According to ancient Jewish law if a panel of the Sanhedrin (23 Jewish judges) unanimously find a defendant guilty of murder then they must acquit.
The CDC ACIP voted 14-0 without discussion or having read the evidence.
The underlying assumption behind the "Sanhedrin rule" is that, in this situation, the Sanhedrin’s judgement may be systematically biased, and hence the judgements may be dependant, one on another, rather than each judgement produced independently.
Hence a 14-0 judgement should, logically, using Bayesian analysis, increase your belief that the CDC ACIP decision was systematically biased.
