"(1) For the purposes of this section - 'Arrangement' means any contract, agreement, plan or understanding (whether enforceable or unenforceable) including all steps and transactions by which it is carried into effect: 'Liability' includes a potential or prospective liability in respect of future income: 'Tax avoidance' includes (a) Directly or indirectly altering the incidence of any income tax: (b) Directly or indirectly relieving any person from liability to pay any income tax: (c) Directly or indirectly avoiding, reducing or postponing any liability to income tax. (2) Every arrangement made or entered into, whether before or after the commencement of this Act, shall be absolutely void as against the Commissioner for income tax purposes if and to the extent that, directly or indirectly – (a) Its purpose or effect is tax avoidance; or (b) Where it has 2 or more purposes or effects, one of its purposes or effects (not being merely an incidental purpose or effect) is tax avoidance, whether or not any other or others of its purposes or effects relate to, or are referable to, ordinary business or family dealings,- whether or not any person affected by that arrangement is a party thereto. (3) Where an arrangement is void in accordance with subsection (2) of this section, the assessable income … of any person affected by that arrangement shall be adjusted in such manner as the Commissioner considers appropriate so as to counteract any tax advantage obtained by that person from or under that arrangement …"
"... it is inherent in the section that, but for its provisions, the impugned arrangements would meet all the specific requirements of the income tax legislation."
"The material distinction in the present case is between tax mitigation and tax avoidance. A taxpayer has always been free to mitigate his liability to tax … Income tax is mitigated by a taxpayer who reduces his income or incurs expenditure in circumstances which reduce his assessable income or entitle him to reduction in his tax liability… Section 99 does not apply to tax mitigation where the taxpayer obtains a tax advantage by reducing his income or by incurring expenditure in circumstances in which the taxing statute affords a reduction in tax liability. Section 99 does apply to tax avoidance. Income tax is avoided and the tax advantage is derived from an arrangement when the taxpayer reduces his liability to tax without involving him in the loss or expenditure which entitles him to that reduction. The taxpayer engaged in tax avoidance does not reduce his income or suffer a loss or incur expenditure but nevertheless obtains a reduction in his liability to tax as if he had"
"The hallmark of tax avoidance is that the taxpayer reduces his liability to tax without incurring the economic consequences that Parliament intended to be suffered by any taxpayer qualifying for such reduction in his tax liability … But it would be absurd in the context of [the provision there affording relief from tax] to describe as tax avoidance the acceptance of an offer of freedom from tax which Parliament has deliberately made."
"… section 99 would be a dead letter if it were subordinate to all the specific provisions of the legislation. It, too, is specific in the sense of being directed against tax avoidance ... while the use [of trusts and companies] is regarded as perfectly legitimate and not on its own affected by section 99, it may be only one element in a wider arrangement which is caught by the section."

"The tax treatment which applies to these films is: No distinction is drawn between investors in films and those persons who are engaged on a full time basis in the business of producing or distributing films. Each is entitled to offset his/her share of the costs of producing or marketing the film against income from the film and income from other sources … Non-recourse loans are treated in the same manner as normal commercial loans … costs of producing films are not deductible in the year incurred. Instead, they must be capitalised and depreciated at the rate of 50 per cent on cost price."
