SEVERSON, Justice.
[¶ 1.] William Jensen was charged with fourth offense driving under the influence. He filed a motion to strike one of his three prior driving under the influence convictions. Jensen argued that because the magistrate court relied on a statement-of-rights form to establish the voluntariness of his guilty plea, that prior conviction is invalid for sentence-enhancement purposes. The trial court denied Jensen's motion to strike, concluding that the statement-of-rights form was an adequate record of voluntariness. We affirm.
[¶ 2.] On April 2, 2010, Rapid City Police Officer Eric Holmquist stopped Jensen at approximately 12:16 p.m. on suspicion of driving under the influence. When Officer Holmquist initiated contact with Jensen, he detected the odor of alcohol. Jensen denied drinking that morning but admitted that he drank a pint of whiskey the night before. When Jensen failed a field sobriety test, Officer Holmquist determined that Jensen had been driving under the influence and arrested him. A subsequent blood test revealed that Jensen's blood alcohol level was 0.267 percent.
[¶ 3.] In May 2010, a Pennington County grand jury indicted Jensen on alternative counts of driving under the influence.
[¶ 4.] Jensen pleaded guilty to a second offense driving under the influence charge in April 2006.
[¶ 5.] Before Jensen entered his guilty plea, the following colloquy took place:
The magistrate court then questioned Jensen to establish a factual basis. It concluded: "I'll also have the record reflect the Court has reviewed the reports submitted by [the arresting officer] and based upon that, your statements, I find a factual basis to support the plea and voluntary waiver of rights."
[¶ 6.] Jensen filed a motion to strike his prior 2006 conviction. Because the magistrate court relied on a statement-of-rights form to establish the voluntariness of his guilty plea, Jensen argues that the conviction is invalid for sentence-enhancement purposes. The trial court denied Jensen's motion to strike, concluding that the statement-of-rights form was an adequate record of the voluntariness of his plea. After a trial on stipulated facts in November 2010, the trial court found Jensen guilty of fourth offense driving under the influence and sentenced him to serve a term of four-years imprisonment in the state penitentiary. Jensen appeals.
[¶ 7.] Jensen argues that his prior driving under the influence conviction is invalid for sentence-enhancement purposes because the magistrate court relied on a statement-of-rights form to establish the voluntariness of his guilty plea. A conviction based on a plea that was not knowingly and voluntarily entered cannot be used to enhance a sentence under the habitual-offender statutes. Stuck v. Leapley, 473 N.W.2d 476, 477 (S.D.1991) (citing State v. King, 383 N.W.2d 854, 856 (S.D.1986); In re Application of Garritsen, 376 N.W.2d 575 (S.D.1985)). Jensen is not contending that he is innocent of the prior conviction but is instead seeking to deprive it of its normal force and effect for sentence-enhancement purposes. See State v. Moeller, 511 N.W.2d 803, 809 (S.D.1994).
[¶ 8.] Because Jensen challenges the validity of a prior conviction, this case is a collateral attack of a predicate conviction. See id. We have previously described the standard of review for collateral attacks:
State v. Goodwin, 2004 S.D. 75, ¶ 4, 681 N.W.2d 847, 849 (emphasis omitted) (quoting Moeller, 511 N.W.2d at 809).
[¶ 9.] We have also set forth a system of shifting burdens in a collateral attack of a predicate conviction. A "defendant has the initial burden of placing the validity of the prior conviction[ ] in issue." Stuck, 473 N.W.2d at 478 (relying on Dunn v. Simmons, 877 F.2d 1275 (6th Cir.1989); United States v. Dickens, 879 F.2d 410 (8th Cir.1989)). When a defendant raises the issue by a motion to strike or other appropriate means, the burden shifts to the State to prove "the existence of [a] prior valid conviction[ ] by a preponderance of the evidence." Id. at 478-79 (emphasis omitted) (citation omitted). The State meets this burden by presenting a document that "appears on its face to be a valid judgment." Moeller, 511 N.W.2d at 809. If the State meets its burden, the presumption of regularity arises and the burden shifts to the defendant to show that the prior conviction is invalid. Id. at 809-10 (citing State v. King, 400 N.W.2d 878, 879 (S.D.1987)). Because the State presented a document that appears to be a valid judgment of conviction, Jensen bears the burden of demonstrating that his 2006 conviction is invalid.
[¶ 10.] Jensen first argues that his prior conviction is invalid for sentence-enhancement purposes because the magistrate court did not follow the procedure set forth in SDCL chapter 23A-7 to establish the voluntariness of his guilty plea. SDCL 23A-7-5 describes the process to establish voluntariness:
SDCL 23A-7-15 further provides:
Jensen contends that his prior conviction is invalid because the magistrate court did not personally address him on the record, as chapter 23A-7 requires, to establish voluntariness.
