The Fiji Law Society will question the deputy speaker over his alleged role in swearing in ministers in 2000 after the elected government had been overthrown.
The Daily Post says Ratu Rakuita Vakalalabure will appear before a disciplinary committee on October the 8th.
Ratu Rakuita says he is unaware of being charged for any disciplinary offence while the Law Society's secretary says it cannot comment on discioplinary cases.
The administration sworn in by the coup makers was sidelined when the military arrested some of those involved in the coup and appointed an interim government.
Under the Legal Practitioners Act, the Law Society has the power to suspend a member.
