*685 OPINION
By the Court,
Appellant was seventeen years of age when he was charged, on March 3, 1966, with burglary, carrying a concealed weapon and the violation of curfew. Thereafter, while he was free on a return agreement, he was arrested on another charge of burglary.
When the appellant appeared in Juvenile Court, on March 31, 1966, with his parents, to answer a petition which had been filed March 14, 1966, he was not represented by counsel, nor was he advised that he had a right to be represented by an attorney. The record indicates that the purpose for the hearing was to consider the charges that had been lodged against the appellant and there is no indication that the question of certification within the provisions of NRS 62.080 1 was to be considered. However, after a brief statement 2 by the judge he was certified to be tried as an adult.
“A. February 3rd, next year.
“Court: You know as far as this department is concerned I think you’ve about run the route. I don’t know what we can do for you. I’m going to certify this boy as an adult. He will be remanded to the custody of the Las Vegas Police Department for further handling.”
*686 After being certified as an adult the appellant appeared in district court with counsel, and entered a plea of not guilty. A few days later he again appeared with counsel, withdrew his plea of not guilty, and entered a plea of guilty to the charge of burglary. Before allowing the appellant to withdraw his plea of not guilty the trial judge carefully questioned him about the voluntariness of his decision to change his plea from not guilty to guilty, and his understanding of the consequences of his act. The trial judge also determined that appellant’s counsel had fully discussed with him the nature of the charge and had explained to him his constitutional rights.
Although the trial judge did not specifically advise the appellant of the penalty, his counsel testified at the post-conviction hearing that he had advised the appellant of the consequences of his change of plea and the penalty which he could incur.
Sometime later, through different counsel, the appellant moved the trial court to reinstate his plea of not guilty. That motion was denied and the appeal from that denial was dismissed by this court.
On October 24, 1968, the appellant’s petition for post-conviction relief was denied, and from that order he appeals on the ground that he was denied due process of law because he was not afforded a full investigation and hearing at the time he was certified to be tried as an adult; that he was without the services of an attorney at the time of certification; and that the trial judge failed to advise him of the minimum and maximum sentence which could be imposed against him upon his plea of guilty.
The appellant relies on Kent v. United States,
While Kent was decided ten days before the appellant was certified, that case is not applicable because the United States Supreme Court declined to decide the Kent case on constitutional grounds, saying: “The Juvenile Court Act and the decisions of the United States Court of Appeals for the District of Columbia Circuit 3 provide an adequate basis for decision of this case, and we go no further.”
*687 Here, however, the juvenile court did not follow NRS 62.080, and therefore committed error when it certified the appellant without a full investigation, but this error was cured when the appellant, with the advice of competent counsel, plead guilty to the charge of burglary. •
It is now the established law of this state that where a guilty plea is not coerced and the defendant was competently represented by counsel at the time it was entered, the subsequent conviction is not open to collateral attack and any errors are superseded by the plea of guilty. Hall v. Warden,
In Rainsberger v. State,
* * * * *
“We hold that where, as here, one accused of murder voluntarily pleads guilty upon arraignment in open court, with the advice of competent counsel, the federal constitutional right to counsel is not violated, notwithstanding the fact that the accused, before entering his guilty plea, was without counsel when he confessed the crime and at the preliminary hearing.” Id. 100,
Now we must determine whether
Gault
is controlling in this case. We find that it is not, because the appellant’s certification hearing was held more than a year before
Gault
was decided. In Messmore v. Fogliani,
The United States Supreme Court in Stovall v. Denno,
The Supreme Court has given retroactive application to the constitutional right to the assistance of counsel where the lack of counsel affected “the very integrity of the fact-finding process” and there was present “the clear danger of convicting the innocent.” Gideon v. Wainwright,
In Messmore v. Fogliani, supra, we further stated: “As noted in Linkletter, if the constitutional principle is aimed at the fairness of the trial — the very integrity of the fact finding process — retrospective application is in order. Griffin v. Illinois,
Conversely, in Johnson v. New Jersey, supra, the Supreme Court held that the decisions in Escobedo v. Illinois,
When there is substantial doubt as to the reliability of a conviction the right to counsel has been applied retroactively. Here the appellant’s appearance in juvenile court did not result in a finding of his guilt of the crimes with which he was charged. The juvenile court judge only determined that he should be tried in the district court as an adult. He was not deprived of his right to present defenses to the charges in district court. Since there was no finding of guilt in the juvenile court, but only a certification, the fact that the appellant was not represented by counsel at the certification hearing did not affect the reliability of the guilt determining process as it did in Gideon v. Wainwright, supra; Hamilton v. Alabama, supra; and Douglas v. California, supra.
In Cradle v. Peyton,
In Johnson v. New Jersey, supra, the Supreme Court recognized the right of the New Jersey Supreme Court in a post-conviction proceeding to determine whether a new constitutional rule shall be applied retroactively or prospectively only. Here we apply the Gault decision prospectively only, from and after May 15, 1967.
In Gault the court said of its holding in the Kent case: “Although our decision turned upon the language of the statute, we emphasized the necessity that ‘the basic requirements *690 of due process and fairness’ be satisfied in such proceedings.” And that this and other cases unmistakably indicate that, whatever may be their precise impact, “[N]either the Fourteenth Amendment nor the Bill of Rights is for adults alone.” It is our view that Gault and Kent as interpreted in Gault “. . . [M]ean that the basic requirements of due process and fairness under the Fourteenth Amendment dictate that a juvenile is entitled to the assistance of retained or appointed counsel in a juvenile court hearing whether it results in a certification order or a commitment order because it is a ‘critical stage’ of the proceeding against him.” Cradle v. Peyton, supra at 886.
We find the appellant’s third contention to be without merit. Although the trial judge, who sentenced him upon his plea of guilty, did not advise him of the minimum and maximum sentence that could be imposed, he had the assistance of counsel, who at the post-conviction hearing, testified that he had advised the appellant of the possible sentence.
It is our further determination that Boykin v. Alabama,
The order of the district court denying the appellant’s petition for a writ of habeas corpus is affirmed.
Notes
NRS 62.080: “If a child 16 years of age or older is charged with an offense which would be a felony if committed by an adult, the court, after full investigation, may in its discretion retain jurisdiction or certify the child for proper criminal proceedings to any court which would have trial jurisdiction of such offense if committed by an adult; but no child under 16 years of age shall be so certified.”
