So working a 3-man game.

I am L. There is a drive from T and it looks like A1 has B1 one his left. A1 is met by B2 who fouls A1 hard. I have a whistle. T comes in and wants to give info. I ignore the info and call the foul on B2, basically I did not consider the input as I only had contact by B2 and it was pretty significant.

After the game, T comes in and says I have to take his information and should have called the foul on B1. He informs me that B1 had fouled A1 and that this contact forced the contact by B2. I had a good look and A1 was going to be fouled by B2 either way.

He says he had whistle on the play, but I did not hear it - must have been simultaneous.

My questions: Do I have to take his info and give a foul that I did not see to B1? Or is my partner wrong?
