[cabfpub] Misissuance of certificates

You made a statement in another email which, if I'm remembering correctly, said something like this: If a cert is issued from a public root, for public domains, for use by the public, then its contents is automatically public.
Is this based on:
1. An authoritative definition? (if so, please cite a reference)
2. A commonly held belief?
3. Your own interpretation?
Also, I think Inigo raised some privacy concerns that may make the above a violation of local laws. Your text below doesn't address that. That may be problematic for a 1 week timeline, especially if there are many domain owners that need to be consulted.
Are you saying that any cert not in compliance with the BRs constitutes misissuance?
In the future, when name redaction is allowed for OV/DV, publishing the full certificate negates the value of name redaction. So for example, consider a case where the cert was issued to the right recipient, but the misissuance was the addition of a misleading OU field, or a "MUST INCLUDE" extension is omitted. The proposal would force CAs to reveal the redacted names.
I think we need to nail down some of this before proceeding to a ballot.

I'd like to ask for two endorsers for this, to put it through a ballot.
I would go into BR section 2.2.
