Amending planning permissions and the implications of "Hillside"

In Hillside Park Ltd v. Snowdonia National Park Authority (‘Hillside’), the Supreme Court has revisited the principles for determining the validity of multiple planning permissions.

This important case considers the lawfulness of development pursuant to overlapping planning permissions and has potential wider implications for the planning strategy for development sites subject to multiple planning permissions and, in particular, the common practice of using ”drop-in” permissions.

This Note sets out some of the key principles of the Hillside judgment before considering the different routes available for amending planning applications and wider implications.
