We are presented for the first time with the question whether a minor child may be compelled to appear and to testify, over the objection of both the child and the child’s parents, before a grand jury that is investigating the possible murder of a nonfamily member by the child’s father. We conclude that, in these circumstances, a minor child has no privilege to refuse to appear. Further, the child has no privilege to refuse to testify as to what he may have seen or heard, except perhaps as to confidential communications between the child and the parents, a question we need not decide on this record.

The plaintiffs, twelve, fourteen, and fifteen years of age, live with their parents. The children were subpoenaed to appear on April 4, 1983, to testify before a grand jury that *358was investigating the possible murder of a missing woman. The woman was an acquaintance of their father, and the investigation had focused on him. Neither the children nor their parents wish the children to appear or to testify. On April 4, the children moved to quash the subpoenas, claiming a family or parent-child privilege not to testify. A judge of the Superior Court denied the motion, but stayed the appearance of the children before the grand jury until April 14.

On April 13, the children filed a petition under G. L. c. 211, § 3, in the Supreme Judicial Court for the county of Suffolk seeking reversal of the denial of their motion. A single justice allowed the parents to intervene. The Commonwealth submitted an affidavit to the single justice in support of its contention that the children’s expected testimony would be relevant to the grand jury investigation. The affidavit, which has been impounded, states in part that, “there is reason to believe that [the missing woman] was murdered on the evening of March 5 . . . and that an examination by the Grand Jury of the above mentioned children ... as to their observations of the comings and goings of their parents and in particular [the father and the missing woman] during this critical period of time, as well as any conversations they may have witnessed between them could . . . provide further evidence pertaining to her murder.” The single justice further stayed the witnesses’ appearances, and reserved and reported the case, without decision, for determination by the full court, presenting three questions for our consideration.

The case was argued before the full bench on May 5, 1983, and on August 4, 1983, we issued an order which is set forth in the margin.2 We concluded that (1) the motion *359j'udge properly denied the children’s motion to quash the subpoena; (2) the children had no constitutional or other right not to appear and testify before the grand jury, leaving open, however, the question of their obligation to testify concerning confidential communications with their parents; and (3) the parents had no constitutional or other right, alone or in conjunction with their children, to prevent their children from appearing and testifying.

Testimonial privileges “are exceptions to the general duty imposed on all people to testify.” Commonwealth v. Corsetti, 387 Mass. 1, 5 (1982). Matter of Pappas, 358 Mass. 604, 607-609 (1971), aff’d sub nom. Branzburg v. Hayes, 408 U.S. 665 (1972). Such privileges diminish the evidence before the court (Commonwealth v. Corsetti, supra), and contravene the fundamental principle that “the public . . . has a right to every man’s evidence.” United States v. Bryan, 339 U.S. 323, 331 (1950), quoting 8 J. Wigmore, Evidence § 2192, at 64 (3d ed. 1940). As such, they must be strictly construed (see Commonwealth v. Corsetti, supra), and accepted “only to the very limited extent that permitting a refusal to testify or excluding relevant evidence has a *360public good transcending the normally predominant principle of utilizing all rational means for ascertaining truth.” Elkins v. United States, 364 U.S. 206, 234 (1960) (Frankfurter, J., dissenting). Except for the privilege against self-incrimination (Branzburg v. Hayes, 408 U.S. 665, 689-690 [1972]; Matter of Roche, 381 Mass. 624, 634 n.11 [1980]), and a limited “executive privilege” (United States v. Nixon, 418 U.S. 683, 709-710 [1974]), testimonial privileges have generally not been based on a constitutional right. The question “we must decide [is] whether the privilege against adverse [parent-child] testimony promotes sufficiently important interests to outweigh the need for probative evidence in the administration of criminal justice.” Trammel v. United States, 445 U.S. 40, 51 (1980). See Matter of Pappas, supra at 609, quoting Professor Edmund M. Morgan in his preface to the American Law Institute’s Model Code of Evidence (1942).

We are, of course, free to identify a privilege of a child not to testify against his or her parent. Such a privilege could be based on common law or constitutional principles.3 In recent years, however, courts have tended to leave the creation of evidentiary privileges to legislative determination.

We have recognized common law testimonial privileges, as a matter of public policy, such as the attorney-client privilege (Foster v. Hall, 12 Pick. 89, 97 [1832]), and the government informer privilege (Worthington v. Scribner, 109 Mass. 487, 489, 493 [1872]). Some members of this *361court have expressed a willingness to consider recognizing a news reporter’s privilege. See Matter of Roche, 381 Mass. 624, 638-640 (1980). The Legislature has also recognized certain testimonial privileges. See G. L. c. 233, § 20A (certain communications to a clergyman); G. L. c. 233, § 20B (certain communications between a psychotherapist and a patient); G. L. c. 112, § 135 (certain communications to a social worker). All these statutory and common law privileges involve communications made in confidential circumstances. They do not involve disqualifications from testifying.

