Right to Silence: Criminal Law

The privilege against right to silence and self-incrimination go hand in hand. They are also very closely related to the presumption of innocence. As the responsibility is placed on the prosecution to prove the guilt of a person it follows that the accused should not be forced to assist the prosecution by being forced to speak.

First of all I will look at the right to silence at the pre-trial stage that is while a crime is being investigated, but before a person has been charged with that crime. However at common law, it was clear that suspects enjoyed a right to refuse to answer police questions. Whereas recent legislation has increasingly tended to require answers to be given in specific circumstances, or allow the court to draw an adverse inference from the failure to give answers.

However it is important to note that, where no such legislation has been enacted, then the right to silence remains available. An example of this can be seen in People (DPP) v Finnerty. Where the defendant was accused of rape and put forward an alternative account of the events on the night in question. In response the prosecution sought to put it to the defendant that he had not given any such account when arrested and questioned. The trial judge allowed the prosecution to question the defendant on his silence when arrested and the defendant was therefore convicted. However on appeal, the Court of Criminal Appeal upheld this decision, Stating that it didn’t impinge on the defendants right to silence, in as much as it was limited to the credibility of the defendants account of events and was not in itself evidence of guilt.

Moving to the trial of right to silence itself, it is clear to see that there is a constitutional right of an accused person, arising from the Article 38.1, to refuse to testify. However if an accused person does choose to testify, he then waives that right. He must answer questions put to him or her by the prosecution, they cannot define to do on the basis that the answers would incriminate him; Criminal Justice (Evidence) Act 1924, section 1 (e).

As you can see that legislation may validly require a person to answer questions connected with a criminal investigation. However fact is that a person may be compelled to answer does not necessarily mean that any information which they give can be used in evidence against them at trial, and the questions must be asked as to whether the privilege against self-incrimination will prevent such use.

This issue came in the Supreme Court in Re National Irish Bank. This case concerned section 10 of the Companies Act 1990, which imposed an obligation on company officers and agents to co-operate with inspectors investigating a company.

In Heaney v Ireland, the Supreme Court ruled that the right to silence is a constitutional right protected by Article 40.6 of the Constitution as a corollary to the right of free expression. However the Supreme Court also stated that the Constitutional right to silence only implied to anything that might offer the police evidence, which was self-incriminating. In other words the Constitutional right to silence could not extend to not answering police questions that would not involve self-incrimination such as providing your name and address when asked or providing your date of birth or nationality when asked as this information would not normally be self-incriminating.

The European Court of Human Rights in Quinn v Ireland, while acknowledging that the right to silence and the right not to incriminate oneself as laid out in Article 6 of the European Convention for the Protection of Human Rights and Fundamental Freedoms was not an absolute right, it felt that section 52 went further than was necessary to meet the needs of the state. However, it seems from more recent decisions of the courts in Ireland that once any such evidence relating to a failure or refusal under section 52 is not used in the prosecution case against ...
