A decision on whether Megaupload employees should be extradited to the US on copyright and fraud charges has been delayed until 2013.
A New Zealand judge has postponed next month's hearing to allow more time to resolve legal arguments.
It follows earlier rulings regarding the rights of the accused and the legality of a raid on the file-sharing site creator Kim Dotcom's mansion.
The US is set to appeal against both decisions.
The case has been rescheduled provisionally for 25 March.
Mr Dotcom has been accused of copyright theft, money laundering and racketeering fraud and faces a jail sentence of up to 20 years if convicted in the US.
Prosecutors allege that pirated movies and other content shared through his site cost copyright holders more than $500m (Â£322m) in lost earnings, making it one of the biggest cases of its kind.
They claim Megaupload's staff paid users "whom they specifically knew uploaded infringing content", potentially encouraging the practice.
The US Department of Justice alleges the firm made about $175m from advertising and membership fees as a result of its activities.
Mr Dotcom's lawyers deny the charges saying the site simply offered an online storage service and that the majority of its traffic was "legitimate".
