Opinion 538

Question Presented

Is a lawyer, who is the newly elected district attorney, prohibited from prosecuting a motion seeking to revoke the probation of a former client in a case where the lawyer served as defense counsel for the former client in the original proceeding?

Is a lawyer, who is the newly elected district attorney, prohibited from prosecuting a former client in a new criminal proceeding?      

If not so prohibited, is the lawyer, as the newly elected district attorney, prohibited from offering in evidence a prior conviction in which the lawyer was defense counsel in the prior proceeding for purposes of:

  1. impeachment of the former client under TEX. R. EVID. 609, or
  2. showing character of the former client under TEX. R. EVID. 404(b) or,
  3. punishment evidence under TEX. CODE CRIM. PROC. Art. 37.07 § 3(a)?

For the past twelve years, a lawyer, as a duly appointed state public defender, has defended indigent persons in a myriad of state felony, misdemeanor and juvenile criminal offenses in a certain judicial district. Now the lawyer has been elected district attorney for that judicial district, and will be responsible for the prosecution of all persons in felony criminal cases in that district. It must be assumed that the lawyer, as the newly elected district attorney, will be required to prosecute former clients in new criminal proceedings as well as prosecute former clients in probation revocation cases where the lawyer was the defense counsel in the original proceeding.
