"Mr Mahmudi has received written deaths, from Libyans, and asked for authorisation from the court not to leave Mornaguia", a prison near Tunis where he is being held, his attorney Mabrouk Kourchid told AFP.
The court, refusing to overturn an earlier ruling, approved the Libyan request to extradite Mahmudi, who had been battling the decision on the grounds that he has formally applied for refugee status.
The decision, which was widely expected, leaves Mahmudi with no further legal recourse but his extradition can only take place after the Tunisian president approves it.
The 70-year-old Mahmudi, prime minister until the final days of the regime of the late Libyan leader Moamer Kadhafi, was arrested on September 21 on Tunisia`s southwestern border with Algeria and jailed for illegal entry.
Amnesty International earlier this month urged Tunisia not to extradite Mahmudi, saying he risked being subject to "serious human rights violations". (AK)
