Which of the following is NOT an exception to client confidentiality?

The option indicating the ability to disclose any information without exceptions is correct because it fundamentally contradicts the principles of client confidentiality that govern the attorney-client relationship. Client confidentiality is a cornerstone of legal ethics, ensuring that clients can speak freely and candidly with their lawyers without fear that their private information will be disclosed.

Confidentiality is only subject to specific exceptions, which are outlined in the other options. For instance, disclosing information to prevent serious injury or death acknowledges the lawyer's responsibility to protect the public. Discussions within a law firm for internal purposes typically permit lawyers to communicate with one another regarding case matters, as long as confidentiality is maintained within the firm. Additionally, informed consent from the client allows lawyers to disclose information if the client agrees, reinforcing the importance of the client’s autonomy and decision-making power regarding their own information.

Therefore, the correct answer highlights the principle that, generally, attorneys cannot disclose client information without following established exceptions, underscoring the inviolable nature of client confidentiality in legal practice.
