The clergy–penitent privilege, clergy privilege, confessional privilege, priest–penitent privilege, clergyman–communicant privilege, or ecclesiastical privilege is a rule of evidence that forbids judicial inquiry into certain communications (spoken or otherwise) between clergy and members of their congregation. The law recognises certain communication as privileged and not subject to otherwise obligatory disclosure; for example, this often applies to communications between lawyers and clients. In many jurisdictions certain communications between a member of the clergy of some or all religious faiths (e.g., a minister, priest, rabbi, imam) and a person consulting them in confidence are privileged in law. In particular, Catholics are required to confess sins to priests, who are unconditionally forbidden by Church canon law from making any disclosure, a position supported by the law of many countries, although in conflict with civil law in some jurisdictions. It is a distinct concept from that of confidentiality (see non-disclosure agreement).
The protection of the clergy–penitent privilege relationships rests on one of the more basic privileges as strong or stronger than the similar clauses to confidentiality between lawyer and client.
The privilege was recognised under the common law of the Republic of Ireland as the privilege of the priest in the case of Cook v. Carroll [1945] IR 515., reversing an earlier judgment from 1802. In 2011, in the wake of several sex abuse scandals, the Fine Gael–Labour government announced plans to criminalise failure to report an allegation of child abuse, even if made during confession.Seán Brady, the Catholic primate of all Ireland, condemned this as compromising the seal of the confessional.
