In DARWALL v DARTMOOR NATIONAL PARK AUTHORITY (2025) UKSC 20 the appeal to the Supreme Court, on whether there was a public right to camp, turned on a short print of statutory construction (regarding the meaning of Section 10(1) of the Dartmoor Commons Act 1985). The Supreme Court stated, at paragraph 15: “Normal principles of statutory interpretation are engaged. The courts in conducting statutory interpretation are seeking to ascertain the meaning of the words used in the light of their context and the purpose of the statutory provision.” From para 17 to para 38 the Court considered the ordinary meaning of Section 10(1) and its legislative context in the 1985 Act and earlier.
The Supreme Court then addressed other aids to interpretation of Section 10, (1) Hansard material (paras 39-43), (2) the principle of legality where there is no ambiguity (paras 44-47), (3) Committee Reports (paras 48-51), and (4) Devon County Council byelaws (paras 52-53).
On the nature of the relief sought and the procedure used, the Supreme Court observed that it was a “striking feature” of the proceedings that the public was not represented. Consideration should have been given to the joinder of the Attorney General.
