Key legal question
Whether the profits from the sale of the terraced houses are taxable as income from self-employment/business assets.
Extracted holding
Yes. The property project amounted to a profit-oriented real estate dealing activity starting in 1972, so the sale gains were taxable.
Extracted reasoning
The purchase of undeveloped land, construction of an extensive terrace development using significant borrowed funds, later professional parceling and brokerage, and the phased disposal of units showed activity beyond mere private wealth management.
