30. BALLS WRONGLY
REMOVED OR NOT REMOVED FROM GAME
GENERAL
If it is discovered before the end of the game that play has been affected
because either:
a ball
has been removed from the game under the misapprehension that it has been
pegged out; or
a ball
has not been removed from the game in accordance with Law 15
when it has been pegged out
all play from and including the first
affected stroke is deemed not to have occurred, any points scored for any ball
therein are cancelled, the balls are replaced in their lawful positions at the
end of the stroke preceding the first affected stroke and, subject to Law 30(b),
the player entitled to play at that time continues his turn without penalty.
If it cannot be determined when play was first affected it is deemed to be when
the ball was first misplaced.
EARLIER
ERRORS If it is also discovered that the limit of claims of one or more
errors had not passed when play was first affected, the relevant laws shall
be applied as if the error or errors had been discovered at that time.