The Legislature has recognized a testimonial disqualification as to certain private conversations between spouses. G. L. c. 233, § 20, First. It has granted one spouse the right to elect not to testify against the other spouse in a criminal proceeding (except in a proceeding relating to child abuse or in an action for nonsupport). G. L. c. 233, § 20, Second, as appearing in St. 1983, c. 145. There is, however, no privilege for a spouse not to testify against the other spouse in a civil action, even if that testimony may be highly destructive of the marital relationship. The Legislature has not chosen to establish a parent-child testimonial privilege or disqualification. It has, however, been willing to recognize problems presented to family members by criminal conduct of another family member. See G. L. c. 274, § 4 (exemption of certain family members from criminal liability as accessories after the fact for harboring a family member after his commission of a felony).

In our order of August 4, 1983, we expressly declined to rule on the question of a privilege as to “alleged confidential communications between the parents and their children.” We adhere to that determination. Although there is limited support for a testimonial privilege to protect confidential communications from child to parent, the weight of authority is against it.4 Because a parent does not need the *362advice of a minor child in the same sense that a child may need the advice of a parent, the case for a testimonial privilege as to confidential communications from parent to child seems weaker than the case as to such a communication from child to parent. We are aware of no State that, through legislation or by a decision of its court of last resort, has recognized any privilege that would protect a child from testifying against a parent concerning the parent’s confidential communications to the child. In any event, the case before us does not currently involve, and may never involve, the question of confidential communications between parent and child.5

A clear majority of the courts that have considered whether there is a general privilege of a child not to testify against his or her parent have found no such privilege. Understandably, there should be no privilege when a parent is charged with physically abusing the child (Hunter v. State, 172 Ind. App. 397, 410, cert. denied, 434 U.S. 906 *363[1977]), or where a family member may otherwise be the victim of wrongdoing. Where the focus of inquiry involves the conduct of a parent, courts have almost universally declined to recognize a privilege. See United States v. Jones, 683 F.2d 817, 818-819 (4th Cir. 1982); United States v. Penn, 647 F.2d 876, 885 (9th Cir. 1980) (“There is no judicially or legislatively recognized general ‘family’ privilege”); In re Grand Jury Proceedings, 647 F.2d 511, 512-513 (5th Cir. 1981) (per curiam); State v. Gilroy, 313 N.W.2d 513, 516 (Iowa 1981). We are aware of only one opinion that has recognized not only a privilege of a child not to testify against his father as to confidential communications but also a privilege not to testify against his father at all in a criminal proceeding. In re Grand Jury Proceedings Witness: Agosto, 553 F. Supp. 1298 (D. Nev. 1983). This prolix opinion of a single Federal judge demonstrates the judge’s concern for the preservation of the American family but cites no authority or persuasive policy reason for such an extreme position. It is this extreme position — an absolute privilege not to testify at all — that we reject.6

*364In the last analysis, the question comes down to a balancing of the public’s interest in obtaining every person’s testimony against public policy considerations in favor of erecting a testimonial privilege in the circumstances. We have put to one side the question of confidential communications between parent and child and thus are concerned here only with what the children may have seen and heard in nonconfidential circumstances. Confidential communications aside, we see no basis for concluding that a constitutional right of privacy requires that the children and their parents be given a testimonial privilege. Neither Congress nor the Legislature of any State has seen fit to adopt a rule granting a privilege to one family member not to testify against another (except between spouses) or even to grant a privilege not to testify as to confidential communications between family members (again, except as to spouses). Courts have been generally reluctant to identify any such privilege, and, as far as we can tell from reported decisions, only one judge in this country has found an absolute privilege of a child not to testify against a parent as to nonconfidential matters. Society’s interest in the preservation of the family does not require such a broad rule, either as a matter of common law privilege or constitutional right. The exclusion of testimony concerning the parents’ nonconfidential words and deeds would not promote “sufficiently important interests” so as “to outweigh the need for probative evidence in the administration of criminal justice.” Trammel v. United States, 445 U.S. 40, 50-51 (1980). In the circumstances of this case, the Commonwealth’s interest in obtaining all relevant information concerning the disappearance of a young woman who may have been murdered must predominate over generalizations favoring the preservation of the American family through barring a child from testifying about nonconfidential matters involving his or her parent.

