While we are waiting for the non-Francophones/nonTechnophones to sort themselves out I have a few comments.
I have taken an interest in campaigns against overnight restrictions on Motorcaravan Parking, including one by Andy Strangeways against various councils on the NE Coasts of England
He already had a successful campaign in Scotland to have all the signs on the national roads removed, which is why one can MH and wild camp in Scotland almost anywhere.
I came across his campaign by accident. He does not have a MH, but has come across restrictions and up against the councils in various places in the past for sleeping in his car. As a result he could see joint cause with MHomers.
He does not just campaign on the basis that the law should be changed. He challenges the legality of the restrictions that are currently in place, and has had some success and some signs have been removed.
Furthermore he has found councils who appear to have :-
1 Not followed correct procedures - either to ride roughshod or through incompetence.
2 Taken evidence into account only when it suited them to restrict parking.
3 Councils not following legal procedures to submit bye-laws for approval by central government,
4 Councils erecting signage not in accordance with central government legislation
5 Councillors or their Officers lieing in written resopnses or making Defamatory statements
6 Councillors not declaring interests, some of which were in campsites.
7 Councils refusing rightful public access to meetings
Some Councillors have resigned over a combination of these breaches.
I am not a total supporter of some of the smaller fights he picks, but I am not privy to the whole picture and, as a lawyer I know, that sometimes the other side is trying to undermine one's case with colateral damage and one has to fight that colateral issue, even if it seems irrelevant to an outsider.
These have and are continuing to be legal challenges to breaches of the law - not pleading for extra privileges.
My main point about posting the details of this campaign is that maybe there is a lesson to be learned in our attempts to gain better access for places to park.
Instead of pleading/writng letters/moaning in the press etc. maybe we should do more research about whether we are being illegally restricted in the first place.
The case that John cites in his OP is another example of some local interests and officials trying to overide freedoms of the public.
John, thanks for bringing up the whole topic.
If anyone is interested in Andy Strngeway's campaign this is the link
Andy does the work as a volunteer but is supported by donations from motorhomers.
