The Immigration Appellate Authority (IAA) was an independent judicial body in the United Kingdom constituted under the Immigration Act 1971, with jurisdiction to hear appeals from many immigration and asylum decisions. Administered by the Tribunals Service, it was superseded in 2005 by the Asylum and Immigration Tribunal, which itself was superseded in 2010 by the Asylum and Immigration Chamber of the First-tier Tribunal created by the Tribunals, Courts and Enforcement Act 2007.
