AI confidence in this short overview: high
This appeal concerned the valuation methodology for the enfranchisement price of 8 Chester Street where an unusual head-lease escalator entitled the freeholder to rising shares of premiums/income from 2026. The Tribunal held that separate "core" statutory valuations must be made for the freehold and the head leasehold excluding marriage/hope value, that transaction routes which depend on coalescence with the enfranchising tenant must be treated as marriage/hope value, and that certain non-coalescing avoidance routes may be included in core value but with risk discounts and adjusted capitalisation/deferment rates. The appeal was allowed and the enfranchisement price fixed at £1,292,245 (apportioned £1,290,291 to the head leaseholder and £1,954 to the freeholder).
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: high
The binding ratio is that under s.9(1A) and Schedule 1 the statutory valuation process requires separate core valuations of superior interests excluding marriage/hope value, with marriage/hope value calculated thereafter and shared; avoidance value may be included in a head leasehold's core value only if it does not depend on coalescence with the enfranchising tenant or other marriage/hope mechanisms, and realistic risk must be reflected by discounts and appropriate adjustments to capitalisation and deferment rates.
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 tribunal observed (not strictly binding) that certain non-coalescing routes — notably a reversionary underlease or acquisition structured via a special‑purpose company to occupy — can be realistic avoidance mechanisms if legal advice supports that necessary consents would not be unreasonably withheld, but purchasers would apply substantial discounts; it also noted that market risk may be reflected both by capitalisation adjustments and by varying deferment rates.
