LONDON, July 25 — The right against self-incrimination, a principle that shields individuals from being forced to testify against themselves in criminal matters, is codified in legal warnings across 108 countries and jurisdictions. The concept is straightforward: self-incrimination is any statement that exposes the speaker to criminal liability, whether made under interrogation or voluntarily. Many legal systems prohibit compelling an accused person to incriminate themselves—an accused may choose to speak but cannot be punished for remaining silent.
In the European Union, member states have developed their laws around the bloc’s guiding framework. The historical origins of this privilege are a matter of scholarly dispute.
Historian Leonard Levy argued that the privilege was invented by people who had themselves been guilty of religious or political crimes. Levy connected it to the common law’s long-standing prohibition of coerced confessions, viewing the protection as originally safeguarding freedom of expression and political liberty. Other scholars have offered different accounts.
One contended that the privilege developed in the seventeenth century specifically to protect religious dissidents from inquisitorial oaths. Another argued that the privilege emerged in other courts entirely.
The extension of the privilege to modern police investigations has drawn substantial opposition. Critics have challenged its application in that context.
Divergent Approaches: Australia and Canada
Australia preserves a limited right against self-incrimination at common law, but that right is neither protected by the federal constitution nor available at the state level, where the vast majority of criminal prosecutions occur. In the 1983 case Sorby v Commonwealth, the High Court of Australia affirmed that the privilege could only be abrogated by explicit statutory provisions.
Several federal statutes have done precisely that: legislation governing the Australian Crime Commission, the Australian Competition and Consumer Commission, the Australian Security Intelligence Organisation, and the Australian Securities and Investments Commission each require individuals to answer truthfully, with no exemption for self-incriminatory statements. Canada provides a more layered protection.
Section 11(c) of the Charter of Rights and Freedoms guarantees that any person charged with an offence has the right not to be compelled to be a witness against themselves. However, a person who is issued a subpoena and has not been charged must still give testimony. In such cases, Section 13 of the Charter prevents that incriminating evidence from being used against the witness in other proceedings—except, notably, in a prosecution for perjury.
The varying national approaches reflect the ongoing tension between the rights of the accused and the state’s interest in obtaining evidence. With 108 jurisdictions now issuing formal warnings about the right to remain silent, the debate over how far that privilege should extend—especially into areas such as regulatory investigations and compelled testimony—shows no sign of resolution.
The coming years are likely to see further legal contests over the boundaries of this ancient safeguard.
