What principle does Rule 1.6 promote regarding client information?

Rule 1.6 of the ABA Model Rules of Professional Conduct is focused on the protection of client confidentiality and privacy. This rule establishes the fundamental principle that attorneys must maintain the confidentiality of information related to the representation of a client. It underscores the attorney-client privilege, which is a cornerstone of the legal profession, allowing clients to communicate openly with their lawyers without fear that their statements could be disclosed to others.

By ensuring that client information remains confidential, Rule 1.6 promotes trust and encourages clients to share sensitive information necessary for effective legal representation. This confidentiality is essential for the legal process as it allows attorneys to provide informed and competent counsel.

Options discussing mandatory reporting, full disclosure to opposing parties, or discretionary sharing with colleagues would conflict with this principle of client confidentiality established by Rule 1.6. The emphasis is clearly on safeguarding the client's private information against disclosure, making the protection of client confidentiality and privacy the central tenet of the rule.
