David Reade QC, leading Dominic Bayne of Parklane Plowden Chambers, appeared in the Supreme Court on 7 November 2016 in Monk v Newbiggin, an appeal against the decision of the Court of Appeal,  1 WLR 4817. The case concerns the correct approach to the valuation of non-domestic property for rating purposes. The case before the Supreme Court raises fundamental questions about the meaning of and approach to repair and disrepair in the rating regime. The Court of Appeal judgment signaled a change of approach in ratings valuation that had significant consequences for the development of commercial property. Judgment has been reserved.
