What happened
The appellant, a Tamil Hindu man from the northern province of Sri Lanka, arrived in Australia by boat in September 2012. He lodged an invalid application for a Class XA subclass 866 protection visa in October 2013 supported by a statutory declaration dated 23 September 2013. After the bar under s 46A(1) of the Migration Act 1958 (Cth) was lifted he applied for a Safe Haven Enterprise visa (SHEV) on 5 January 2016, supported by a further statutory declaration dated 24 December 2015. Both declarations contained claims that he and his family had been repeatedly questioned by Sri Lankan authorities, that he had been beaten, and that he had been sexually assaulted and tortured on two occasions by officers of the Criminal Investigation Department (CID). He claimed the authorities suspected him or his family of LTTE connections.
On 15 June 2016 the Minister's delegate interviewed the appellant. The transcript, set out at [14] of the joint reasons, shows the delegate expressly referred to differences between the 2013 declaration and later material, but told the appellant and his agent that "the discrepancies aren't major" and that she was "not putting a lot of weight on those discrepancies" because overall the evidence was consistent. The delegate also confirmed she accepted the sexual assaults had occurred, stating she had observed the appellant's "body language and his delivery" and was "satisfied that it occurred as claimed". Despite this acceptance the delegate refused the SHEV on 22 November 2016 on the basis that the appellant would not face a real chance of serious or significant harm on return.
The matter was referred to the Immigration Assessment Authority (IAA) under Pt 7AA. The appellant provided submissions on 3 December 2016 that recorded the delegate's acceptance of the sexual assaults but did not address inconsistencies, presumably because the delegate had downplayed them. The IAA listened to the recording of the delegate's interview ([20] of IAA reasons). At [21]-[32] the IAA identified a series of inconsistencies between the two statutory declarations, the entry and arrival interviews, and the SHEV interview. Several of these concerned the timing, duration and nature of the claimed CID detentions in 2012. At [27]-[28] the IAA highlighted differences in the appellant's account of the two sexual assault incidents. Cumulatively these led the IAA to find at [32] that the appellant "was not recalling a personal experience in relation to the events of April 2009 and beyond" and at [36] that it did not accept he was a victim of sexual assault. The IAA affirmed the delegate's decision on 20 July 2017.
The appellant sought judicial review in the Federal Circuit Court (FCCA). The FCCA dismissed the application on 26 July 2018, holding that the appellant and his agent had been on notice of the earlier declaration and the possibility of inconsistencies being considered by the IAA. On appeal to the Full Federal Court (Griffiths, Mortimer and Steward JJ) the sole ground pressed was that the IAA acted unreasonably by failing even to consider whether to exercise the discretion under s 473DC to obtain new information from the appellant. The Full Court allowed the appeal, set aside the FCCA orders and the IAA decision, and remitted the matter to the IAA for reconsideration according to law. The Minister was ordered to pay costs.
Why the court decided this way
The Full Court held that the IAA's failure to consider exercising the s 473DC discretion was legally unreasonable in two related respects: the treatment of the sexual assault claims and the treatment of the "relevant inconsistencies" the delegate had expressly downplayed.
Griffiths and Steward JJ at [46] reasoned that the IAA knew from the recording that the delegate's acceptance of the sexual assaults rested primarily on an assessment of the appellant's demeanour. The IAA itself had not seen or heard the appellant. The plurality in Fox v Percy [2003] HCA 22; 214 CLR 118 at [30]-[31] was cited to acknowledge that demeanour is not the only credibility tool, but here the IAA's adverse credibility finding at [35] rested on the cumulative effect of inconsistencies and implausibilities. Because the IAA lacked an independent evidentiary basis to reject the claims without assessing the appellant itself, it was unreasonable not to consider inviting him to an interview under s 473DC(3).
Separately, at [47] their Honours noted that the delegate had told the appellant the discrepancies "aren't major" and that she would not put "a lot of weight" on them. The appellant did not address them in post-interview submissions in reliance on that statement. The migration agent had also explained that some inconsistencies might stem from lack of access to prior statements. While the IAA was entitled to take a different view of the significance of the inconsistencies, the combination of the delegate's representations, the appellant's consequent silence, and the centrality of those inconsistencies to the IAA's rejection of the sexual assault claims meant the IAA was obliged to consider exercising s 473DC. There was no indication it turned its mind to the power. The failure was unreasonable or plainly unjust (Li at [76]).
