reverse call on over and back??

[MJT]

I worked with a guy 2nt and while riding to the game he asked me the following. "Last week I was the lead and a pass went to the backcourt and was slightly touched. The trail did not see the touch, it was barely noticable, so he called over and back. Should I have change the call."

I said I didn't think so, but would get input on the board with some more "experienced" officials. I think this is different than a ball going OOB's which you may talk to your partner, and end up changing the call.

Would you do it, and CAN we. I know it is not a listed "correctable error", but I don't think it falls into that "category" either.
