RP Explorer Master Fund v Chilukuri and another [2013] EWCA Civ 1307, [2013] All ER (D) 341 (Oct)
In any complicated process of valuation (in the instant case, valuation of shares as part of calculating damages in a case based on breach of contract), the valuer had to take the relevant aspects of the world as he found them (unless constrained by his instructions), and he had, after looking at each element of the process, to stand back and ask himself whether his provisional valuation made commercial or business sense, viewed in the round.
