(iii) in chambers in accordance with rule 6 …"
50 In Palmer v Clarke at 165, Kirby P pointed out the need for strict compliance with the statutory framework. The 'slip rule' aside, there is nothing in the District Court Act 1973 (NSW) or Rules, and in particular nothing in r 7 which permits the revision of judgments by a judge of an inferior court, although it is a well used convention. It was not suggested in this case that the slip rule applied. Although there is no direct authority on point and no express power in the Act or Rules conferring the right to revise judgments, it would be strange if there was such a rule in relation to ex tempore judgments and none in respect of reserved judgements given orally, where the same infelicities of expression and the like may easily occur. Accordingly, I am of the view that there is a power to revise a judge's reasons for decision, within the parameters I have discussed, implied within the statutory provisions which govern the delivery of judgments in the District Court. As to the existence of implied powers of statutorily governed tribunals: see DPP v Shirvanian (1998) 44 NSWLR 129.
51 How then should the addition of his Honour's finding on Mr Fefelov's credit be categorised. On one view, the addition could be seen as a mere formality - something overlooked by the trial judge when giving his oral reasons. The finding did not change his Honour's ultimate finding. Rather, it was wholly consistent with it and therefore, it could be argued, could not have come as a surprise.
52 There are arguments which tend to the opposite conclusion. In the first place, it was a critical finding. The rejection of Mr Fefelov as a witness of truth was an essential underpinning of his Honour's finding against the appellant. Secondly, had that finding not been made, the appellant could have rightfully complained that his Honour had failed to adequately consider relevant evidence in the case, namely, that of his corroborative witness. Those two matters alone, in my view, point persuasively to the additional statement in the judgment being one of substance and therefore impermissible.
53 Where a judgment has had impermissible alterations made to it, the proper approach is to treat the judgment as if the additions had not been made: see Palmer v Clarke at 170. Accordingly, the judgment should be considered as if that finding was not contained in it. The consequence is that his Honour's reference to Mr Fefelov's evidence went no further than saying he gave evidence which corroborated the appellant's evidence. I have already indicated what flows from that. His Honour failed to give it adequate consideration in its essential parts and/or failed to give adequate reasons for decision.
54 If I am wrong in my conclusion that the credit finding relating to Mr Fefelov was one of substance, and it should be viewed as a matter of form and thus remain as part of the judgment, I am of the opinion that his Honour's judgment would still not satisfy the requirement to give adequate reasons for decision. As Kirby P pointed out in Palmer v Clarke at 170:
"… bald findings on credit, where there remain substantial factual issues to be dealt with, may not constitute an adequate compliance with the judge's common law duty to provide the parties, and the appellate court, with the basis of his decision."
55 In this case it is impossible to discern why his Honour rejected Mr Fefelov, although one might speculate that it was to make his judgment consistent, given his finding in relation to the appellant's credit. However, it is not part of the judicial function to speculate. At the appellate stage it is to determine whether there has been appealable error. For the reasons stated, his Honour's bald finding of credit involved such error.
