*702Youth appeals from an amended judgment finding him within the jurisdiction of *439the juvenile court based on acts that, if committed by an adult, would constitute second-degree criminal mischief, ORS 164.354.
We agree with youth that the initial judgment finding him within the court's jurisdiction for acts constituting the lesser-included offense was an acquittal that barred a second adjudication on the original offense of second-degree criminal mischief. We therefore reverse the amended judgment and remand for entry of a dispositional judgment finding youth within the court's jurisdiction based on the lesser-included offense of third-degree criminal mischief.
*703The relevant facts are not in dispute. After an altercation involving youth, the state filed a petition to find him within the juvenile court's jurisdiction for acts that, if committed by an adult, would constitute second-degree criminal mischief, ORS 164.354.
Despite that expressed uncertainty, the juvenile court proceeded to reduce its spoken ruling to writing immediately following the trial, entering a judgment finding youth within its jurisdiction based on acts constituting the lesser-included offense. On the judgment form, the court checked a box continuing the matter to a later date for disposition "& motion."
At the subsequent hearing, the juvenile court decided that it had authority to change or amend the judgment, and it found youth *440within its jurisdiction for the originally charged act, that, if committed by an adult, would constitute second-degree criminal mischief. The juvenile court *704entered the amended judgment that is now on appeal, which includes a disposition based, in part, on the finding that youth committed acts that would constitute second-degree criminal mischief.
On appeal, youth assigns error to the juvenile court's decision to enter the amended judgment, arguing it violated his rights against double jeopardy under the Fifth Amendment to the United States Constitution and Article I, section 12, of the Oregon Constitution.
The basic principles are not in dispute. Youth and the state agree that, if the first judgment constituted an acquittal, it would preclude a second judgment on the same offense. U.S. Const., Amend. V ; Or. Const., Art. I, § 12 ; Evans v. Michigan ,
The parties recognize that a finding of responsibility for acts related to the lesser-included offense, third-degree criminal mischief, would effectively acquit youth of acts related to the greater offense, second-degree criminal mischief. United States v. DiFrancesco ,
Youth asserts, and we understand the state to concur, that an acquittal precludes retrial even when premised upon a mistake of law, such as the court misconstruing statutory requirements for conviction.
We reached that conclusion under analogous circumstances in State ex rel. Juv. Dept. v. Decoster ,
Although we have had no opportunity to directly address, for double jeopardy purposes, the finality of a juvenile court's initial judgment, the issue of finality commonly arises in civil cases in the context of claim preclusion, where claim preclusion was traditionally called res judicata . That doctrine, like the double jeopardy provisions, is fundamentally concerned with ensuring finality. See Crist v. Bretz ,
*707Green v. United States ,
In cases on claim preclusion, Oregon courts have determined that "[a] judge may change his mind concerning the proper disposition between the time of a hearing and his final action which takes place when he signs the order disposing of the matter." State v. Swain/Goldsmith ,
In this case, we conclude that the original judgment finding youth within the court's jurisdiction was final because the juvenile court committed it to writing and duly entered it as a judgment. Initially, the court made a spoken ruling, after which it was free to change its mind concerning the proper conclusion-until the time of the final action when the court signed and entered its decision on the matter.
Stressing the trial transcript, the state argues that the juvenile court intended, and youth understood, the *709initial judgment to be tentative and inconclusive. Although the court and parties may well have spoken with uncertainty about the accuracy or malleability of the court's initial determination, the signed judgment taking jurisdiction-not the statements from the judge, the state, or youth-governs our determination of what was decided. Swain/Goldsmith ,
We disagree with the state that Swisher v. Brady ,
In this case, the juvenile court entered a judgment finding youth within its jurisdiction for a lesser-included offense, based on a substantive issue whether the prosecution sufficiently proved the offense's required elements. That determination had the legal effect of acquitting youth of the greater offense, precluding further adjudication of it. DiFrancesco ,
*710We hold that, because the juvenile court entered a judgment finding youth within its jurisdiction for acts relating to the lesser-included offense, that judgment acquitted youth of acts relating to the greater offense. That acquittal precluded further adjudication of acts relating to the greater offense. See Decoster ,
Reversed and remanded.
ORS 164.354 provides, in part:
"(1) A person commits the crime of criminal mischief in the second degree if:
"(a) The person violates ORS 164.345, and as a result thereof, damages property in an amount exceeding $500; or
"(b) Having no right to do so nor reasonable ground to believe that the person has such right, the person intentionally damages property of another, or, the person recklessly damages property of another in an amount exceeding $500."
ORS 164.345 provides, in part:
"(1) A person commits the crime of criminal mischief in the third degree if, with intent to cause substantial inconvenience to the owner or to another person, and having no right to do so nor reasonable ground to believe that the person has such right, the person tampers or interferes with property of another."
The petition also charged youth with acts that, if committed by an adult, would constitute one count of attempted assault in the fourth degree, ORS 163.160, and two counts of harassment, ORS 166.065.
The document was labeled "JUDGMENT/ORDER FROM CONTESTED JURISDICTION HEARING." The state neither disputes that it was a judgment nor argues that the labels "judgment" or "order" matter for purposes of this case. See generally State ex rel. Juv. Dept. v. Tyree ,
In relevant part, the Fifth Amendment provides that no person shall "be subject for the same offence to be twice put in jeopardy of life or limb," and Article I, section 12, provides that "[n]o person shall be put in jeopardy twice for the same offence."
These protections extend to juvenile proceedings. Breed v. Jones ,
The state cites Evans for the proposition that "acquittal, however erroneous it was, precludes reprosecution on the charge." (Citation, internal quotation marks, and brackets omitted.) At the same time, the state began oral argument saying, "The question in this case is does the constitution prohibit the court from correcting [the] mistake." In its brief, the state warned against a decision wherein "a judge's slip of the tongue-no matter how quickly corrected-would constitute an acquittal." Given those statements, we understand the state to argue that, if youth had been acquitted, the acquittal would have barred future adjudication regardless of its erroneous foundation. The state only contends that the court could correct its mistake because no acquittal occurred.
We do not suggest that the "Double Jeopardy Clause is simply res judicata dressed in prison grey." LaFave et al. , 6 Criminal Procedure § 25.1(b) (4th ed. 2017) (citation and internal quotation marks omitted). Res judicata has some additional policy concerns regarding judicial efficiency and the costs of relitigation.
The state contends that we should reach a different conclusion, following State v. Sperry ,
"an oral ruling allowing a motion for judgment of acquittal is not preclusive, and may be rescinded, where, as here, neither the parties nor the court have detrimentally relied on that ruling * * * in the interval between the oral allowance and rescission."
