“Subject to subsection (4) below, the payment required under this section in respect of any damage is a payment equal to the cost reasonably incurred by any person [i.e. other than the Authority] in executing remedial works.”
“Where remedial works are executed after the end of the period of three years beginning with the date of the claimant’s damage notice, the amount of any payment under subsection (3) above shall not exceed the cost which might reasonably have been expected to have been incurred in executing those works if they had been executed immediately before the end of that period.”
“Further or in the alternative, the Claimant’s reference has not been made within the period required pursuant to s.44(2) of the 1991 Act, and the claim is accordingly statute barred.”
“No question to which this section applies shall be heard and determined by any tribunal …unless the necessary reference is made … before the end of whichever of the following periods last expires, namely – (a) the period of three years beginning with the earliest date on which [the Authority] are in breach of their remedial obligation; and (b) the period allowed by section 3 above for giving a damage notice …( the period of six years beginning with [the first date on which any person entitled to give the notice had the knowledge required for founding a claim (see s. 3(3))]”
“The phrase ‘losses or outgoings’ in the Australian section is to be compared with the word ‘expenditure’ in the New Zealand section. ‘Expenditure’ is defined in The Shorter Oxford English Dictionary as ‘The amount expended from time to time’ and the meaning of ‘expend’ is given as ‘To pay away, lay out, spend’. In the New Zealand section the word ‘expenditure’ is linked with the word ‘incurred’, as is the phrase ‘losses or outgoings’ in the Australian section. For that reason, notwithstanding the citation made by McGregor J. from Kekewich J., I think the reasoning of the High Court [of Australia] should be applied to the construction of s.121. Accordingly I think that a deduction may be allowed under that section in respect of ‘expenditure incurred’ although there has been no actual disbursement if, in the relevant year, the taxpayer is definitely committed to that expenditure.”
