See eg NABE v Minister for Immigration & Multicultural & Indigenous Affairs (No 2) [2004] FCAFC 263:
The Tribunal is required to deal with the case raised by the material or evidence before it – Chen v Minister for Immigration and Multicultural Affairs (2000) 106 FCR 157 at 180 [114] (Merkel J). There is authority for the proposition that the Tribunal is not to limit its determination to the ‘case’ articulated by an applicant if evidence and material which it accepts raise a case not articulated – Paramananthan v Minister for Immigration and Multicultural Affairs (1998) 94 FCR 28 at 63 (Merkel J); approved in Sellamuthu v Minister for Immigration and Multicultural Affairs (1999) 90 FCR 287 at 293 – 294 (Wilcox and Madgwick JJ). By way of example, if a claim of apprehended persecution is based upon membership of a particular social group the Tribunal may be required in its review function to consider a group definition open on the facts but not expressly advanced by the applicant – Minister for Immigration and Multicultural Affairs v Sarrazola (No 2) (2001) 107 FCR 184 at 196 per Merkel J, Heerey and Sundberg JJ agreeing. It has been suggested that the unarticulated claim must be raised ‘squarely’ on the material available to the Tribunal before it has a statutory duty to consider it – SDAQ v Minister for Immigration and Multicultural and Indigenous Affairs (2003) 199 ALR 265 at 273 [19] per Cooper J. The use of the adverb ‘squarely’ does not convey any precise standard but it indicates that a claim not expressly advanced will attract the review obligation of the Tribunal when it is apparent on the face of the material before the Tribunal.
