The National Transitional Council has voted for Saif al Islam Gaddafi to be tried in Libya.
Libyan information minister Mehmood Shammam says the decision will be discussed with the International Criminal Court's (ICC) chief prosecutor when he visits Libya on Monday.
Saif is wanted by the ICC on charges of crimes against humanity.
Mr Shammam said it would only be fair for Libyans to try Saif at home where he "committed crimes against Libyan people".
