Official BCA One Pocket Rules Page 2

11.1 Keeping track of which pocket is whose It is each player's responsibility to keep track of which pocket is theirs; opponents are under no obligation - other than good sportsmanship -- to correct such an error prior to an opponent's shot. A ball legally pocketed in the wrong pocket counts for the player who legitimately has that pocket, regardless of who shot the ball. However, a ball shot into the wrong pocket does not entitle the shooter to continue their inning, unless on the same stroke they legitimately score into their own pocket as well.

11.2 In the event that a player shooting into the wrong pocket is permitted to continue the same inning at the table (beyond what is entitled by legally pocketing a ball in their own pocket) by their opponent's or the referee's failure to notify them of their error, such failure of notification does not legitimize any additional balls pocketed in that inning, whether pocketed in the shooter's pocket or their opponent's pocket. Thus the first shot to the wrong pocket in a given inning is the shooter's responsibility, and the shooter's opponent is entitled to any balls pocketed on that first stroke. However, any subsequently pocketed balls in the same inning are to be spotted as illegally pocketed balls, because it is the referee's or opponent's responsibility to notify the shooter before they erroneously continue their inning.

12. Close calls and conflict resolution

12.1 Unless a referee is assigned, players shall be responsible for refereeing their own match. Whenever the players themselves can come to an amicable agreement on any scoring or officiating issues to their satisfaction, and play continues, their decision shall be deemed final. If at anytime in a match either player anticipates a close call, or would like a neutral party to spot a ball, or wishes to have an official ruling in any conflict, then an official should be called. The non-shooting player bears extra responsibility to call an official if they anticipate a close call. In the event of any ?too close to call' situation, arbitration should favor the shooter unless there is verifiable mitigating evidence in the judgment of the official. In the event of a disagreement over a contested ball, with no evidence in the judgment of the official to warrant crediting the ball to either player, then the contested ball shall be deemed a neutral ball, and spotted according to rule 9.4.If there is no tournament official, then the ?house man' or another mutually agreed on impartial observer should be summoned to arbitrate. Their decision should be considered final.
