Developer Larkfleet Homes has welcomed the decision by a court which allows it to mount a legal challenge to the building of the new Grantham bypass.
Lord Justice Sullivan has given Larkfleet permission to take its case to the Court of Appeal.
A Larkfleet spokesman said: “Larkfleet Homes is pleased that Lord Justice Sullivan has given us leave to appeal to the Court of Appeal on the issue of the planning permission for the Grantham Southern Quadrant Relief Link Road (SQLR) and recognises that we have a realistic prospect of success.
“Larkfleet Homes is very supportive of the growth of Grantham and to the principle of the southern quadrant development proposal.”
It had been hoped that building work on the bypass would start as early as March this year.
The spokesman added: “The issue surrounds the southern quadrant housing development and the SQLR which cannot proceed without each other and will have significant environmental impacts when taken in combination. They represent one project for environmental impact assessment (EIA) purposes.
“Our concern is that the EIA for the road has looked at the impacts of that proposal in isolation without taking into account the environmental impacts of the housing project.
“This is key because the EIA for the housing development may identify significant environmental effects that need to be addressed but it will be too late to do anything about them because the planning permission for the road will already be in place and, indeed, the construction of the road will have begun.
“We believe, therefore, that the permission for the road is not lawful and should be quashed.
“The construction of the road is likely to be delayed while these legal issues are resolved but it is important to be clear that this isn’t about obscure legal technicalities. It is about getting major growth right for the current and future residents of the town and their ability to effectively engage as key stakeholders with full knowledge and transparency of the details, impacts and mitigation measures proposed for this major development project for the town.”
