A right outsider (5)

I believe the answer is:

alien

'outsider' is the definition.
(I've seen this in another clue)

'a right' is the wordplay.
'right' becomes 'lien' (legal right).
'a'+'lien'='ALIEN'

(Other definitions for alien that I've seen before include "repugnant" , "Martian, say" , "Someone from outer space?" , "Creature from another planet" , "Foreigner, outsider" .)

I've seen this clue in The Guardian and The Globe and Mail.
