Hillside Parks Ltd v Snowdonia National Park Authority [2022] UKSC 30

Hillside incompatible planning permissions is the modern Supreme Court authority on overlapping permissions and when later development makes an earlier planning permission incapable of further implementation. The case is not really about abandoning a permission. The central question is physical compatibility: can the development authorised by the earlier permission still be carried out after what has subsequently been built?

Nathan Gardiner v Hertsmere Borough Council & Anor [2022] EWCA Civ 1162

Gardiner retrospective CIL is a leading Court of Appeal authority on self-build relief where development began before planning permission and was later regularised retrospectively. The court held that the CIL self-build exemption could not be secured after the event. With a retrospective section 73A permission, the permission and deemed commencement arise together, leaving no pre-commencement window in which the statutory exemption steps can be completed.
