Sorry to be a pain and apologies for if I'm being dense, but just so I understand fully, if in the future there was another dispute, would either one of the branches be able to call for IA independently or will it always automatically be under the Unite name and therefore involve both sections?
No problems at all - either branch can take independent action dependent upon the will or motivation of their memberships - so if CC89 voted for strike action at some time in the future and BASSA voted against - CC89 could still take that action (following all procedures etc)
