At a later stage, counsel refined the objection to that of general fairness and impermissible cross-examination. Although the particular objection was subsequently withdrawn there remains the general objection based on the question of cross examination.The questions were designed to examine the circumstances surrounding the making of the previous inconsistent statement. Accepting that they constituted cross-examination, it does not follow that they are impermissible. There are a number of exceptions to limits placed on cross-examination of an accused person. Those exceptions include propensity (Makin v Attorney-General for New South Wales [1894] AC 57, Attwood v The Queen [1960] HCA 15; (1960) 102 CLR 353), character (Crabbe v R [1984] FCA 321; (1984) 56 ALR 733), questions arising out of imputations on the character of Crown witnesses (Evidence Act 1910, s85 (1)(c), Curwood v R (1944 - [1944] HCA 40; 1945) 69 CLR 561, Phillips v R [1985] HCA 79; (1985) 159 CLR 45) and matters involving evidence relevant to or on behalf of a co-accused (Matusevich v R (1976 - [1977] HCA 30; 1977) 137 CLR 633) although in many instances leave of the court is required (R v Saric [1982] Qd R 360). Accepting that exceptions are permitted to the general rule limiting cross-examination, there is no reason why an exception should not be permitted in an examination as to whether a witness should be regarded as hostile provided that the questions are confined to the issue requiring determination. To that extent, the differing principles in governing impeachment and cross-examination coincide. A trial held on the voire dire is concerned with the issue of hostility and to that limited extent, the witness whose evidence is sought to be impugned can be regarded as a potential witness for the opponent. The issue is between the party and the witness and although an opponent should be afforded the right of intervention by way of cross-examination or recalling of evidence, the central issue remains one of the evidentiary status of the witness. In the trial of that issue, the party ought be permitted the right to ask leading questions and, where there is inadequate response, to pursue the matter by way of cross-examination provided such cross-examination is confined to the existence of inconsistency and the reasons thereof. Such an approach neither offends the provisions of the Act, s97, nor is contrary to permitted exceptions to the rules limiting cross-examination. That right and the appropriate procedure to be followed before a declaration of hostility was stated by Dixon J in R v Neal, Regos and Morgan (noted in [1947] ALR 616), a decision applied by the Full Court of the Supreme Court of Victoria in R v Thynne (supra). The course adopted in Neal was stated in Thynne at 101 in the following terms:
