So none of the opinions the defense got from their experts are discoverable? That would be surprising to me.
So far that's what it means.
If the expert produces a report the report needs to be shared. If they just have a friendly email chat about it, then it's work product. I really kind of thought Nelson wasn't going to look at the emails in the second folder MOM handed her, it was an inch or more thick, but I think she read (or at least skimmed) every one before ruling they were work product. Ruefully, I might add.
