This article seeks to highlight the fact that the principle of non-refoulement articulated in the 1951 Convention on the Status of Refugees has given responsibilities to States in ensuring the effective protection of refugees’ rights by averting their return or expulsion to countries where they will be persecuted. As seen in evolving international law policies, this principle is gradually gaining ground as a peremptory norm of International Law. This article also indicates that the application of this principle in International Law is supplemented by International Human Rights instruments. Cameroon has internationalized the 1951 Convention by enacting a law relating to the status of refuges in Cameroon. As such, this research holds that the exceptions to the principle of non-refoulement provided under Cameroonian law does not afford enough protection to refugees thus necessitating that the law should be reviewed.
