The passport which stranded a Toronto woman in Kenya for months is now at the centre of a standoff between Ottawa and Suaad Hagi Mohamud's lawyer.

Mohamud was stuck in Nairobi for almost three months after authorities said her lips did not match her four-year-old passport photo.

Her lawyer, Raoul Boulakia, wants the government to immediately turn over to him Mohamud's passport and case file. He is taking his demands to Federal Court.

Boulakia says he wants to see the passport to determine whether consular officials were justified in calling Mohamud an impostor.

Passport Canada spokesman Sebastien Bois says any passport which has been the subject of a prosecution will not be returned and remains the property of the Canadian government.

Mohamud returned to Canada on Saturday after DNA tests, conducted after Boulakia launched a motion in Federal Court in July, confirmed her identity. She is now receiving medical treatment for a respiratory illness she contracted while jailed in Nairobi.
