KembaraXtra – Legal Terms – Prescribed by Law
The expression prescribed by law is a fundamental requirement under the European Convention on Human Rights whenever a public authority interferes with a protected right or freedom. Under the Convention, rights such as freedom of expression, privacy, liberty, and peaceful assembly may only be restricted where the interference is authorized by law. This principle ensures that governmental power is exercised according to clear legal rules rather than arbitrary discretion. A restriction imposed without legal authority will generally violate the Convention. The concept therefore forms an important safeguard against unlawful state interference with individual rights.

For an interference to be prescribed by law, there must first exist a legal framework governing the action in question. The law must be adequately accessible so that individuals can discover and understand the rules affecting them. Citizens should be able to determine, with appropriate legal advice if necessary, whether particular conduct may expose them to restrictions or penalties. Secret, vague, or inaccessible rules are inconsistent with the Convention standard. The requirement therefore promotes legal certainty and transparency within democratic societies.

In addition to accessibility, the law must also be formulated with sufficient precision. Individuals must be able to regulate their conduct by understanding the consequences that may follow from particular actions. Laws granting excessively broad or undefined powers to public authorities may fail this requirement because they create the risk of arbitrary enforcement. The principle was explained in Sunday Times v United Kingdom, where the court emphasized the importance of clarity and foreseeability in legal rules. Precision in legislation therefore serves as a protection against abuse of governmental power.

The prescribed by law requirement applies across many different areas of public law and human rights litigation. It is relevant to surveillance powers, criminal offences, restrictions on protests, censorship, detention, immigration control, and numerous other governmental actions affecting individual freedoms. Courts assessing compatibility with human rights standards must examine not only whether legal authority exists but also whether the law itself satisfies the standards of accessibility and precision. This ensures that interference with rights is subject to genuine legal control rather than unchecked executive discretion. The doctrine therefore reinforces the rule of law within constitutional systems.
​

Ultimately, the principle that restrictions must be prescribed by law reflects the broader constitutional value that government itself must act according to law. Public authorities cannot interfere with fundamental rights merely because they consider such interference desirable or convenient. Instead, their actions must be justified by clear legal rules enacted and applied within a lawful framework. The doctrine protects individual freedom, promotes predictability, and strengthens accountability in democratic governance. As a result, it remains one of the central principles underlying modern human rights law.
