The Nauru opposition MP Roland Kun has high hopes he'll be able to reunite with his family in New Zealand after a lawyer arrived at the weekend to help him fight his case.
Mr Kun has been forced to stay on Nauru after the government cancelled his passport.
He is waiting for his lawyer Georgie Coleman to be admitted to the Nauru bar under urgency so his case against the Nauru government can proceed.
Ms Coleman was granted a visa by the Nauruan government and is representing Mr Kun for free.
They are hoping the case will go ahead tomorrow if certain formalities are waived.
Mr Kun was pulled off a plane a month ago as he tried to leave Nauru and has since remained apart from his young family.
He's one of five opposition MPs in Nauru who have either had their passports cancelled or are facing criminal charges in the wake of protests against the government last month.
Two of the MPs were bailed last week after a month in custody.
There has been mounting international pressure on the Nauru government over its treatment of the MPs.
