OPINION
delivered the opinion of the Court,
This case requires the Court to decide issues of federal constitutional law. Therefore, we are obligated to follow controlling United States Supreme Court federal constitutional precedents.
Appellee was indicted on one count of deadly conduct and three counts of at
*821
tempted murder. The trial court granted appellee’s motion to dismiss the indictment based on federal constitutional speedy trial grounds and the State appealed. Relying on its prior decision in
Melendez v. State,
the Court of Appeals affirmed the trial court’s decision.
State v. Munoz,
SUBSTANTIVE LAW AND APPELLATE STANDARD OF REVIEW
The essential ingredient of the Sixth Amendment’s speedy trial guarantee is “orderly expedition and not mere speed.”
United States v. Marion,
In reviewing the trial court’s decision on appellee’s federal constitutional speedy trial claim, the Court of Appeals applied a “bifurcated standard of review” meaning “an abuse of discretion standard for the factual components” and a
“de novo
” standard for the legal components of the trial court’s decision.
Munoz,
Most of the facts relevant to appellee’s speedy trial claim are undisputed. The issue here mostly involves the legal significance of these facts to this claim. Because appellee won in the trial court on his speedy trial claim, we must presume the trial court resolved any disputed fact issues in appellee’s favor, and we are required to defer to these implied findings of fact that the record supports. See
Guzman,
LENGTH OF DELAY
The length of delay is a “triggering mechanism” for analysis of the other
Barker
factors.
Barker,
This
Barker
factor “is actually a double enquiry.”
Doggett,
“Simply to trigger a speedy trial analysis, an accused must allege that the interval between accusation and trial has crossed the threshold dividing ordinary from ‘presumptively prejudicial’ delay, (citation omitted), since, by definition, he cannot complain that the government has denied him a ‘speedy’ trial if it has, in fact, prosecuted his case with customary promptness. If the accused makes this showing, the court must then consider, as one factor among several, the extent to which the delay stretches beyond the bare minimum needed to trigger judicial examination of the claim.” Id.
In this case, the State concedes and the Court of Appeals decided “a seventeen-month delay between the date of [appellee’s] arrest, February 11,1995, and the date of his speedy trial hearing, July 25, 1996, is sufficient to trigger review of the remaining
[Barker
] factors.”
Munoz,
REASON FOR THE DELAY
Under
Barker
“different weights should be assigned to different reasons” for the delay.
Barker,
During the hearing on appellee’s motion to dismiss the indictment based on speedy trial grounds, the prosecution attributed the entire seventeen-month delay to an overcrowded court docket and ongoing plea negotiations. The record reflects the prosecution made four plea offers to appel-lee during this period of time. Each succeeding plea offer was more beneficial to appellee than the previous plea offer.
“Q. Okay. And then would you agree that if that was in November, then in January, or at a later time, the negotiations came to the point where it was eight years in prison with no affirmative finding. Do you recall that made to you?
“A. [APPELLEE’S LAWYER] I recall the longer my client was in jail the lower and lower the recommendations were being made, to the final point of after he had been in jail to 17, almost 18 months now, that the recommendation was three years TDC with an affirmative finding, half time, which — which—although—al *823 though — which is often considered by many people time served. 2 ”
The parties agreed on a plea after the prosecution’s fourth plea offer. The case was set for a hearing on appellee’s plea for June 18, 1996. However, at the June 18th hearing appellee reneged on the deal and asked the prosecution for a more beneficial plea. The prosecution refused and informed the trial court there would be no guilty plea. The trial court set a trial date for August 19,1996.
“Q. Okay. And what was your — what was your offer in June of this year?
“A. In June of this year, that was the three years with the lesser offense on the affirmative finding and things of that nature.
“Q. Is it true, Mr. Thompson, in June of this year this case was set for a plea of guilty?
“A. That’s true. This case, I believe, was set twice in the month of June. I show that it was set June 18th for a plea of guilty. And I believe there was one prior setting — or earlier setting in June of this year where the case — where the . case was set.
