Mass. Gen. Laws ch. 277, § 14A: Right to counsel; grand jury proceedings

Section 14A. Any person shall have the right to consult with counsel and to have counsel present at every step of any criminal proceeding at which such person is present, including the presentation of evidence, questioning, or examination before the grand jury; provided, however, that such counsel in a proceeding before a grand jury shall make no objections or arguments or otherwise address the grand jury or the district attorney. No witness may refuse to appear for reason of unavailability of counsel for that witness.
