General information, not legal advice.
Supreme Court of WA

Original judgment source is linked above.
(a) the content of all documents relate to the management of the business of the Environmental Defender's Office, including confidential human resource matters. The disclosure of this information would reveal business or professional affairs of the Environmental Defender's Office; and
(b) if the information was disclosed, this would be expected to prejudice the future supply of the business and professional affairs of charitable or nonforprofit organisations to University staff, a significant number of whom regularly volunteer their time in Board or community roles.
(a) On 30 January 2016, the principal legal officer and acting investigations officer met with the respondent to discuss the complaint. At this meeting, the acting investigations officer informed the respondent that it was the Commissioner's opinion at that time that:
(i) the documents in dispute were documents of an agency for the purposes of the FOI Act;
(ii) it was unlikely that a blanket claim of a cl 4(3) of sch 1 exemption (disclosure of business, professional, commercial or financial affairs of a person) on all the documents in dispute would be accepted by the Commissioner; and
(iii) each document must be considered individually as to whether it is exempt from release taking into account the provisions of the FOI Act.
(b) The respondent informed the Commissioner's officers that reviewing all of the documents in dispute individually (which consisted of a large amount of documents involving a third party organisation) would be difficult and time consuming.
(c) It was agreed that the respondent would review the disputed documents and liaise with the appellant to try to identify the documents that could be removed from the scope of the appellant's access to reduce the respondent's work involved in dealing with the application. Once the scope had been reduced the respondent could then consider whether any of the remaining documents were exempt.
(d) The acting investigations officer contacted the appellant and advised him of the outcomes in (a) to (c) and informed him that the respondent would contact him directly.
(e) On 14 and 15 February 2017, the respondent provided the appellant with a revised document schedule and a schedule of screenshots. The document schedule identified 192 documents in dispute that the respondent proposed to remove from the scope of the application. The respondent asked the appellant to confirm that he was willing to remove from the scope the documents it had identified. It also asked the appellant to consider any additional ways in which the scope of the access application could be further reduced.
(f) The categories of documents suggested by the respondent for removal from scope were:
(i) C1 documents or emails already provided to the appellant;
(iii) C3 documents involving logistical arrangements;
(v) C5 Environmental Defender's Office administration activities;
(vi) C6 - Environmental Defender's Office human resources and payroll arrangements; and
(vii) C7 correspondence between Environmental Defender's Office management committee and Slater and Gordon.
(g) After further discussions between the appellant, the respondent and the acting investigations officer, on and between 16 February 2017 and 13 March 2017, the total number of documents remaining that came within the scope of the appellant's application, after agreement was reached to reduce the number of documents, was 299.
(h) The respondent considered that dealing with the remaining 299 documents in dispute would still divert a substantial and unreasonable portion of the respondent's resources away from its other operations and therefore it sought to deal with the appellant's access application pursuant to s 20 of the FOI Act.
Section 20 is designed to ensure that the operations of government agencies are not unduly impeded by agencies having to deal with unreasonably voluminous access applications. It is one of a number of provisions aimed at striking a balance between on the one hand, the public interest in open and accountable government, and on the other hand the public interest in the ongoing effective operations of agencies.
As the agency has refused to deal with your [the applicant's] access application pursuant to section 20 of the FOI Act, when considering a complaint about an agency's refusal to deal with an access application in accordance with section 20, I must decide whether the agency:
(1) took reasonable steps to help you to change an application to reduce the amount of work needed to deal with it; and
(2) was justified in deciding that the work involved in dealing with your application in its present form would divert a substantial and unreasonable portion of the agency's resources away from its other operations.
(a) the respondent had taken reasonable steps to help the appellant to change the access application to reduce the amount of work needed to deal with it; and
(b) the respondent's decision to refuse to deal with the appellant's application pursuant to s 20 of the FOI Act was justified.
(1) The Commissioner's preliminary determination is misconceived because it fundamentally mischaracterises the entire context of this external review proceeding and the parties' access dispute.
(2) In his preliminary determination, the Commissioner misconceives and fails to properly exercise his powers and functions under Part 4 of the FOI Act.
(3) To the extent the Commissioner purports to permit the agency to adopt a preliminary refusal to deal under s 20 in the context of a Part 4 external review, again the Commissioner has misconceived Parts 2 and 4 of the Act and the limits on agency decisionmaking authority once external review has commenced.
