JUS COGENS
AND THE QUESTION OF CRITERIA FOR ITS DETERMINATION
JUS COGENS
AND THE QUESTION
OF CRITERIA FOR ITS DETERMINATION
Čestmír Čepelka
Abstract:
The focus of this contribution is on identification of peremptory norms
in general international law. Non-derogation by treaty is not the sole criterion for
determination of rules
juris cogentis.
There are also other non-derogable rules of
general international law (freedom of the high seas). The most important rules
juris
cogentis
are the prohibition of force and of genocide. Crimes against humanity are
wholly stabilized in customary law; its written form is still about to be finished,
including the activity of the UN International Law Commission. All general
peremptory norms of international humanitarian law (law of armed conflicts)
were developed from relevant treaties. The least stabilized is the principle of self-
determination of nations. There are long-standing general international rules which
also have non-derogable status – their derogation is actually in fact or logically
impossible (freedom of the high seas).
Resumé:
Obsahem tohoto příspěvku je problém určování kogentních norem obecné-
ho mezinárodního práva. Nederogovatelnost není jediným kritériem jejich určování,
ježto taková jsou i jiná pravidla obecného mezinárodního práva, která nejsou norma-
mi
juris cogentis
(svoboda moří). Nejdůležitější kogentní pravidla: zákaz uchylovat se
k síle a zákaz genocidia. Zločin proti lidskosti je už obyčejově stabilizován, jeho písem-
né vyjádření se teprve dotváří, včetně zájmu Komise pro MP. Všechna kogentní pra-
vidla mezinárodního humanitárního práva (práva ozbrojených konfliktů) se vyvinula
z příslušných smluv. Nejméně ustálena je zásada sebeurčení národů. Dávná jsou pra-
vidla obecného mezinárodního práva, jež jsou věcně nebo logicky nederogovatelná.
Key Words:
Peremptory norms of general international law; prohibition of force;
genocide; crime against humanity; international humanitarian law; principle of
self-determination; other rules of general international law with non-derogable
status (derogation in fact or logically impossible).
