One thing that did become clear from the legal ruling is that Article 43 does not apply to the existing BA Scope clause in the UK. It's under that deal that the GSS secondee arrangement exists. BA would be a little daft to go and poke a stick in that hornets nest right now. GSS could kick the secondees out any time they like. Their problem is that BA then couldn't use GSS for their cargo without breaking the Scope agreement.
