The jack is right against the boundary. The last bowl of the end comes to rest on its own rink very close to the jack. Before the thirds start to measure the bowl falls and pushes the jack over the boundary line. One third wishes to replace the bowl and jack whilst the other calls the end dead. Which third is correct?
A jack is dead if it passes completely outside a side boundary of the rink of play. Law 19.1.2
A jack in the ditch is moved by a non-toucher played by team A entering the ditch. The team A third says “We have to agree on the replacement of the jack or the end is dead”. The team B third disagrees saying “It is my duty to re-position the jack”.
Who is correct?
The third of team B is correct. The third of the opposing team must restore the jack in the ditch displaced by a non-toucher entering the ditch to its former position. Laws 18.4 & 38.5.3