(dissenting, with whom Hennessey, C.J., and Lynch, J., join). The court has declined to create a tes*365timonial privilege that would protect unemancipated minor children from being coerced by the State to appear and to testify, over the objection of the children and their parents, before a grand jury that is investigating the possible murder of a nonfamily member by the children’s father. The court reaches this conclusion despite its acknowledgment that it is “of course, free to identify a privilege of a child not to testify against his or her parent.” Supra at 360.

Correctly recognizing that its task is to balance the public’s interest in obtaining every person’s testimony against public policy considerations in favor of erecting such a testimonial privilege, supra at 364, the court concludes that in the circumstances presented by this case a minor child has no privilege to refuse to appear before a grand jury or to refuse to testify as to what he or she may have seen or heard, except perhaps as to confidential communications between the child and the parents. Supra at 357. The court reasons that erecting the privilege “would not promote ‘sufficiently important interests’ so as ‘to outweigh the need for probative evidence in the administration of criminal justice.’ Trammel v. United States, 445 U.S. 40, 50-51 (1980).” Supra at 364. I respectfully, but firmly, disagree with the court’s reasoning and with its conclusion. The violence done to the child, the damage to family unity, and the consequent injury to society that may result from the State’s coercing an unemancipated minor to testify against a parent in the circumstances of this case are too high a price to pay for the enforcement of our criminal laws.

Although the court reasons that the privilege would not promote sufficiently important interests to warrant depriving the Commonwealth of evidence that might aid its investigation, the opinion fails to compare adequately the values that compete for protection by the court. Legitimate concerns about the impact of the court’s determination on children, families, and society are summarily dismissed. Instead, the court relies on what it perceives to be the weight of authority against judicial creation of a parent-child testimonial privilege, and the lack of substantial precedent favor*366ing such a privilege. Supra at 362-363. There is little helpful precedent. Such precedent as there is provides no justification for the court’s failure to create a parent-child testimonial privilege in this case. A proper balancing of the values that are involved yields the conclusion that the privilege for which the plaintiffs contend should have been granted.

The court has ruled that a child must appear before a grand jury and may be required to testify in the circumstances of this case. The significance of the court’s decision, however, would appear not to be limited to the circumstances of this case. The fair import of the decision is that, with the possible exception of confidential communications between parents and their children, and in the absence of concerns about self-incrimination, this Commonwealth does not recognize the right of a child to refuse to testify before a grand jury against his or her parent with respect to observations made inside or outside the home, having possible bearing on any kind of crime, violent or nonviolent, “white collar” or otherwise.

The State should not make unrealistic demands on its citizens, especially its children. A requirement that an unemancipated minor child, living with his or her parents, must incriminate one or both of them is an unrealistic demand, at least when a family member is not a victim of the crime under investigation. The demand is unrealistic because it is insensitive to the needs of children, and to the nature of the normal relationship between children and their parents, involving, as it does, love, trust, loyalty, and dependency. This court should recognize a public policy against imposing on the conscience of a child responsibility for incriminating his or her parent. Society’s interest in its children should be recognized as sufficiently important to outweigh the need for probative evidence in the administration of criminal justice in the circumstances presented by this case.

Not only does society have an interest in children’s being free from unreasonable public demands, but society also has an interest in fostering the unity of the family. “[T]he insti*367tution of the family is deeply rooted in this Nation’s history and tradition.” Moore v. East Cleveland, 431 U.S. 494, 499, 503-504 (1977). The Massachusetts Legislature has declared that “the policy of the commonwealth [is] to direct its efforts ... to the strengthening and encouragement of family life.” G. L. c. 119, § 1, as amended by St. 1972, c. 785, § 5. The Legislature has granted one spouse the right not to testify against the other spouse in a criminal proceeding except in child abuse and nonsupport cases. G. L. c. 233, § 20. General Laws c. 274, § 4, exempts specified family members from criminal liability as accessories after the fact to the commission of a felony by other members of the same family. These statutes demonstrate a legislative awareness that there are basic human instincts to protect the members of one’s family, even from the State, and that the State should respect those instincts, despite the possible adverse effect on law enforcement. These statutes also demonstrate a legislative judgment that in some circumstances the important interests of society in obtaining every person’s evidence must give way to the recognition and protection of marital and family integrity. If society’s interest in the enhancement of the marriage relationship justifies a spouse’s privilege not to testify against a spouse in a criminal proceeding, a corresponding interest in family integrity must justify, with at least equal force, an unemancipated minor’s privilege not to testify in the circumstances presented by this case. Furthermore, if public policy dictates that family members should be protected from criminal liability for shielding other family members from apprehension for felonious conduct, all the more does public policy call for the grant to a child of a privilege not to testify against his or her parent in the circumstances of this case.

