I’m not a lawyer, but this is what I understand.
All correspondence of the OC is the property of the OC and as such can be accessed by any lot owner.
The only caveat is that a lot owner who is taking the OC to court is barred from seeing the legal correspondence associated with the case ( until the matter is settled, which would include any appeals).
If I was on this committee, I would limit the people who have access to the legal documents to those who are running the case. Usually one or two people are elected to speak with the lawyers.
What you do not want is an associate of the aggrieved lot owner to access legally privileged documents and pass that to the aggrieved owner.
Not all lot owners are going to side with the OC nor with the aggrieved lot owner.
