Sorry to put a dampner on your party but the high court judgment was nothing to do with the alleged planning infringements at coventry airport, or whether planning permission will be granted.
The high court ruling was that it was inappropriate for the action to have been taken in the high court.
Warwick District Council enforcement orders requiring the cessation of activities in the temporary terminal still stand and will come into force at the start of June. My understanding is that the airport will appeal against those notices, and that will then force a Public Inquiry later in the year.
It seems Coventry airport have won themselves a stay of execution
