Thanks for that info, are they planning to ask if he knew she was being trafficked then
No idea. The letter from the judge suggests they want to know what she has said to him regarding Andrew, so I suspect not. I can't immediately see that whether Robert Giuffre knew VG was trafficked is relevant to the case.
its being reported that they have called PA ex equerry even though he wasnt employed at the time
He was Andrew's equerry from 2002-2004. This is after the alleged encounters took place. She is hoping he will be able to reveal information about communications concerning her.
a woman who claims she saw them at Tramp but doesnt know the date
The woman in question says she saw Andrew at Tramps in March 2001 with a woman who may have been VG.
If they find in favour of VG would it mean they reopen the case in the UK which the police dropped
The only crime that Andrew may have committed in the UK is rape. To get a conviction, VG would have to co-operate with the UK police and provide much stronger evidence than she has in anything she has said to date. Remember that, for a conviction, it would be necessary to prove beyond reasonable doubt that she was raped, whereas she could win her civil case on the balance of probability. So, even if the jury in the US decides that Andrew raped VG, that does not mean there is enough evidence to convict him in the US or the UK.
