Residents opposed to a new windfarm near Thorney, Cambs, say they will take their objections to the European Court of Human Rights.
Seven 100-metre turbines are to be built at Wryde Croft
Campaigners were angered by a decision not to debate the issue at a full council meeting this week.
Campaign group Fenland Against Rural Turbines has said the farm will cause noise pollution and spoil the area.
It claims the seven 100-metre turbines at Wryde Croft would be built too close to houses.
The council voted 6-2 in September to approve the turbines, to be built by the company Renewable Energy Systems.
On Tuesday, two councillors who had earlier asked for a full council debate on the issue withdrew their request.
Graham Murphy, the chairman of Peterborough's planning and environmental protection committee, said the council had explored all avenues before deciding not to discuss it further.
