1st scrimmage ever (Boys varsity) on Saturday and it all went great for the first seven quarters and 7 minutes and 53 seconds .
A1 inbounds under their basket and throws a quick pass to A2 who then hesitates and then throws back to A1 who puts it in the basket to take the lead with 7 seconds left in the in the final quarter .
I blow the whistle and whistle a violation for A1 not establishing himself in bounds as he only had one foot in when he caught the return pass .
Right after I blew the whistle and made the call I knew I was wrong because he had one foot in and NOTHING out .
Coach was pretty pissed but he was pissed because he thought the kid had both feet in (Which he didn't) not because he knew the rule and knew I absolutely kicked it .
Team A wound up winning the quarter when they stole the subsequent inbound and scored so it eneded the way it should have with no thanks to me .

In a situation like this would anyone ever overrule themselves when they know they were wrong ? I really thought about it and then decided against it but the more I thionk about it the more I think I should have .

Yes -- it's called an accidental whistle.

Get it right
 

Accidental/inadvertent whistle. Either way....get the call correct. In some of these cases you will have to explain to both coaches cause either way one team is going to get hurt more than the other. Just explain, "Sorry coaches, brain fart on my part, player was definitley in bounds, whistle should not have been blown." If team control exists, give it back, otherwise go to AP. In your case, depending on when you blew your whistle, it may just be a new throwin.

Get it right. :)

Even high-level NCAA officials aren't immune to the inadvertent whistle. Dee Kantner had one in the Tennessee-Texas game last Thursday when she anticipated that a player was about to go out of bounds when she actually stopped just short. She immediately corrected herself, said, "Inadvertent whistle, my fault, white ball." Thought she handled it well.

That was a pretty well-officiated game, with Kantner, Lisa Mattingly and Wesley Dean on the crew. Of course, officiating is hardly a factor in a 41-point game.

I'd never overrule myself.

Oh wait, yes I would.

:D

Use the inadvertent whistle -- WHICH I HAVE ONLY HAD ONE OF SO FAR THIS YEAR!

It's easy if you realized the problem before you signalled or "called" the violation. Even part way through that process, you can sort of cough roughly, and then indicate a brain fart/inadvertant whistle. Once you've called it, signalled and started going on with the game, it's pretty tough to call it back. Technically, I don't think you can. But in reality, people do. Just don't try it very often.

By the way, don't call it a Correctable Error. It's not, as defined by Rule 2-10. It can be a Fixable Mistake, which means you can "fix" it, even though you'll lose some credibility in the process. Once the ball is live on the subsequent throw-in, it's really too late, though.
