20. FOULS BY TOUCHING BALLS. It is a foul to strike, touch or in any way make contact with the cue ball in play or any object balls in play with anything (the body, clothing, chalk, mechanical bridge, cue shaft, etc.) EXCEPT the cue tip (while attached to the cue shaft), which may contact the cue ball in the execution of a legal shot. Whenever a referee is presiding over a match, any object ball moved during a standard foul must be returned as closely as possible to its original position as judged by the referee, and the incoming player does not have the option of restoration.
21. FOUL BY PLACEMENT. Touching any object ball with the cue ball while it is in hand is a foul.
22. FOULS BY DOUBLE HITS. If the cue ball is touching the required object ball prior to the shot, the player may shoot towards it, providing that any normal stroke is employed. If the cue stick strikes the cue ball more than once on a shot, or if the cue stick is in contact with the cue ball when or after the cue ball contacts an object ball, the shot is foul. If a third ball is close by, care should be taken not to foul that ball under the first part of this rule.
23. PUSH SHOT FOULS. It is a foul if the cue ball is pushed by the cue tip, with contact being maintained for more than the momentary time commensurate with a stroked shot. (Such shots are usually referred to as push shots.)
24. PLAYER RESPONSIBILITY FOULS. The player is responsible for chalk, bridges, files and any other items or equipment he brings to, uses at, or causes to approximate the table. If he drops a piece of chalk, or knocks off a mechanical bridge head, as examples, he is guilty of a foul should such an object make contact with any ball in play (or the cue ball only if no referee is presiding over the match).
25. ILLEGAL JUMPING OF BALL. It is a foul if a player strikes the cue ball below center ("digs under" it) and intentionally causes it to rise off the bed of the table in an effort to clear an obstructing ball. such jumping action may occasionally occur accidentally, and such "jumps" are not to be considered fouls on their face; they may still be ruled foul strokes, if for example, the ferrule or cue shaft makes contact with the cue ball in the course of the shot.
26. JUMP SHOTS. Unless otherwise stated in rules for a specific game it is legal to cause the cue ball to rise off the bed of the table by elevating the cue stick on the shot, and forcing the cue ball to rebound from the bed of the table. Any miscue when executing a jump shot is a foul.
27. BALLS JUMPED OFF TABLE. Balls coming to rest other than on the bed of the table after a stroke (on the cushion top, rail surface, floor, etc.) are considered jumped balls. Balls may bounce on the cushion tops and rails of the table in play without being jumped balls if they return to the bed of the table under their own power and without touching anything not a part of the table. The table shall consist of the permanent part of the table proper. (Balls that strike or touch anything not a part of the table, such as the light fixture, chalk on the rails and cushion tops, etc., shall be considered jumped balls even though they might return to the bed of the table after contacting items which are not parts of the table proper). In all pocket billiard games when a stroke results in the cue ball or any object ball being a jumped ball off the table, the stroke is a foul. All jumped object balls are spotted (except in Nine Ball) when all balls have stopped moving. See specific game rules for putting the cue ball in play after a jumped cue ball foul.
28. SPECIAL INTENTIONAL FOUL PENALTY. The cue ball in play shall not be intentionally struck with anything other than a cue's attached tip (such as the ferrule, shaft, etc.). While such contact is automatically a foul under the provisions of Rule 19., if the referee deems the contact to be intentional, he shall warn the player once during a match that a second violation during that match will result in the loss of the match by forfeiture. If a second violation does occur, the match must be forfeited.
29. ONE FOUL LIMIT. Unless specific game rules dictate otherwise, only one foul is assessed on a player in each inning; if different penalties can apply, the most severe penalty is the factor determining which foul is assessed.
30. BALLS MOVING SPONTANEOUSLY. If a ball shifts, settles, turns or otherwise moves "by itself," the ball shall remain in the position it assumed and play continues. A hanging ball that falls into a pocket "by itself" after being motionless for 5 seconds or longer shall be replaced as closely as possible to its position prior to falling, and play shall continue. If an object ball drops into a pocket "by itself" as a player shoots at it, so that the cue ball passes over the spot the ball had been on, unable to hit it, the cue ball and object ball are to be replaced to their positions prior to the stroke, and the player may shoot again. Any other object balls disturbed on the stroke are also to be replaced to their original positions before the shooter replays.
31. SPOTTING BALLS. When specific game rules call for spotting balls, they shall be replaced on the table on the long string after the stroke is complete. A single ball is placed on the foot spot; if more than one ball is to be spotted, they are placed on the long string in ascending numerical order, beginning on the foot spot and advancing toward the foot rail. When balls on or near the foot spot or long string interfere with the spotting of balls, the balls to be spotted are placed on the long string as close as possible to the foot spot without moving the interfering balls. Spotted balls are to be placed as close as possible or frozen (at the referee's discretion) to such interfering balls, except when the cue ball is interfering; balls to be spotted against the cue ball are placed as close as possible without being frozen. If there is insufficient room on the long string between the foot spot and the foot rail cushion for balls that must be spotted, such balls are then placed on the extension of the long string "in front" of the foot spot (between the foot spot and the center spot), as near as possible to the foot spot and in the same numerical order as if they were spotted "behind" the foot spot (lowest numbered ball closest to the foot spot).
32. JAWED BALLS. If two or more balls are locked between the jaws or sides of the pocket, with one or more suspended in air, the referee shall inspect the balls in position and follow this procedure: he shall visually (or physically if he desires) project each ball directly downward from its locked position; any ball that in his judgment would fall in the pocket if so moved directly downward is a pocketed ball, while any ball that would come to rest on the bed of the table is not pocketed. The balls are then placed according to the referee's assessment, and play continues according to specific game rules as if no locking or jawing of balls had occurred.
33. ADDITIONAL POCKETED BALLS. If extra balls are pocketed on a legal scoring stroke, they are counted in accord with the scoring rules for the particular game.
