High Court denies application, noting human rights treaties’ lack of substantive effect
High Court of Australia

A single justice of Australia’s High Court dismissed an application brought by an applicant alleging failures to comply with treaty provisions upon finding that the Australian Human Rights Commission Act gave no substantive effect to those treaties as Australian law. 

In the matter of an application by Jan Marek Kant for leave to issue or file [2025] HCASJ 40, the applicant’s fourth ex parte application sought leave to issue or file a proposed application for a constitutional or other writ against the following defendants, in connection with: 

  • Australia’s federal police commissioner 
  • the High Court’s principal registrar 
  • the United Nations’ high commissioner for human rights, the defendant in this proceeding 

Specifically, the applicant requested a writ or an injunction requiring the defendant to do everything necessary: 

  • to resolve the applicant's complaint in line with article 22 of the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment 
  • to resolve all complaints he already made to the Human Rights Committee pursuant to the Optional Protocol to the International Covenant on Civil and Political Rights 
  • alternatively, to resolve his complaint under the Optional Protocol 

The applicant claimed that he made six attempts to submit an individual communication to specific committees of the Office of the United Nations High Commissioner for Human Rights (OHCHR). He alleged that the defendant: 

  • failed to resolve the communications in compliance with the relevant treaty provisions 
  • did not acknowledge the applicant’s communications 
  • failed or refused to tackle the issues asserted in his communications 
  • failed or refused to sufficiently fulfill his duties under the Privacy Act 1988 (Cth) and treaties to which Australia was a state party 

The applicant argued that chapter III of the Constitution authorised the High Court to compel the performance of a duty imposed by any treaty to which Australia was a party. The applicant submitted an affidavit in support of his application. 

Last 23 September, Steward J ordered the non-issuance and non-filing of the application for a constitutional or other writ against the defendant, without a justice’s leave, under r 6.07.2 of the High Court Rules 2004 (Cth). 

The High Court registry raised the concern that the applicant previously tried to file a related application that pursued nearly identical relief and included substantially similar terms, with leave denied for being manifestly untenable and abusive of process. 

The applicant argued that his present application requested a different relief. Specifically, he alleged that the defendant refused or failed to deal with his complaints, rather than delayed dealing with his complaints. 

Leave denied

Justice Michelle Gordon of the High Court of Australia denied the applicant’s ex parte application, filed on 1 October 2025, for leave to issue or file an application seeking a constitutional or other writ, on its face and without seeing a need for an oral hearing. 

Gordon ruled that the applicant’s application for a constitutional or other writ against the defendant and the supporting affidavit: 

  • offered no rational legal argument to support the requested relief 
  • stated claims that were manifestly hopeless, abusive of process, and based on fundamental misunderstandings 
  • made misplaced claims based directly on breaches of human rights treaty provisions 

Gordon explained that the Australian Human Rights Commission Act 1986 (Cth) did not give the subject international human rights treaties and declarations any substantive effect as Australian law. Gordon added that the Privacy Act did not govern the defendant or the OHCHR.