(4) Even if the agency could make a s 20 refusal to deal determination in the context of a Part 4 external review, the Commissioner errs as a matter of law in considering that the agency has discharged its onus of proof to satisfy the conditions of either ss 20(1) or 20(2), both of which are required to justify a refusal to deal.
(5) The Commissioner appears to have violated principles of natural justice in proceeding to resolve this proceeding as he proposes to do in his 14 June 2017 preliminary determination.
(6) Rather than proceeding on the course outlined in the Preliminary Determination, the Commissioner should adopt the complainant's proposal for reducing the scope of his access application in order to facilitate the informal resolution of this proceeding.
(a) by an offer to reduce the scope of his request to 175 documents, as specified in a table in [130] of the submissions; and
(i) issue a final determination regarding whether access to documents nominated in accordance with the table in [130] should be disclosed in whole, or redacted in part, or withheld, within 30 days; and
(ii) direct the respondent to retain the remainder of the documents identified in the two schedules attached to its 26 August 2016 decision, and ensure that they are not destroyed or deleted.
(a) the Commissioner would not issue a final determination about access to the documents; and
(b) there would be the usual right of review following the respondent dealing with the application, if it accepted the appellant's proposal.
(a) informed that the Commissioner had considered all of the submissions made by the appellant in response to the Commissioner's preliminary view;
(b) asked whether it was able to deal with the matter on the basis of the reduced number of the 175 documents identified by the appellant in his further submissions; and
(c) informed that if it agreed to deal with the matter (on this basis) the Commissioner would close his file on the basis that the issue (that the agency had refused to deal with the application on grounds of s 20 of the FOI Act) had been resolved.
I refer to previous correspondence in relation to this matter and in particular the email sent to you on 1 September 2017 by my Legal Officer.
I am pleased to advise you that the University of Western Australia (the agency) has agreed to deal with the reduced scope proposed in your letter to me of 29 June 2017.
As advised in my Legal Officer's email to you of 1 September 2017, the agency will now deal with the matter and provide you with a notice of decision in relation to those documents listed in your revised scope. The usual right to review applies if you are not satisfied with the access you are given to the documents, after the agency has dealt with the matter.
As the current matter before me relates to the agency's refusal to deal with your application, I now consider the matter has been resolved by conciliation. I will write to parties to formally notify them that my file has been closed, on Friday 15 September 2017.
(a) mischaracterising and impermissibly recasting the complaint and decision made by the respondent as being a refusal to provide access under s 20 of the FOI Act, rather than a refusal of access on the merits of the access application under s 31 and s 30 of the FOI Act (grounds 1, 2, 4, 5, 10);
(b) misconstruing the appellant's proposal to reduce the scope of documents as an effort to reach conciliation with the respondent (ground 5);
(c) incorrectly applying s 76(2) of the FOI Act, identifying the wrong issue, asking the wrong question and failing to consider the relevant factors and questions put in the appellant's complaints (grounds 3 and 6);
(d) failing to consider the respondent's access decision, which resulted in the decision to close the file being manifestly unreasonable as it was not based on a rational consideration of the evidence and did not logically flow from the facts before the Commissioner (ground 9); and
(e) failing to afford the appellant procedural fairness by making a decision to close the file in disregard of the appellant's complaint and submissions objecting to the Commissioner's 14 June 2017 preliminary 'determination'. In particular, the Commissioner demonstrated prejudgment, or a closed mind to the appellant's complaint and submission, and failed to make findings on a substantial, clearly articulated argument set forth in the appellant's 29 June 2017 submissions (grounds 7 and 8).
The power of the Commissioner to deal with an access complaint
(1) A complaint may be made against an agency's decision
(a) to give access to a document; or
(b) to give access to an edited copy of a document; or
(c) to refuse to deal with an access application; or
(d) to refuse access to a document; or
(e) to defer the giving of access to a document; or
(f) to give access to a document in the manner referred to in section 28 or withhold access under that section; or
(g) to impose a charge or require the payment of a deposit.
