Problem is that for example USA doesn't follow it.
Guantanomo Bay clearly violated articles 8,9 and 11.
Article 8.
Everyone has the right to an effective remedy by the competent national tribunals for acts violating the fundamental rights granted him by the constitution or by law.
Article 9.
No one shall be subjected to arbitrary arrest, detention or exile.
Article 11.
(1) Everyone charged with a penal offence has the right to be presumed innocent until proved guilty according to law in a public trial at which he has had all the guarantees necessary for his defence. (2) No one shall be held guilty of any penal offence on account of any act or omission which did not constitute a penal offence, under national or international law, at the time when it was committed. Nor shall a heavier penalty be imposed than the one that was applicable at the time the penal offence was committed.
Couple other human rights USA does not follow:
Article 23.
(4) Everyone has the right to form and to join trade unions for the protection of his interests.
Article 24.
Everyone has the right to rest and leisure, including reasonable limitation of working hours and periodic holidays with pay.
