Self-executing rights in international human rights law are formulated in such a way that one can deduce that it was the purpose to create international laws that citizens can invoke directly in their national courts.
[citation needed] Non-self-executing rules of international law impose the obligation on states only to take measures and to create or alter legislation.
A state cannot invoke its national law as a reason not to respect its international obligations.
In case of non-self-executing rules, it is obliged to change its national law or to take certain measures.
They cannot declare national law null and void unless it contradicts self-executing international rights.
