The Fiji Law Society president, Dorsami Naidu, says the interim regime is further purging the justice sector of people who don't toe the line.
Three magistrates and several public prosecutors have been sacked this week without the public being given an explanation.
The Fiji Independent Commission Against Corruption, or FICAC, has broadened its operations, charging a member of the International Commission of Jurists, Imrana Jalal, and her husband with operating a restaurant without a licence.
Ms Jalal denies the charges.
Mr Naidu says the regime seems tough on those opposing its agenda.
"It's in regards to the views the magistrates have on certain charges being laid by FICAC, which are not within their powers and the magistrates have told them so. That's one reason and certain other views they have on certain cases brought by FICAC. They are probably not toeing the line."
Dorsami Naidu says little is known about the sackings of the prosecutors.
