Cash-and-carry store Bestway last month threatened a challenge over plans for a waste handling and gasification plant that would mean the compulsory purchase of one of its sites (Planning, 15 October, p3).
The London Borough of Barnet has now granted full permission for the giant £4.5 billion scheme following the signing of the section 106 agreement.
"The council has been carrying on regardless and that it has approved the scheme is not surprising," said Bestway head of property Malcolm Carter. "However, we need to see the final wording of the agreement and the details of what has been approved before deciding how to proceed."
Coalition for a Sustainable Brent Cross Cricklewood Plan member David Howard added that more than one challenge is possible. "It is my understanding that there are several judicial reviews being discussed," he said. "Bestway knows that we are willing to give evidence."
Barnet granted outline permission last November and communities secretary Eric Pickles decided not to call in the plans in June.
Brent Cross Cricklewood Development Partners development director Jonathan Joseph said: "A vital part of our work moving forward will be engagement with the community to ensure that everyone is fully involved and informed."
