Principles governing amendments
95 The power of the Court to amend is contained in s 170 of the Act and r 148 of the Industrial Relations Commission Rules 1996. As the respondents acknowledged, the Court usefully summarised the principles relating to amendment of pleadings in Judgment No. 15 at [52]-[57] and, as well, the respondents accepted the correctness of the applicants' summary of the principles which, I consider, is worth reproducing:
The power to amend may be exercised " at any stage of any proceedings " (see section 170(2)(a) of the Act and rule 148(1) of the Rules; see also Decision No 15 at [52]). Consistent with the position under general law (see National Australia Bank Limited v Nobile (1988) 100 ALR 227 at 235; TCN Channel 9 Pty Limited v Antoniadis (1998) 44 NSWLR 682 (" TCN Channel 9 ") at 695), the power may be exercised as after the evidence has closed and even after the delivery of judgment (see Decision No 15 at [57]; Mercantile Mutual Insurance v Farrington (1996) 44 NSWLR 634 at 648F-651F). In TCN Channel 9 , the Court of Appeal said (at page 695B-695C) that:
"There being no legal objection to the proposed contextual imputations, the finding that Channel Nine did not rely on any new facts to support them was a compelling reason for allowing the amendment. An amendment which reformulates a claim or defence within a cause of action or defence which has already been pleaded, based on evidence that has been or will be adduced, should ordinarily be allowed in order to raise the real questions and issue between the parties. Such an amendment should be allowed even after the evidence has closed. This is not a new principle as can be seen from Clough v London and North Western Railway Company (1871) 7 Ex 26 at 30 and it was emphatically endorsed by Stephen J, Mason J and Jacobs J in Leotta v Public Transport Commission (NSW) (1976) 50 ALJR 666 at 668; 9 ALR 437 at 446, and by this Court in Commonwealth v McLean (1996) 41 NSWLR 389 at 397-398" (Underlining added)
Decision No 15 itself involved this Court permitting the Applicants to further amend the Third Summons after the evidence was closed and after the Court had delivered its decision in Gough & Gilmour Holdings Pty Limited & Ors v Caterpillar of Australia Limited & Ors [2002] NSWIRComm 354 (19 December 2002) (" Decision No 11 ") (see also Gilbertson v South Australia (1976) 15 SASR 156 at 159 generally; FF Seeley Nominees Pty Limited v El Ar Initiations (UK) Limited (No 41) (1990) 55 SASR 314; Sherpa v Anderson (unreported, Supreme Court of NSW (Young J), 14 October 2003, BC9302148) at page 3.5 and 5.2 of the Internet print; see further Decision No 15 at [16]-[19], [64]-[66]).
The power to amend is to be exercised in such manner as the Court considers " to be necessary in the interests of justice " (see section 170(1) of the Act and rule 148(1) of the Rules; see also Decision No 15 at [52], [55]). The consideration of " justice " reflects the position under the general law (see Queensland v J L Holdings Pty Limited (1997) 189 CLR 146 (" J L Holdings ") at 155, 167, 172; see also Macquarie Bank Limited v National Mutual Life Association of Australia Limited (1996) 40 NSWLR 543 at 554). In J L Holdings (at 153), the majority cited with approval the following passage from Clough and Rogers v Frog (1974) 48 ALJR 481 at 482 wherein the High Court said:
"As the defence, if established, would be a complete answer in either action, the amendments sought should have been allowed unless it appeared that an injustice would thereby have been occasioned to the respondent, there being nothing to suggest fraud or improper concealment of the defence on the part of the appellants. With the exception of the suggestion of prejudice arising in respect of the loss of the possible claim against the nominal defendant, the matters relied upon by the respondent in opposition to the amendment sought go at the most to delay and irregularity only, matters which are relevant to costs but do not constitute injustice to the respondent in the sense in which that expression is used " (underlining added).
