The Court of Appeal agreed to review a High Court decision to allow the transfer of thousands of homes from Tower Hamlets Council to a housing association to proceed.
The decision, which halts the transfer, was claimed a victory by Carole Swords, who is the Tower Hamlets tenant spearheading the legal bid to secure a re-ballot for the Parkside estates.
Ms Swords has fought a legal battle to prevent the transfer of the 2,200 homes on the estate to Old Ford Housing Association. Tenants narrowly voted in favour of the transfer in July 2005, but Ms Swords claims there were 'irregularities' in the way the ballot was conducted.
Court of Appeal judge Lord Justice Toulson granted permission to appeal, ruling that the application for Judicial Review raised arguable issues. The Court Order states: "The grounds of the appeal and the skeleton argument also raise arguable points and the subject matter is important. It is important to resolve the issues with the utmost speed."
The Government appeared to be moving towards an overhaul of the way council tenants can take over the running of their homes.
Current procedures require residents wanting to set up a tenant management organisation (TMO) to prove that the majority of people on their estate are in favour of the move, even if there is no opposition.
Plans being prepared by a government-led review group would see TMOs formed if supported by a ballot similar to those for stock transfers.
The review group was set up to examine tenants' right to manage after the publication of the local government white paper last year, which indicated a need for more TMOs. The review group is in the final stages of preparing its proposals.
