OPINION
MATTHEWS, Justice.On March 9, 1978, B.J.B.A., the natural mother of M.R.B., flew to Anchorage with her child from their home in the state of Washington to place the child for adoption with M.J.B. and F.G.B. Upon her arrival, the natural mother was transported to the office of the attorney for the adoptive parents where, unaccompanied by counsel, she signed a consent to adoption and waiver of notice form. She then returned to Washington that same afternoon.
On May 23, 1978, the natural mother unsuccessfully attempted to noúfy the adoptive parents by telephone of her intention to withdraw her consent to the adoption. On May 24, a hearing was held before the probate master on the appellees’ petition for adoption. The master indicated that *654she would wait until at least June 2 before closing the proceedings to allow for filing of an adoption investigation report pursuant to AS 20.15.100.1
On May 27, the natural mother notified the master by wire of her desire to withdraw her consent.2 On May 30, the probate master notified the natural mother that, based on the March 9 consent, “there appears to be no reason to prevent entry of a decree” of adoption, but that an appeal from the decree could be taken. On June 5, before filing of the investigation report and without finding a waiver of the report to be in the best interest of the minor child,3 the master recommended that the petition be granted. On the same day the superior court, relying on the probate master’s recommendation, but unaware of the natural mother’s attempted withdrawal of consent, signed and entered the decree of adoption. The adoption investigation report was filed with the court on June 12.
On June 15, the natural mother moved for relief from the decree, a new trial, and interim visitation rights. This motion was denied, after various delays,4 on October 10, 1979, and this appeal followed.
The issues here involve construction of AS 20.15.070, which provides:
Withdrawal of Consent, a) A consent to adoption may not be withdrawn after the entry of a decree of adoption.
b) A consent to adoption may be withdrawn before the entry of a decree of adoption, within 10 days, by delivering written notice to the person obtaining the consent, or after the 10 day period, if the court finds, after notice and opportunity to be heard is afforded to petitioner, the person seeking the withdrawal, and the agency placing a child for adoption, that the withdrawal is in the best interest of the person to be adopted and the court orders the withdrawal. .
The natural mother contends that her consent was invalid because the consent to adoption form did not include a statement of her right to withdraw the consent within ten days. She argues that such a statement was either required by statute, or, alternatively, the failure of the statute to include such a requirement has deprived her of due *655process of law. Second, she argues that AS 20.15.070(b) required the superior court to grant a hearing on whether she could withdraw her consent.
The natural mother’s first point is based on a reference to the statutory provision governing relinquishment of parental rights which states that a relinquishment is invalid unless it includes a statement of the ten-day right of withdrawal.5 The requirement of that provision, however, is not applicable to a consent to adoption. We agree that it might be beneficial to include such a requirement in AS 20.15.070, but that action is appropriate for consideration by the legislature rather than this court. As the Oregon Supreme Court stated in response to a challenge to its consent revocation statute, which bars the natural parents from revoking consent upon entry of a decree at the expiration of six months:
Since the legislature has enacted statutes prescribing how adoptions shall be accomplished, this court has no power to change in any particular the law as expressed in those statutes.... The role of this court is limited to construing the adoption statutes and attempting to ascertain the meaning of the legislature as expressed therein.
Strobel v. Garrison, 255 Or. 16, 464 P.2d 688, 689-90 (1970).
The natural mother argues in the alternative that if notice of the statutory right to withdraw one’s consent to adoption within ten days after it is given is not required by AS 20.15.070(b), then that statute has violated her right to due process of law. No persuasive authority is submitted to support this argument. We have recognized, in several different contexts, that a valid consent may be given without the person whose consent is requested first being advised of his or her statutory or constitutional right to refuse. A driver’s right to refuse consent to a breathalyzer test is one example. In Wirz v. State, 577 P.2d 227 (Alaska 1978), we held that in the absence of a specific statutory requirement that ar-restees be advised of their right to refuse the test, “it would be inappropriate for this court to engraft such a requirement onto [the statute].” 577 P.2d at 230. Similarly, the constitutional right to withhold consent to a police search need not be expressly communicated. Schneckloth v. Bustamonte, 412 U.S. 218, 93 S.Ct. 2041, 36 L.Ed.2d 854 (1973); Frink v. State, 597 P.2d 154 (Alaska 1979); Henry v. State, 621 P.2d 1 (Alaska 1980). We find these authorities persuasive and decline to hold AS 20.15.070 (b) to be unconstitutional as it stands.
