“Need Help!! Improper Right Hand Turn, Sec. 144(9)”

So heres what happened. I was going down davenport and it turn into chruch st and had to make a left on bloor. I went southbound on church, managed to turn around and go northbound on church and got into the right lane as there were 2 cars in front making a right. i followed the vehicles and did not see a sign that there were no right hand turns. the officer was stopped at the corner just giving out tickets. the fine is $110 and is section 144 (9) of the highway traffic act. NOTE: the sign that was posted as to no right hand turns has been removed. Is there anything i can do? or possibly get off on some kind of technicality of some sort?
