A court decision is due on Tuesday on whether a UK arrest warrant against WikiLeaks founder Julian Assange is still valid.
He has been living inside the Ecuadorian Embassy in London for over six years following a sex assualt-related case brought by the Swedish prosecutors.
Those investigations have now been dropped, so Mr Assange maintains the arrest warrant is no longer valid.
His lawyers made an application at Westminster Magistrates' Court last month for the UK warrant to be withdrawn, saying it had "lost its purpose and its function".
Senior district judge Emma Arbuthnot is due to give her ruling on Tuesday, although either side can appeal against the decision.
Mr Assange believes he will be extradited to the United States if he leaves the embassy, for questioning about the activities of WikiLeaks.
His lawyers point out that the UK authorities refuse to confirm or deny whether a US extradition warrant has been received.
