OK, it appears the prosecutor selected a taint attorney (Jami Brackin) as instructed by the Court, and the defense isn't going to make this easy. This is the second time KR's defense has changed their mind -- citing the envelope contents privileged. We should expect the prosecution seeking a hearing after January 12. MOO
Respectfully, I don't see anything here (in the link you posted, or in the events that have happened) to say the defense has changed their approach.
The argument is over the nature of the contents of the so-called 60-page book. She was caught with a 6 page letter which was confiscated, and which on its face had details for her mother and brother to invent testimony that would help her case. She claimed the 6 page letter was fiction, and part of a 60-page book. When the state asked for the book, as relevant evidence to the question of whether she was trying to solicit false testimony, they were given the runaround by the defense who replied that it was attorney-client privileged.
She is claiming it is BOTH an innocent book, that might one day be published, and at the same time private communications only for her attorneys. That's the essence of the defense's approach, and it has never changed. As to how that's possible (rather than self-contradictory nonsense), the state's not buying it and the judge is delving into it to make a determination.
What has happened so far in that process is that ...
1 the state said "Let us see it, and we can figure out if it is indeed attorney-client privileged material",
2 the defense - and the judge - replied that (a) you cannot be impartial, and (b) once you see its content, there's no way to protect whatever is attorney-client info, as you will already have all of its contents,
3 so the judge appointed an outsider (Brackin, the "taint attorney") to look at the "book" and see if it's the sort of content that needs to be attorney-client protected,
4 Brackin has now looked at it, and said it is not attorney-client stuff at all, and
5 the judge has given the defense 2 weeks to give their argument in writing as to why it SHOULD BE attorney-client.
That's where we are so far. After the defense replies, Brackin will be given a chance (deadline Jan 12) to provide a written response to the defense's arguments. Then there will be a decision made, although it's likely there will also be a hearing in which both sides are heard, with perhaps the state in attendance as well, before the judge rules.
In all of that, the defense's attitude hasn't really changed, consistently being that the "book" proves their side of the story about the 6-page letter, but the state doesn't have the right to see the content of that proof and see if it's a valid claim by Khouri or not, since Khouri gave it to her attorney.
ETA - Interestingly, Khouri using the 6-page letter excuse that "it's all part of a book I'm writing" works strongly against her, in her quest to keep any of it unseen. She is allowed her own private notes, written to be provided to her attorney, but she loses that layer of protection if the end audience is not herself (for her own use) or her attorney.
