There's actually no legal journalistic privilege. That is a convention, and I have no doubt she'll honour that convention.
But it is very hard to believe, reading what's written here, that this was not meant as very much a deliberate strategy that came from the very top. About the information that was leaked, Mr. Chan asserted at a previous meeting that it was purely negative—that is, it only said what wasn't in the bill—but it said so in a very thorough and exhaustive manner.
I'm reading from the article, that says it's “a bill that will exclude those who only experience mental suffering, such as people with psychiatric conditions”. It goes on to say this:
The bill also won’t allow for advance consent, a request to end one’s life in the future, for those suffering with debilitating conditions such as dementia. In addition, there will be no exceptions for “mature minors” who have not yet reached 18 but wish to end their own lives.
These prompted, in the very same story in which this was leaked, a response from Kay Carter's daughter, and that set the tone for all initial discussion of the legislation—which was that such condemnation as occurred, such criticism as occurred, was entirely on the bill not going far enough.
So this was a brilliant exercise, I think a brilliant and very successful exercise, in misdirection of the public debate on what is the most important piece of legislation in the 42nd Parliament. That could not have occurred because some low-level staffer leaked it out. This was very much part of a strategy. My guess is that it came directly out of the Prime Minister's Office. I do not blame the Minister of Justice, per se, for this, although she may or may not have known what was going on.
This deserves a proper investigation. Speaking to the reporter seems a reasonable place to start.
