Theresa May put on the spot over Human Rights cat
Indeed in response to Ms May's speech the Judicial Office of Communications have taken the step of re-issuing a statement they made two years ago when the story first surfaced.
A spokesperson for the Judicial Office said: "This was a case in which the Home Office conceded that they had mistakenly failed to apply their own policy - applying at that time to that appellant - for dealing with unmarried partners of people settled in the UK.
"That was the basis for the decision to uphold the original tribunal decision - the cat had nothing to do with the decision."Such a speedy rebuttal of the Home Secretary's claim has already led to her being put pressed on the claim in her post-speech interviews.
"Of course the things that I said in my speech were checked," she told Radio 4's The World At One this afternoon.
However, she added: "If somebody is claiming something different then obviously I will look at that."
From Full Fact's point of view we wish the Home Secretary had been a bit more thorough checking the content of her speech before she made it.
But the upside is that, given the wide coverage given to Ms May's claim, that by referencing this story the Home Secretary may have made a significant contribution to taking it out of circulation once and for all.
