards! :deadhorse:
