, 1.1. Approaches to the Application of International Law in South Africa
The application of international law within a state's domestic legal system is generally
understood through two primary theoretical approaches: monism and dualism. These
theories define the relationship between international and municipal law, influencing
how international norms acquire legal force domestically. South Africa, like many states,
has adopted a hybrid approach that incorporates elements of both, reflecting a nuanced
engagement with international legal obligations.
Monism
In a monist system, international law and domestic law are considered part of a single,
unified legal order. This means that international law, once it comes into existence,
automatically becomes part of the domestic legal system without the need for specific
domestic implementing legislation. International legal norms are directly applicable by
national courts and can, in principle, override conflicting domestic law, although the
precise hierarchy can vary. The core idea is that international law is inherently superior
or at least equal to national law.
Dualism
Conversely, dualist systems view international law and domestic law as two distinct and
separate legal orders. For an international treaty or customary international law to have
effect within the domestic legal system, it must first be transformed or incorporated into
national law through specific legislative acts. Until such domestic legislation is passed,
international law does not create rights or obligations enforceable in national courts.
This approach emphasizes state sovereignty, requiring a deliberate act by the domestic
legislature to consent to the application of international norms within its borders.
