Is it a violation of the Code of Ethics for a member of a law firm to hold the office of district attorney, provided no member of the firm takes a case, criminal or civil against the state or county?
18 Baylor L. Rev. 248 (1966)
CONFLICTING INTERESTS - DISTRICT ATTORNEYS
It is not ,improper for an attorney to serve as district attorney without severing his membership in a law firm so long as no member of the firm takes a civil or criminal case against the state or county.
Canon 6.
This inquiry presents a close question. However, a majority of the members of the committee are of the opinion that it would not be a violation of the Canons of Ethics for a member of a law firm to continue as a member of the firm while holding the office of district attorney, provided no member of the firm takes a civil or criminal case against the state or county. Two members so voting suggest, however, that the practice should not be encouraged. (5-4)
