5-8-4: Time-out occurs and the clock, if running, shall be stopped when an
official: Responds to the scorer’s signal to grant a coach’s request that a
correctable error, as in 2-10, or a timing, scoring or alternating-possession
mistake be prevented or rectified. The appeal to the official shall be
presented at the scorer’s table where a coach of each team may be present.

5-11-4: Only one 60-second time-out is charged (or one 30-second
time-out, if that is the only type of time-out remaining) in 5-8-4 regardless
of the amount of time consumed when no correction is made.
EXCEPTION: No time-out is charged: If, in 5-8-4, the error or mistake is prevented or rectified.

5.8.4 SITUATION A: The appeal of the coach of Team A to an official, made while the ball is dead and the clock is stopped, is made when it is too late for correction of an error. RULING: Following the conference, the 60-second time-out remains charged to Team A and they are given the privilege of utilizing whatever time remains. The official will terminate the discussion with the coach immediately upon making a decision. If the discussion takes more than one minute, only one 60-second time-out is charged. (2-10-2; 5-11-4)

5.8.4 SITUATION B: The head coach from Team A requests a 60-second time-out to rectify a timing error. The referee grants the time-out to investigate the matter, but determines that no correction can be made. The scorer then informs the referee that Team A cannot be charged a 60-second time-out as they only have one 30-second time-out remaining. RULING: Since they have no 60-second time-outs remaining and there was no timing correction made, Team A will be charged their remaining 30-second time-out regardless of the amount of time consumed. (5-11-4)

2-10: Officials may correct an error if a rule is inadvertently set
aside and results in:
a. Failure to award a merited free throw.
b. Awarding an unmerited free throw.
c. Permitting a wrong player to attempt a free throw.
d. Attempting a free throw at the wrong basket.
e. Erroneously counting or canceling a score.
ART. 2 In order to correct any of the officials’ errors listed in Article
1, such error must be recognized by an official no later than during the first
dead ball after the clock has properly started.
ART. 3 If in Article 1e the error is made while the clock is running and
the ball dead, it must be recognized by an official before the second live
ball.
