As fundamental as the right to freedom of expression, it is not and cannot be absolute. The limitations have been listed below:
- State Privilege
This is said to be “the right of the state through its agents or functionaries to withhold evidence which it considers could, if revealed in open court, adversely affect the public interest.” Evidence Act prohibit disclosure of unpublished official documents except with the permission of the head of the department concerned; disclosure of communication made in official confidence when considered not in public interest; production of documents in the possession of a public officer which may any other person would be entitled to refuse to produce if in his possession unless such a person consents.
- Official Secret
- Contempt of Court
In the course of the administration of justice by the courts there is no doubt about the need to ensure improper interference and obstruction. Contempt can be civil or criminal. Criminal contempt as it applies to the freedom of expression involves actions that can interfere with the administration of justice. Contempt proceeding is usually invoked here for deterrent and punishment. Our media practitioners should avoid:
- Publications prejudicial to a fair criminal trial;
- Publications prejudicial to a fair civil trial;
- Scandalizing the court;
- Contempt in the face of the court;
- Acts which interfere with the course of justice.
- Obscene and harmful publications
The major restriction of obscene and harmful publications is in the interest of public morality. Forms of obscene publication include pornography, erotic realism, and other erotica.
Defamation can be a statement which reflects on person’s reputation and tends to lower him in the estimation of right-thinking members of the society generally or tends to make them shun or avoid him.  It is defamatory when the publication tends:
- To lower the person in the estimation of right thinking members of the society generally; or
- To expose him to hatred, ridicule or contempt; or
- To make others shun or avoid him; or
- To discredit him in his office, grade or profession; or
- To injure his financial credit.
Kindly note, that defamation can be civil and criminal in nature. Criminal defamation as enshrined in the criminal code provides that:
…matter likely to injure the reputation of any person by exposing him to hatred, contempt or ridicule, or likely to damage any person in his profession or trade by an injury to his reputation.
Before any person can raise defamation issue, the following must have happened:
- The words must be defamatory;
- The words must refer to the person challenging defamation
- The words must be published.
Kindly note that defamation can occur either in libel, which is publication of defamatory statement in permanent form such as in print, online or in written form. It can also be a slander, which can be spoken words, conduct or other translator form.
Finally, generally under the law of tort, justification is a defence to defamation. If the words complained of were true in substance, it is a complete defence in a defamation action.
