Pat Hickey's trial for alleged ticket touting will begin in Rio in November.
In a statement published by the trial judge Guilherme Schilling Duarte on the courts system in recent days, he says there is just cause to proceed with the criminal trial.
It comes almost a full year after the former OCI President left Brazil after being charged in connection with allegations of ticket touting at the Olympic Games.
The judge set a date of November 29th for the court in Rio.
Mr Hickey - who had initially been detained in Rio - was given permission to return to Ireland last Christmas on medical grounds upon payment of a bond worth more than €400,000.
Last week the Prosecutor said if Mr Hickey does not return for trial his bond will be retained locally.
Mr Hickey's legal team had suggested he may testify by video link, at the discretion of the judge.
In a published statement on the courts website, the Judge says both Pat Hickey and Kevin Mallon have responded to criminal accusations relating to the ticket touting controversy so far.
Defence teams for both men have claimed no crime has been committed by their clients.
Mr Hickey has previously insisted he is "totally innocent of all these charges".
The judge says the arguments of legal teams "will be resolved during the course of the instruction", and he said all the conditions necessary to ignite penal action are present.
