Last year, the Friends of Grandpont Nature Park sought a judicial review challenging the legality of the Council’s decision to grant planning permission for the Oxpens River Bridge.
The High Court has now ruled on the case, dismissing all five challenges.
Councillor Susan Brown, Leader of Oxford City Council, said: “We welcome this outcome, which upholds our planning decision in full.
“While it is important that people have the right to challenge decisions through the legal process, the Government has been clear judicial reviews should not be used to block much-needed infrastructure that benefits communities.
“With the decision made, we can now focus Council time and public money to progress delivery of the bridge. Once complete, it will provide an essential, safe, and attractive walking and cycling route linking new homes and jobs at Oxpens and Osney Mead with the city centre.”
