{1} In this Opinion we review our speedy-trial jurisprudence and abolish the presumption that a defendant’s right to a speedy trial has been violated based solely on the threshold determination that the length of delay is “presumptively prejudicial.” Because Defendant has not shown any particularized prejudice that is cognizable under the constitutional right to a speedy trial and the weight of the other factors in the analysis do not overcome Defendant’s failure to show prejudice, we reverse the judgment of the Court of Appeals and affirm Defendant’s conviction and sentence.
{2} Though inapplicable in the present case, we also update our guidelines for determining the length of delay necessary to trigger the speedy trial inquiry to twelve months for simple eases, fifteen months for cases of intermediate complexity, and eighteen months for complex cases. We emphasize that these guidelines are merely thresholds that warrant further inquiry into a defendant’s claimed speedy trial violation and should not be construed as bright-line tests dispositive of the claim itself.
I. FACTS AND PROCEDURAL HISTORY
{3} Frank O. Garza (Defendant) was arrested late on June 28, 2006 for aggravated DWI and failure to maintain a traffic lane. The State filed a criminal complaint in magistrate court on June 29, 2006, and Defendant was released on the same day. The total amount of time Defendant spent in jail was two hours, from 2:35 a.m. to 4:24 a.m.
{4} The case remained in magistrate court, without apparent progress toward a trial, for four months. On November 2, 2006, the State refiled the charges in the Third Judicial District Court and the following day dismissed the ease without prejudice. Defendant made his first and only speedy trial demand on November 13, 2006 as part of his waiver of arraignment and plea of not guilty.
{5} In the Third Judicial District Court, the case initially was assigned to Judge Bridgforth, but the case was reassigned and the trial date set and reset several times. The case was reassigned to Judge Murphy on January 19, 2007 and trial was set for March 8, 2007. Judge Murphy recused himself on February 8, 2007 and the case was reassigned to Judge Driggers. The trial was reset for April 27, 2007 before Judge Driggers. That trial date was vacated because the case was reassigned, once again to Judge Bridgforth, on February 22, 2007. Finally, the trial was set for May 4, 2007 before Judge Bridgforth.
{6} Defendant filed a motion to dismiss on April 26, 2007, claiming that his right to a speedy trial had been violated. The district court denied the motion, finding, in pertinent part,
that a four month delay in Magistrate Court before removal to District Court weighs against the State. This is a simple case and the additional delay, even if it is sometimes the Courts’ own heavy trial docket, weighs slightly against the State. The case is now just past nine months which triggers the presumption of prejudice. Defendant has asserted his right to speedy trial. Defendant has suffered some actual prejudice in the form of restrictions imposed by pre-trial conditions of release and stress, but the Court feels this is not unusually great and weighs slightly against the State.
Defendant entered a conditional guilty plea on May 4, 2007 to aggravated DWI, contrary to NMSA 1978, Section 66-8-102(D)(l) (2005, prior to amendments through 2008), and failure to maintain a traffic lane, contrary to NMSA 1978, Section 66-7-317, reserving the right to appeal the district court’s denial of his motion to dismiss based on a violation of his constitutional right to a speedy trial.
{7} The Court of Appeals reversed the district court in a memorandum opinion, which held that the ten-month and six-day delay between Defendant’s arrest and the final trial setting, violated his constitutional right to a speedy trial. State v. Garza, No. 27,731, slip op. at 2 (N.M.Ct.App. Oct. 5, 2007). The Court’s opinion relied on the “presumption of prejudice” created by the delay, stating that “[e]ven though Defendant
{8} We granted the State’s petition for writ of certiorari, which raises one issue: whether the Court of Appeals erred by holding that Defendant’s right to a speedy trial was violated because the Court essentially applied a bright-line rule that nine months was the maximum length of delay permissible for a simple case. We also asked the Office of the Public Defender to file an amicus brief, addressing the issue of whether we should change the current guidelines for determining when the length of delay becomes “presumptively prejudicial,” and we permitted the State to respond to that issue. Because we conclude that our holding on this latter issue does not apply to the present case, we address it separately.
