What is the test for reviewing an extradition order on a petition for habeas corpus?

In reviewing an extradition order on a petition for habeas corpus, our role is strictly limited. We only review to determine (1) whether the extradition court had jurisdiction over the proceedings and the fugitive, (2) whether the offense charged is within the valid and enforceable extradition treaty, and (3) whether there was any evidence warranting the finding that there was a reasonable ground to believe the accused guilty. In conducting this review, findings of fact are reviewed under a "clearly erroneous" standard, and legal questions are reviewed de novo.
