SK (Sri Lanka) v Secretary of State for the Home Department [2008] EWCA Civ 495, [2008] All ER (D) 190 (May)
Rule 22 of the Immigration Tribunal (Procedure) Rules 2005 (SI 2005/230) provides only for a written determination. Although it is within the powers of the Asylum and Immigration Tribunal to pronounce an oral decision, it is the written determination which constitutes the formal determination.
