تحول القواعد الدولية الاتفاقية إلى عرفية

الملخص EN

International custom is one of the oldest sources of public international law, and it is credited with forming this law.

However, it differs from international conventions as they are basic sources in that the latter is broader, clearer and more specific, while international custom is characterized by its ambiguity and breadth of comprehensiveness.

Therefore, countries sought to codify the rules of international custom in written documents in the form of multilateral or legal international treaties.

You find the broad scope of the obligation of these treaties in contravention of the principle of relativity of the effect of treaties.

If it is possible to transform customary rules into convention rules, the opposite is also true.

Convention rules can be transformed into customary rules by the abundance of text in the treaty documents and their frequent follow-up.

You will find that the convention rule turns over time into a customary rule that states are bound by, whether they are parties to the treaty or not.

This is certainly after the availability of the basic conditions that the international custom necessitates in its formation, which are the material pillar represented by the repeated behavior in adopting the agreement text, and the moral pillar represented by the mandatory belief towards this text.
