@Plumtree391 not just anyone, she sued Alan Dershowitz, Harvard law professor and famous US lawyer, who has been involved in any number of celebrity cases. As you might imagine that lawsuit is bogged down in numerous procedural battles.
Which, to be honest, is what I expect will happen here. You can’t just sue someone in New York courts for actions that happened in the UK when the defendant still lives in the UK. Andrew’s lawyers will (quite properly, as a matter of law) claim that the New York court does not have jurisdiction in this matter. I suppose it’s quite possible that Andrew could also claim that in 2001, as an official trade envoy, he had diplomatic immunity at the time? Plenty of procedural attacks to raise, then. And even if the New York court decides it has jurisdiction and grants a judgment against him, if he has never submitted to its jurisdiction, it won’t be enforceable against him.
Given all this, which Ms Guiffre’s lawyers will obviously know, it is quite likely that the lawsuit has been filed to put pressure on the Prince to pay her a sum of money to make it go away. I guess it depends on how much he thinks he has a reputation worth saving? I mean I think he’s long past any kind of rehabilitation, personally, so in his shoes I’d probably not be minded to engage with the case. His ego may not help him decide to play the long game, however.
