Problem: A sole practitioner has a busy personal injury practice. Although for the past six months very little has been happening with her case, a client has been calling the lawyer every day for updates on the status of her litigation. At first, the lawyer acknowledged each call and responded promptly. Lately, however, he has not responded to her numerous calls, letters, and emails on a daily basis. Instead, the lawyer explained to the client that he would be updating her once every two weeks unless something arose that required her attention. The client is unhappy. Has the attorney violated the Model Rules of Professional Conduct? Question 1 options: a) Yes, unless his failure to respond to the client's inquiries is due to illness, injury, or other disability. b) Yes, because an attorney must promptly acknowledge all contacts by a client. c) No, because he kept the client reasonably informed. d) No, if the client is also an attorney or possesses significant legal knowledge.
