Planning Policy Assessment Framework
Planning authorities must assess development proposals against all planning policies and material considerations, reading this statement alongside development plans, the Regional Development Strategy, and supplementary planning guidance.
In exercise of its responsibility for development management in Northern Ireland, the planning authority will assess development proposals against all planning policies and other material considerations.
The planning policy in this statement must therefore be read together with the relevant contents of development plans and other planning policy publications, including the Regional Development Strategy. The planning authority will also have regard to the contents of published supplementary planning guidance documents.