(a) The Commissioner may, at any time after receiving a complaint, decide not to deal with the complaint, or to stop dealing with the complaint, because it does not relate to a matter the Commissioner has power to deal with or it is frivolous, vexatious, misconceived or lacking in substance.[5]
(b) The Commissioner's power to conduct proceedings to deal with the complaint is broad. The Commissioner may:[6]
(i) obtain information from such persons and sources and make such investigations and inquiries, as the Commissioner thinks fit. The proceedings are to be conducted with little formality and technicality;
(ii) determine the procedure for investigating and dealing with complaints and give any necessary directions as to the conduct of the proceedings;
(iii) deal with the complaint without holding formal proceedings or hearings;
(iv) direct that all submissions be in writing; and
(v) require parties to attend compulsory conferences.
(c) The Commissioner may, at any stage, suspend inquiries, investigations or other proceedings so that efforts can be made to resolve the complaint by conciliation or negotiation between the parties. In order to facilitate the resolution of the complaint by negotiation or conciliation the Commissioner may give such directions and do such other things as the Commissioner thinks fit.[7]
(d) In dealing with the complaint, the Commissioner has (in addition to any other power) power to review any decision that has been made by the agency in respect of the access application, and decide any matter in relation to the access application that could, under the FOI Act, have been decided by the agency.[8]
(a) deciding not to deal with the complaint or to stop dealing with the complaint on the grounds set out in s 67(1); or
(b) reviewing any decision that has been made by the agency in respect of the access application pursuant to s 76(1).
(a) confirming the agency's decision to which the complaint relates; or
(b) varying the agency's decision to which the complaint relates; or
(c) setting aside the agency's decision to which the complaint relates and making a decision in substitution for that decision.
An appeal to the court - in the nature of judicial review
Section 85 of the FOI Act creates a right of appeal to this court 'on any question of law arising out of any decision of the Commissioner on a complaint relating to an access application'. The FOI Act aptly uses the description 'review proceedings' to describe the proceedings brought under s 85: see s 88 FOI Act. In the context of a similar provision concerning appeals from decisions made under s 50(4) of the Freedom of Information Act 1982 (Vic), French CJ, Gummow and Bell JJ explained in Osland v Secretary to the Department of Justice [2010] HCA 24; (2010) 241 CLR 320, 331 - 332 [18] (Osland [2010]) that '[d]espite the description of proceedings under the section as an "appeal", it confers original not appellate jurisdiction; the proceedings are "in the nature of judicial review"'. See also Roy Morgan Research Centre Pty Ltd v Commissioner of State Revenue [2001] HCA 49; (2001) 207 CLR 72, 79 [15] (Gaudron, Gummow, Hayne & Callinan JJ).
Does the expression of a preliminary view of the Commissioner constitute a 'decision' within the meaning of the FOI Act and did the expression of a preliminary view constitute pre-judgment?
Judges often form tentative or preliminary opinions, and counsel are usually assisted by hearing those opinions and being given an opportunity to deal with them: Johnson v Johnson [2000] HCA 48; (2000) 201 CLR 488, 493.
The rule against bias is directed to prejudgment incapable of being altered, rather than predisposition capable of being swayed by evidence or argument: Minister for Immigration and Multicultural Affairs v Jia Legeng [2001] HCA 17; (2001) 205 CLR 507, 531 532 [71] [72] (Gleeson CJ & Gummow J).
Did the Commissioner make a 'decision' within the meaning of s 85(1) of the FOI Act on 15 September 2017?
(a) the appellant had not agreed that the respondent would review whether access could be given to a reduced number of documents; and
(b) all that the respondent had agreed to do at that time was to review the reduced number of documents referred to in the appellant's further submissions and provide the appellant with a notice of decision in relation to each of those documents.
85. What may be appealed etc.
(1) An appeal lies to the Supreme Court on any question of law arising out of any decision of the Commissioner on a complaint relating to an access application.
(2) An appeal lies to the Supreme Court from a decision
(a) of the Commissioner refusing or failing to make a decision of the kind mentioned in section 77(3); and
(b) by the Premier confirming an exemption certificate pursuant to section 77(4).
(3) There is no appeal under subsection (1) in relation to a decision of the Commissioner as to
(a) the deferral of the giving of access to a document;
(b) the charges to be imposed for dealing with the access application;
(c) the payment of a deposit under section 18.
(4) An appeal lies to the Supreme Court on any question of law arising out of a decision of the Commissioner on a complaint relating to an application for amendment of personal information if the effect of the decision is that information is not to be amended in accordance with the application.
