In a singles match the jack is rolled and appeared likely to enter the front ditch had it not hit the foot of the marker. The opponent claims the right to roll the jack.
Is the opponent correct?
No. The jack has been displaced by a neutral person. It must be re-delivered by the player who originally delivered it. Definition C.23.1; Laws 38.3.1; 9.4
The lead in team A delivers the jack which passes the 2 metre mark. Before it comes to rest Skip A picks it up assuming that it will not reach the ditch and places it on the 2 metre mark. Skip B objects. What should happen now?
The jack has been displaced by a player of its own team therefore it must be re-delivered by the opposing lead who may reset the mat but must not play first. Law 18.104.22.168
