Filimon Castillo Perez (“defendant”) appeals from an Order of the district court dismissing his petition for a writ of habeas corpus. He contends that a fifteen month delay between his guilty plea in state court on burglary charges, and sentencing following an habitual criminal proceeding violated his Sixth Amendment right to a speedy trial. He further contends that delay in bringing the habitual criminal charge violated his Fifth Amendment right to due process. Those arguments were presented to and rejected by the New Mexico Court of Appeals, which affirmed defendant’s conviction and sentence in state distriсt court. The New Mexico Supreme Court denied certiorari. Defendant then petitioned for a writ of habeas corpus from the federal district court. The United States Magistrate reviewed the case, proposed findings, and recommended dismissal. The district court adopted the proposed findings as its own and dismissed defendant’s petition with prejudice. This appeal followed. After reviewing the Record and examining defendant’s arguments, we affirm.
BACKGROUND
On February 2, 1981, defendant was indicted by the Bernalillo County, New Mexico, grand jury on one count of commercial burglary and one count of possession of burglary tools. He was arrested and held in the Bernalillo County Detention Center in lieu of bond. At a hearing on May 15, 1981, he pleaded guilty to both counts, and indicated through his counsel that he wished to be sentenced immediately in order to get to the state penitentiary. At that point, the judge asked the prosecutor what the effect of immediate sentencing would be. He responded that, in his opinion, an immediate sentence could not be suspended or run concurrently with any enhancement sentence later imposed pursuant to the New Mexico Habitual Criminal Act, N.M.Stat.Ann. §§ 31-18-17 to 31-18-20 (1978 & Supp.1981). He also advised the court that his office intended to initiate sentence enhancement proceedings against the defendant pursuant to that Act.
The judge was unwilling to impose a sentence upon defendant until the presen-tence report was prepared and the habitual offender matter resolved. She stated it was her desire to preserve the option of suspending defendant’s underlying sentence and crediting his jail time to the enhancement sentence. The court instructed the prosecutor to begin habitual offender proceеdings as soon as possible. Neither defendant nor his counsel made any objection to that reasoning or proposed course of action. However, defendant’s counsel stated to the prosecutor that defendant would admit to a fourth habitual offender charge, and wanted to be sentenced promptly.
Approximately nine months later, defendant’s former counsel learned that defendant was still in the county jail. He informally inquired of the prosecutor why defendant had not been sentenced, and conveyed defendant’s continued desire that sentencing рroceedings be promptly concluded. Shortly thereafter, on February 23, 1982, the public defender filed a motion for sentencing. A sentence date was set for March 19, 1982, then continued to April 2, 1982, at defendant’s request. At the hearing on April 2, 1982, defendant argued that the case against him should be dismissed because of delay in sentencing. The prosecutor responded by outlining difficulties encountered by his office in obtaining information necessary to the habitual criminal proceeding. He represented that his office was seeking evidence of five previous felonies, although it had mаterial for *252 three offenses which, if established for purposes of the statute, would result in the maximum sentence. He also reiterated his belief that immediate sentencing on the burglary conviction would be detrimental to the defendant with respect to a later enhancement sentence. Defendant’s counsel agreed that the matter should be deferred, and the trial judge postponed sentencing, in the defendant’s interest.
On that same day, April 2, 1982, the prosecutor’s office filed a supplemental information against defendant under the Habitual Criminal Act charging him with five felonies, including the immediate burglary conviction. Defendant was arraigned on April 30, 1982, and indicated he would contest the charge. On May 4, 1982, trial was set for June 2, 1982, on a trailing docket. On May 6 and May 10, 1982, the public defender’s office filed motions to dismiss the supplemental information on grounds that the delay in filing violated state rules of criminal procedure and defendant’s constitutional right to a speedy trial.
A hearing on those motions was held on May 28, 1982, at which time most of the points which are raised in this appeal were argued to the trial court. The prosecutor explained to the court his officе’s attempts to obtain evidence of previous convictions considered necessary for the habitual offender proceedings. The prosecutor explained that the task of gathering the necessary documents had been assigned to a paralegal. Testimony from that individual indicated that evidence with respect to three of the prior felony convictions had been obtained by the end of April 1981; part of the evidence with respect to another conviction was received in May of 1981 and the rest on March 15, 1982, after delays which the paralеgal was told to expect. Some possibly unnecessary information with respect to another felony conviction was obtained on April 23, 1982. Both the paralegal and the prosecutor in charge of the enhancement proceeding were under the impression that defendant would admit to the supplemental information once it was prepared. When it was learned that defendant would contest the habitual offender charge, a new information was prepared without one of the convictions in question.
