The plaintiffs, inmates at the Massachusetts Correctional Institution at Cedar Junction at the time they filed their complaint, appeal from a summary judgment in favor of the defendants. The motion judge rejected the inmates’ chal *831 lenge to disciplinary board decisions that resulted in their loss of days of good-time credit against their sentences. The plaintiffs were charged in nearly identical disciplinary reports with killing another inmate at M.C.I., Norfolk. The correction officer who filed the reports relied on information provided him by inmate informants. 3 The identity of the informants was disclosed neither in the reports nor in the course of the disciplinary hearings held on the charges against each inmate. The disciplinary board found both inmates guilty. Murphy forfeited 150 days of good-time credit against his sentence. Shepard lost 130 days.
We transferred the inmates’ appeal to this court. We affirm the judgment for the defendants.
1. The inmates argue that, in disciplinary proceedings based largely on statements made to the reporting officer by informants, the confrontation clause of art. 12 of the Massachusetts Declaration of Rights guarantees inmates the right to face and cross-examine the informants before good-time credits may be revoked. They assert that no person “shall be held to answer for any crimes or offence” unless given the opportunity to meet
*832
the witnesses against him face to face.

They recognize that the confrontation clause of the Sixth Amendment, applicable through the Fourteenth Amendment, does not aid them here. See
Wolff
v.
McDonnell,
Article 12 does not grant an inmate subject to prison disciplinary proceedings a constitutional right to confront inmate informants whose information appears to have provided the factual basis for the charges. We regard the difference in wording between art. 12 and the Sixth Amendment to be insignificant in these circumstances. The principle underlying each provision is the same. Prison disciplinary proceedings do not involve all the constitutional principles applicable to criminal proceedings, such as proof beyond a reasonable doubt and the right to trial by jury. The need for fairness in disciplinary proceedings must be accommodated to the interest of maintaining prison security. Wolff v.
McDonnell, supra
at 566-567.

2. Although we reject the inmates’ construction of the confrontation clause of art. 12, we do acknowledge that concepts of due process of law expressed in art. 12 are applicable to prison disciplinary proceedings. See
Nelson
v.
Commissioner of Correction,
3. We consider, therefore, the inmates’ claim that the evidence did not support the disciplinary board’s conclusions. We treat this as an action in the nature of certiorari pursuant to G. L. c. 249, § 4 (1984 ed.), even though the complaint speaks in terms of an action for declaratory and injunctive relief. See
Hill
v.
Superintendent, Mass. Correctional Inst., Walpole,
*834
The inmates complain that all the evidence against them was hearsay and assert that hearsay alone can never constitute substantial evidence. Under the State Administrative Procedure Act (G. L. c. 30A), this court has left that question undecided. See
Augustine
v.
Director of the Div. of Employment Sec.,
Considering the testimony of the reporting officer as to specific factual information he received from the informants, together with the other indicia of reliability and credibility that such hearsay must meet
(Nelson
v.
Commissioner of Correction,
4. Other arguments of the inmates can be disposed of briefly, (a) There was no constitutional violation in holding the disciplinary proceedings while the district attorney was investigating the crime, even though as a result each inmate chose not to testify. See
Baxter
v.
Palmigiano,
Judgment affirmed.
Notes
Each report, which the correction officer testified was based on information from two reliable informants (although the report reads as if there had been only one informant), sets forth the following facts in description of the offense: “At approximately 9:00 a.m. on 5/10/80 an informant told me that while playing cards on the first floor of Unit 4-1 on 5/4/80 he heard yelling and banging going on, on the second floor. The time was about 9:00 p.m. Around 9:05 p.m., the same evening, the card game broke up and the informant went to the second floor where he lives. The informant saw inmates Kevin Murphy and Alfred Sheppard standing in front of Ronald Bonner’s Room 2-12. Murphy and Sheppard were yelling at Bonner. Sheppard then left, went into a room and came out with a weapon (table leg) and then Sheppard and Murphy entered Bonner’s room. The informant heard banging coming from Bonner’s room. A couple minutes later the informant saw Murphy and Sheppard leaving Bonner’s room. Murphy was holding the weapon at this point. At this point in time, the informant went up to the third floor to see an inmate and told him that something was going on, on the second floor. After several minutes everything seemed to quiet down and the informant went back to the second floor. As a direct result of this assault, inmate Ronald Bonner died on May 12, 1980 while at Peter Bent Brigham Hosp. The actual date of the issuing of this D-Report is based upon an on-going investigation.”
The record indicates that Shepard signs his name with one “p.”
The applicable language of art. 12 is as follows: “No subject shall be held to answer for any crimes or offence, until the same is fully and plainly, substantially and formally, described to him; or be compelled to accuse, or furnish evidence against himself. And every subject shall have a right to produce all proofs, that may be favorable to him; to meet the witnesses against him face to face, and to be fully heard in his defence by himself, or his counsel, at his election.
