The appellant, a Nigerian national residing in Zimbabwe, was arrested by immigration officials on 6 February 2012 under s 8(1) of the Immigration Act [Cap 4:02] on suspicion of being in Zimbabwe unlawfully. He filed an urgent chamber application in the High Court seeking immediate release from detention, arguing he was in Zimbabwe lawfully on the basis of an investor permit issued on 8 May 2007. The first respondent opposed the application, showing that: (1) the investor permit had expired in 2008 and was not renewed until 14 February 2012 (after arrest); (2) a provisional restriction notice allowing him to stay had expired on 20 January 2012; and (3) the appellant had been deported from Zimbabwe in June 2005, making him a prohibited immigrant. The first respondent filed a supplementary affidavit with Immigration Deportation Records confirming the 2005 deportation. The appellant denied having been deported and challenged the admission of the supplementary affidavit. The High Court admitted the supplementary affidavit, found the arrest lawful, and dismissed the application with costs.
