Zhang v Davidson (No 2)

In Zhang v Davidson, the Full Court of the Federal Court of Australia was called upon to review a decision made by a single judge regarding the application of the Migration Act 1958. The central issue in this case was whether the original decision to cancel the visa of the applicant, Mr Zhang, was lawful and whether the judge had correctly applied the law in reaching that decision. Mr Zhang, a Chinese national, had his visa cancelled on the basis of character grounds, specifically, that he represented a risk to Australia's national security.

The primary legal issues before the court were whether the primary decision-maker had correctly applied the Migration Act and the relevant judicial review principles, and if the decision was supported by sufficient evidence. The court needed to determine if the decision was legally sound, whether the primary decision-maker had considered all relevant factors, and if the evidence was adequate to justify the risk to national security.

The Full Court found that the primary judge had indeed applied the correct legal principles and had given sufficient consideration to the evidence presented. The court upheld the original decision to cancel Mr Zhang's visa, affirming that the primary decision-maker had acted within their jurisdiction. The evidence presented was deemed sufficient to support the conclusion that Mr Zhang posed a risk to Australia's national security. Therefore, the appeal was dismissed, and the visa cancellation was upheld.
