[¶ 1] Gеorge Gleeson appeals from a judgment of conviction entered upon a jury verdict finding him guilty of driving a motor vehicle while his driver’s license privilege was revoked. We affirm the judgment.
I
[¶ 2] George Gleeson’s driver’s license was revoked on October 8, 1998. On July 15, 1999, Gleesоn was arrested for driving a motor vehicle while his license privilege was revoked.
[¶ 3] Gleeson made an initial appearance before the trial court following his arrest. During his initial appearance, Gleeson appropriately answered questions regarding his address and his employment history and stated he understood the charge pending against him.
[¶ 4] The trial court scheduled a pretrial conference for September 13, 1999. Glee-son failed to appear at the pretrial conference apparently because he believed his attorney needed more time to prepare his defense. The pretrial conference was rescheduled for October 5, 1999, and Gleeson did appear. Gleeson expressed to the сourt that his attorney was inadequate and ineffective. As the pretrial conference progressed, however, Gleeson indicated to the court his court-appointed counsel could continue to represent him.
[¶ 5] Gleeson fired his attorney just bеfore trial. A jury trial was held on March 23, 1999. His attorney made the court aware of his dismissal before trial began. Shortly thereafter, Gleeson changed his mind and allowed his attorney to proceed in representing him.
[¶ 6] During trial, Gleeson did not dispute that he was driving a vehiclе while his license was revoked. Instead, he asserted an affirmative defense of lack of notice. He claimed the Department of Transportation (“DOT”) failed to give him notice of the order of suspension. Gleeson stated during his testimony, however, that hе had received notice of the suspension. His attorney asked Gleeson if he was confused, and Gleeson responded no. His attorney then asked Gleeson if there was anything more he wanted to add to his testimony, and Gleeson testified about the entire inсident in a long narrative. Gleeson testified that he never received notice of the DOT hearing revoking his license. The jury returned a guilty verdict on the offense. That same day, Gleeson filed his Notice of Appeal. At no time during or after the trial did either party or the court raise the issue of Gleeson’s competency.
II
[¶ 7] Gleeson contends the trial court erred in not conducting a competency hearing in order to determine if he was competent to stand trial. Gleeson concedes he did not requеst a competency hearing during trial. He argues, however, that based on his behavior and testimony throughout the proceedings, the trial court should have ordered a competency hearing sua sponte. We disagree.
[¶ 8] Before we will notice an error not brought to the attention of the trial court it must constitute an obvious error affecting the defendant’s substantial rights.
State v. Burke,
[¶ 9] It has long been held the conviction of a mentally incompetent accused is a violation of constitutional due process.
Dusky v. United States,
[¶ 10] Our case law states a competency hearing is required once evidence creating a “reasonable doubt” as to a defendant’s competency is raised.
State v. Storbakken,
[¶ 11] “A successful
Pate
challenge requires a showing that the trial [court] failed to see the need for a competency hearing when, based on the facts and. cirсumstances known to [the court] at the time, [it] should have seen such a need.”
Day,
[¶ 12] The United States Supreme Court in both
Pate
and
Drope
held specific factual circumstances gave rise to a sufficient doubt as to the defendants’ competency. In
Pate,
the defendant had béen convicted of murdering his wife without obvious explanation or motive.
[¶ 13] In the instant case, there is no similar evidence in the record which would have raised a sufficient doubt regarding Gleeson’s competence. Gleeson claims he was not able to assist his attorney in his own defense because he did not tell his attorney he had notice of the suspension order. Gleeson’s testimony at trial that he had notice of the suspension order came as a surprise to both his attorney and the court. The fact that Gleeson presentеd surprise testimony at trial, however, is not evidence in and of itself which establishes a sufficient doubt as to his competency to stand trial. Moreover, our Court has stated mental competency does not require the defendant to give perfectly cоnsistent testimony or to be a convincing liar.
State v. VanNatta,
[¶ 14] The fact that he did not understand his own defense is also of little significance. In September of 1998, Glee-son was arrested for driving under the influence of alcohol. Subsequently, the Department of Transportation administratively revoked his driver’s license. This case involves a collaterаl attack on the administrative determination made by the Department to suspend his driver’s license. At trial Gleeson contended his suspension was improper because he did not have notice of it. Gleeson, however, took the stand and testified that he had notice of the suspension, but he did not have notice of the hearing of the suspension. Apparently, Gleeson incorrectly believed his defense was based on his lack of notice concerning the hearing and not the suspension order. Because the DUI charge resulted in both administrative proceedings and court proceedings, Gleeson’s confusion is understandable. Confusion over
*863
these various proceedings and defenses attendant to each is common among lay people and wоuld not cause a trial court to have sufficient doubt as to Gleeson’s competency. Moreover, just because the defendant does not understand the proceedings unless they are explained to him or her in simple language does not establish the defendant is incompetent to stand trial.
Heger,
[¶ 15] After Gleeson acknowledged he had notice of the order of suspension, his defense attorney asked him if he had anything else to add to his testimony. Gleeson then testified about the entire incident in one long narrative. Gleeson claims that such testimony should have alerted the court as to his incompetency. A trial court, however, is not required to conduct a full blown hearing every time there is the slightest evidence of incompetency.
Storbakken,
[¶ 16] Gleeson’s final argument rests on his claim he lacked rapport with his attorney. During two pre-trial proceedings, Gleeson made certain statements regarding his attorney’s ineffectiveness while at other times he made certain statements praising his attorney. Prior to trial, he filed ethical complaints against the trial court, prosecutor, and his defense attorney. Gleeson, however, at the time of trial agrеed to have his attorney represent him, and a review of the record does not manifest he had an inability to assist his attorney in his defense. Mere evidence of complaints and dissatisfaction, without more, does not establish sufficient doubt as to defendant’s competency.
Ill
[¶ 17] We conclude based on our review of the record there were no facts or circumstances present before the trial court which should have created a sufficient doubt of the defendant’s competency so as to warrant a hearing on the issue. Accordingly, the judgment is affirmed.
Notes
. North Dakota Century Code § 12.1-04-06, provides: "Whenever there is reason to doubt the defendant's fitness to proceed, the court
may
order the detention of the defendant for the purpose of an examination by a psychiatrist or a licensed psychologist.” (Emphasis added.) The United States Supreme Court has clearly stated that a court
must sua sponte
conduct an inquiry into a defendant’s mental capacity if the evidence raises a sufficient doubt as to the defendant's competency at that time.
See generally Drope,
. The United States Court of Appeals for the Eighth Circuit, however, has noted that no single, descriptive phrase has emerged from the cases in our federal courts.
