It has not been suggested that the contractual provisions providing for the payment of the $40,000 to the appellant in the present case represented a device to conceal what was in substance a payment of some other kind or were otherwise other than genuine. Traditionally, a genuine payment to an individual employee as consideration for covenants in restraint of his or her freedom to compete or to use or divulge certain information during a specified number of years after the termination of employment has not been seen as income in the ordinary sense for the purposes of s 25(1) of the Act (see, eg, FCT v Woite (1982) 31 SASR 223, at 226-7; 13 ATR 579; Dickenson v FCT (1958) 98 CLR 460, at 492; 7 AITR 257). Nor does such a payment fall within the scope of the central provisions of Pt IIIA (Capital Gains and Capital Losses) of the Act which include gains or net receipts resulting from a "disposal" (in the sense of a change "in the ownership") of an "asset" acquired on or after 20 September 1985 in the assessable income of "the person who owned the asset immediately before the disposal took place" (see, in particular, ss 160C(1), 160L(1), 160M(1) and, since 1990, s 160M(1A) and, generally, Professor Ross Parsons, "A Survey of the General Provisions of Part IIIA of the Income Tax Assessment Act", Australian Tax Forum, Vol 4, 1987, p 357, at pp 360-6 ). It is not argued on behalf of the Commissioner that the payment in the present case constituted income within the ordinary meaning of the word or that it fell within the central operative provisions of Pt IIIA. The Commissioner's argument is that, even though the transaction in the present case did not involve any "change" of ownership of any identified asset, the payment of $40,000 which the appellant received as consideration for the restraint upon his freedom to compete and to use or divulge certain information after the termination of his employment is brought within Pt IIIA by reason of the operation of s 160M(6) or s 160M(7) to produce a deemed "disposal" of an "asset" by the appellant for the purposes of that Part. On the Commissioner's argument, the $40,000 was received by the appellant as consideration for that "disposal" and is included in the taxpayer's assessable income by reason of the combined operation of the relevant sub-section and ss 160Z(1), 160ZC(1)and 160ZO(1). In the light of what has been said above about the settled principles governing the applicability of taxation provisions at least in cases not involving contrived artificialities of form, the Commissioner's submission can only be accepted if the relevant provisions of Pt IIIA of the Act express in "clear" or "plain" or "unambiguous" terms a legislative intent that they should be construed in a way which would (subject to any allowable expenses) include in the assessable income of an employee an amount received from his or her employer as consideration for covenants in restraint of his or her freedom to compete or to use or divulge certain information after the termination of employment. With due respect to those who see the matter differently, it appears to me to be plain to the point of incontrovertibility that the words which the Parliament has seen fit to use cannot properly be said to express such a legislative intent with even tolerable clarity. Indeed, when the provisions of s 160M(6) and s 160M(7) are read in the context of the other provisions of Pt IIIA, it appears to me that the preferable view is that any coherent legislative intent would probably have been to the contrary. I turn to explain why that is so.
