The Judgment, by Honorable Mr Justice Collins will see the government go before the High Court by the end of the year.
Better Accessible Responsible Development (BARD) made the application, as they believe that the public have not been sufficiently consulted on the plans.
Stephen Turnbull, planning lawyer at law firm LG, comments: "Now that the High Court has granted permission for a judicial review, the deliverability of the Government's flagship policy is in doubt.
"The Government is shortly due to issue its much heralded Planning Policy Statement which is intended to, amongst other things, articulate its own policy, which local authorities then have to adhere to.
"It is difficult to see how this can be done with credibility whilst the judicial review process (which might take up to a year) goes on. If ultimately the eco towns policy is found to be unlawful by the Courts, it will be back to square one."
The Department for Communities and Local Government has said it would continue with the programme despite the impending review.