“Q. Okay. What is your understanding of why the case was set for a plea of guilty?
“A, My understanding was that the defendant was going to plea (sic) guilty at that time.
“Q. Who did you get that understanding from?
“A. From the defendant’s attorney.
“Q. Is that Mr. Guerra?
“A. That is Mr. Guerra.
“Q. Can you tell the Court, Mr. Thompson, what happened when it was set for a plea of guilty in June of this year?
“A. My recollection is when it was set for a plea of guilty on June 18th of this year, that we went in to court. I had put together the evidence package, State’s Exhibit No. 2, tendered — given the defense counsel the stipulation and the waivers and all those things, and then — then while we were there in court, the defendant decided to reject — that he didn’t want three years, and Mr. Guerra came back to me and said, Give him two years. At that particular time, the judge then came out on the bench. It was announced that there wasn’t going to be a plea of guilty, that the defendant wanted a trial. And this case was then set for trial on the 19 th of August.”
The prosecution, appellee and appellee’s attorney all testified the entire seventeen-month delay was attributable to ongoing good faith plea negotiations. 3 The prose- *824 eution testified:
“Q. At this time could you expand on what the State’s excuse or reason for this defendant not being brought to trial is?
“A. Yes. This defendant — the State has been engaged in plea negotiations with this defendant’s attorney throughout the course of — of pendency of this particular case. We have gone through numerous plea offers, plea suggestions, continuous discussions with his Counsel as to how the case could be disposed of short of a trial, and in good faith, we have tried to negotiate the case in that manner. And so the case has not been brought to trial because the State at all times thought the case would not have to be brought to trial because the — the representations of defendant’s attorney was that — that plea negotiations were — were in good faith.”
Appellee testified:
“Q. Okay. And [appellee’s lawyer] has informed you that yes, I am trying to— to work out your case, negotiate — negotiate or work out a plea; is that correct? “A. Well, I guess so.
“Q. Okay. And this has happened during the whole — the whole time these charges have been pending; is that correct?
“A. Yes, sir.”
Appellee’s lawyer testified:
“Q. Okay. All right. And throughout this time, you have been negotiating in good faith with the District Attorney’s office on a plea in this particular case; is that correct?
“A. Yes.”
Appellee’s lawyer also testified the ease was going to be set “for trial” if “it wasn’t going to get worked out.”
“Q. Okay.
“A. I mean, if it wasn’t going to get worked out, we were going to set it for trial. And even if it was going to get worked out, it was going to be set for trial. I — it’s my understanding this case has been set for trial every month since he was arraigned, since he got his first trial setting on May 22 nd. That was my understanding.”
The Court of Appeals decided the State’s “excuse of plea negotiations” was an “unacceptable” excuse for the delay. See
Munoz,
We agree. Delay caused by good faith plea negotiations is not the result of negligence or a “deliberate attempt to delay the trial.” See
Barker,
We also note appellee was in large part responsible for the delay which is probably dispositive of appellee’s speedy trial claim. See
Barker,
ASSERTION OF FEDERAL CONSTITUTIONAL RIGHT TO SPEEDY TRIAL
Barker
rejected the “demand-waiver” rule which had held a defendant “forever” waives his right to a speedy trial when he does not demand one.
Barker,
The record reflects that on April 17, 1995, appellee signed a waiver of arraignment form which, among other things, contained a pro forma request for a trial date. The trial court set a trial date for May 22, 1995. However, as plea negotiations continued the case was passed monthly on the court’s docket with no objection from ap-pellee.
On August 17, 1995, appellee filed a motion to sever in which he requested that several of the counts in the indictment be severed into three separate jury trials. Appellee failed to obtain a ruling on his motion to sever and the record is silent on whether the trial court was ever aware of the motion.
