Unless there's some kind of constitutional impediment, a future Parliament can always change a statute. So the question you have to ask yourself is this: where we have received information on specific undertakings, whether it's census data, security data, or other types of data, do we then unilaterally change the law and breach the undertakings we made to those people when we first collected that information?
In the last Parliament, and even before that, there was a broad discussion about the release of census information for the purposes of genealogy. There was quite a groundswell of people wanting that type of information, and yet the prior government was rightfully concerned that the information had been acquired under certain circumstances. They didn't want to breach those undertakings. I believe that we ultimately arrived at some kind of compromise in terms of how many years we had to wait. I can't remember the details. But even so, by statute, we were breaching an undertaking that was made, whether it was 50 years ago or 100 years ago.
So that is a concern. We can always make the changes in the law, but let's look at the impact we're having, then, and at the undertakings we've made in the past.
