BROOKS
v.
The STATE.
No. A10A1077.
Court of Appeals of Georgia.
June 1, 2010.
*111 Jennifer B. Ventry, for Appellant.
Paul L. Howard Jr., Dist. Atty., Lenny I. Krick, Asst. Dist. Atty., for Appellee.
JOHNSON, Judge.
After a jury trial in June 2001, Anthony Brooks was convicted of battery, rape and false imprisonment. Brooks moved for a new trial, and on October 22, 2002, the trial court granted the motion due to ineffective assistance of trial counsel. On November 15, 2002, Brooks' lawyer filed a request for permission to file a speedy trial demand. On November 20, 2002, the lawyer withdrew and a new attorney was appointed to represent Brooks. On or about that same day, Brooks was released from confinement on bond. In August or September 2003, the case appeared on a trial calendar. However, the case did not proceed to trial, and several months later Brooks' attorney withdrew and another lawyer was appointed to represent him.
While out on bond, Brooks was twice arrested and charged with felony offenses unrelated to the original charges for which he was tried in 2001. In 2004, he was charged with and convicted of possession of cocaine. In 2007, he was indicted for aggravated battery, a case that is still pending. Also, several years after the motion for new trial was granted in the 2001 case, the original trial judge passed away, and the case was assigned to two different judges.
On September 30, 2009, Brooks filed a plea in bar and motion for discharge and acquittal, claiming a denial of his right to a speedy trial. The trial court denied the plea in bar and motion. Brooks appeals, contending that the trial court's ruling was erroneous because his constitutional right to a speedy trial was violated by the lapse of approximately seven years since his motion for a new trial was granted.
Brooks' constitutional speedy trial claim must be analyzed under the following *112 four-part balancing test established by Barker v. Wingo:[1]
(1) the length of the delay; (2) reasons for the delay; (3) defendant's assertion of the right [to speedy trial]; and (4) the prejudice to the defendant. Standing alone, none of these factors are a necessary, or sufficient condition to a finding of deprivation of the right to a speedy trial, but rather should be considered as part of a balancing test. Thus, we must apply and weigh these factors together to determine if [Brooks'] constitutional right to a speedy trial has been abridged.[2]
On appeal, a trial court's denial of a motion for discharge and acquittal based on an alleged speedy trial violation is reviewed under an abuse of discretion standard.[3]
(a) Length of delay: The initial inquiry is whether the length of the delay creates a presumption of prejudice.[4] As the state concedes, the approximate seven-year period between the grant of Brooks' motion for a new trial and the filing of the plea in bar and motion for discharge and acquittal is presumptively prejudicial.[5] Therefore, the other three Barker factors must be considered.[6]
(b) Reason for delay: This factor addresses the issue of
whether the government or the criminal defendant is more to blame for the delay. Deliberate delay to hamper the defense weighs heavily against the prosecution. More neutral reasons such as negligence or overcrowded courts weigh less heavily but nevertheless should be considered since the ultimate responsibility for such circumstances must rest with the government rather than with the defendant. In contrast, delay caused by the defense weighs against the defendant: If delay is attributable to the defendant, then his waiver may be given effect under standard waiver doctrine.... That rule accords with the reality that defendants may have incentives to employ delay as a defense tactic: delay may work to the accused's advantage because witnesses may become unavailable or their memories may fade over time.[7]
In this case, since Brooks filed his motion for a new trial, he has had at least four different attorneys. The attorney who represented him for most of that time, from 2003 to 2007, testified that he did not recall ever meeting with Brooks or the district attorney about the case, and that he did not do anything to move the case forward because "it was a sleeping dog and it wasit was laying like a sleeping dog." Thus, delay was clearly a defense tactic that must weigh against Brooks.[8]
However, the government also shares responsibility for the delay in the case. After the judge who presided over the first trial passed away, the case was assigned to various judges. "Such delay [from changing judge assignments] weighs minimally against the State."[9] Moreover, for a period between 2008 and 2009, the state could not locate its file on the case. But as Brooks acknowledges, there is no evidence that the state deliberately attempted to delay the trial. Rather, it appears that the state was simply negligent in pursuing the case. "Thus, although part of the delay may be attributed to the State's negligence, this factor must be weighed as a relatively benign consideration *113 against the State."[10] Having balanced the reasons for the delay attributable to both the state and the defense, we conclude that "this Barker factor ultimately remains neutral."[11]
(c) Assertion of right: Approximately a month after the trial court granted the motion for a new trial, Brooks filed a request for special permission to file a speedy trial demand pursuant to OCGA § 17-7-171(a). However, he did not obtain a ruling from the trial court on that request and has never filed a demand for speedy trial.[12] Indeed, he did not raise the issue again until he filed the plea in bar, nearly seven years after the motion for a new trial had been granted.
It is true that "`the filing of a speedy trial demand is not a prerequisite for a plea in bar for failure to have a speedy trial on constitutional grounds.' [Cit.]"[13] However, even though such a demand is not a prerequisite for a plea in bar on constitutional grounds, it is still "the defendant's responsibility to assert the right to trial, and the failure to exercise that right is entitled to strong evidentiary weight against the defendant [under the Barker analysis]."[14] Accordingly, in this case, the delay in asserting the right to a speedy trial must be weighed against Brooks because he "filed no statutory demand for speedy trial pursuant to OCGA § 17-7-171 and did not raise his constitutional right to a speedy trial for [almost seven years] between [the grant of a new trial] and the filing of his motion to dismiss, in which he finally asserted the right."[15]
(d) Prejudice to defendant: "Finally, the prejudice to the defendant must be considered based on three factors: (1) whether there has been oppressive pre-trial incarceration; (2) the anxiety and concern of the accused; and (3) the possibility of harm to the accused's defense."[16] Brooks concedes that there was no oppressive pre-trial incarceration and nothing more than the usual anxiety and concern of an accused. However, he claims that his defense has been harmed because he is unable to locate two witnesses.
Contrary to Brooks' claim, despite the substantial delay in this case, there is not a presumption of actual prejudice because he failed to timely assert his right to a speedy trial and the defense contributed to the delay by intentionally not taking steps to move the "sleeping dog" case forward.[17] As for the two purportedly missing witnesses, one of them testified at the first trial, was subjected to a thorough cross-examination, and the state has agreed to stipulate to that witness' prior testimony. While actual testimony at a re-trial is certainly preferable, "by obtaining this stipulation, the trial court alleviated the prejudice alleged by [Brooks]."[18] With regard to the other witness, who did not testify at the first trial, Brooks "must show that [he] could supply material evidence for the defense. [Cit.]"[19] Brooks has failed to make this showing, and has thus failed to demonstrate harm to the defense.
*114 Having balanced the four Barker factors, "we conclude that the trial court properly ruled that [Brooks] could not prevail on his claim that he was denied his constitutional right to a speedy trial."[20]
Judgment affirmed.
