The effect of the McKinnon Case

Authors Avatar

The McKinnon’s case was like a stepping on a landmine for both the media and the ministers. The media because they want the information, and the ministers’ because they use conclusive certificates to block the information.

Some history is needed first for McKinnon’s case. Michael McKinnon was the Freedom of information editor of the Australian at the time this case was heard. In 2002 he applied for information from the Australian tax office for documents relating to the taxation bracket creep and the First Home owners scheme.  During the end of 2003 and beginning of 2004 the Treasurer, Peter Costello MP, issued conclusive certificates under section 36(3) of the FOI act. The grounds were that the disclosure of the documents would be contrary to the public interest. 

Costello gave seven reasons as to why the conclusive certificates were issued. Then McKinnon took the matter to the Administrative Appeal Tribunal (AAT) for a review of Costello’s decision. The AAT found that the majority of the documents were exempt. Mckinnon appealed to the Federal Court in 2005 and then to the full bench of the High Court in 2006.

The question of law was whether the AAT when it carried out its review under section 58(5) of it FOI act, it had given proper consideration to all the relevant evidence and other material before it and to competing aspects of the public interest raised in the evidence or argument before it. 

The majority of the High court, Hayne J, Callinan and Heydon JJ agreed with the decision of the federal court and dismissed the appeal.

Hayne J said that the AAT’s task was to see whether the conclusion given in the certificate (that it would be against the public interest) can be supported by logical arguments. These arguments when taken together would support the conclusion given the in the certificate. The focus of the AAT is solely on the grounds of the conclusion and if they are reasonable grounds. He defined “reasonable” as not being non “irrational”, “absurd” or “ridiculous”. So if a conclusion was non absurd, it doesn’t make it automatically reasonable. 

The dissenting judges, Gleson CJ and Kirby J, said that logically, the view of the majority of the High Court appears to mean that, so long as there is anything to be said to support the view that disclosure would be contrary to the public interest, an applicant for review under s 58 (5) must fail period. They didn’t agree with that logic and said the appeal should be allowed. 

However  Haydon J, Gleason CJ and Kirby J, had a similar reasoning that all evidence and arguments both for and against disclosure of documents must be taken into account when the AAT undertakes its review under s 58(5).

Even though Mckinnon lost, two judges namely Heydon and Callinan JJ addressed the issue concerning the reasonableness of the reasons that Costello used to issue conclusive certificates.

They found that these are not reasonable ground against disclosure:

  • The fact that documents have continuing sensitivity, are controversial and affect a Minister’s portfolio.
  • The difficulty of putting financial data into context. A Minster should simply seek to explain the data and provide as accurate a context for it as possible.
  • The public may not be trusted to understand the technicalities of, and the jargon used in the released documents.
  • What might be disclosed could well be misrepresented, abbreviated or distorted, or at all not presented in a balanced way.

The following are reasonable grounds against disclosure:

  • A proper record of the process of decision-making and policy formulation can only be maintained if written advice is provided. Officers are less likely to provide candid, written advice if that advice is likely to be released in the future.
  • The documents were concerned with matters that were not settled and recommendations that were not adopted.
  • Documents that are prepared for possible responses to questions in Parliament should remain confidential because there exposure would threaten the Westminster system of government, id est responsible government. 

So from the legal side, McKinnon’s case was able to clarify the review powers of the AAT, and also what are reasonable grounds to issue a conclusive certificate because it is against the public interest.

But it also proved that conclusive certificates are very hard to overturn. So long as they are drafted correctly then the AAT won’t overturn them. Kirby J commented on this by giving a comparing the AAT to yes minister. He said, “the first any answer might be that this was a Sir Humphrey Clause: ‘This was put in to give the appearance of having this high level tribunal with judges and others to review but really, Minister, it gives them nothing to do.’”

However even if McKinnon did win, and the AAT did support the claim that the grounds were unreasonable, something stupid happens. Section 58A (1) of the FOI Act provides that the Minister can decide not to revoke a certificate by tabling a statement to parliament. So really the AAT can’t do much and only gives a recommendation to a minister.

All this begs the question, If a conclusive certificate is issued on the grounds of non disclosure because of non public interest concerns , what else can I do? Well Hayne J in the case suggested that McKinnon could have applied to the Federal Court under judicial review, since he got the information from the Treasurer under the Administrative Decision (Judicial Review) Act, instead of appealing to the AAT. He could have argued on the grounds of an error of law or an improper exercise of power. 

The High Court has considered the possibility of judicial review of ...
