Controversial Sydney lawyer Sevag Chalabian, a representative for disgraced former Labor powerbroker Eddie Obeid, has been sentenced to up to 12 years prison for laundering $24 million in blackmail money in relation to the Plutus tax fraud.

Chalabian, 52, was sentenced on June 23 last year with a non-parole period of 7½ years over charges he knowingly dealt with more than $1 million in proceeds of crime through his solicitor trust account.
