The British High Court will serve papers on the prince if necessary, allowing Virginia Giuffre’s suit, filed in New York, to proceed.
In the first hearing in the closely watched case, lawyers for the Duke of York argued that the lawsuit was baseless and legally dubious.
Virginia Giuffre, one of Jeffrey Epstein’s most prominent accusers, sued the prince in New York, saying that he raped and sexually abused her when she was 17.
Jean-Luc Brunel, 74, is also being investigated on suspicion of human trafficking of minors for sexual exploitation, the Paris prosecutor said.
Ms. Maxwell, who fought to keep the deposition secret, repeatedly denied that she helped Jeffrey Epstein recruit, groom and sexually abuse young women.
Lawyers for the prince consulted a lobbyist with connections in Trump foreign policy circles. No deal was struck.
