IF and it's a BIG IF.....the Club's press-release is correct, It would appear that the council knowingly and fraudulently falsified their application to "upgrade" the status of this airfield........therefore ,it seems logical that it has never legallyallowed operation of aircraft requiring the "runoff area" leased to the Club , assuming the club has not given a legally binding easement or waiver of their rights to fence this part of their leased property.
on the face of it, someone dropped a huge brick and is now attempting to use the powers of officialdom to rectify the situation.
Good luck to the small guys, I hope they ARE in the right and I hope they win their battle.
(no dog in the fight, never even seen Oban airfield. )
