High Court, in planning and development judicial review proceedings, quashes decision of planning board to grant planning permission, on appeal, for the development of a solar farm, on the grounds that: (1) the board's failure to include the fact of planning appeal then before it in its 'Weekly List' was a breach of planning regulations which could not be regarded as insubstantial given that it directly adversely impacted upon the right of public participation in the planning process as provided for in primary legislation; and (2) the board was not entitled to take into account certain 'CEMP' measures in carrying out a screening exercise for appropriate assessment in all of the circumstances of the case.
