The Court made several significant obiter observations: (1) On statutory interpretation: Courts must ascertain legislative intention from clear and unambiguous language; in fiscal legislation, if a taxpayer falls within the letter of the law, they must be taxed regardless of hardship, but ambiguities are resolved contra fiscum. (2) On the relationship between parent legislation and regulations: Regulations are subordinate to their parent Act and cannot vary or determine the interpretation of the Act; "the tail cannot wag the dog." (3) On retrospective legislation: There is no constitutional prohibition on Parliament imposing financial obligations retrospectively through civil legislation, including tax laws. The retrospective enactment of s 10(2)(q) in 2015 (effective 1 January 2004) was constitutionally valid. (4) On validity of regulations: Section 15 of the original VAT Regulations, though enacted before s 10(2)(q) existed, was not invalid but merely inoperable until the parent provision was retrospectively enacted. There is a presumption of validity for statutory instruments until struck down by a competent court. (5) On tourism industry practices: The Court recognized the "worldwide tourism industry pricing model" involving rack rates and net effective rates as an established commercial practice, but held this did not alter the tax treatment. (6) On penalties: The Court would apply a triad of considerations (the offence, the offender, and societal interests) and found a 20% penalty appropriate where there was no intent to evade but there was some moral blameworthiness in failing to recognize the tax implications of commercial arrangements. (7) On procedural fairness: The Court criticized the late raising of the preliminary point (4 days before hearing) but noted that points going to jurisdiction can be raised at any time, even on appeal, if they involve no unfairness.
