The session will review the existing case law, discuss the judgment and look at what it means for schemes where one or more planning permissions have ‘slotted in’ to part of an existing permission.

The discussion will include practical tips for developers and LPAs on how to structure overlapping planning permissions to ensure an acceptable and workable position for both parties, and how future developments in the law could be amended to provide greater clarity to this important area of planning and development.
