The suspended Nauru opposition MP, Roland Kun, has had his case to have his passport returned delayed until next month.
The opposition MP is seeking a legal review of the government's decision to seize his passport in June.
For the past three months the government has stopped Mr Kun from leaving the country by withholding his passport, after accusing him of involvement in an anti-government protest.
His case was due to be heard this week, but Mr Kun's supporters say it is now set down for October the 19th.
Meanwhile, Mr Kun says he is not able to comment on the Government's re-opening of an investigation into a fatal motor accident 24 years ago.
Mr Kun, who was 21 at the time, is alleged to have been drunk while driving a car which hit a motorcyclist who died.
A preliminary inquiry chose to take the case no further but the Justice Minister David Adeang says the Kun family used its political influence to stop the investigation.