When appellee declined to plead guilty at the June 18th plea hearing after having agreed to do so, the trial court set a trial date for August 19, 1996. On July 16, 1996, appellee filed a motion to dismiss the indictment in which he expressly complained for the first time about a violation of his right to a speedy trial.
After noting that “nothing [appellee] moved for or filed prior to his motion to dismiss the indictment of (sic) July 1996 expressly reflects an assertion of his right to a speedy trial,” the Court of Appeals nevertheless decided the “waiver of arraignment form” and appellee’s “motion to sever” requesting “three separate jury tri
*826
als” were an assertion of appellee’s right to a speedy trial.
Munoz,
We agree. As the Court of Appeals noted, “nothing [appellee] moved for or filed prior to his [July 1996] motion to dismiss the indictment expressly reflects an assertion of his right to a speedy trial.” See
Barker,
Appellee’s motion to sever and his
pro forma
request for a trial date in the waiver of arraignment form cannot be considered an assertion of his right to a speedy trial under the circumstances of this case. See
Barker,
PREJUDICE
The last
Barker
factor is “prejudice to the defendant.”
Barker,
This Court’s case law holds a defendant has the burden to make some showing of “prejudice” although a showing of “ ‘actual prejudice’” is not required.
Harris v. State,
The record reflects appellee was incarcerated in the county jail during the entire seventeen-month delay. During the hear
*827
ing on his motion to dismiss the indictment, appellee testified “he was scared and anxious, forgot many things that happened at the time of the incident that led to his arrest, lost his job, his family life was disrupted, he was forced into idleness, and he was uncertain as to the whereabouts of particular witnesses.”
Munoz,
“Q. Have you been in jail since you have been arrested?
“A. Yes, sir.
“Q. While in jail have you been scared?
“A. Uh-huh, yes.
“[THE COURT] You need to answer with words and loud enough so we can all hear.
“A. Yes, sir.
“Q. Have you been anxious?
“A. Yes, sir.
“Q. Have you wondered what is going to happen to you?
“A. Yes, sir.
“Q. Have you forgotten many of the details about what happened leading to your arrest?
“A. What?
“Q. Have you forgotten many things that have happened at the time of the incident that — that led to your arrest?
“A. Yes.
“Q. Okay. Your bond has been reduced two times but you can — your family cannot afford to get you out?
“A. Yes, sir.
“Q. Okay. Have you done anything to delay the trial of your case?
“A. No, sir.
“Q. Are you concerned you may not be able to locate some witnesses that would come to your defense because of this delay?
“A. If — I’m not going to—
“Q. Are — do you believe there are some witnesses you will not be able to find because of the delay that — 17 months and counting, that you have been in jail?
“A. Yes, sir.
“Q. Do you think some of the witnesses that you can find, including some of the neighbors, have forgotten a lot of the things that have happened?
“A. Yes, sir.”
On cross-examination, appellee testified he did not know if any witnesses were missing.
“Q. Okay. Is there anybody else, some particular person, that you — that you know has disappeared or that is no longer available to testify in this case?
“A Well, I don’t know where Sustaita is at or — or—or Zuniga. I don’t know. I don’t know.
“Q. Okay. But you are aware that your — your attorney hired an investigator to — to look into your case, correct? “A Yes, sir.
“Q. Okay. So you can’t tell me that those people are not around; is that correct?
“A. I don’t know if they are around or not.
“Q. Okay. You said you — you—you— that there were witnesses that were not around that have disappeared or are lost. Which witnesses are you referring to?
“[APPELLEE’S LAWYER] Your Hon- or, I’m going to object. That question has been asked and answered, asked and answered several times.
“[THE COURT] The objection is overruled. You may answer that question.
“A. Excuse me. What was the question again?
“Q. Can you — can you tell me a witness that is no longer available?
“A. Well, I just know — I don’t know if they are around.
“Q. You just don’t know?
“A. Yes.”
*828
The Court of Appeals decided “[a]nalysis of prejudice to the defendant is the most important of the
Barker
factors.”
