Rule 31 - Four-Ball Stroke Play
All defined terms are in italics and are listed alphabetically in the Definitions section - see pages 2235.
The Rules of Golf, so far as they are not at variance with the following specific Rules, apply to four-ball stroke play.
31-2. Representation of Side
A side may be represented by either partner for all or any part of a stipulated round; both partners need not be present. An absent competitor may join his partner between holes, but not during play of a hole.
The marker is required to record for each hole only the gross score of whichever partner's score is to count. The gross scores to count must be individually identifiable; otherwise, the side is disqualified. Only one of the partners need be responsible for complying with Rule 6-6b.
(Wrong score - see Rule 31-7a)
31-4. Order of Play
Balls belonging to the same side may be played in the order the side considers best.
31-5. Wrong Ball
If a competitor is in breach of Rule 15-3b for making a stroke at a wrong ball, he incurs a penalty of two strokes and must correct his mistake by playing the correct ball or by proceeding under the Rules. His partner incurs no penalty, even if the wrong ball belongs to him.
If the wrong ball belongs to another competitor, its owner must place a ball on the spot from which the wrong ball was first played.
(Placing and Replacing - see Rule 20-3)

if, at the same hole, each partner is in breach of a Rule the penalty for which is disqualification from the competition or for a hole.
c. For the Hole Only
In all other cases where a breach of a Rule would result in disqualification, the competitor is disqualified only for the hole at which the breach occurred.
31-8. Effect of Other Penalties
