(c) Permissible extent of derogations
Any derogation under article 4 (1) of the Covenant may only be “to the
extent strictly required by the exigencies of the situation.”
Key to this
requirement is the temporary nature of any derogation. The Human Rights
Committee has said that the restoration of a state of normalcy where full
respect for the Covenant can again be secured must be the predominant
objective of a State party derogating from the Covenant. Any measure
derogating from the Covenant must be necessary and proportional.
Article 4 (1) specifies that any derogation of rights in times of emergency
may not involve discrimination solely on the ground of race, colour, sex,
language, religion or social origin. It also provides that any derogating
measures must not be inconsistent with the derogating State’s
obligations
under international law, which would include obligations
under
international human rights, international humanitarian law and
international criminal law. Article 5 (1) is of relevance as well. It clarifies
that nothing in the Covenant (including the article 4 ability to derogate)
can be interpreted as implying any right to engage in activity aimed at the
destruction of the rights and freedoms set out in it.
Finally, as with limitations described above, any derogation must comply
strictly with the principles of necessity and proportionality.