The trial court denied defendant’s motion to dismiss, finding thаt the state’s delay was justified and in good faith, and not an attempt to circumvent the state time limit rule. The court also found that defendant was not prejudiced by the delay and in fact may have benefited. Due to defendant’s motion to dismiss, the June trial setting was continued until August, and on July 15,1982, the trial was placed on the trailing docket beginning the week of August 3, 1982. On August 19, 1982, defendant’s counsel filed a motion to dismiss certain counts of the supplemental information on the grounds that defendant’s prior convictions were invalid because his constitutional rights had been violated. Prior to trial, the court granted the motion with respect to one of the prior felony convictions and denied the motion with respect to all others. A jury trial was held on August 24 and 25, 1982. At the conclusion of the state’s case, defense counsel renewed the speedy trial and due process motions, which again were denied. The jury found that defendant had been convicted of four felonies as charged in the habitual offender information. The trial judge began the sentencing hearing immediately after the verdict. At the conclusion of the sentencing hearing, the court sentenced defendant to eighteen months on eаch of the underlying burglary convictions, to be served concurrently. It then suspended execution of those sentences. In addition, the court sentenced defendant to a mandatory eight years of imprisonment pursuant to the Habitual Offender Act, and one year of parole following his release. R.Vol. I at 171. Defendant received credit for 563 days of presentence confinement.
SIXTH AMENDMENT RIGHT TO A SPEEDY TRIAL
A. Delay in Sentencing on the Burglary Conviction.
Defendant claims that the fifteen month delay between his guilty plea and final
*253
sentencing violated his right to a speedy trial as guaranteed by the Sixth Amendment.
1
In
Pollard v. United States,
Because “the right to a speedy trial is a more vague concept than other procedural rights,”
Barker v. Wingo,
Certain factors, however, should be taken into consideration. In
Pollard
the Supreme Court said “[t]he delay must not be purposeful or oppressive.”
Pollard v. United States,
We can do little more than identify some of the factors which сourts should assess in determining whether a particular defendant has been deprived of his right. Though some might express them in different ways, we identify four such factors: Length of delay, the reason for the delay, the defendant’s assertion of his right, and prejudice to the defendant.
Barker v. Wingo,
We note at the outset that the factors set forth in
Barker
are guidelines, not rigid tests. As the Court stated, no single factor is “either a necessary or sufficient condition to the finding of a deprivation of the right of speedy trial.”
Barker,
The first question is whether the fifteen month delay between defendant’s plea of guilty and sentencing is sufficiently long to trigger the necessity for further inquiry. “Until there is sоme delay which is presumptively prejudicial, there is no necessity for inquiry into the other factors that go into the balance.”
Barker v. Wingo,
In analyzing the length of delay, it is “impossible to determine with precision when the right has been denied. We cannot definitely say how long is too long in a system where justice is supposed to be swift but deliberate.”
Barker,
Accordingly, we next assess the reasons for delay. In so doing we draw guidance from
Pollard,
a delay in sentencing case. There, the Supreme Court declared that the delay must not be purposeful.
Defendant contends that the court need not have deferred sentencing in order to preserve its options to benefit the defendant at a later sentеnce enhancement proceeding. But he does not deny the good faith purpose of that initial delay as an attempt to act in his best interests. Furthermore, he fails to identify one iota of real advantage the government gained or could reasonably have been expected to gain by a delay in his sentencing.
Defendant also contends that the government did not require ten and one-half months 6 to prepare its habitual criminal case. He argues that he would have stipulated, in effect pleaded guilty, to the felony convictions underlying the habitual offender charge (although he later denied the validity of the underlying convictions, and demanded a trial). He also argues the government had enough evidence to proceed in the spring of 1981. Finally, he charges unnecessary delay, general incompetence, and neglect in the collection of evidence. We reject these arguments. The possibility that the government could have chosen different or more expeditious methods of proceeding, and thus saved several months time, raises no constitutional violation. The record establishes that a staff member in thе district attorney’s office was assigned to and worked on the collection of evidence. It also establishes that the attorney assigned to the case checked on the evidence collection process at least once a month. Some materials were not received until March and April 1982. We do not suggest the prosecutor’s office was negligent. However, even if there were negligence in the preparation of the sentence enhancement case, resulting in the sentencing delay in question, it would not amount to a violation of defendant’s speedy trial rights.
Next, we address the question of defendant’s assertion of his speedy trial right. *256 Defendant argues at length that the government was aware from the outset that defendant desired to be sentenced promptly so that he could be transferred to the state penitentiary at Santa Fe. It is clear, however, that at the time defendant pleaded guilty neither he nor his counsel objected to the court’s reasoning that it would be in defendant’s best interests to defer sentencing. The record also establishes that no formal motion was filed by defendant until nine months later; that somе of the delay was occasioned by the hearing on that motion; and that defendant’s counsel requested a continuance at one point. Thus we are satisfied that at least part of the fifteen month delay was at the instance or with the acquiescence of defendant and his counsel. 7 In any event, the question of defendant’s assertion or waiver of his speedy trial right is not decisive in this case.
