The Mullaithivu district judge M S M Samsudeen yesterday asked the army to submit the list by January 30, KS Ratnavel, an attorney said.
The magisterial order came as a Habeas Corpus case was heard in respect of those LTTE members who had allegedly disappeared after surrendering.
The military at the previous hearing had said they were in possession of a list of those who had surrendered.
The government said it had successfully rehabilitated over 8,000 of the LTTE cadres who had surrendered.
According to the UN figures, up to 40,000 Tamil civilians were killed by security forces during the Mahinda Rajapaksa's regime that brought an end to the nearly three decades-long war with the defeat of the LTTE.
