Upon application of a party or upon the judge’s own initiative, and upon a showing that the interests of economy, efficiency, and justice will be served, the chief judge of the Court of Federal Claims may issue an order authorizing a judge of the court to conduct proceedings, including evidentiary hearings and trials, in a foreign country whose laws do not prohibit such proceedings, except that an interlocutory appeal may be taken from such an order pursuant to
section 1292(d)(2) of this title, and the United States Court of Appeals for the Federal Circuit may, in its discretion, consider the appeal.
