Spouse visa application - driving ticket query

Hi, we’re filling my husband’s spouse application and I wonder about how to answer a question on driving offences. He was issued with a ticket at one of the London councils as he entered a zone that was apparently no entry for cars unless you’re a resident. We did our research online at the time as that restriction was put in a couple days before, and many people who were fined appealed, we appealed also and the appeal was successful, this was dropped by the council, he never had to pay the fine. Is this something he would need to disclose on the spouse visa application? My gut feeling says no but he is not certain. Thank you!
