A single precedent is not enough to establish a
customary rule, and that there must be a degree

must be based on a constant & uniform usage.

In the Asy lumcase, Victor Raul Haya de la Torre, the
leader of unsuccessful rebellion in Peru in 1948, obtained
asylum in the Colombian Embassy in Lima. Peru &
Colombia referred to the court (ICJ) the question whether
Colombia had the right to grant asylum & whether heshould be handed over to the Peruvian authorities or be
granted safe-conduct out of the country.
In other words, what prevented the formation of a
customary rule in the Asy lumcase was no t theabsence of repeti t ion , bu t the presence of major
inconsistenc ies in the pract ice.
