I turn, now, to the major complaint, which is conveniently considered in the broad context of the law's current approach to the right of silence. Discussion of the right of silence and of the right not to incriminate oneself principally involves two issues. First, there is the question whether in a particular situation the right exists at all and, secondly, where (as is usual) it does exist, the question arises whether any adverse consequences may be permitted by the law to flow from its exercise. As to the first point, little need be said. The general law does not recognise any exceptions to the rule that it is lawful to decline to answer questions, if the answer may incriminate - indeed, the general law does not oblige citizens to answer questions at all, whether these are likely to incriminate or not. Parliaments have in some respects taken a different view; sometimes the obligation to answer questions, including incriminating questions, is made explicit, but the difficulties judges have encountered in this area have been principally concerned with statutes which have been argued to alter the general law implicitly. An interesting example is Police Service Board v. Morris [1985] HCA 9; (1985) 156 C.L.R. 397. Two policemen were charged with having disobeyed a lawful order, by refusing to answer questions when ordered to do so by an inspector; a regulation prohibited disobedience of lawful orders. The High Court held that, by the regulation, the privilege against self-incrimination was impliedly excluded; the discipline of the police force was thought to demand this result (see per Brennan J, as his Honour then was, at 413). A case having a similar tendency, in the same volume, is Controlled Consultants Pty Ltd v. Commissioner for Corporate Affairs [1985] HCA 6; (1985) 156 C.L.R. 385.
