Ava,
Whilst you are trying to justify the BASSA position why don't you also inform the rest of us as to how the, according to BASSA, 'nasty, vindictive company' allows you to live on the other side of the globe, maintain rosters that keep your non-dom status, enjoy a cost of living substantially less than that of the UK whilst paying non-domiclie tax which more than makes up for the loss of ST?
Not much sympathy here I'm afraid.
