Here's a video of Theresa May explaining how she didn't get the timing of the arrest of Qatada wrong yesterday. It's a clever answer...
Because she gives herself two options. If the appeal is deemed to be outside the timeframe, then she can say The Home Office was right all along.
If the decision is made to hear the appeal she can argue that this has been done at the discretion of the court and no mistake was made.
It neutralises the possibility that she can be blamed for any mistake - which as @paulwaugh pointed out yesterday, seems a likely scenario.
Quite clever really.
But still not a safe pair of hands.
