A judge of the Probate Court reserved and reported two issues raised by the natural parent (mother) 2 at a hearing on the Department of Social Services’ (department) petition to dispense with consent to adoption. G. L. c. 210, §3 (b). At the outset of the hearing the department disclosed to the court the identity of the prospective adoptive family and filed a motion “to compel persons not to reveal the identity of pre-adoptive parents.” 3 The mother filed a motion to dismiss the department’s petition. The judge denied the department’s motion and stayed the effect of the action pending appeal. 4 A single justice of the Appeals Court enjoined counsel for each of the parties and the guardian ad litem from disclosing to the mother either the actual identity of the prospective adoptive family or any information which would lead to the discovery of such identity. 5
Essentially, the mother claims that the department acted illegally in placing the child in the foster care of one of its employees, and, hence, the petition must be dismissed. Alternatively, the mother claims that she is constitutionally entitled to know the identity of the prospective adoptive family. We conclude that the petition should not be dismissed, but that the probate judge should replace the department by appointing a licensed child care agency to take over the investigation and presentation of the petition to dispense with consent. See G. L. c. 210, § 3 (b). We also *709 conclude that the identity of the prospective adoptive family should be withheld from the natural mother. 6
We summarize the interlocutory findings of the probate judge. On November 12, 1974, the natural mother gave birth to the child. At that time the mother was married but living apart from her husband. The parents are still separated, although not divorced or legally separated. Shortly after the mother and child moved to Massachusetts in 1976, the department received a report of suspected abuse or neglect. The child was removed from the natural mother’s custody, pursuant to G. L. c. 119, § 24, and a District Court judge awarded temporary custody of the child to the department. Originally, the child was placed with an authorized foster parent. When that foster home became unavailable in 1977, the foster care was transferred to the home of an employee of the department.
On September 29, 1978, the department filed a petition to dispense with consent to adoption under G. L. c. 210, §3 (b). The department also sought approval of a plan whereby the child would be adopted by one of the department’s employees. 7 In January, 1980, the probate judge appointed a guardian ad litem for the child and separate counsel for the mother.
On September 11, 1980, the mother filed a motion to “construe” the order of the single justice (see note 5, supra), *710 so as to require that the identity of the adoptive parents be disclosed, in order to avoid a violation of her constitutional rights. The Probate Court judge allowed the “motion to construe,” and reserved and reported the issues to the Appeals Court. On March 12, 1981, we granted the application for direct appellate review.
1.
Motion to dismiss.
The mother argues that the placement of the child in the home of one of the department’s employees in 1977 was illegal,
8
or at least improper, and, hence, the petition should be dismissed. She argues by analogy to criminal procedure that we should apply an exclusionary rule to cases “in which agency action with respect to a family has been so arbitrary and irrational as to warrant a dismissal.” The mother claims that her case is such a case. The mother contends that the taking of her child from her in 1977, by the department,
9
and all subsequent proceedings are tainted by the illegal conduct of the department; and, hence, the petition should be dismissed. Even assuming the department’s conduct was illegal (a fact not established on this record), nowhere in her argument of
*711
this issue does the mother give any consideration to the best interests of the child. Any argument that fails to consider the best interests of the child is fatally flawed. “As parens patriae the State does not act to punish misbehaving parents; rather it acts to protect endangered children.”

Although we decline to dismiss these termination proceedings, we believe it would be prudent to disqualify the department from presenting the Commonwealth’s case in these proceedings. In termination proceedings the department’s professional responsibility is to protect the best interests of the child — to strengthen and encourage family life (G. L. c. 119, § 1), as well as, in some instances, to require

Disclosure of the identity of the prospective adoptive family.
The mother argues that in this case we should not follow the Commonwealth’s usual policy of nondisclosure of the identity of the prospective adoptive family. See G. L. c. 210, § 5C. See also
Petition of the Dep’t of Pub. Welfare to Dispense with Consent to Adoption,
The Legislature has determined that the identity of the prospective adoptive parents should be confidential. General Laws c. 210, § 5C, as amended through St. 1972, c. 800, § 6, requires that “[a]ll petitions for adoption, all reports submitted thereunder and all pleadings, papers or documents filed in connection therewith . . . shall not be available for inspection, unless a judge of probate of the county where such records are kept, for good cause shown,
*714
shall otherwise order.”
14
In § 5C, the Legislature indicated its intent to restrict disclosure of information, such as the identity of the adoptive parents,
15
even as to the parties, unless the party seeking disclosure can show good cause. The Appeals Court recognized this legislative policy in
Petition of the Dep’t of Pub. Welfare to Dispense with Consent to Adoption,
The policy of nondisclosure of the identity of prospective adoptive parents is not unique to Massachusetts. See, e.g.,
Cohen
v.
Janie,
*716 The department alleges that the mother has violently attacked and murdered one member of her family (the child’s maternal grandfather), and may still be violent and mentally ill. Thus, the department contends that the possible danger to the prospective adoptive family and the child outweighs any claim to disclosure the mother might make. The single justice agreed with the department (see note 5, supra).
The mother, on the other hand, bases her claim solely on the contention that the department is biased. She has made no showing that disclosure of the identity of the prospective adoptive family would be of assistance in defending any allegation that she is an unfit parent. Nor has she shown that disclosure would be relevant on the issue whether dispensing with consent would be in the best interests of the child. We believe that counsel can demonstrate bias, prejudice, and any shortcomings in the presentation of the petition to the judge without the disclosure of the identity of the prospective adoptive family. 17
Finally, “where a child’s well-being is placed in issue, ‘it is not the rights of parents that are chiefly to be considered.
*717
The first and paramount duty is to consult the welfare of the child.’”
Custody of a Minor,
The case is remanded to the Probate Court for further proceedings consistent with this opinion.
So ordered.
Notes
The natural father has executed, and the department has accepted, a written surrender for adoption. See G. L. c. 210, § 2 (procedure for giving written consent for adoption).
Counsel for the child agrees that the identity of the prospective adoptive family should not be disclosed to the mother.
The judge took no action on the mother’s motion to dismiss.
The single justice of the Appeals Court determined that the identity of a particular set of prospective adoptive parents was not relevant to any issue in proceedings conducted pursuant to a petition brought under G. L. c. 210, §3 (b). Additionally, the single justice concluded that in the particular circumstances of this case the potential harm to the child which would result from disclosure of the identity of the prospective adoptive family would outweigh any relevance of such disclosure.
Since we have concluded that the identity of the prospective adoptive family should be withheld from the mother, we have not set forth the precise questions reserved and reported as they tend to identify the adoptive family.

