Before affirming a finding below that the appellant partnership, which had been licensed rights to exploit two films, was not carrying on a trade but instead had "non-trade business," Sales J stated (at paras. 78-79):
[78]…[A]n element of speculation in the sense of conducting an activity which might result in a profit or a loss is strongly indicative of that activity being capable of having the character of trading, and the absence of such an element is strongly indicative that it is not a trading activity.
[79] That interpretation is also supported by the way in which 'trade' was defined at the relevant time and has been defined in tax legislation for a long time, as including 'every trade, manufacture, adventure or concern in the nature of trade' (see e.g. section 832(1) ICTA 1988, set out at [398]). In a list of terms like this, the meaning of each item naturally takes some colour from those listed with it. In old legal language, the 'nosçitur a sociis' principle is relevant: the meaning of a term is given or informed by its fellow terms deployed in the same list. Here, the use of the word 'adventure' is redolent of business activity of a speculative kind, and this informs the meaning to be given to 'trade'.
