Before the primary judge
5 The primary judge provided a concise but thorough summary of the facts and circumstances as follows (at [2]-[11], footnotes omitted):
The applicant is a national of Sri Lanka, a Tamil, and a Christian. He arrived in Australia on 20 August 2012 as an unauthorised maritime arrival. The applicant was detained and underwent a "biodata" interview [on 20 August 2012], and, later, an "Irregular Maritime Arrival Interview" [on 16 January 2013]. On 31 January 2013 the applicant was granted a Temporary Humanitarian visa.
On 16 August 2013 the applicant, with assistance, lodged a form of application for a Protection (Class XA) visa (purported PC Application) with the Department of Immigration and Border protection (as the Department of Home Affairs was then known) (Department of Immigration). The applicant included in that application a statutory declaration in which he set out his claims for protection (2013 Statutory Declaration).
By letter dated 26 May 2014 the Department of Immigration informed the applicant's representative that the application the applicant lodged "is not currently a valid application"; and that it was invalid because of s.46(2A) or s.91K of the Act or both (as those provisions stood at the time the applicant purportedly applied for a protection visa). The letter further stated that the applicant was prevented from lodging a valid application unless the Minister agreed to lift the bar provided for by those provisions. The letter concluded:
When the Minister makes a decision, you will be notified and requested to lodge the Visa Application Charge (VAC) for your respective clients within a certain timeframe, when that payment has been correctly made it will render the application valid.
Even though the Department of Immigration treated the purported PC Application not to be a valid application for a visa, the Department of Immigration opened and maintained a file in relation to it. The file contains a copy of the purported PC Application, including the 2013 Statutory Declaration, a copy of the Department of Immigration's letter dated 26 May 2014, a notification from the applicant's representatives that they were no longer acting for the applicant, and a request for the payment of the costs of certain health services to the applicant.
By letter dated 17 August 2015 the Department of Immigration sent a letter to the applicant, the opening paragraph of which is as follows:
You have previously submitted a purported application for a subclass 866 Permanent Protection visa. However, as you have arrived in Australia unlawfully and you were affected by one or more application bars in the Migration Act, this application was invalid and cannot be processed any further. We have returned a copy of your original application form to you with this letter.
The letter then referred to changes in the law about the protection application process for certain illegal maritime arrivals, identifying the Migration and Maritime Powers Legislation Amendment (Resolving the Asylum Legacy Caseload) Act 2014 (Cth). After referring to the "Fast Track Assessment process", the letter referred to the applicant's having entered Australia as an unauthorised maritime arrival, and, therefore, to the applicant's being prevented by s.46A(1) of the Act from lodging a valid application for any visa while in Australia. The letter then stated that the Minister had exercised the power under s.46A(2) of the Act to allow the applicant to lodge a valid application for a Temporary Protection (subclass 785) visa (TPV) or a SHEV, and the applicant was invited to lodge an application for a TPV or a SHEV within 28 days.
The applicant applied for a SHEV on 17 September 2015. It was accompanied by a statutory declaration made by the applicant in which he stated his claims for protection (2015 Statutory Declaration). The 2015 Statutory Declaration is largely identical with the 2013 Statutory Declaration. The applicant made the following claims:
a) The applicant was born in Jaffna where he lived until 1996 when he and his family moved to Vanni. The applicant stayed there for two years when he moved to Mannar.
b) In 2006, while the applicant's mother, father, and brother were driving by motorbike, a "white van came and rounded them up". The applicant's father was beaten as a result of which he was badly injured, lost one eye, and stopped working.
c) While in Mannar the applicant's cousin was forced to join the Liberation Tigers of Tamil Eelam (LTTE). The cousin fought, he was injured, and taken prisoner by the Sri Lankan Army (SLA) who detained him until [date]. After his release the applicant's cousin stayed with the applicant. In the meantime the applicant's cousin's brother was taken by the SLA on suspicion of being a member of the LTTE.
d) While the applicant's cousin stayed at the applicant's house the Sri Lankan "intelligence authorities" came to the applicant's house regularly, and they questioned him accusing him of being in the LTTE and helping them. He was invited to attend an intelligence camp under the pretence of requesting him to carry out mechanical work, but when he arrived he was interrogated and tortured. They threatened to do to the applicant what they did to the applicant's cousin. The applicant was released but the applicant attended the camp on a further four occasions during which he was interrogated and, on one occasion, again tortured.
e) The applicant then realised it was not safe for him to stay in Sri Lanka. On the advice of his mother the applicant left Sri Lanka and came to Australia by boat.
The delegate did not accept the applicant's claims and, on 1 April 2016, rejected his application for a SHEV. Although the delegate accepted it was plausible that in 2008 the applicant might have been detained for a brief time for questioning about [an event] in [a place], the delegate did not accept the applicant had been repeatedly detained, tortured, and accused of being a LTTE supporter or potential bomb maker. Nor did the delegate accept that the applicant's cousin's brother had been detained. The delegate found the applicant had provided contradictory evidence regarding the instances he claimed to have been detained.
