What happens if the skips cannot agree on the jack's position after it has been moved?

When skips cannot agree on the jack's position after it has been moved, the appropriate course of action is to declare the end dead. This rule is in place to ensure fairness in the game, as the disagreement can create confusion over the legitimate playing conditions. Since both teams have a vested interest in the positioning of the jack, if there is no consensus, it is not possible to continue the end fairly. Therefore, the end is effectively canceled, and no points will be awarded to either team for that particular end. Teams can then proceed to the next end with clarity on the rules.

The other choices would not appropriately resolve the situation; stopping the game or involving a tournament supervisor does not address the need for clarity between the teams. Replaying the end is also not feasible since the disagreement itself has caused the end to become contentious.
