List accuracy and completeness

It’s very important that you be as diligent as you can in gathering NRF data so that the Master Juror Lists are inclusive of the entire Massachusetts population and that certain groups aren’t excluded from the jury selection process. Excluding groups of people by not listing them, or providing inaccurate addresses, could potentially impact criminal convictions and civil verdicts.

The OJC depends on you to make your best efforts to locate all residents and submit the required information for the Master Juror List. We recognize the challenge you face, including budget constraints and non-responsive residents. Nevertheless, the OJC is required to take all necessary steps, including legal action if necessary, to ensure that all 351 Massachusetts cities and towns are in full compliance with Mass. General Laws c.51, §4 and c.234A, §10 .

Please contact this Office immediately if you encounter any difficulties or foresee any problems with your town’s ability to meet its obligations.

The Massachusetts Jury System is widely regarded as the “gold standard” among all states precisely because we have access to the most complete resident information through the annual census. It is your commitment to conducting a complete and accurate census that enables Massachusetts to maintain its position as the national benchmark, and we thank you for that commitment.

It is important to remind municipalities that the OJC will file suit, if necessary, as we did in Boston and more recently had to threaten in New Bedford. We also want to leave the explanation of the importance of the census, the position MA occupies nationwide because of it, and thank them for the role they play in maintaining that position.
