Skip A trails the jack into the ditch.
Skip B delivers his bowl and as it’s coming to rest, no one can tell if it will stop on the rink or fall into the ditch. It hangs on the edge and starts to fall over into the ditch and onto Skip A’s toucher bowl there.
Lead A, who is a six-month novice, catches Skip B’s bowl as it rolls over the plinth but before it comes in contact with Skip A’s toucher. Then he places it on the bank.
Skip B protests that Lead A displaced a bowl in course because the bowl could have rested on the toucher and not fallen into the ditch.
What is your ruling?
And secondly, does your ruling change if Skip A has delivered his next bowl before the protest is made by Skip B?