Finally, we turn to the question of prejudice. While a showing of prejudice may not be absolutely necessary in order to find a Sixth Amendment violation,
Moore v. Arizona,
Most of those interests diminish or disappear altogether once there has been a conviction. Because the rights of society proportionately increase, the prejudice claimed by the defendant must be substantial and demonstrable. 8 We proceed to evaluate defendant’s claims of prejudice, therefore, in the context of his status as a convicted felon, not as an accused person awaiting trial. All but one of defendant’s numerous claims of prejudice are based on the comparative benefits of the New Mexico State Penitentiary at Santa Fe over the Bernalillo County jail: potential good-time credits if the defendant’s conduct was good or if he engaged in various programs or performed exceptionally meritorious service; pay for prison labor; inmate release programs; rehabilitative and recreational programs; protection; possibly better medical treatment for an alleged hearing problem; and the opportunity to earn a less restrictive security level. He also argues that he suf *257 fered from anxiety by not knowing what sentence he would serve. No decision on point is cited by defendant in support of his propositions, 9 and we have found none. Furthermore, neither the state courts, nor the federal magistrate, nor the district court, found any evidence of prejudice to the defendant which rose to the level of a constitutional violation.
The benefits arguably available to defendant in the penitentiary are entirely speculative not only concerning whether he would have qualified, but also concerning the extent to which he would have particiрated or benefited. There is no record at all with respect to the alleged medical problem.
10
Speculative allegations of injury are unpersuasive.
See United States v. Huffman,
Post-conviction, pre-sentence anxiety is briefly mentioned by the defendant, citing
State v. Cunningham,
Having analyzed defendant’s argument within the framework of the factors set forth in Barker, we conclude that the delay in sentencing did not deprive the defendant of his right to a speedy trial.
B. Habitual Offender Charge.
The New Mexico Habitual Criminal Act, N.M.Stat.Ann. §§ 31-18-17 to 31-18-20 (1978 & Supp.1981), provides for longer, mandatory sentences to be imposed on repeat felony offenders. “The statute does not create a new offense but merely provides a proceeding for enhancing sentences.”
State v. Nelson,
Defendant next argues that if the habitual offender proceeding was separate for Sixth Amendment purposes, then there was unconstitutional delay in bringing that charge to trial. He reasons that his speedy trial right attached at the hearing where he pleaded guilty to the burglary charges, because the prosecutor “publicly announced ... his intention to file____” Appellant’s Brief at 17. Defendant points to his continued incarceration in the county jail instead of the penitentiary as “ ‘the actual restrains [sic] [of] arrest’ on the forthcoming supplemental information,” Appellant’s Brief at 17 (citing
United States v. Marion,
Sixth Amendment speedy trial rights do not apply to preindictment or preinformation delay. “Events which trigger Sixth Amendment protection are the formal indictment or information or else the actual restraints imposed by arrest and holding to answer a criminal charge____”
United States v. Marion,
Accordingly, we hold that defendant was not deprived of his right to a speedy trial with respect to the habitual offender proceeding.
DUE PROCESS CLAIM
Defendant’s alternate theory is that the delay in bringing the habitual of
*259
fender information was a violation of his Fifth Amendment due process rights. The Supreme Court has held that although a defendant’s primary protection against the government’s prosecution of overly stale claims is the statute of limitations, the Fifth Amendment’s due process clause does have a “limited role to play in protecting against oppressive delay.”
United States v. Lavasco,
The district court’s judgment dismissing defendant’s petition for а writ of habeas corpus is hereby affirmed.
Notes
. The Sixth Amendment provides: "In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial____”
The right to a speedy trial is "fundamental” and is imposed by the Due Process Clause of the Fourteenth Amendment on the states.
Dickey
v.
Florida,
.
In
Barker v. Wingo,
. At least two state courts have so held.
See State v. Drake,
. In the opening paragraph of its decision in
Barker
the Supreme Court referred to the five
*254
previous cases (including
Pollard)
in which it dealt with the Sixth Amendment right to a speedy trial and the Court stated that "in none of these cases have we attempted to set out the criteria by which the speedy trial right is to be judged."
. It is not uncommon for a court to postpone sentencing. In
United States v. Pruitt,
. This interval was between defendant’s guilty plea on May 15, 1981, and the date on which the habitual criminal information was filed, April 2, 1982.
. Defendant was without counsel during a large part of the period in question, but was represented at the times indicated.
. Of course, the defendant is still entitled to due process.
. Most of defendant’s cited authorities deal with pre-trial delay and must be read in the context of prejudice suffered by an accused, not a convicted defendant.
See, e.g., Strunk v. United States,
. There must be some showing of a causal relationship between delay and thе prejudice claimed,
Brooks v. United States,
. The habitual offender proceeding in this case probably was a separate proceeding for Sixth Amendment purposes. In characterizing such a proceeding, the New Mexico Supreme Court stated "the charge is serious and the potential for prejudice against unrepresented defendants is so great that a right to counsel has been recognized____ [T]he proceeding possesses several characteristics of a trial (right to counsel, right to jury, rules of evidence, etc). The statute itself refers to the defendant’s ‘right to be
tried
as to the truth’ of the allegations of the information.”
