I will try google later. The article is inconclusive:
It was not clear from Boasberg's own court order which two FISA orders were deemed invalid, but it's likely they were the final two renewals. According to the inspector general's report, the FBI had reason by then to doubt the British spy's information, and it had learned that Page had been cooperating with the CIA.
The article more or less states the first two warrants were accurate and valid when applied for. The review found there was no assessment of new information gained since then prior to applying for renewal representing the final two warrants.
I also think you should read that first article again, when you have findings like this against one of the top justice agencies in the US you have a major problem.
"But he also said he found no satisfactory alternative explanation when it came to the lies and omissions that led a court to wrongly authorize spying on Page, who was not charged with a crime."
LIES AND EMISSIONS. In NZ that is the type of thing that would lead to charges.
