MNR v. Mandelbaum, 62 DTC 1093 (Ex Ct) -- summary under Business

In finding that the purchase by individual shareholders of a company of mortgage receivables and conditional sales contracts owing to that company was an adventure in the nature of trade in addition to being a transaction in the course of their business of managing the company, Thorson P. stated (at p. 1098) that "if a person deals with the commodity purchased by him in the same way as a dealer in it would ordinarily do such a dealing is a trading adventure" and that "when the respondents purchased [the company's] mortgages and agreements their transaction was similar to the kind of transactions that dealers in mortgages and agreements engaged in".
