Construction of the undertaking
- Rule 39.21(1) of the Rules provides:
A party may apply to the Court for an order requiring a person to do, or refrain from doing, an act or thing, including payment of a sum of money, if:
- the person (whether a party or not) has given the Court an undertaking to do, or refrain from doing, the act of thing; and
- the person has failed to fulfil the undertaking.
- On such an application, the Court must determine "whether it has been shown that [the person] [has] failed to fulfil the undertaking, properly construed, and, if so, whether the relief claimed should be granted": International Hair Cosmetics Group Pty Ltd v International Hair Cosmetics Ltd [2011] FCA 339; 218 FCR 398 (Logan J) at [44].
- I accept that, in circumstances where such an undertaking is part of an order of the Court agreed by consent, evidence of surrounding circumstances is admissible for the purpose of construing the undertaking: International Cosmetics at [49]-[50]; Nokia Corporation v Liu [2009] FCAFC 138; 179 FCR 422 (Finn, Sundberg and Edmonds JJ) at [29]-[31]. That does not displace, however, the usual principles relevant to the construction of such an undertaking, it being accepted that the principles relevant to the interpretation of contracts provide appropriate guidance: CCOM Pty Ltd v Jiejing Pty Ltd [1992] FCA 519; 36 FCR 524 (Drummond J) at 527. Consequently, unless the undertaking is ambiguous or capable of more than one meaning, it will not be appropriate to have recourse to evidence of surrounding circumstances: Repatriation Commission v Nation (1995) 57 FCR 25 (Beaumont J, Black CJ and Jenkinson J agreeing) at 34,
[u]nder the ordinary rules of construction, evidence of surrounding circumstances is admissible to assist in [construction] of an instrument if the language is ambiguous or susceptible of more than one meaning, but not admissible to contradict the language of the instrument when it has "a plain meaning" (see Codelfa Construction Pty Ltd v State Rail Authority (NSW) (1982) 149 CLR 337 per Mason J at 352).
