This really stinks. I feel for you. As far as contesting the ticket, however, I don't think you have any ground to stand on, legally speaking. At it's root, it IS the other guys fault (because he ran a red and passed you on the ramp). So it WAS illegal for him to get to the postition he was in. However, technically speaking, once he was in that position, you DID fail to yield. Hence, technically, you're guilty of failure to yield.

I'm not saying it's right (moraly), and I'm not a lawyer, but I think that's what they'd say if you took it to court.
