delivered the opinion of the court.
On Mаy 6, 1966 James Paul Gogley, Jr., filed in the court below a petition for a writ of habeas corpus attacking the validity of two judgments entered against him by that court on Seрtember 18, 1962, one convicting him of robbery and the other of grand larceny, and sentencing him to confinement in the State Penitentiary for a term of. ten years on thе robbery charge and two years on the larceny charge, the sentences to run consecutively. He alleged that both judgments were void because at the time of his trial and conviction he was sixteen years of age, that no guardian ad litem was appointed to represent him at his trial in the juvenile court, аnd that he was denied the effec *680 tive assistance of counsel at the subsequent trial in the Corporation Court of the City of Norfolk, Part Two.
After the respondent Superintendent of the State Penitentiary had filed a general denial there was an ore tenus hearing, at the conclusion of which the lower court entеred an order denying the writ and dismissing the petition. Counsel was appointed by the lower court to prosecute this appeal from that order.
The record shows that on or about July 1, 1962 the petitioner was taken into custody by Norfolk police officers and held as a runaway from the State of Ohio. He escaped with another prisoner on July 4, and some two weeks later they were apprehended in New Jersey and returned to Norfolk.
On July 17, 1962 there was a hearing in the Juvenile and Domestic Relations Court of the City of Norfolk on the charges against the petitioner. At this hearing the petitioner was not represented by counsel, his parents were not present, and no guardian ad litem was appointed for him. As a result of this hearing the charges against the petitioner were certified tо the grand jury which shortly thereafter indicted him for robbery and grand larceny. Counsel was appointed by the lower court to represent him. Upon a plea оf not guilty to the charge of robbery and a plea of guilty to the charge of larceny, the petitioner, by consent, was tried by the court without a jury which entered the judgments complained of.
Upon consideration of the evidence in the habeas corpus proceeding the lower court held that the petitioner had not sustained the charge of ineffective assistance of counsel. We find that the evidence on that phase of the case, which the court has accepted as true, amply supports this holding.
The lower court also held that no guardian ad litem had been appointed to proteсt the interests of the petitioner in the juvenile court, as is required by Code § 16.1-173 [Repl. Vol. I960]. But it further held that while the requirement for the appointment of such a guardian ad litem is mandatory and jurisdictional under our holding in
Peyton
v.
French,
*681
In concluding that the decision in the
French
case should not be applied retrospectively, the lower court relied upon
Linkletter
v.
Walker,
In
Linkletter
the Supreme Court held that the exclusion of illegal evidence under
Mapp
v.
Ohio,
In our view the holdings in those cases relied on by the lower court are not applicable to the present case. Those cases dealt with what is characterized in
Johnson
v.
State of New Jersey, supra,
as “constitutional rules of criminal procedure laid down in recent years.”
Stovall
v.
Denno,
The obvious purpose “to be served by the new standards,” in the cases with which the Supreme Court was concerned, was to promote a full and fair hearing of the charges against a defendant. While the purpose of the holding in French was to protect the interests of a juvenile by the appointment of а guardian ad litem to represent him, there could have been no full and fair hearing of charges against him in a court of record if that court was without jurisdiction оf the proceeding. For jurisdiction of the person and the proceeding is the very basis of a full and fair hearing at a criminal trial.
Again, one of the prescribed criteria is “the extent of the reliance by law enforcement authorities on the old standards.” We are aware of no reliance on any standаrds which would justify the failure of a court to comply with the mandatory requirement for the appointment of a guardian ad litem in a proceeding against an infаnt in a juvenile court. On the contrary, it has long been the law in this State that an adverse ruling against an infant is void without the required appointment of a guardian ad litem to protect his interests. 9 Mich. Jur. Infants § 29, p. 738.
Finally, the effect on the administration of justice of a retroactive application to the present casе of the principles announced in French is entirely speculative. There is an entire lack of information as to the number of defendants whose convictions may be voided for the failure to appoint a guardian ad litem for them in a juvenile hearing. In this situation, we cannot say that the number of required new trials will disrupt the ordеrly administration of justice. Thus the application of this formula throws no light on the question presented to us here.
In our opinion, the lower court erred in holding that the principles announced in the French case should not be applied retrospectively to the hearing of the charges against the petitioner in the juvеnile court on July 12, 1962. For the reasons stated in that case, the failure of the juvenile court to appoint a guardian ad litem to protect the interests of the petitioner rendered the subsequent proceeding and his conviction in the criminal court void. Accordingly, the petition for a writ of habeas corрus should have been granted.
*683
Since the petitioner has now reached his majority and cannot be retried as a juvenile, he should be tried on new indictments if the Cоmmonwealth desires to proceed further against him.