The natural mother’s second point, however, is well taken. AS 20.15.070(b) provides, in addition to the absolute right of withdrawal within ten days, that one may withdraw one’s consent to adoption at any time before the entry of the adoption decree if the court finds, after notice and an opportunity to be heard is afforded to all parties involved, that the withdrawal is in the best interest of the person to be adopted. No statement of reasons for the desired withdrawal is called for. The statute clearly calls for a hearing on the best interest of the child if written notice of withdrawal is filed at any time prior to entry of the decree of adoption. Since such a notice was filed, the court’s failure to afford the natural mother a hearing was error.
*656In summary, we hold that the natural mother is entitled to a hearing to determine whether withdrawal of her consent is in the best interest of the child.6 We remand for such a hearing and set aside the decree of adoption pending its outcome. Since the consent is valid unless and until the court orders its withdrawal pursuant to AS 20.-15.070(b), the adoptive parents shall maintain interim custody. Should the court find withdrawal not in the best interest of the child, the decree may be reinstated nunc pro tunc.
VACATED and REMANDED.
BOOCHEVER, J., not participating.. AS 20.15.100 provides in part:
(d) Except as provided in (g) and (i) of this section, an investigation shall be made by the department or any other qualified agency or person designated by the court to inquire into the conditions and antecedents of a minor sought to be adopted and of the petitioner for the purpose of ascertaining whether the adoptive home is a suitable home for the minor and whether the proposed adoption is in the best interest of the minor.
(e) A written report of the investigation shall be filed with the court by the investigator before the petition is heard so long as the report is filed within 30 days of the designation by the court of the department, agency or person to make the investigation.
(f) The report of the investigation shall contain an evaluation of the placement with a recommendation as to the granting of the petition for adoption and any other information the court requires regarding the petitioner or the minor.
. The court was also notified of the withdrawal by counsel on May 30, 1975.
. AS 20.15.100(g) provides:
(g) Unless directed by the court, an investigation and report is not required in cases in which an agency is a party or joins in the petition for adoption, a step-parent is the petitioner, the person to be adopted is within the fourth degree of lineal or collateral consanguinity to the petitioner, or the person to be adopted is an adult. In other cases, the court may waive the investigation only if it appears that the waiver is in the best interest of the minor and that the adoptive home and the minor are suited to each other. The department which is required to consent to the adoption may give consent without making the investigation.
.Part of the delay was occasioned by the adoptive parents’ challenge to the natural mother’s eligibility for representation by Alaska Legal Services Corporation. “[T]he determination of ‘eligibility’ is an administrative decision within the scope of decision of the corporation and its recipients.” Martens v. Hall, 444 F.Supp. 34, 35 (S.D.Fla.1977). See generally, Dimmick v. Watts, 490 P.2d 483 (Alaska 1971). Although Alaska Legal Services does not have unlimited discretion in determining whether to accept clients, we can see no interests other than vexatious ones that were promoted by counsel for the adoptive parents in challenging such a determination. See Public Defender Agency v. Superior Court, 534 P.2d 947, 952 n. 7 (Alaska 1975).
. AS 20.15.180(b)( 1) provides:
b) All rights of a parent with reference to a child, including the right to receive notice of a hearing on a petition for adoption, may be relinquished and the relationship of parent and child terminated by a writing, signed by the parent, regardless of the age of the parent, a copy of which shall be given to the parent,
1) in the presence of a representative of an agency taking custody of the child, whether the agency is within or outside of the state or in the presence and with the approval of a court within or outside of this state in which the minor was present or in which the parent resided at the time it was signed, which relinquishment may be withdrawn within 10 days after it is signed or the child is bom, whichever is later; and the relinquishment is invalid unless it states that the parent has this right of withdrawal;
. As one factor in this determination the court should consider the circumstances as they were in May of 1978 when withdrawal of this consent was attempted. Of course, present circumstances must also be weighed.