The delegate's decision was referred to the IAA on 4 April 2016. There is in evidence a copy of a document titled "Referrals to the Immigration Assessment Authority (IAA) and Disclosure Checklist" (Checklist). The Minister produced this document in answer to a notice to produce which called for the production of, among other things, "correspondence including emails relating to the constitution and provision of 'review material' by the secretary to the Authority pursuant to s 473CB Migration Act". Under the heading "File format", the Checklist states that the "applicant file is contained in a PDFP", which the Checklist notes stands for "PDF Portfolio". Under the heading "The PDFP contains the following material" there is a table divided into three columns. The first column, which is headed "Description", describes documents, the second, which is headed "Status", provides for the noting of "Yes", "No", or "N/A", and the third is titled "Non-disclosure considerations". Relevant to the proceeding before me is the document the Checklist describes as "Any referenced visa applications made by the applicant" to which the status of "N/A" is assigned.
The IAA accepted the applicant's cousin fought with the LTTE, that the cousin suffered serious injuries, later released from a rehabilitation camp, and, when released, came to live with the applicant's family who cared for him. The IAA also accepted that authorities visited the applicant at his home about two months after the applicant's cousin had been released, and again one week later. The IAA did not, however, accept that the applicant was questioned or tortured. The IAA particularly relied on the applicant's failing to mention having been tortured until he lodged his application for a SHEV in September 2015.
6 The Authority's reasons at [63], being the portion referred to in the last sentence of the primary judge's reasons reproduced above, was as follows, to which may be added [64]-[66]:
[63] I accept that victims of torture and trauma may find it difficult to recall or provide details of their experiences, however, the applicant did not even mention claims of questioning and torture until he lodged his SHEV application in September 2015. The applicant was provided with a Tamil interpreter at the biodata interview and the entry interview as well as at the SHEV interview [on 11 November 2015].
[64] I consider it implausible that given his claims of four or five questionings, including being tortured twice, the applicant did not mention these events either at the biodata interview (where he said there was "no guarantee for [his] life" and he "fears the Sri Lankan Army") and in the entry interview (where he mentioned the abduction of [a person] and the applicant's questioning, in 2008, regarding [an event]).
[65] I accept that the biodata interview form asks the applicant to set out his reasons for seeking protection in one sentence. If a request for brevity resulted in this omission, the applicant had another opportunity to mention these events at the entry interview which was conducted some five months later.
[66] Having listened to the recording of the entry interview, I am satisfied that the applicant was afforded ample opportunity to set out claims of torture and frequent questioning by the authorities. He was not hurried or asked to keep his answers brief and, at the end of the interview, the applicant was asked if there was anything else he wanted to say and he replied in the negative.
7 The primary judge considered that the application for judicial review gave rise to four questions, which his Honour listed as follows (at [18]):
(a) Did the Secretary consider whether the 2013 Statutory Declaration was relevant to the review?
(b) If (a) is answered in the negative, did the Secretary fail to comply with s.473CB of the Act?
(c) If (b) is answered in the positive, was the IAA's decision affected by jurisdictional error?
(d) If (a) is answered in the affirmative, was it reasonably open to the Secretary to consider the 2013 Statutory Declaration not to be relevant to the review?
8 In relation to the first two questions, the primary judge found that the Secretary (via an officer of the Department):
(1) did not consider the relevance of the 2013 statutory declaration (either by reason of the person who completed a checklist of materials to be referred to the Authority not turning his or her mind to whether a prior protection visa application had been made, so was not aware of the existence of the 2013 statutory declaration, or if he or she was aware of its existence, did not consider whether it was relevant); and
(2) did not consider it relevant to search for materials that showed that the appellant had previously made an application for a protection visa, including such an application that was not valid.
The primary judge concluded that this was not in breach of s 473CB of the Migration Act because the Secretary was entitled to proceed upon the basis that a protection visa applicant included in the application all of his claims for protection, and because the Minister is not to consider an application that is not valid pursuant to s 47(3).
9 The primary judge then considered the remaining two questions upon the basis that the Secretary had not complied with s 473CB, being a basis contrary to his Honour's conclusion summarised above that there was no breach of that provision.
10 As to the third question, his Honour found that the Authority's jurisdiction is not conditioned by strict compliance with s 473CB(1)(c) if the material in question could not have made a difference to the outcome of the Authority's review of the delegate's decision. His Honour found that in this case there was no material difference between the appellant not having made claims of questioning and torture until his 2015 statutory declaration, and not having made those claims until his 2013 statutory declaration, because the key fact relied upon by the Authority is that those claims were not made at the time of his biodata and arrival interviews.
11 In relation to the fourth question, the primary judge found that it would have been reasonably open to the Secretary to consider that the 2013 statutory declaration was not relevant under s 473CB(1)(c) because the information in it was reproduced in identical terms in the 2015 declaration that was given to the Authority. The primary judge also held that it would have been open to the Secretary to consider that the applicant's claims made in the 2015 Statutory Declaration represented his claims in their entirety and so, for that reason, the 2013 Statutory Declaration was irrelevant.
