Comment - Rule 3.06
1. To safeguard the impartiality that is essential to the judicial process, veniremen and jurors should be protected against extraneous influences. When impartiality is present, public confidence in the judicial system is enhanced. There should be no extrajudicial communication with veniremen prior to trial or with jurors during trial or on behalf of a lawyer connected with the case. Furthermore, a lawyer who is not connected with the case should not communicate with or cause another to communicate with a venireman or a juror about the case. After the trial, communication by a lawyer with jurors is not prohibited by this Rule so long as he refrains from asking questions or making comments that tend to harass or embarrass the juror or to influence actions of the juror in future cases. Contacts with discharged jurors, however, are governed by procedural rules the violation of which could subject a lawyer to discipline under Rule 3.04. When an extrajudicial communication by a lawyer with a juror is permitted by law, it should be made considerately and with deference to the personal feelings of the juror.
2. Vexatious or harassing investigations of jurors seriously impair the effectiveness of our jury system. For this reason, a lawyer or anyone on his behalf who conducts an investigation of veniremen or jurors should act with circumspection and restraint.
3. Communications with or investigations of members of families of veniremen or jurors by a lawyer or by any one on his behalf are subject to the restrictions imposed upon the lawyer with respect to his communications with or investigations of veniremen and jurors.
4. Because of the extremely serious nature of any actions that threaten the integrity of the jury system, a lawyer who learns of improper conduct by or towards a venireman, a juror, or a member of the family of either should make a prompt report to the court regarding such conduct. If such improper actions were taken by or on behalf of a lawyer, either the reporting lawyer or the court normally should initiate appropriate disciplinary proceedings. See Rules 1.05, 8.03, 8.04.
