Apparently one Jolyon Maugham QC is. He has set up a crowdsourcing fund to pay for a legal challenge in, wait for it, the Irish Courts. The court action is against the Irish government and EU institutions for alleged breaches of Article 50. He claims that A50 is already triggered and that:
If it has already been triggered, he argues, the Commission is in breach of its duties by not starting Brexit negotiations.
However, if Article 50 has not yet been triggered, he argues that the EU Council and Irish state are in breach of their duties by excluding the UK from Council meetings.
It is hard to argue against the logic of the two statements, and before anyone starts down the road of it not going to happen then remember the Gina Miller case.
It would never get to court, but it did. Then it would be thrown out, it wasn't. The government would use the Royal prerogative anyway. It didn't, it appealed. The Supreme court would be on the government's side, we await its decision.....
