"For I will look forward to the day when this Government declares that the world is flat, that the moon is made of green cheese, that I am Mickey Mouse"

I note that the formula used is that "that (the Act)is, in her view , compatible with the European Convention on Human Rights" rather than that the Act is in fact comnpatible with teh European Convention. In other words it is merely a statement about her opinion.

So it would presumably be perfectly in order to make a similar statement about the Earth being flat or the Moon being made of Green Cheese, or Shambles actually being Mickey Mouse, so long as it was a truthful account of the state of mind of the Government representative making it.

However quite why the subjective opinion of a Government Minister about such matters should be seen as carrying any particular weight is a bit hard to see.
