Demean.
I do swear that I will truly and honestly demean myself in the practice of a barrister and solicitor of the Supreme Court of Western Australia according to the best of my knowledge and ability,
So help me God.
The oath I swore before the Full Bench of the Supreme Court on 22 December 1989 as part of the Admission Ceremony to become a legal practitioner.
They’ve since removed from the oath ‘demean myself’.