II. WHETHER THE COURT OF APPEALS ERRED BY HOLDING THAT DEFENDANT’S RIGHT TO A SPEEDY TRIAL WAS VIOLATED
{9} The State claims that the Court of Appeals erred in concluding that Defendant’s right to a speedy trial was violated by a ten-month and six-day delay. The State argues that “[t]he Court of Appeals’ analysis is most at fault in its treatment of prejudice and presumed prejudice,” because “[i]f a delay of one month over the presumptively prejudicial minimum—together with common bond restrictions—were sufficient, the Barker test would become essentially a bright-line rule.” We agree with the State that, in cases such as the present one in which all of the factors from Barker v. Wingo,
A. Purpose of the Speedy Trial Right
{10} The right to a speedy trial is a fundamental right of the accused. Barker,
In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence.
U.S. Const, amend. VI; see also N.M. Const, art. II, § 14. 1
{11} The speedy trial right, however, escapes precise definition. “The speedy-trial right is ‘amorphous,’ ‘slippery,’ and ‘necessarily relative.’ ” Vermont v. Britton, — U.S. -,
{12} Barker recognized that the right to a speedy trial is “generieally different from any of the other rights enshrined in the Constitution for the protection of the accused,” because there is a societal interest in bringing an accused to trial. Id. at 519,
[T]his constitutional guarantee has universally been thought essential to protect at least three basic demands of criminal justice in the Anglo-American legal system: (1) to prevent undue and oppressive incarceration prior to trial, (2) to minimize anxiety and concern accompanying public accusation and (3) to limit the possibilities that long delay will impair the ability of an accused to defend himself.
Smith v. Hooey,
{13} Violation of the speedy trial right is only determined through a review of the circumstances of a case, which may not be divorced from a consideration of the State and the defendant’s conduct and the harm to the defendant from the delay. Id. Accordingly, we have adopted the balancing test created by the United States Supreme Court in Barker, which delineates the following analytical framework for evaluating a claimed speedy trial violation:
In Barker, the United States Supreme Court created a balancing test, in which the conduct of both the prosecution and the defendant are weighed. The Court identified four factors: (1) the length of delay, (2) the reasons for the delay, (3) the defendant’s assertion of his right, and (4) the actual prejudice to the defendant that, on balance, determines whether a defendant’s right to a speedy trial has been violated.
State v. Maddox,
{14} In adopting the Barker analysis, this Court has similarly rejected bright-line analyses of the right to a speedy trial. Barker, however, was far from the model of clarity and has not provided a comprehensive analysis of this “slippery” right. Consequently, our courts have endeavored to adapt the Barker analysis to the unique factual circumstances presented in each ease. In the present case, we revisit certain aspects of the speedy trial right in light of Barker’s extensive progeny with a focus on the underlying purpose of Barker, to provide a functional analysis of the right to a speedy trial.
B. The Length of Delay: “Presumptively Prejudicial” Delay
{15} Barker is ambiguous as to what role the length of delay plays on the balancing
The length of the delay is to some extent a triggering mechanism. Until there is some delay which is presumptively prejudicial, there is no necessity for inquiry into the other factors that go into the balance. Nevertheless, because of the imprecision of the right to speedy trial, the length of delay that will provoke such an inquiry is necessarily dependent upon the peculiar circumstances of the case. To take but one example, the delay that can be tolerated for an ordinary street crime is considerably less than for a serious, complex conspiracy charge.
Id. at 530-31,
{16} With Barker’s limited guidance, our cases have attempted to decipher the function of “presumptively prejudicial” delay on the overall inquiry into whether a defendant’s right has been violated. In Zurla v. State, this Court held that a “presumptively prejudicial” length of delay creates an overall presumption that the defendant’s right to a speedy trial has been violated.
{17} Work v. State,
{18} Justices Baca and Wilson dissented from the Work plurality. Writing for the dissent, Justice Wilson argued that Zurla erroneously “carried forward” the presumption of prejudice. Work,
In my view, the better rule is to hold that the question of actual prejudice is a factor which must be determined on balance. If a defendant brings forth evidence of prejudice, the [S]tate will have the burden of rebutting such evidence. If no evidence of prejudice is offered, then the scales are balanced. In this latter situation the question of actual prejudice would be neither for nor against either party, but neutral.
