Abstract
The paper is one of a long series of commentaries by the author, on application of regulations for solar access to multi-residential development. In this paper, the discussion relates to 'Planning Principles' formulated by the Land and Environment Court of NSW, Australia, to guide consistency in determinations of development applications. The author argues that the Principles are tested for robustness primarilly by experts appearing before the Court, and where this occurs with appropriate rigour, the Court responds by finding an opportunity to revise Principles.
