The Valuation of Land Act 1916 (NSW) does not prescribe the comparable sales method or any particular methodology for conducting it; the four-step process from Marroun v Roads and Maritime Services [2012] NSWLEC 199 is not required as a matter of law. A judicial valuer may calculate the median and average of adjusted rates derived from comparable sales to inform (but not fix) the land value without committing an error of law. Alleged errors in 'valuation principle' derived from case law of other jurisdictions do not constitute errors on questions of law unless they contravene the terms of the Valuation of Land Act itself.
