In some circumstances, a lawyer may be justified in delaying transmission of information when the client would be likely to react imprudently to an immediate communication. Thus, a lawyer might withhold a psychiatric diagnosis of a client when the examining psychiatrist indicates that disclosure would harm the client. A lawyer may not withhold information to serve the lawyer's own interest or convenience or the interests or convenience of another person. Rules or court orders governing litigation may provide that information supplied to a lawyer may not be disclosed to the client. Rule 3.4(c) directs compliance with such rules or orders. Rule 1.4, Comment (7).
