Officials at South Northamptonshire Council have announced they will take part in a High Court legal battle against the controversial HS2 high speed rail line.
The authority will join 14 other councils in the fight against the line, which would pass through parts of south Northamptonshire.
The case will be heard at the High Court next week and is expected to last about two days.
Councillor Rupert Fordham, the council’s cabinet member for economic development and regeneration said: “Those residents and businesses in South Northamptonshire that will be affected by the planned route have put their faith in this authority to help them in their fight against it.
“The environmental and economic impacts have not been properly considered.
“The project is expensive, wasteful and environmentally destructive. It would therefore be remiss for us to sit back and allow a project that will have a detrimental impact on the quality of so many people’s lives to go unchallenged.
“We recognise the need for investment in the country’s rail network but spending £34bn on HS2 is not the way to do it.”
