The seal of the confessional is often described as ‘inviolable’. The idea that what is said or done in furtherance of private confession may be subjected to scrutiny as part of litigation is often considered to be absurd. But what is the legal basis for such forthright rejection? The revised Canons of the Church of England do not address the issue at all; instead the matter falls to be covered by the unrepealed proviso to Canon 113 of the Code of 1603. In England and Wales there is no primary legislation which clearly and coherently deals with the question of the admissibility of matters said in private confession before courts and tribunals. Contrast that with the United States of America, where every single state has enacted statutory provisions which provide safeguards to admissibility, albeit to differing degrees. Recent developments in Australia have, conversely, involved the enactment of legislation making it a crime for a priest to withhold, in certain circumstances, matters said to him or her in the course of private confession. In 1990, Judge Bursell QC reviewed the existing case law on the subject (sparse though it is) and found it to be contradictory, with judgments appearing to be based upon personal opinions as opposed to legal analysis. There have been some interesting ‘post-Bursell’ developments, in terms of both legislation and case law, which are discussed in this article. In Ecclesiastical Law, Mark Hill QC suggests that ‘it is likely that a trial judge would exclude evidence of a confession made to a priest’. This article is essentially an analysis of that conclusion with a view to determining whether it is right to assume that, even if not adequately protected by legislation, things said or done in furtherance of private confession are likely to be excluded from secular criminal proceedings.