(5) There is no appeal under subsection (4) in relation to a decision of the Commissioner as to whether or not to deal with a complaint or in relation to any other decision of the Commissioner not mentioned in subsection (4).
The word 'decision' is a word of indeterminate meaning. In some contexts, it can refer to the mental process of making up one's mind. In the context of judicial or administrative proceedings, the word will ordinarily refer to an announced or published ruling or adjudication. In such a context, the word 'decision' may be apt to include the determination of any question of substance or procedure, including, for example, rulings on procedural questions such as whether particular evidence should be received, or the meaning of the word may be limited to a determination effectively resolving an actual substantive issue. When the word 'decision' has the last mentioned limited meaning, it can refer to any such determination whether final or intermediate (see, for example, Registrar of Workers' Compensation Commission (NSW) v FAI Insurances Ltd (12)) or be limited to referring only to a determination which effectively disposes of the matter in hand (see, for example, Winter v Winter (13) and Penniel v Driffill (14)).
In my opinion, the Commissioner's requirement that the documents in question be produced to her was not a decision on a complaint from which an appeal lies under s 85 of the FOI Act. The decision was one preliminary to any decision on a complaint and was designed to put the Commissioner in a position where she could make a decision on a complaint.
The question whether an appeal lies is one of construction of the statute and is to be determined having regard to the text, scope and purpose of the Act: see Australian Broadcasting Tribunal v Bond [1990] HCA 33; (1990) 170 CLR 321; Director-General of Social Services v Chaney [1980] FCA 87; (1980) 47 FLR 80; Ralph M Lee (WA) Pty Ltd v Fort (unreported, Supreme Court, WA, Anderson J, Library No 8719, 22 February 1991).
Having regard to the provision of ss 63, 70, 76, 77(3), 78 and 85 of the FOI Act, it is clear that the extent of appeals permitted under the Act is restricted. In my opinion, those provisions do not indicate that an appeal will lie to this court in relation to intermediate decisions which are not decisions determining the rights of the parties to a complaint before the Commissioner.
Does an error of law arise in the decision made by the Commissioner on 15 September 2017?
An appeal 'on a question of law' is narrower than an appeal that merely 'involves a question of law'. Where an appeal lies 'on a question of law' the subject matter of the appeal is the question or questions of law. If a question raised by a litigant, properly analysed, is not a question of law, linguistic gymnastics in the formulation of the grounds of appeal cannot convert it into a question of law. A question of mixed law and fact is not a question of law within s 105(2). See, in the context of s 44(1) of the Administrative Appeals Tribunal Act 1975 (Cth), the observations in TNT Skypak International (Aust) Pty Ltd v Federal Commissioner of Taxation [1988] FCA 119; (1988) 19 ATR 1067 at 1069 1070; Birdseye v Australian Securities and Investments Commission [2003] FCAFC 232; (2003) 38 AAR 55 at 58 60 [10] [18]; Comcare v Etheridge [2006] FCAFC 27; (2006) 149 FCR 522 at 527 [13] [17]. Section 44(1) of the Administrative Appeals Tribunal Act provides that an appeal from a decision of the Administrative Appeals Tribunal may only be made 'on a question of law'. That provision is not materially different from the provisions of s 105(1) and (2) of the Western Australian Act.
A ground of appeal which asserts that a decision is against the evidence and the weight of the evidence does not raise a question of law. See Collins v Minister for Immigration and Ethnic Affairs [1981] FCA 147; (1981) 58 FLR 407, where Fox, Deane and Morling JJ said, at (410):
' ... the concepts of a decision being against the evidence and of being against the weight of the evidence belong to appeals from courts of law and have particular application to jury verdicts. Even in that context, they do not involve questions of law. They certainly have no place when the appeal, or review, is of proceedings of an administrative tribunal which is not bound by the rules of evidence and which, subject to the obligation to observe the requirements of natural justice, can inform itself as it chooses ... An appellant who attacks a conclusion of the [Administrative Appeals Tribunal] because of deficiency of proof said to amount to error of law must show, if he is to succeed, that there was no material before the Tribunal upon which the conclusion could properly be based.'
