Abstract

Born as an institute of common law, estoppel was introduced in International Law through the awards of British and American umpires in the 19th and 20th centuries. Later on picked up –implicitly or explicitly– by the PCIJ and the ICJ (Serbian Loans, Legal Status of Eastern Greenland, Fisheries, and Northern Sea Continental Shelf, amongst others), it has become a peremptory objection frequently asserted. However, the International Court does not seem to have been able to specify its constituents, thus leading to an inconsistent interpretation of both silence and the so-called detrimental reliance as well. The resultant uncertainty brings doubts as to the very existence of estoppel as a rule of International Law.
