1. Expenditure incurred to relocate third-party infrastructure and a residential township pursuant to requirements in a Mining Work Programme forming part of a mining right, to enable optimal mining and comply with safety regulations and anticipated legal obligations, constitutes capital expenditure "incurred in terms of a mining right" within the meaning of s 36(11)(e) of the ITA. 2. The reference to "infrastructure" in the exclusion in s 36(11)(e) refers to infrastructure owned by and forming part of the income-earning structure belonging to the taxpayer, not infrastructure owned by third parties or compensation paid to third parties. 3. Electricity supply lines that are integral to operating mining equipment constitute "mine equipment" for purposes of s 36(11)(a) of the ITA. 4. Expenditure to relocate electricity supply lines to enable mining equipment to operate in new locations as mining progresses constitutes revenue expenditure deductible under s 11(a), being closely connected to income-producing operations and likely to recur, rather than capital expenditure. 5. Legal expenditure incurred to provide legal advice to third parties affected by a taxpayer's operations, even if indirectly related to the taxpayer's business operations, is not deductible under s 11(c) or s 11(a) where it is not incurred for the taxpayer's direct benefit and is not sufficiently closely related to the taxpayer's trade. 6. In determining whether expenditure is capital or revenue in nature, courts should apply a common-sense approach examining all relevant factors including the purpose of the expenditure, its closeness to income production, whether it is once-and-for-all or recurring, and whether it creates an enduring benefit, with no single test being determinative.