[¶ 11.] Our review of a collateral attack of a predicate conviction is limited to jurisdictional errors. Monette v. Weber, 2009 S.D. 77, ¶ 6, 771 N.W.2d 920, 923 (quoting Owens v. Russell, 2007 S.D. 3, ¶ 6, 726 N.W.2d 610, 614-15). "In criminal cases, a violation of [a] defendant's constitutional rights constitutes a jurisdictional error." Id. (citation omitted). The United States Constitution does not mandate that courts follow the procedure embodied in chapter 23A-7. State v. Miller, 2006 S.D. 54, ¶ 17, 717 N.W.2d 614, 620 (citing McCarthy v. United States, 394 U.S. 459, 465, 89 S.Ct. 1166, 1170, 22 L.Ed.2d 418 (1969)). Rather, the procedure is a safeguard "designed to assist the courts with making the constitutionally[-]required determination that a defendant's guilty plea is voluntary and knowing, and to produce a complete record" of that determination. Id. (citation omitted). Because failure to follow the procedure is not a constitutional defect, a collateral attack on a predicate conviction on that basis is only proper for our consideration if a defendant can demonstrate prejudice. Brakeall v. Weber, 2003 S.D. 90, ¶ 11, 668 N.W.2d 79, 83 (citing United States v. Timmreck, 441 U.S. 780, 783-84, 99 S.Ct. 2085, 2087, 60 L.Ed.2d 634 (1979)).
[¶ 12.] Jensen has not argued that his guilty plea was involuntary. He only challenges the magistrate court's reliance on the statement-of-rights form to establish the voluntariness of his plea. Yet he indicated at his plea hearing that he read, signed, and understood the statement-of-rights form, which contained questions about voluntariness. On this record, Jensen did not demonstrate that the magistrate court's failure to personally canvass him to establish voluntariness made any difference in his decision to plead guilty. See id. Because Jensen has not demonstrated prejudice, his challenge to his prior driving under the influence conviction for failure to follow the procedure set forth in chapter 23A-7 is not proper for our consideration. See id.
[¶ 13.] Jensen next argues that his prior conviction is invalid for sentence-enhancement purposes because the magistrate court's reliance on the statement-of-rights form to establish the voluntariness of his guilty plea violated his due process rights. In Boykin v. Alabama, the United States Supreme Court recognized that a guilty plea is more than an admission of conduct; it is a conviction. 395 U.S. 238, 242, 89 S.Ct. 1709, 1711-12, 23 L.Ed.2d 274 (1969) (citing Kercheval v. United States, 274 U.S. 220, 223, 47 S.Ct. 582, 583, 71 L.Ed. 1009 (1927)). A defendant waives several important federal constitutional rights when he enters a guilty plea, including the right to remain silent, the right to a jury trial, and the right to confront witnesses. Id. at 243, 89 S.Ct. at 1712 (citations omitted). "We cannot presume a waiver of these . . . important federal rights from a silent record." Id. Therefore, "[t]he record must affirmatively show [that] the plea was voluntary, that the defendant understood the consequences of pleading guilty, and that the defendant explicitly waived" those rights. Monette, 2009 S.D. 77, ¶ 10, 771 N.W.2d at 925 (citation omitted).
[¶ 14.] We have stressed that a judge has a duty to personally canvass a defendant to establish the voluntariness of his guilty plea:
Goodwin, 2004 S.D. 75, ¶ 10, 681 N.W.2d at 852. The record must in some manner show that a defendant entered his plea intelligently and voluntarily. State v. Apple, 2008 S.D. 120, ¶ 10, 759 N.W.2d 283, 287 (citing State v. Beckley, 2007 S.D. 122, ¶ 10, 742 N.W.2d 841, 844).
[¶ 15.] We recently addressed whether a statement-of-rights form is an adequate record of the voluntariness of a defendant's guilty plea. In Monette, the sentencing court did not inquire whether Monette's no contest plea was coerced or influenced by threats or promises. 2009 S.D. 77, 771 N.W.2d 920. Although Monette signed a statement-of-rights form three days before the plea hearing, we did not believe that form alone was an adequate record of voluntariness:
Id. ¶ 15 n. 2. Because the sentencing court made no inquiry to determine whether Monette's plea was coerced, we ultimately held that the record failed to establish voluntariness. Id. ¶ 15.
[¶ 17.] Affirmed.
[¶ 18.] GILBERTSON, Chief Justice, and KONENKAMP and ZINTER, Justices, and MEIERHENRY, Retired Justice, concur.
The State argues that invalidating Jensen's prior conviction because the magistrate court did not personally address him to establish the voluntariness of his guilty plea would render this exception meaningless. We disagree. When a defendant is not present, SDCL 23A-7-5 requires that the magistrate court establish voluntariness by questioning the defendant's attorney.
