Town and country planning – Permission for development. In making judgements on the issues of housing requirements and housing supply, a decision-maker was not required to fix a figure for the precise extent of the authority's housing shortfall. The key question was whether the housing supply was above or below five years. The Planning Court, in dismissing the claimant's challenge to the refusal of planning permission, further held that a subsequent grant of planning permission could not have been a material consideration to which the principle of consistency could apply.
