Just O`Leary testing the waters again.He will have taken extensive legal advice beforehand. This is a case going to be heard at a Liverpool County Court but not until April next year. Win or lose one side or the other will pursue it to the Supreme Court( maybe even the European Court) which will take years.At the present time though, his statement re the courts would not constitute contempt, nor will it, until all such legal avenues have been pursued.
By that time, the terms and conditions of Brexit will have been formulated and maybe even implemented. At that point, his lawyers will revisit such cases again in the light of circumstances then prevailing.
Or if you prefer just another O`Leary stalling tactic..
