Campaigners say they plan to hold a peaceful rally outside Dartmoor National Park headquarters during Friday’s authority meeting.

Dartmoor Wild Camping Action Group said it believes the authority will be discussing an appeal against the court ruling in the case brought by landowner Alexander Darwall.

The hedge-fund manager, who has owned the Blachford Estate and Stall Moor, north of Ivybridge, since 2013, argued that the Dartmoor Commons Act 1985 did not give the public the right to camp without the landowner’s permission.

Sir Julian Flaux, Chancellor of the High Court, ruled in his favour, effectively ending the long established practice of wild camping without the owner’s permission that the act was understood to grant.

Since then, the national park authority has agreed to pay landowners for a permissive arrangement that allows outdoor enthusiasts to continue camping in certain areas.

Campaigners said they will meet at 8am at the headquarters at Parke, Bovey Tracey, near Newton Abbot.

A spokesperson said: “We plan to pitch tents on the grass with messages of our support of an appeal on. Signs, banners and drums will be appreciated.”

Organisers urged people to use public transport to travel to the rally if possible.
