The father and son accused of helping former Nissan Motor Co. chairman Carlos Ghosn escape house arrest in Tokyo were denied bail for a third time as they battle an extradition request from Japan.

A federal judge in Massachusetts ruled on Friday that the ex-Green Beret Michael Taylor and his son Peter must remain in custody outside Boston while another judge weighs whether they are eligible for extradition under the U.S. treaty with Japan.

The ruling comes despite the Taylors’ aggressive campaign for bail, with an argument that they have a strong chance of winning their extradition case and that they won’t flee the U.S. But the decision by U.S. District Judge Indira Talwani marked the third time those claims have been rejected since the Taylors’ arrest in May — once by a magistrate and now twice by Talwani.
