As others said. I actually had a few traffic and parking infringements at the time I applied, all of them paid. I went to court with one of them, it was my choice to dispute in court. I had forgotten about it but when I submitted my app I realised I had one I'd been in court for. So I submitted form 1023. At my interview, no questions asked. I didn't notify them of my other traffic / parking tickets.
So you read correctly, the instructions say only the ones you went to court with. Remember it's a character question as they could check any time and corroborate your answers.
