(b) conclusive evidence that the amount and all particulars of the assessment are correct, except in objection or review proceedings when it is prima facie evidence only."
27 Exhibit P4 was issued after the Commissioner had been provided with the Terms, inter alia, and had been asked to give a determination on whether any further duty was payable in respect of the transaction. Exhibit P4 gives such determination and is, therefore, a "notice of assessment" that there is "not a particular tax liability" in respect of the Terms or otherwise in respect of the transaction. By reason of s.119 coupled with s.16, the Defendants cannot, in these proceedings, challenge the correctness of that assessment.
28 It might be said that, because the purpose of the Duties Act and the Administration Act is the raising of revenue, s. 16 and s.119 should be construed as having conclusive effect only as between the taxpayer and the Commissioner so that a third party, such as the Defendants in these proceedings, is at liberty to challenge an assessment of duty in order to invoke the provisions of s.304 of the Duties Act . I cannot think that such a proposition could be correct.
29 In my view, s.119 makes a notice of assessment conclusive evidence of the matters stated for all purposes between all persons; the only exception is as between the taxpayer and the Commissioner for the purpose of an objection or a review proceeding. This is so because the purpose of the Duties Act and the Administration Act is manifestly to impose, and to collect as effectively as possible, a tax for the benefit of the State. Those Acts have nothing to do with the adjustment of private rights amongst citizens of the State. Section 304 of the Duties Act and its various predecessors affect the conduct of litigation between parties, not for the benefit of any of the parties, but in order to secure the effective collection of revenue by the State in accordance with the taxing legislation. Once the requirements of the taxing legislation have been fulfilled to the satisfaction of the revenue authority the Court has no further concern to scrutinise the transaction in the interests of a party to litigation who wishes to deprive an instrument of legal effect.
30 This has been the attitude of the Courts from the earliest times. The distant progenitors of s.304 of the Duties Act are s.11 of 5 Will. & M. c.21 and s.59 of 9 & 10 Will. 3 c.25. As to those provisions, Lord Eldon said in Huddleston v Briscoe (1805) 11 Ves 583, at 595 [32 ER 1215, at 1219]:
"If the agreement is one, upon which no action is to be brought unless it is stamped, it must be stamped before action brought: but if it is an agreement, which you may get stamped, paying the penalty, there pending the action it may be stamped; and a cause has been allowed to stand over here upon that distinction. The consequence is, that, if the Court is not to act, where there has not been an observance of the revenue laws, neither is it to turn the party round, if, before the suit is over, those laws are complied with."
