Situation this past weekend - Do over

[grizwald]

Team A down 2 points side out at about the free throw line, across from the table. Time on clock is 1.4 seconds

A1 throws an errant inbounds pass that is heading for the table. B1 should have let it go, but instead tries to corral the pass in on the sideline. She puts her left hand on the table to keep her balance while she grabs the ball with her right hand.

The timekeeper does not start the clock because he's thinking that she is OOB. In retrospect he said he should've started the clock, because there is no whistle from the refs. I guess they didn't see the hand on the table since this was a distance from where they were set up to watch the last play.

The problem is, as B1 is steadying herself for what had to be at least a second. A2 steals the ball at half court, throws a pass to A3 who shoots a bank shot from about 25 feet, it goes in. The timekeeper starts the clock when A2 steals the ball. The buzzer sounds as the shot is in flight.

After much debate, the refs initially signal the basket good Team A wins by 1. However, after another discussion with the coaches and timekeeper, they decide to put 1.4 back on the clock and play it again.

From following discussions on this board, I don't think I've ever heard of a do-over per the rulebook on here. If I follow the discussions on here closely enough, I'd have to think either the basket counts or it doesn't count based on whether the refs had definite knowledge of the correct time on the clock. Correct?

I know at higher levels they have TV monitors to look at for something like this. However at youth levels, what is correct ruling? If I'm correct about the definite knowledge part, what would constitute definite knowledge? Just common sense knowing that she had to have held the ball for a second combined with the timekeeper acknowledging that he didn't start the clock during that time. Would that be good enough? Any thoughts?

High School rules, if it matters.
