Victorian police have been ordered to explain why they have banned from Crown Casino alleged Melbourne mafia boss Antonio Madafferi, who is challenging the decision in court.
Mr Madafferi is fighting a decision made in 2014 by then chief commissioner Ken Lay to exclude him from Crown Casino based on concerns he was connected to organised crime.
The businessman wants the Victorian Supreme Court to overturn the ban.
Mr Madafferi also wants police to provide reasons for the exclusion order.
Justice Michael McDonald on Monday ordered Mr Madafferi to submit affidavits by next Monday and for police to reply by the following week.
The matter will return to court on August 30.
Mr Madafferi was not present in court during Monday's brief directions hearing.
He alleges the chief commissioner breached the rules of natural justice by not giving him a chance to be heard prior to the casino ban, according to an originating motion.
Mr Madafferi also says police failed to provide him with sufficient information about any allegations against him, or the evidence used to make their decision.
The owner of the La Porchetta pizza chain made national news headlines last week when it was revealed he and Victorian opposition leader Matthew Guy shared a lobster restaurant dinner, raising concerns about potential political donations.
