A lawyer has defended the decision by former foreign affairs minister Marise Payne to impose sanctions on a Russian oligarch, over his alleged close ties to Vladimir Putin.
Billionaire Oleg Deripaska was banned from travelling to Australia in March last year following Russia's invasion of Ukraine.
The sanctions also stopped the industrialist from profiting from a shareholding in Rio Tinto-owned Queensland Alumina - which he was later legally frozen out of.
