22-1. Ball Assisting Play
Except when a ball is in motion, if a player considers that a
ball might assist any other player, he may:
a. lift the ball if it is his ball; or
b. have any other ball lifted.
A ball lifted under this Rule must be replaced (see Rule 20-3).
The ball must not be cleaned unless it lies on the putting green
(see Rule 21).
In stroke play, a player required to lift his ball may play first
rather than lift the ball.
In stroke play, if the Committee determines that competitors
have agreed not to lift a ball that might assist any other player,
they are disqualified.

22-2. Ball Interfering with Play
Except when a ball is in motion, if a player considers that the
ball of another player might interfere with his play, he may
have it lifted.
A ball lifted under this Rule must be replaced (see Rule 20-3).
The ball must not be cleaned unless it lies on the putting green
(see Rule 21).
In stroke play, a player required to lift his ball may play first
rather than lift the ball.
Note: Except on the putting green, a player may not lift his ball
solely because he considers that it might interfere with the play
of another player. If a player lifts his ball without being asked
to do so, he incurs a penalty of one stroke for a breach of Rule
18-2a, but there is no additional penalty under Rule 22.