Mortimer J, while agreeing in the result, placed greater emphasis on the qualitative difference between ordinary inconsistencies and those going to a claim of rape and sexual assault by state actors. At [115] she held a reasonable decision-maker who had listened to the recording would have reflected on whether an interview was needed to understand what had led the delegate to believe the appellant despite apparent variations. At [119]-[122] she stressed the importance of observing a person recounting traumatic sexual violence, the caution required before treating inconsistencies as probative of fabrication (citing AVQ15 v Minister for Immigration and Border Protection [2018] FCAFC 133; 361 ALR 227 at [23]-[28]), and the fact the delegate's acceptance had been communicated to the IAA through the appellant's submissions. Mortimer J confined legal unreasonableness to the sexual assault claims, viewing the IAA's treatment of other inconsistencies as consistent with DGZ16.
On materiality, the joint reasons at [52] found the error material because, had the IAA considered and exercised the power, it might have assessed the inconsistencies differently or been satisfied the assaults occurred. The IAA had attached "significance" to the inconsistencies; the Minister did not argue they were causally irrelevant. Mortimer J at [113]-[126] reached the same conclusion after analysing the centrality of the sexual assault narrative to the protection claims.
Before and after state of the law
Before DPI17 the law was clear that s 473DC is conditioned by legal reasonableness (M174 at [21]; CRY16 at [82]-[83]). DGZ16 had held that Pt 7AA contemplates the IAA evaluating the delegate's material for itself and does not generally require notification of adverse views or an opportunity to respond ([72]). CRY16 illustrated that where the IAA introduces a new issue not addressed by the delegate, failure to consider s 473DC may be unreasonable. DFW16 (relied on below but not on appeal) suggested unreasonableness where the IAA used material the delegate had not relied upon without giving the applicant a chance to comment. The FCCA had distinguished DFW16 on the basis that the delegate had referred to the 2013 declaration during interview.
DPI17 clarifies that DGZ16 is fact-specific and does not erect a bright-line rule. Even where the IAA is simply taking a different view of material before the delegate, particular circumstances—especially a delegate's positive demeanour-based credibility finding and express downplaying of inconsistencies—can render failure to consider s 473DC unreasonable. The decision reinforces that the "on the papers" default in s 473DB(1) admits of exceptions under s 473DC that must be considered reasonably. It also confirms that materiality is assessed as an ordinary question of fact by asking whether compliance could realistically have produced a different decision (SZMTA at [45]-[46]; Hossain at [30]-[31]).
After DPI17, decision-makers and practitioners understand that where a delegate has made representations about the weight to be given to inconsistencies or has relied on unobserved demeanour for serious claims such as sexual violence, the IAA must at least turn its mind to whether new information or an interview is required. The case has become a frequently cited touchstone for the boundaries of legal unreasonableness in fast-track reviews.
Key passages with plain-English translation
At [45] Griffiths and Steward JJ state: "the IAA's failure to consider whether or not to exercise its power under s 473DC in respect of either the issue of the sexual assaults or the relevant inconsistencies was legally unreasonable because, in the circumstances, the failure was unreasonable or plainly unjust". In plain English: ignoring the power was not just an oversight; given what the delegate had said and seen, any reasonable IAA would have at least thought about talking to the man again.
At [46(3)]: "if the IAA was minded to come to a different determination on the central question whether it was satisfied that the sexual assaults had occurred, unless there was available to the IAA a sufficient independent evidentiary basis to support such a determination without the IAA itself inviting the appellant to attend for an interview and conduct its own assessment of his demeanour, it was legally unreasonable for the IAA to fail to consider whether or not it should exercise its powers under s 473DC". Translation: you cannot reject a rape claim on paper alone if the delegate believed the victim because she saw him speak; you must at least consider hearing him yourself.
Mortimer J at [115]: "A reasonable decision-maker, having listened to the recording of the interview between the appellant and the delegate, having taken account of the delegate's remarks during the interview and having regard to her ultimate reasons, would have reflected on whether it was appropriate to interview the appellant, in order to see what it was about the appellant's account of the sexual assaults and rape that caused the delegate to believe him". Translation: after hearing the delegate say "I watched his body language and I'm satisfied", a sensible reviewer would ask whether they need to see the man for themselves before calling him a liar.
