Team A ties the score 53-53 after a made free throw by team A with only 10 seconds to go in the 4th qtr. With all the excitement involved, a team A player (A1) erroneoulsy grabs the ball to attempt a throw in under his own goal, the officials don't realize what is happening, A1 attempts an inbounds to A2 when B1 commits a foul against A2 while attempting a steal. What do you do?

You blow your whistle and say that you are calling team A for a delay of game warning for interfering with team B's ability to inbound the ball promptly. You act very strong about that being your call and that you are making your call before the foul occurred.

This is really not the same as team A delaying by violating the boundary on a throw-in in the final few seconds to stop the clock. In that case, we are supposed to ignore the violation.

If anyone gives you any grief, stare at their pants(an oldie but a goodie), then puke on their shoes (another blast from the past).

Good Call!!!

And don't forget to put the time back on the clock......

While I agree with the desire to undo the damage done by A (i.e., running time off the clock), is there a legal justification for this? There wasn't a timing error.

Yes. It's in the casebook under "A specific unsportsmanlike act" or similar.

Yes, bob. That is Case 9.2.11 Comment with 5 seconds remaining, or less.

Mick, Bob's got ya on this one!
See 10.1.8
It spells out exactly what to do.

YU.P., yU.P.
I went down the wrong road <s>again</s> yet.

Read Case Book play 10.1.8--there is a procedure for confusion and one for intentional.

That's the play that Nevada Ref cited above-about 6 hours ago.:D
