To the best of my knowledge, the 99 page opinion was critical of the FISC Title 1 warrant and the abuses resulting from it.
As always, it's difficult to pin down a time line on so much of what happened in this multi-year cluster____.
It looks as if Judge Collyer's activity might not be related to any specific FISA warrant request. She filed her 99 page opinion on April 26, 2017 and Dan Coates declassified it that same month.
Reading through some of the documents, I don't see how, if at all, Judge Collyer was involved in any of the FISA warrant requests which I think were four in total, and the final one was in lat 2016 or early 2017.
Not clear what judges did preside on the four warrant request proceedings, or when and why Judge Collyer began conducting her reviews that resulted in here 99 page opinion signed in April of 2017.
I guess the facts will eventually be uncovered in all these secret FISA court actions.
