Non-derogable definition
Non-derogable means inviolable, rights that no circumstances can justify suspending. And no national law can violate rights enshrined as non-derogable in international law binding on that nation: meaning, as EBCO argues, that as a signatory to the 1950 European Convention on Human Rights and the 1966 International Covenant on Civil and Political Rights, Ukraine’s martial law provision barring all males from 18 to 60 from leaving the country, in order to render them liable for military service, is illegal. Total mobilization, of course, is a practical and political impossibility; but while the state gives Itself the right to grant limited exemptions, even ‘permitting’ a few of those millions of men to travel, their human right to refuse to fight is denied.
