6 on the court

[Zoochy]

Following a Time Out Team A has the ball for a throw-in. They complete the throw-in and A1 is dribbling. Coach B realizes he has 6 on the court. B6 runs off the court. An official observes this but lets play to continue. Team A misses a shot an Team B rebounds the ball. As they are moving the ball up the court. Coach B requests and is granted a Time Out. The officials huddle during the TO. Can they still call a Technical foul for too many players on tge court?

No. It must be called while it is occurring.

Why would an official observe this and let play continue?
The only reason that I can surmise is that a scoring play was in progress by the team with the correct number of team members on the court, so the whistle was temporarily withheld. Of course, it should be blown as soon as the scoring play is over.

This foul is penalized if discovered while being violated. Therefore, when an official discovers that a team is violating this rule, a foul occurs at that moment. Therefore, by 6-7-7, the ball becomes dead at that moment unless a try or tap is in flight or continuous motion applies. Since the only person who knows when exactly the foul occurs is the official who calls the foul, an official could easily hold off on the whistle if it seems like the fouling team's opponent has an obvious advantage, but technically, an official should wave off the basket if he notices there are six players before continuous motion applies.

It seems that technical fouls are a bit different from normal fouls or violations in that the spirit and intent of the rules which demands that a team not unfairly gain an advantage from breaking the rules allows some additional leeway.
Here is the Case Play supporting an official delaying the whistle and the ball remaining live after the commission of an act that warrants a technical foul, even when a try is not taking place.

10.4.1 SITUATION F:

A1 is driving toward the basket for an apparent goal when the official, while trailing the play advancing in the direction in which the ball is being advanced, is cursed by the head coach or bench personnel of Team B. How should the official handle this situation?

RULING: The official shall withhold blowing the whistle until A1 has either made or missed the shot. The official shall then sound the whistle and assess the Team B head coach or bench personnel with a technical foul. If the official judges the act to be flagrant, the offender shall be ejected. If A's coach or bench personnel was the offender, the whistle shall be sounded immediately when the unsporting act occurs. (10-4-1a)

La Ricardo and Nevadaref your points are well taken but they don't seem to apply to my post. A1 is slowly advancing up the court when the extra player was noticed. Plus they allowed Team B to get the rebound and slowly advance the ball to mid court before calling TO.
Case play 10.1.6 is sort of similar. That play states the official notices the extra play but cannot sound the whistle before the game ends. In my post the official does not make any attempt until the time out.