Id.
{19} Salandre v. State,
“[p]resumptively prejudicial delay” refers to prejudice to the fundamental right to a speedy trial, not to specific prejudice covered by the fourth [Barker ] element, much less simply to impairment of the defense at trial.... [0]nee the defendant demonstrates existence of presumptively prejudicial delay, “the burden of persuasion rests with the [Sjtate to demonstrate that, on balance, the defendant’s speedy trial right was not violated.”
Id. at 427,
{20} While other courts and commentators have struggled with this issue, the overwhelming majority have rejected an interpretation of Barker that creates the kind of presumption that our cases have adopted. Uviller, supra, at 1384-85. (“Whether or not such a shift in the vital burden is wise, it seems clear that it is unintended by the Court. Rather, it is likely that the choice of the term ‘presumptively prejudicial’ in the duration discussion was simply inadvertent. Probably, the Court meant to say simply that a claim of denial of speedy trial may be heard after the passage of a period of time which is, pilma facie, unreasonable in the circumstances.”). Though Barker’s limited treatment of this issue leaves room for various interpretations, no federal circuit courts have adopted a rationale similar to ours, in which the determination of presumptive prejudice creates a presumption that the defendant’s right has been violated. See 5 LaFave et al., supra, § 18.2(b) (“The reference to ‘delay which is presumptively prejudicial’ contributes to this confusion, but viewing the case in its entirety it seems fair to say that this phrase does not mean a period of time so long that it may actually be presumed the defense at trial would be impaired. Nor does it mean that once a sufficient time has been shown the prosecution has the burden of establishing that in fact there was no prejudice.” (footnote omitted)). The Circuit Courts of Appeals uniformly treat the threshold inquiry of whether the delay is “presumptively prejudicial” as merely a triggering mechanism and do not carry forward any presumption based on this determination. See United States v. Harris,
{21} In Zurla, Work, and Salandre, we considered only Barker’s ambiguous language
{22} We, therefore, modify the standards set forth in Zurla, Work, and Salandre to the extent they are inconsistent with this holding. However, where the defendant proves actual prejudice, see infra Part II.E, the State retains its burden of persuasion on the ultimate question of whether the defendant’s right to a speedy trial has been violated.
{23} If a court determines that the length of delay is “presumptively prejudicial,” then it should consider the length of delay as one of four factors in the analysis, none of which alone are sufficient to find a violation of the right. Barker,
{24} Considering the length of delay as one of the four Barker factors, the greater the delay the more heavily it will potentially weigh against the State. The delay in this case scarcely crosses the “bare minimum needed to trigger judicial examination of the claim.” Doggett v. United States,
C. Reasons for the Delay
{25} “Closely related to length of delay is the reason the government assigns to justify the delay.” Barker,
{27} Finally, “a valid reason, such as a missing witness, should serve to justify appropriate delay.” Barker,
{28} The record reflects that the delay in the present case was negligent. The State asserts that the delay of four months in which this case sat in magistrate court before the State dismissed the charges and refiled in district court, were predicated on this Court’s opinion in State v. Reinsen,
{29} The remainder of the delay is attributable to the multiple reassignments of judges in the district court. This delay falls within the administrative burdens on the criminal justice system, such as overcrowded courts, Barker,
{30} Because the delay was negligent, the extent to which it weighs against the State depends on the length of the delay. As described above, the delay in this case extends only slightly beyond the threshold to trigger the speedy trial inquiry and, therefore, is not extraordinary. Accordingly, because the delay was negligent but not protracted, this factor weighs only slightly in Defendant’s favor.
