Rule 19-306.2 Accepting Appointments [MARPC 6.2]
An attorney shall not seek to avoid appointment by a tribunal to represent a person except for good cause, such as:
(a) representing the client is likely to result in violation of the Maryland Attorneys' Rules of Professional Conduct or other law;
(b) representing the client is likely to result in an unreasonable financial burden on the attorney; or
(c) the client or the cause is so repugnant to the attorney as to be likely to impair the client-attorney relationship or the attorney's ability to represent the client.
