CLEAR AND CONVINCING EVIDENCE:

     An extradition proceeding being sui generis, the standard of proof required in granting or denying bail can neither be the proof beyond reasonable doubt in criminal cases nor the standard of proof of preponderance of evidence in civil cases. While administrative in character, the standard of substantial evidence used in administrative cases cannot likewise apply given the object of extradition law which is to prevent the prospective extraditee from fleeing our jurisdiction. In his Separate Opinion in Purganan, then Associate Justice, now Chief Justice Reynato S. Puno, proposed that a new standard which he termed "clear and convincing evidence" should be used in granting bail in extradition cases. According to him, this standard should be lower than proof beyond reasonable doubt but higher than preponderance of evidence. The potential extraditee must prove by "clear and convincing evidence" that he is not a flight risk and will abide with all the orders and processes of the extradition court.
