Madzimbamuto v Lardner-Burke

Facts

In November 1965 the Southern Rhodesian government under Ian Smith made a unilateral declaration of independence from the United Kingdom. The United Kingdom Parliament responded with the Southern Rhodesia Act 1965, which declared that Southern Rhodesia remained part of Her Majesty's dominions and that the Westminster Parliament retained responsibility and jurisdiction for the territory. Madzimbamuto, a political opponent of the regime, was detained under emergency regulations made by the Rhodesian government under the purported new constitution. His wife challenged the detention.

History

The Rhodesian High Court and its Appellate Division upheld the detention on the basis that the regime had become the de facto government. An appeal was brought to the Privy Council.

Issue

Whether the Southern Rhodesia Act 1965 was effective to deprive the Rhodesian legislature and government of authority, whether the emergency regulations were valid as the acts of a de facto government, and whether the detention was lawful.

Held

The Privy Council advised that the appeal be allowed and that the detention was unlawful. The Rhodesian regime was not the lawful government, the 1965 Act was effective, and the doctrine of necessity did not validate the regulations.

Ratio

• The United Kingdom Parliament retained sovereignty over Southern Rhodesia, and legislation passed by Westminster for the territory was effective in law whatever conventions might exist, so the regime set up by the unilateral declaration was not the lawful government.
• The acts of a usurping de facto government can in some cases be treated as valid on grounds of necessity to maintain order, but not where they serve the aims of the illegal regime, and the regulations under which the detention was ordered did not qualify.

The judgments

Key reasoning

• The Rhodesian courts had no power to recognise the regime as the lawful government in the face of the clear statement of Westminster's authority in the 1965 Act, and effective control alone does not confer legal authority.
• A constitutional convention that the United Kingdom would not legislate for Rhodesia without its government's consent was not a rule of law, and the courts could not hold the Act invalid for breach of it.
• A doctrine of necessity might preserve some acts of the de facto authorities, such as routine administration, to prevent lawlessness, but it could not extend to measures designed to entrench the unlawful regime.

Obiter

• Lord Reid said that it is often said to be unconstitutional for Parliament to do certain things, because the moral and political reasons against doing them are so strong, but that this does not mean they are beyond its legal power, and if Parliament chose to do them the courts could not hold the legislation invalid.

Where it fits in the module

Madzimbamuto is used in the study of parliamentary sovereignty and constitutional conventions. It supports the orthodox view that courts enforce legislation regardless of constitutional conventions, and it contributes to the debate on whether Parliament can legislate for other territories and the fate of acts by regimes that seize power. It sits with later debates about whether sovereignty has any limits and the relationship between law and political fact.

Criticisms

• The statement that Parliament can do anything the courts must enforce rests on the assumption that sovereignty is a fact of legal recognition, which begs the question of the source of the rule.
• The doctrine of necessity as applied by the majority leaves unclear which acts of a usurper are valid and which are not, and so draws a line that is hard to apply.
• The advice was given to a court that could not enforce it, which illustrates the gap between legal and effective authority and the limits of judicial pronouncements on political crises.