a final approval of the department’s adoption plans.
Petition of the Dep’t of Pub. Welfare to Dispense with Consent to Adoption,
The mother cites no authority to support her conclusion that the department’s conduct was illegal, except the State Conflict of Interest Law, G. L. c. 268A, §3 (b). On the limited record before us the statute does not appear to be applicable. At a minimum, we do not think that the Legislature intended the word “anything” in the statute to include children, or that the department acted other than in the proper discharge of its official duty.
As we read the record, the child was placed with an authorized foster care family after a judicial hearing. At the hearing, the mother was entitled to notice, G. L. c. 119, § 24; the appointment of counsel, G. L. c. 119, § 29; and notice of a right to appeal, G. L. c. 119, § 27. Nothing in the record indicates whether the mother appealed the original award of temporary custody. If the mother did not appeal, she is precluded from collaterally attacking those proceedings in the termination hearing. “The issue raised in the [temporary custody] action was actually litigated in the earlier proceeding and was essential to the earlier judgment. Therefore, the doctrine of issue preclusion bars relitigation of that issue in the subsequent action between the same parties.”

However, “when the breakup of a family is threatened ... an extra measure of evidentiary protection [is warranted].”
Custody of a Minor, (No. 1),
Since 1978 the department has had a regulation concerning placement of foster children with department employees. 106 Code Mass. Regs. § 288.031 (1978). This regulation provides: “All applications from Department personnel to become foster parents shall be referred to a private agency for evaluation. The decision of the private agency shall be final. ... No child in a worker’s and/or supervisor’s caseload shall be placed in the worker’s and/or supervisor’s home. Whenever possible a child who is being placed with a Department employee should be from a *713 different CSA [Community Service Area] than the one in which the employee works.”
The department claims that its evidence is largely documentary and not subject to a claim of bias. The department alleges, among other things, that the mother was tried in the State of Florida on the charge of having murdered her father, and that she was found not guilty by reason of insanity. The department claims that documents show that the mother was not responding to treatment and made no major improvements in her condition; and that she was released from Florida State Hospital despite the opinion of doctors that she was capable of violent behavior. An independent agency can determine whether the documents support the department’s allegations.
The mother also claims that she has a constitutional right to confront adverse witnesses,
Pointer
v.
Texas,
It is significant to note that the 1972 amendment deleted the exception which read “except by the adopting parent or parents, the child or person adopted, their attorney of record, the persons appearing in opposition to such petition or their attorneys of record.” G. L. c. 210, § 5C (as in effect until 1972), following the words, “shall not be available for inspection.”
General Laws c. 210, § 6, requires that a statement containing the names and addresses of prospective adoptive parents be filed before the court may issue a decree of adoption. Under § 5C, this statement is a confidential record.
Contrary to the mother’s view here that such information cannot be withheld in an adversary proceeding, confidential information is often protected. Indeed, the order of the single justice of the Appeals Court does not differ materially from a protective order under Mass. R. Civ. P. 26 (c),
In civil cases, confidential information often has been protected from disclosure by the courts. See, e.g.,
Keyes
v.
Lenoir Rhyne College,
The opportunity to cross-examine the witnesses from the department who testify, if any, is sufficient to show possible bias and conflicts of interest. However, the judge should exercise control of the cross-examination so that the identity of the prospective parent, or the employee’s exact position within the department, remains confidential. “Without derogating from the importance to a fair trial of the right to cross-examination . . . the courts of this Commonwealth have recognized that this right is not necessarily infringed by curbing inquiry where the matters sought to be elicited have been sufficiently brought to the attention of the trier of fact through other questioning or other means” (citations omitted).
