JAMES, P. J.

Defendant appeals from an order revoking probation and imposing a sentence, raising two assignments of error. We reject his second without discussion and write only to address his first. There, he argues that the trial court erred in accepting defense counsel's representations that defendant was willing to admit to three of the four allegations that he violated the conditions of probation. On appeal, defendant raises a plain-error argument that a trial court is required, in the context of a probation revocation hearing, to engage in a colloquy with defendant about the opportunity to contest the allegations and the rights he would be giving up by admitting the allegations. According to defendant, a failure to engage in such a colloquy is reversible error. We affirm.

Defendant is not entirely precise as to the source of law that underlies his argument. He references a 2005 Oregon Criminal Law Bench Book, which states that the court "should" make three determinations on the record: that the defendant knowingly is admitting the violation, that the admission is voluntary, and that the defendant understands the consequences of his or her admission. Defendant does not claim, quite properly, that bench books are authority. That portion of the bench book references federal caselaw, and as such, we understand defendant to be reasoning largely from federal due process.

Defendant notes that probation violation hearings carry many of the procedural safeguards of trials—such as a right to counsel and confrontation. Defendant argues that "[t]he requirement of a knowing and voluntary waiver of a probation violation hearing makes sense given that a waiver of the right to a jury trial must be knowing, voluntary, and in writing." We agree, and no party appears to dispute, that the waiver of a probation violation hearing must be knowingly and intelligently made. The question here, however, is whether a formal colloquy is required as evidence of that knowing waiver, or whether the representations of counsel are sufficient.

Defendant's argument that due process requires a formal colloquy has been rejected by the Ninth Circuit, which has held that a colloquy to ensure a knowing and intelligent waiver in the context of a probation revocation hearing is not required:

"Segal would have us extend the Boykin protections so that the record would show a voluntary and intelligent waiver of the rights she forfeited by admitting violation of the terms of her probation. But the Boykin rule is tailored to the defendant's entering a plea of guilty. It will not fit on a different mannequin. The Court in Boykin required an affirmative showing on the record that a plea of guilty was knowing and voluntary because the plea is itself a conviction, ending the controversy. But admissions of probation violations do not end the controversy. The judge must still decide the more difficult issue whether the violations warrant revocation of probation. This involves predictive and discretionary considerations in addition to factual inquiries. Moreover, the probationer is allowed to present evidence in mitigation of the violations. Thus, admissions of probation violations, unlike guilty pleas, do not automatically trigger sentencing. To the extent that admissions are viewed as immediately preceding sentencing, it is only because a prior guilty plea has led to suspending the imposition of sentence."

United States v. Segal , 549 F.2d 1293, 1298 (9th Cir), cert. den. , 431 U.S. 919, 97 S.Ct. 2187, 53 L.Ed.2d 231 (1977) (citations omitted). Although we are not bound by the Ninth Circuit on this issue, here we find its reasoning persuasive and reach the same conclusion. Any error was not plain.

Affirmed.
