Longmore L. J. said,
’25. The matter does not of course rest there because when alternative constructions are available one has to consider which is the more commercially sensible…
26. The Judge said that it did not flout common sense to say that the clause provided for a very limited level of release, but that, with respect, is not quite the way to look at the matter. If a clause is capable of two meanings, as on any view this clause is, it is quite possible that neither meaning will flout common sense. In such circumstances, it is much more appropriate to adopt the more, rather than the less, commercial construction.’
