In Halcrow v. Crown Prosecution Service, (EWHC, March 10, 2021), the England and Wales High Court held that the religious freedom rights of pagan and Druid protesters at Stonehenge were not infringed when they were convicted of violating restrictions on entry to the stone circle in violation of provisions of the Ancient Monuments and Archaeological Areas Act 1979 and the Stonehenge Regulations. The court said in part:
[T]he removal of restrictions on access to the stone circle because the appellants turned up and wanted access to the stone circle to protest and exercise religious freedoms, would not strike a fair balance between the important rights of the individual appellants and the general interest of the community to see Stonehenge preserved for present and future generations. This is because it would have meant in practice that access to the stone circle would have had to be lifted as and when any person chose to walk into the stone circle, so long as they were protesting or exercising religious rights. Such access would inevitably have an adverse effect on Stonehenge to the detriment of current and future generations. Therefore the interference on the specific occasions with the appellants' rights under articles 9, 10 and 11 of the ECHR [European Convention on Human Rights] was justifiable and proportionate.
