Key Facts
- •Judicial review of planning permission granted for a solar farm development.
- •The development's capacity was a central issue, specifically whether it exceeded the 50MW statutory threshold for local planning authority approval.
- •Two applications were made: one for full planning permission and a subsequent non-material amendment (NMA).
- •The claimant argued the planning permission approved a solar farm exceeding the 50MW capacity threshold, requiring national, not local, approval.
- •The claimant also argued that the approved footprint of the solar farm was larger than necessary, a material consideration overlooked by the council.

Outcomes
Planning permission quashed.
The council failed to consider the material consideration of whether the approved solar farm's size was larger than necessary to achieve a lawful capacity (below 50MW).
Non-material amendment quashed.
The NMA was based on an incorrect interpretation of the planning permission and did not cure the initial unlawfulness.
