"The alternative being that they reviewed a small portion of said documents, which would render their argument completely moot, since they would only need to release the documents they actually used during their decision"
This is incorrect - this is not actually what they requested.
Look at the complaint (https://fingfx.thomsonreuters.com/gfx/legaldocs/klvykdlryvg/...), paragraph 5
CFR (code of federal regulations) says:
"“After a license has been
issued, the following data and information in the biological product file are immediately available
for public disclosure unless extraordinary circumstances are shown: (1) All safety and
effectiveness data and information. (2) A protocol for a test or study . . .” 21 C.F.R. § 601.51(e)."
They requested all data that 21 CFR 601.51 authorizes, except for the adverse reaction reports available in the VARS database.
So whether the FDA reviewed or relied on all 329,000 pages, they are requesting all 329,000 pages.
Worse, of course, is that they deliberately ...'d the part that makes it take so long (this will, btw, piss off the judge and clerk who read the brief, since they will go and read that and see immediately that it happened)
Go look at 21 CFR 601.51(e) and subsequent parts, and you can see the FDA is required to do exactly what they said:
https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFR...
In practice, this is just the posturing phase - 90% of what the plaintiffs requested is probably pointless.
The CFR says "
(g) For purposes of this regulation, safety and effectiveness data include all studies and tests of a biological product on animals and humans and all studies and tests on the drug for identity, stability, purity, potency, and bioavailability."
So like, this is probably tens of thousands of pages of blood pressure and heart rate readings for 10,000 anonymous people kind of thing. Along with tens of thousands of pages of blood test results, etc.
And then tens of thousands of pages of purity testing of random vaccine lots ;)
Usually, the judge will tell both sides to try to figure it out, they will get together and the plaintiffs decide "yeah, maybe we only really need 10k pages" and the defendants decide "yeah, we can do 10k pages in 3-4 months" and the case settles.
It would be super unlikely for the judge to order the FDA to produce 329,000 redacted pages of documents in very short order.
