vapros and Doc, this is the complete rule.
Steve, came up with 6.6.2 Serious Foul to act judgement when a previous rule develops into a serious foul. When no referee is involved then 6.1 with 3 balls disturbed and can be restored then it is suggested a. standard foul with an opponent's option to restore, and if the 3 balls have an effect upon the shot, then it reverts to player's decision a., b., or c. 6.6.1 it is penalty a., b., or c. that is decided upon by the players.
6.1 Cue ball fouls only: When a referee is not presiding over the match, One Pocket may be played whereby disturbing a single object ball is not a foul, as long as there is no effect on the shot. For clarification, it is always a foul to disturb the cue ball, and it is also a foul if a disturbed ball has any effect on the shot; meaning if the disturbed ball has contact with any ball in motion, or if any ball passes through where the disturbed ball originated. It is always a foul when two or more balls are disturbed. When multiple (3 or more) balls are disturbed it is considered a serious foul. ref: 6.6.2 Serious fouls
6.1.1 Restoring a position: There is no restoration option when any disturbed ball has had an effect upon the shot; in that case the balls must be played from where they lie. Once it is acknowledged that a ball or more was disturbed with no effect on the shot, then the opponent must be given the option to restore the position or leave the balls as they lie before play is resumed. If the opponent elects restoration, it shall be as near as possible to the original positioning according to both players, with the opponent responsible for final approval. It is a foul upon the shooter to restore a ball without permission from the opponent. However, if the shooter was notified, yet resumes play without the opponent’s consent to the final disposition of a disturbed ball, then it is a breach of the restoration option, and a serious foul on the shooter. ref: 6.6.2 Serious fouls
6.6.2 Serious fouls: If the ruling is that a serious foul has occurred, in addition to the standard foul the official may further penalize a player at their discretion. If there is no official available, players will need to come to agreement themselves as to the level of penalty to assess the shooter. If it is possible to restore the balls, then the foul may be penalized (a) as a standard foul, with opponent’s option of restoration.
The following penalty levels progress from (a) through (c) depending on the seriousness of the offense, and whether the shooter has been issued a prior warning. A prior warning warrants an escalation of penalty. In this context a “prior warning” may mean a prior offense, a pre-tournament announcement or a player agreement prior to a match.
(a) Assess a standard foul penalty, and a warning to the shooter.
(b) Assess a standard foul penalty, and opponent receives the option of ball in hand.
(c) Loss of game.