Munoz,
“We regard none of the four factors identified above as either a necessary or sufficient condition to the finding of a deprivation of the right of speedy trial. Rather, they are related factors and must be considered together with such other circumstances as may be relevant. In sum, these factors have no talismanie qualities; courts must still engage in a difficult and sensitive balancing process-” Barker,407 U.S. at 533 ,92 S.Ct. at 2193 ,33 L.Ed.2d at 118 .
The Court of Appeals decided appellee made “some showing of prejudice” for three reasons.
Munoz,
As to the “oppressive pretrial incarceration” subfactor, the “dispositive consideration” is the impairment of a defendant’s liberty with its effects upon the defendant. See
Barker,
What is dispositive of “this consideration” is that appellee was incarcerated during the entire seventeen-month delay. As to the “anxiety and concern of the accused” subfactor, since appellee prevailed on his speedy trial claim in the trial
*829
court, we defer to the trial court’s implied findings that appellee “was scared and anxious beyond what would be expected from ordinary and inevitable pretrial incarceration.”
Munoz,
As to the “impairment of the defense” subfactor, the State argues the Court of Appeals’ decision that the prosecution failed to “meet its burden of contradicting” appellee’s “assertion of dimming memories” places “an impossible burden on the State.” 10 We understand the State to argue appellee’s bare “assertion of dimming memories” does not constitute “some showing” of an “impairment to the defense.”
We agree. Since appellee prevailed on his speedy trial claim in the trial court, we must defer to the trial court’s implied finding that the delay caused appellee “a memory loss in relation to details about the incident which led to his arrest.”
Munoz,
Barker
requires a defendant to show that “lapses of memory” are in some way “significant to the outcome” of the case. See
Barker,
In this case, appellee’s showing of prejudice was “minimal.” See
Barker,
BALANCING THE BARKER FACTORS
Comparing the facts of this case to
Barker’s
facts, it is easy to conclude the government did not violate appellee’s right to a speedy trial. See
Barker,
Having decided all issues fairly presented in the petitions for discretionary review and necessary to an intelligent resolution of appellee’s speedy trial claim, 12 we reverse the judgment of the Court of Appeals and remand the case to the trial court with instructions to reinstate the indictment.
Notes
. “Deliberate attempt to delay the trial” has been stated a number of ways.
Doggett,
. However, appellee complains on appeal as he did during the hearing on his motion to dismiss that this was unfair. Appellee claims the prosecution’s fourth plea offer was an attempt to coerce appellee to plea to “time served" which “unconstitutionally forced" ap-pellee “to make a decision to accept or not accept the plea offer.” See
Melendez,
A defendant can avoid this situation simply by demanding his right to a speedy trial. See
Barker,
. The Court of Appeals apparently ignored the undisputed evidence in the record that the
*824
entire
delay was attributable to the ongoing plea negotiations. See
Munoz,
. This Court of Appeals made a similar holding in
Melendez.
See
Melendez,
. This claim is presented in ground for review one of the State Prosecuting Attorney’s petition for discretionary review and ground for review three of the District Attorney’s petition for discretionary review.
. In
Barker
the Court stated there was “little difference” between Justice Brennan's analytical approach in
Dickey
and the analytical approach adopted in
Barker.
See
Barker,
. These claims are presented in ground for review two of the State Prosecuting Attorney’s petition for discretionary review and ground for review two of the District Attorney's petition for discretionary review.
. The Court of Appeals also decided appellee failed to make some showing of an impairment to his defense as a result of witness unavailability.
Munoz,
. In
Melendez,
the Court of Appeals apparently viewed a jury’s trial verdict sentencing the defendant to two years probation as having some bearing on this subfactor. See
Melendez,
. This claim is presented in ground for review four of the District Attorney’s petition for discretionary review.
. To the extent this Court’s case law might be inconsistent with
Barker
and other United States Supreme Court precedents such as
Doggett
and
Loud Hawk,
our case law would have to be overruled. See
