Final answer:
The attorney could face disciplinary action for disclosing confidential information without consent, as the ethical guidelines of the legal profession, including the Rules of Professional Conduct, require that such information remains confidential unless the client permits disclosure or specific exceptions apply.
Step-by-step explanation:
The ethical dilemma presented revolves around the attorney's duty of confidentiality in relation to privileged communication between attorney and client, as stipulated by the Rules of Professional Conduct.
If the attorney publicly discloses confidential information without consent, even if the information is a matter of public record or not directly related to the legal representation (such as the client's personal affairs concerning their sexuality), they might be subject to disciplinary action.
Ethics require that information gained in the lawyer-client relationship remains confidential unless the client gives informed consent for disclosure, or an exception to confidentiality applies as defined by the rules governing the legal profession.
Cases like Branzburg v. Hayes and Strickland v. Washington touch on related issues of legal ethics and rights to confidentiality, highlighting that privileged information should generally be protected unless overriding legal obligations mandate disclosure.
