AI confidence in this short overview: high
This appeal concerned the market (best consideration) value on 5 April 2012 of 8.08 acres of development land in Pontyates sold off‑market to a related purchaser. The tribunal preferred comparable‑sales evidence over residual valuations because of uncertain inputs to the latter, inspected the sites and comparables, and fixed the value at £80,000 per gross acre, totalling £646,400 (rounded to £645,000). The appeal against HMRC's £800,000 valuation was allowed in part.
Ratio decidendi
This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.
AI confidence in this ratio decidendi summary: medium
Where residual valuations depend on numerous uncertain or untested inputs, a tribunal may place little weight on them and instead prefer well‑selected comparable‑sales evidence supported by site inspection; market value should reflect what could have been achieved if the property had been openly exposed to the market on the valuation date, with adjustments for relevant site characteristics and constraints.
Obiter dicta
This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.
AI confidence in this obiter dicta summary: medium
The judgment noted that unexercised developer option agreements indicate interest but have limited utility in proving market value where not exercised, and that broad quantum adjustments (for example between four and eight acres) are inappropriate without specific evidential support; physical features such as slope and site division materially affect comparability.
