A request for a judicial review, made by one of the travellers at the illegal camp site in Shurlock Road, has been refused by the High Court
Mrs Jane Eastwood had applied for a review of the council's decision to refuse planning permission to change the use of the site in Waltham St Lawrence into a permanent traveller camp in December.
But the request was turned down because the Secretary of State had already decided not to overrule the council's decision.
Cllr MJ Saunders, cabinet member for planning and property, said: "We are delighted to receive this news which vindicates yet again the council's decision to decline to determine this application.
"However, there is still a very long way to go before this site can be restored to its intended and original greenbelt condition."
The borough has also been hit with a second application for a judicial review of which it is still waiting for a response.
This relates to its decision to take direct action to clear the camp in April.
The 40-plus occupants of the of the site have lived there since 2009.
