They did rule against it, in deference to the Swedish Legal System, which, according to your explanation, gives the prosecutor the discretion to have the interview locally or overseas. That is, why not remove one of Assange's complaints and have the interview in GB, if it is in her power to do so? It would give him one less leg to stand on. He would still wind up in Sweden, and they would still be able to refer back to the witnesses for a response to his interview.
Oh, come on. Why do you ignore half of what's talked about all the time?
It's in her power, but she has explained that it would not be suitable to do it this way, partly since there might be additional needs in relationship to the interview, partly since she expects to charge him. English courts accepted this argument, and ruled against JA. You can't just keep saying "but" - you need a solid legal argument to take this forward.
