text: # Minister for Immigration and Multicultural Affairs v Yusuf
  
  Minister for Immigration and Multicultural Affairs v Yusuf, also known as 'Yusuf', is a decision of the High Court of Australia.
  
  It is an notable case in Australian Administrative Law, particularly for its holdings regarding s430 of the Migration Act, and the meaning of jurisdictional error.
  
  As of September 2020, 'Yusuf' is the 16th most cited case of the High Court.
  
  ## Background
  
  The appeal concerned four appeal proceedings in which refugee visas had been denied by the Refugee Review Tribunal. Each appeal reached the High Court via the appeal process written in Part 8 of the Migration Act.
  
  Each appeal argued that insufficient reasons had been provided by the decision makers who had denied the plaintiffs visas, under the act. Section 430 of the act mandated that decision makers provide reasons for their decision. All four appeal proceedings were successful before the Full Federal Court.
  
  The Minister then obtained special leave at the High Court.
  
  ## Judgement
  
  The High Court held that the reasons provided by the tribunal in each case was sufficient to satisfy s430.
  
  Additional commentary was provided by the court as to the meaning of 'jurisdictional error'. Regarding Jurisdictional error, the court wrote:
  
     It is necessary, however, to understand what is meant by "jurisdictional error" under the general law and the consequences that follow from a decision‑maker making such an error. As was said in Craig v South Australia, if an administrative tribunal (like the Tribunal)
     "Jurisdictional error" can thus be seen to embrace a number of different kinds of error, the list of which, in the passage cited from Craig, is not exhaustive. Those different kinds of error may well overlap. The circumstances of a particular case may permit more than one characterisation of the error identified, for example, as the decision‑maker both asking the wrong question and ignoring relevant material. What is important, however, is that identifying a wrong issue, asking a wrong question, ignoring relevant material or relying on irrelevant material in a way that affects the exercise of power is to make an error of law. Further, doing so results in the decision‑maker exceeding the authority or powers given by the relevant statute. In other words, if an error of those types is made, the decision‑maker did not have authority to make the decision that was made; he or she did not have jurisdiction to make it. Nothing in the Act suggests that the Tribunal is given authority to authoritatively determine questions of law or to make a decision otherwise than in accordance with the law
