In 2002 a plan to regenerate Hastings and Bexhill was approved. The proposals were for a mixed development that would proceed in two phases. Phase 1 included the submission of a detailed planning application for infrastructure proposals, and associated surface water attenuation measures, for part of the site. Phase 2 would be the subsequent submission of an outline planning application for the wider project.

In 2004 the interested party submitted a planning application with regard to phase 1. A detailed ecology report relating to the application site was also produced. That report acknowledged that there would be a separate application with regard to phase 2 and that there would be an environmental impact assessment with regard to phase 2, which would also include phase 1. Planning permission was granted by the council on 15 October, subject to conditions.

The claimant applied for judicial review of the council’s decision to grant planning permission.

The essential issue concerned the interpretation of the Town and Country Planning (Environmental Impact Assessment) (England and Wales) Regulations 1999. In particular, whether in circumstances where an application for planning permission is for a development which, taken on its own by reference to the application, would not require an assessment of the likelihood of significant effects on the environment, such an assessment is required if at the time that development is prospectively part of a wider development.
