Moves are being made to challenge Tunbridge Wells Borough Council in the courts over their planned £90million Calverley Square.
The Times understands that legal papers have been filed by an individual associated with the Tunbridge Wells Alliance, the political party founded to oppose the development.
Planning permission has been granted for the development, which will see a theatre, offices and council chambers built on land next to Calverley Grounds.
Critics of the development have raised objections, including that the cost is too much and the large design could spoil the surrounding landscape.
A legal challenge is one of the few remaining chances opponents have to stop the process.
The individual is seeking a judicial review to challenge the legality of the development and processes behind it.
Alliance Chairman Bob Atwood previously told the Times: ‘We are looking at a number of ways to stop the development from being built.
‘Mounting a legal challenge is one possible action.’
Yesterday, Mr Atwood said he had nothing to add to these comments, but said ‘watch this space’ for developments.
Tunbridge Wells Borough Council was approached for a response, but nothing had been received at the time of going to press.
What is a judicial review?
This is areview is a court proceeding that reviews the lawfulness of a decision made by a public body.
It challenges the way a decision is made to check correct procedures have been followed, rather than the conclusion of a decision.
This could mean the public body will be able to make the decision again if it does so in a lawful way.