D. Assertion of Defendant’s Right
{31} In Barker, the United States Supreme Court rejected “the rule that a defendant who fails to demand a speedy trial forever waives his right.” Barker,
{32} Generally, we assess the timing of the defendant’s assertion and the manner in which the right was asserted. Maddox,
{33} It is necessary, therefore, to closely analyze the circumstances of each ease. For example, a court should assign “different weight to a situation in which the defendant knowingly fails to object, from a situation in which his attorney acquiesces in long delay without adequately informing his client, or from a situation in which no counsel is appointed.” Barker,
{34} In the present ease, Defendant’s single demand for a speedy trial, preceding his motion to dismiss, tucked within the waiver of arraignment and not guilty plea, was sufficient to assert his right. This assertion was not especially vigorous nor was it mitigated, however, by any apparent acquiescence to the delay on Defendant’s part. Therefore, this factor weighs slightly in Defendant’s favor. See Maddox,
E. Prejudice to the Defendant
{35} “The United States Supreme Court has identified three interests under which we analyze prejudice to the defendant: (i) to prevent oppressive pretrial incarceration; (ii) to minimize anxiety and concern of the accused; and (iii) to limit the possibility that the defense will be impaired.” Id. ¶32 (internal quotation marks and citation omitted). As to the first two types of prejudice, “[s]ome degree of oppression and anxiety is inherent for ever[y] defendant who is jailed while awaiting trial.” Id. ¶ 33 (alterations in original) (internal quotation marks and citation omitted). Therefore, we weigh this factor in the defendant’s favor only where the pretrial incarceration or the anxiety suffered is undue. Id. The oppressive nature of the pretrial incarceration depends on the length of incarceration, whether the defendant obtained release prior to trial, and what prejudicial effects the defendant has shown as a result of the incarceration. Barker,
{36} The third type of prejudice is the “most serious.” Barker,
{37} Defendant, in the present case, spent two hours in jail and was then released with normal bond restrictions. We acknowledge that the district court found “some actual prejudice in the form of restrictions imposed by pre-trial conditions of release and stress.” However, “some [non-particularized] prejudice” is not the type of prejudice against which the speedy trial right protects. Therefore, we hold that Defendant has made no showing of prejudice that is cognizable under the fourth Barker factor.
F. Balancing Test
{38} The primary issue raised by the facts of this case is whether a court can find a violation of a defendant’s speedy trial right without a particularized showing of prejudice. The United States Supreme Court’s opinion in Doggett is instructive on this point. Doggett held that “affirmative proof of particularized prejudice is not essential to every speedy trial claim.” Doggett,
{39} Thus, Doggett seemed to adopt the position of many lower courts, which generally require that defendants make an affirmative showing of particularized prejudice but excuse that requirement and presume prejudice if the other Barker factors weigh heavily in the defendant’s favor. See, e.g., Mendoza,
{40} In the present ease, Defendant failed to show prejudice, and the other factors do not weigh heavily in Defendant’s favor. Because Defendant failed to demonstrate particularized prejudice as a consequence of the ten-month and six-day delay, we cannot conclude that Defendant’s right to a speedy trial was violated. Accordingly, we reverse the Court of Appeals.
III. CHANGE IN CURRENT GUIDELINES
{41} We asked the Public Defender’s office to file an amicus brief, and permitted the State to respond, addressing the issue of whether we should change the current guidelines — nine months for simple cases, twelve months for cases of intermediate complexity, and fifteen months for complex cases — concerning “presumptively prejudicial” length of delay. In light of our conclusion that Defendant’s right was not violated, we recognize that we need not address the guidelines for determining when the length of delay becomes presumptively prejudicial. However, we do so in the interest of providing guidance to the lower courts and to recognize recent changes in the administration of our criminal justice system.
{42} We have provided broad guidelines for determining when the length of delay triggers further inquiry into the claim of a violation of the right to speedy trial. Maddox,
{43} We implemented Rule 5-604(B) NMRA in response to Barker. “Rule 5-604(B), commonly referred to as the six-month
{44} Over time, the minimum length of delay considered “presumptively prejudicial” and the six-month rule have mirrored each other. This Court first held that a six-month delay is sufficient to trigger the Barker balancing test. State v. Mendoza,
{45} When Salandre was decided, Rule 5-604(B) required that cases be tried within six months but permitted extensions upon application to the Supreme Court. In 1998, we amended Rule 5-604 to permit the district court to grant a three-month extension before requiring parties to apply to this Court for an extension of time. Thus, the 1998 amendment reflected the conclusion in Salandre that for simple eases, nine months was the minimum length of delay considered presumptively prejudicial.
