Which of the following is NOT considered a duty owed to others by a lawyer?

Confidentiality is actually considered a fundamental duty that a lawyer owes to clients, not to others in general. It involves the obligation to protect the information related to the representation of a client. This duty is crucial in maintaining the trust of clients and upholding the integrity of the attorney-client relationship.

On the other hand, duties like dignity/decorum, fairness, and honesty, while important aspects of a lawyer's conduct, are principles that can extend beyond just the lawyer-client relationship and pertain to interactions within the legal system and with other lawyers, judges, and the public. For instance, dignity and decorum pertain to a lawyer’s conduct in court, demonstrating respect for the legal process. Fairness relates to the obligation to treat all parties in a legal matter with respect, ensuring an equitable approach in legal proceedings. Honesty is crucial in all dealings, requiring lawyers to be truthful in their representations and dealings with others.

Therefore, while confidentiality is a central tenet of client protection, it does not extend to duties owed to others in a general sense, making it the correct choice in this context.