That the Legislature has not seen fit to grant such a privilege is not an adequate answer. It may be that the necessity for such legislation has not come to the Legislature’s attention. Perhaps prosecutors have heretofore refrained from forcing the issue. In any event, this court has the power to create testimonial privileges in appropriate circumstances. *368For the reasons I have stated, and for the additional reason that the enforceability of a rule requiring a child to testify against his or her parent is very doubtful, I believe that the court’s order was erroneous.

I comment briefly on the precedents cited by the court. Nearly all of the cases which have rejected claims of a parent-child privilege can be distinguished from this case. The courts that decided In re Terry W., 59 Cal. App. 3d 745 (1976), Cissna v. State, 170 Ind. App. 437 (1976), followed by Hunter v. State, 172 Ind. App. 397, cert. denied, 434 U.S. 906 (1977), and State v. Gilroy, 313 N.W.2d 513 (Iowa, 1981), reasoned that only the Legislature, and not the court, was authorized to grant testimonial privileges. In this Commonwealth, however, there is no bar to the creation of a common law privilege in appropriate circumstances, so those cases give us no assistance whatsoever.

Cases in which the court has considered and rejected a general common law privilege of a child not to testify against his or her parent are significantly distinguishable on their facts from the present case. In Matter of a Grand Jury Subpoena Served Upon Kinoy, 326 F. Supp. 400 (S.D.N.Y. 1970), the family member about whom the grand jury sought information was not a target of the grand jury investigation, but was sought in connection with an investigation of another individual. Also the parent and child did not live together. That is unlike the present case in which the grand jury investigation has focused on the father, with whom the children live. In United States v. Jones, 683 F.2d 817, 819 (4th Cir. 1982), the court held that “[ujnder the circumstances, namely an emancipated, adult child’s testimony which only arguably would be adverse to his father, limited to questions unrelated to his familial association with his parent, and involving no communication between father and son, we are satisfied that there simply is no privilege such as Jones has asserted. See In re Kinoy, 326 F. Supp. 400, 406 (S.D.N.Y. 1970).” In United States v. Penn, 647 F.2d 876 (9th Cir. 1980), a majority of the Court of Appeals, sitting en banc, reversed a Federal District Court or*369der granting the defendant’s motion to suppress a jar of heroin taken from the defendant’s backyard. The Court of Appeals held that the conduct of the police in offering the defendant’s five year old son $5 if he would show them the location of the heroin did not violate due process, and that the seizure of the heroin, did not violate the Fourth Amendment to the Constitution of the United States. At the conclusion of its opinion, the court considered the defendant’s claim of privilege. It stated simply: “There is no judicially or legislatively recognized general ‘family’ privilege . . . and we decline to create one here.” Id. at 885. That case did not involve a child’s compelled testimony against a parent. In In re Grand Jury Proceedings, 647 F.2d 511 (5th Cir. 1981), the opinion does not reveal whether the daughter, called as a witness, was a minor, was emancipated, or was living with her parents.

The court fails to cite a single case in which a court that has recognized its authority to grant testimonial privileges has undertaken a comparison of the competing values presented by a case such as this one, and concluded that the interest of the State in obtaining evidence is entitled to priority over the interests of children, families, and society that would be served by granting the privilege for which the plaintiffs contend. However, there is one recent case in which the court did balance the competing interests, and held that, as a matter of constitutional law, a child of any age may claim the parent-child privilege and refuse to appear and give any testimony whatsoever against his or her parent in any criminal proceeding. See In re Grand Jury Proceedings Witness: Agosto, 553 F. Supp. 1298 (D. Nev. 1983). The court reasoned that the government’s interest in presenting all relevant evidence in criminal proceedings was outweighed by the individual’s interest in the privacy of family communications and the family’s interest in its integrity and inviolability. Maintaining the harmony and privacy of the family relationship, the court concluded, was just as compelling a goal as maintaining the harmony and privacy of the marriage relationship, which is protected by *370the husband-wife privilege. Id. at 1325. The court emphasized that placing a child in the position of being “scorned and branded as disloyal if he does testify and jailed if he does not” would undermine the unity of the family and would risk grave psychological harm to the child. Id. at 1326. I do not consider that opinion unpersuasive here, although it goes beyond the necessities of the case before us. I would have ruled in this case that unemancipated minor children, living with their parents, should not be compelled either to appear or to testify, before a grand jury that is investigating the possible murder by their father of a non-family member.
