And there is an investigation as to whether the legal status of the majority of an entity is considered to be like all of that entity⁷⁶⁴.

Leviticus 4:13 says,ואם כל עדת ישראל ישגו ונעלם דבר מעיני הקהל ועשו אחת מכל מצות יהוה אשר לא תעשינה ואשמו (And if the whole congregation of Israel shall err, the thing being hid from the eyes of the assembly, and do any of the things which the LORD has commanded not to be done, and are guilty), using the phrase כל עדת ישראל for “the whole congregation of Israel”, which means the Sanhedrin. Rule 582 is referring to the question as to whether this verse means each and every member of the Sanhedrin errs in judgement or only the majority of the Sanhedrin errs in judgement.