{46} On August 13, 2007, we amended Rule 5-604 by increasing the amount of time that the trial court may grant as an extension from three to six months before the parties must apply to this Court. That amendment demonstrates the need for greater flexibility in the trial courts to grant extensions due to greater inherent delays involved in the prosecution of criminal cases. With that amendment we no longer require application to this Court in which the party must explain the “extreme circumstances” necessitating an extension until the length of delay exceeds twelve months. In contrast, our speedy trial cases have continued to indicate that a nine-month delay may be presumptively prejudicial, resulting in the anomalous possibility that a defendant’s right to a speedy trial may be violated by delay that is otherwise reasonable. The lack of congruence between our speedy trial standard and Rule 5-604 fails the purpose of our guidelines, which is “to provide the courts and the parties with a rudimentary warning of when speedy trial problems may arise.” Salandre,
{47} We hold, therefore, that one year is the appropriate guideline for determining when the length of delay for a simple case may be considered presumptively prejudicial. This is consistent with the majority of other jurisdictions, both federal and state. The federal circuit courts are of a general consensus that delay of approximately one year may be considered presumptively prejudicial. See, e.g., United States v. Watford,
{48} Consistent with the 2007 amendment to Rule 5-604 and the consensus of our sister states and the federal Circuit Courts of Appeals, we adopt one year as a benchmark for determining when a simple case may become presumptively prejudicial. Accordingly, we also shift the guidelines for cases of greater complexity: Fifteen months may be presumptively prejudicial for intermediate cases and eighteen months may be presumptively prejudicial for complex cases.
{49} We emphasize that these guidelines should not be construed as bright line tests. Rather, they are meant to guide the district courts’ determination of “presumptively prejudicial” delay. The situation may arise where a defendant alerts the district court to the possibility of prejudice to his defense and the need for increased speed in bringing the ease to trial, i.e., the impending death of a key witness. Where that possibility is realized and the defendant suffers actual prejudice as a result of delay, these guidelines will not preclude the defendant from bringing a motion for a speedy trial violation though the delay may be less than one year. However, it will then be up to the district court to decide whether the delay was sufficient to require further inquiry into the speedy trial analysis.
{50} This shift in the applicable guidelines is predicated on the 2007 amendment to Rule 5-604, which became effective on August 13, 2007. This shift, therefore, was not foreshadowed prior to that date, and the district courts were not on notice that the old guidelines did not accurately represent the amount of delay that should trigger a speedy trial inquiry. Because these time thresholds are merely guidance to the district courts, where the courts have relied on the old guidelines prior to August 13, 2007, we will not apply the new guidelines to our review on appeal. Therefore, these guidelines apply only to speedy trial motions to dismiss initiated on or after August 13, 2007. Though it would make no difference in the ultimate result, we have not applied the new guidelines in the present case, because the district court heard and ruled on Defendant’s motion to dismiss on April 27, 2007.
IV. CONCLUSION
{51} For the above stated reasons, we reverse the judgment of the Court of Appeals and affirm Defendant’s conviction and sentence.
{52} IT IS SO ORDERED.
Notes
. Article II, Section 14 ol the New Mexico Constitution provides:
In all criminal prosecutions, the accused shall have the right to appear and defend himself in person, and by counsel; to demand the nature and cause of the accusation; to be confronted with the witnesses against him; to have the charge and testimony interpreted to him in a language that he understands; to have compulsory process to compel the attendanee of necessary witnesses in his behalf, and a speedy public trial by an impartial jury of the county or district in which the offense is alleged to have been committed.
We have not previously decided, and Defendant does not argue here, whether New Mexico's speedy trial guarantee should be interpreted differently than the Sixth Amendment. See State v. Maddox,
