The High Court dismissed an environmental group's challenge against a planning permission granted based on an extended Local Area Plan (LAP), which the group claimed was invalid due to lack of a Strategic Environmental Assessment (SEA) at the time of extension. The court found that the challenge was an impermissible collateral attack on the unchallenged decision to extend the LAP. The court also noted that the group failed to activate any remedial obligation or demonstrate any effects of the alleged non-compliance with the SEA Directive. Consequently, the legislation was not invalid, and the LAP remained in force, rendering the group's claim unsustainable.
