The committee in charge of reviewing local government boundaries has said re-organisation should stay on track despite a legal challenge by three Suffolk councils.
Forest Heath DC, Suffolk Coastal DC and St Edmundsbury BC have launched legal proceedings against the Boundary Committee for England (BCE), claiming its proposals for the county ignore local views.
They are pushing for a judicial review, because a plan for three unitaries covering Ipswich, West Suffolk and East Suffolk has not been included.
The two options currently on the table are a single unitary or two councils, one covering Ipswich and Felixstowe, the other covering more rural areas.
“The priority for us is to be heard. This is not a tactic to delay or derail the process,” said a spokesman for all three.
The legal action is also supported by Waveney DC.
The BCE is due to make a final report to communities secretary Hazel Blears by July 15.
“Both government and BCE have been clear they want to get this process completed as quickly as possible so unless we’re ordered otherwise we intend to provide final advice by July 15,” said a spokesman.
