Travellers at the UK's largest illegal travellers site, at Dale Farm, Essex, have won a court injunction delaying their planned eviction.
Residents won the injunction restraining Basildon Council from clearing the site pending a further High Court hearing on Friday.
Earlier bailiffs urged campaigners to stop obstructing the eviction process as they prepared to access the area.
As many as 400 people have been living on 51 unauthorised caravan plots.
Mr Justice Edwards-Stuart granted the injunction at London's High Court on the basis that there was a realistic apprehension that the measures to be taken - while genuinely believed in by the council - "may go further" than the terms of the enforcement notices.
He said: "Having regard to the fact there is no fixed date for starting these - but they are imminent - I do not see that any serious injustice will be caused if the actual implementation of any measures will not take place before the end of this week."
There were cheers inside the Dale Farm site as residents and supporters were told the news.
Resident Mary Slattery said: "We are delighted. Every day is a bonus. We've got one last chance and we're not going to give up - this gives us so much hope."
There was a party-like atmosphere as music began to play and travellers taunted bailiffs from the barricades, singing: "We're not going to go."
When they heard about the injunction, supporters who had chained themselves to the barriers began to unlock themselves.
Supporter Jake Fulton said: "This is really great news but this isn't over yet.
"It makes us feel we have a really good shot at defending travellers in a way that has never happened before."
