How about the following as a likely BA plan:
Court case in February, BA likely to win.
Fairly strong yes vote for a strike.
BA point out to BASSA that ballot is illegal, same reasons as before.
BA do not however go to court to prevent strike.
Strike starts some time in March, but not over easter.
BA immediately sack strikers, and anyone calling in sick.
Strike over almost before it starts.
Sacked CC take BA to tribunal for unfair dissmissal.
BA now challenge legality of strike, then contest the unfair dissmissal claims. BA may lose but the process could take years, and meanwhile, those sacked are still unemployed.
Anyone see any flaws with this plan? Best result for BASSA would be a no vote or BA to contest the ballot before the strike takes place. Neither of these is likely.
