Background
Deng Kuom Kuot is a South Sudanese refugee who arrived in Australia at age 14 and held a Global Special Humanitarian visa. In 2021, his visa was mandatorily cancelled under section 501(3A) of the Migration Act 1958 (Cth) following criminal convictions. An Administrative Appeals Tribunal (First Tribunal) revoked that cancellation in July 2023, finding it was in the best interests of his four children in Australia to do so. The First Tribunal heard evidence from his former partner and the children themselves, documenting his active parental role until his imprisonment in January 2021 and his ongoing weekly telephone contact thereafter.
In August 2024, Kuot was convicted of assault occasioning actual bodily harm and remaining in a building with intent to commit an indictable offence, and was sentenced to two years imprisonment. His visa was cancelled again in September 2024 (mandatory cancellation). A delegate of the Minister refused to revoke this second cancellation. The Administrative Review Tribunal (Second Tribunal) affirmed that refusal on 8 August 2025, stating there was “minimal evidence” and “no reliable evidence” regarding the best interests of the children.
The Court’s Holding
Justice Shariff held that the Second Tribunal committed jurisdictional error by failing to consider relevant material—specifically, the First Tribunal’s detailed findings about Kuot’s relationship with his children and his ongoing contact with them. Although the Second Tribunal was aware the 2023 decision existed, it did not engage with or refer to those findings when assessing “best interests of minor children,” which is a primary consideration under Direction 110 paragraph 8.4 of the Migration Act.
The First Tribunal had made clear findings that Kuot visited his first three children every afternoon after work until his arrest in 2021, played a very active parental role, maintained weekly telephone contact while imprisoned, and spoke to the children daily while in immigration detention. The Second Tribunal’s bare conclusion that there was “no evidence” of regular contact after separation and no clear evidence of call frequency ignored these specific documented findings from the earlier proceeding. The failure to consider material that was central and prominent to a primary consideration constituted jurisdictional error.
The Court granted Kuot’s application for an extension of time to file his judicial review application, quashed the Second Tribunal’s decision, and remitted the matter for redetermination by the Second Tribunal according to law. Grounds 2 and 3 (irrationality and procedural fairness) were dismissed.
Key Takeaways
- Administrative decision-makers must consider relevant prior findings on material facts, particularly when assessing primary considerations such as best interests of children in migration cases.
- Silence or omission of reference to evidence in prior decisions does not relieve a tribunal of the duty to consider that evidence if it is material to a primary consideration under statutory directions.
- An unrepresented applicant’s reliance on prior proceedings and evidence creates a heightened risk that relevant material will be overlooked if not actively brought to the tribunal’s attention.
- Courts will extend time limits for judicial review applications where delay is explained by detention, language barriers, and disability affecting legal access.
Why It Matters
This decision reinforces a cornerstone principle of administrative law: decision-makers must base their decisions on all material available to them, and cannot ignore relevant findings or evidence bearing on mandatory considerations. In migration cases, the “best interests of the child” is explicitly designated a primary consideration, which means it must genuinely be weighed and not merely given cursory treatment.
The decision is particularly significant for unrepresented applicants and those appearing before administrative tribunals after prior proceedings. It establishes that prior tribunal decisions are part of the material before a subsequent tribunal and cannot be overlooked, even if the applicant does not explicitly re-tender evidence or re-call witnesses. The judgment also provides guidance on extension of time applications where applicants face detention, communication barriers, and accessibility challenges in accessing justice.
