In recent publications on a possible extradition of Sisiku Tabe and his family to Cameroon, it was noted that Nigeria can not carry out this operation because she has not ratified the extradition conventions with Cameroon. Even if the Cameroonian authorities deny any involvement in this affair, their silence becomes deafening.
Here are the articles relating to the status of refugees (United Nations Human Rights)
Article 32. – Expulsion
1. The Contracting States shall expel a refugee lawfully from their territory only for reasons of national security or public order.
2. The expulsion of this refugee shall take place only in execution of a decision rendered in accordance with the procedure by law. The refugee shall, unless compelling reasons of national security prevent him, be admitted to furnish evidence tendering to exculpate him, to lodge an appeal and to be represented for that purpose before a competent authority or before one or more persons specially designated by the competent authority.
3. The Contracting States shall accord such a refugee a reasonable period of time to enable him to seek regular admission to another country. The Contracting States may, during this period, apply such internal measures as they deem appropriate.
Article 33. – Defense of expulsion and refoulement
1. None of the Contracting States shall in any way expel or return a refugee to the frontiers of the territories where his life or freedom would be endangered by reason of his race, religion, or nationality. his membership to a certain social group or his political opinions.
2. The benefit of this provision may not, however, be invoked by a refugee where there are serious reasons to consider a danger to the security of the country in which he finds himself or who has been the subject of a conviction for a particularly serious crime or offense, constitutes a threat to the community of that country.