Also see Australian Broadcasting Tribunal v Bond [1990] HCA 33; (1990) 170 CLR 321 at 355 356 per Mason CJ (with whom Brennan J agreed); Comcare Australia v Lees [1997] FCA 1415; (1997) 151 ALR 647 at 652 653; Townsend v Minister for Immigration and Multicultural Affairs [2001] FCA 492 at [4] [7]; Hill v Repatriation Commission [2005] FCAFC 23; (2005) 40 AAR 500 at [92] [93].
A tribunal does not commit an error of law merely because it finds facts wrongly or upon a doubtful basis. See Waterford v Commonwealth [1987] HCA 25; (1987) 163 CLR 54 at 77; Minister for Immigration and Multicultural Affairs v Rajalingam [1999] FCA 719; (1999) 93 FCR 220 at 257 [146].
A ground of appeal that a tribunal has made a finding which is manifestly unreasonable, in the sense that no reasonable tribunal could have made that finding, alleges an error of law: see Minister for Aboriginal Affairs v PekoWallsend Ltd [1986] HCA 40; (1986) 162 CLR 24 at 39 40.
Section 38(2) of the Act provides for an appeal on a question of law 'arising out of an award'. The expression 'arising out of' may be the equivalent of the expression 'arising under,' or that of the wider expression 'connected with': see Samick Lines Co Ltd v Owners of Antonis P Lemos ('The Antonis P Lemos') [1985] AC 711 at 727.
In my opinion, despite views which have been expressed to the contrary, I consider that the wider meaning is intended. The limited meaning has been adopted in England: see Universal Petroleum Co Ltd v Handels und Transport GmbH [1987] 1 WLR 1178; [1987] 2 All ER 737; and in this State Minenco Pty Ltd v Abigroup Contractors (WA) (supra). In my opinion, with respect, the views expressed by Kirby P in his minority judgment (the point not being dealt with in the majority judgment) in Warley Pty Ltd v Adco Constructions Pty Ltd (unreported, Court of Appeal, NSW, 30 November 1988) are, nevertheless, compelling:
'It would seem curious, following the abolition of the restriction to errors of law "on the face of the award", effectively to reintroduce such a requirement, by the necessity to show that the impugned question of law arose out of the award in the limited sense of out of the award document.'
Taking into account, also, that errors of law do not amount to misconduct (see Forsayth (No 1)) injustice could well arise if there were to be no appeal on significant errors of law, connected with the award, but which do not appear from the face of the award.
The wider meaning has frequently been applied in Australia: see the authorities cited in M Jacobs, Commercial Arbitration Law and Practice, pars 34.360382.
A finding by the AAT on a matter of fact cannot be reviewed on appeal unless the finding is vitiated by an error of law. Section 44 of the AAT Act confers on a party to a proceeding before the AAT a right of appeal to the Federal Court of Australia 'from any decision of the Tribunal in that proceeding' but only 'on a question of law'. The error of law which an appellant must rely on to succeed must arise on the facts as the AAT has found them to be or it must vitiate the findings made or it must have led the AAT to omit to make a finding it was legally required to make.
The effect of the error of law in the decision of the Commissioner
When the Tribunal stands in the stead of the Commission [ASIC], it is no less favourably placed than the Commission. The Tribunal has all the powers and discretions that are vested in the original decisionmaker, provided that their exercise is only for the purpose of reviewing a decision that the Tribunal has power to review.
Of course, the Tribunal is not entitled to exercise a power conferred on a decisionmaker for some purpose unrelated to the decision under review. What this means in a given case must be determined by reference to the nature of the decision that the original decisionmaker was required to make.
Arguments relating to the jurisdiction of the Tribunal such as those presented in this matter are not new. In Re Control Investments Pty Ltd and Australian Broadcasting Tribunal (No 2) (1981) 3 ALD 88 at 92 President Davies J said of s 43(1) of the AAT Act:
'[T]he provision "For the purpose of reviewing a decision, the Tribunal may exercise all the powers and discretions that are conferred by any relevant enactment on the person who made the decision ..." is not concerned to confer upon the Tribunal authority to limit its function but rather to confer upon it an amplitude of powers so that the Tribunal may exercise, if it is convenient and useful to do so, not only the decision-making power upon which the decision-maker relied, but all relevant powers and discretions which were conferred by the enactment upon the decision-maker. The provision extends the authority of the Tribunal so that it may more adequately exercise its function of reviewing on the merits the subject decision.'
I certify that the preceding paragraph(s) comprise the reasons for decision of the Supreme Court of Western Australia.
