Final answer:
To prevent protests at RAF Fylingdales, the RAF and local authorities would need to use delegated legislation that is viewpoint-neutral, with possible measures including requiring permits or establishing free-speech zones in a balanced manner that respects civil liberties.
Step-by-step explanation:
The RAF and the North York Moors National Park seeking to control or prevent protests at RAF Fylingdales would need to use delegated legislation, which involves rules or regulations granted by an Act of Parliament. Depending on the specific circumstances and legal framework in place, this could take the form of a by-law, or specific provisions under public order legislation. The regulations imposed must be viewpoint-neutral and cannot discriminate against a group based on their beliefs or opinions.
To ensure public safety and order, the authorities could require protest organizers to secure a permit in advance or give sufficient notice so that security measures can be arranged. In past controversial instances, free-speech zones have been established to limit the area where protesters can gather during significant events, although this is sometimes seen as a way to minimize the impact of the protest.
Ultimately, any action taken by the RAF or other authorities will have to strike a balance between the right to peaceful assembly and protest, and the need to maintain public order and safety, while also ensuring that the regulation does not infringe on civil liberties.
