Last Wednesday, 14 Feb, I filed the skeleton argument with the tribunal and sent a copy to Bexley. It was 3 pages of careful argument pointing out the frailties of their case.
Yesterday, 19 Feb, they sent me an email saying theycouldn't discuss the case with me as I am not the registered keeper (my authority letter is on file!)
Today, 20 February, the tribunal phoned me to say that Bexley have changed their mind about the Appeal and PCN and have now cancelled it.
Hurrah. I now only have 7 cases at the tribunal on Thursday.