On materiality, the joint reasons at [52] note that "If the IAA had turned its mind to exercising the relevant power and then invited the appellant to provide 'new information' the IAA might have assessed the significance of the relevant inconsistencies differently". Translation: the error mattered because an interview or further explanation could have changed the whole outcome.
What fact patterns trigger this precedent
DPI17 is triggered where three elements coincide. First, the delegate has made an express representation during interview that inconsistencies are "not major" or will not attract significant weight, and the applicant relies on that representation by not addressing the point in submissions. Second, the delegate accepts a central element of the claim—particularly one turning on demeanour, body language or the manner of recounting traumatic events such as sexual assault—yet the IAA rejects that element by reference to the very inconsistencies the delegate downplayed. Third, the IAA gives no indication it considered exercising s 473DC to invite new information or an interview so that it can form its own view of credibility.
The precedent applies with particular force to claims of sexual violence by state actors where country information or medical evidence is inconclusive and demeanour is pivotal. It does not apply to ordinary differences in recollection that the delegate never addressed, nor where the IAA has an independent evidentiary basis (for example, clear country information or objective documents) that does not depend on credibility. Mere failure to consider s 473DC is never enough; the facts must show the failure lacks an evident and intelligible justification in the statutory context of limited review.
How later courts have treated it
Subsequent Full Court decisions have treated DPI17 as establishing a fact-sensitive outer limit on DGZ16. In EVS17 v Minister for Immigration and Border Protection [2019] FCAFC 20 the Full Court (Allsop CJ, Markovic and Steward JJ) cited DPI17 with approval when emphasising that materiality turns on whether the error "could have affected the outcome of the review". In ASB17 v Minister for Home Affairs [2019] FCAFC 38 the Court referred to DPI17 when discussing the evidentiary burden of proving the IAA did not consider the discretion.
Single judges have applied it where delegates made positive demeanour findings on sexual harm claims (see for example cases involving Tamil claimants with CID assault narratives). However, courts have distinguished DPI17 where the inconsistencies were not the subject of any delegate representation or where the IAA raised fresh country information rather than re-evaluating the same material. The decision has been cited in approximately two dozen Pt 7AA unreasonableness cases since 2019, usually as an example of when the "on the papers" default must give way. No court has suggested DPI17 overstates the obligation; rather, it is treated as an orthodox application of Li and M174 to the particular facts.
Still-open questions
Several questions remain unresolved. First, how far the delegate's "representation" must go before it triggers an obligation to consider s 473DC. DPI17 involved an express statement that discrepancies were not major; it is unclear whether a more ambiguous comment would suffice. Second, the precise role of demeanour in sexual assault claims post-DPI17: Mortimer J placed heavy weight on it, but the joint reasons were more measured. Whether an IAA must always consider an interview when reversing a demeanour-based acceptance is not settled.
Third, the interaction with s 473DD continues to generate difficulty. DPI17 did not require the IAA to admit new information; it required only that the IAA consider whether to invite it. How a court is to assess the realistic possibility of a different outcome when the IAA might ultimately have refused to consider the new information under s 473DD remains open. Finally, the extent to which Mortimer J's broader analysis of the link between legal unreasonableness and procedural fairness has been embraced is uncertain. The joint reasons did not adopt her Honour's full reasoning on that point, leaving room for argument in future cases about whether unreasonableness arguments should be analysed through a "natural justice lens" despite s 473DA.
Gotchas
Most practitioners still treat Pt 7AA as a pure "on the papers" regime and assume the IAA can always disagree with the delegate without further process. DPI17 shows that is dangerous when the delegate has looked the applicant in the eye, made reassuring statements about inconsistencies, and accepted serious harm on demeanour. The IAA member who simply listens to the recording and then writes "inconsistent therefore not credible" without recording any consideration of s 473DC is now at real risk of jurisdictional error. Another trap is assuming that because submissions to the IAA noted the delegate's acceptance of sexual assaults, that is enough; the Court looked behind the submissions to the delegate's actual representations during the interview. Finally, do not assume materiality requires the applicant to file an affidavit saying what he would have said if interviewed. The Court inferred materiality from the IAA's own reasons attaching "significance" to the inconsistencies. These nuances explain why seemingly routine IAA decisions are increasingly quashed on DPI17 grounds.
