Opinion for the Court filed by Circuit Judge HARRY T. EDWARDS.
This appeal raises statutory and constitutional challenges to the authority of the United States Attorney for the District of Columbia to “transfer” criminal cases from the District of Columbia courts to U.S. District Court. The three appellees in these consolidated appeals were initially charged in District of Columbia Superior Court, but those charges were later dropped in favor of a subsequent prosecution in federal court for the same criminal conduct, effectively “transferring” the cases from one court system to the other. With respect to one of the appellees, a federal indictment was not filed until more than a year after his arrest; with respect to the other two appellees, the federal indictments were filed more than seven months after arrest.
In the federal forum, the appellees contended that the transfer of their cases and the delay occasioned by it violated the Speedy Trial Act, 18 U.S.C. §§ 3161
et seq.
(1988), the due process clause of the Fifth Amendment and.the speedy trial clause of the Sixth Amendment. The federal trial court dismissed all charges against the ap-pellees after finding violations of the Speedy Trial Act and the due process clause.
See United States v. Holland,
At oral argument before this court, the appellees focused their arguments upon the Speedy Trial Act and Sixth Amendment claims, leaving aside much of the District Court’s reliance on the due process clause. Although we reverse the District Court’s judgments premised on the Speedy Trial Act and the due process clause, we remand for fuller consideration of the appellees’ claim that the processing of their cases violated the speedy trial clause of the Sixth Amendment.
I. BACKGROUND
The three appellees in these consolidated appeals, Vernon L. Holland, Albert E. Mills and Kenneth B. Wonson, were each arrested in the District of Columbia (“District” or “D.C.”) for possession of cocaine with intent to distribute. The U.S. Attorney for the District of Columbia, who acts as the chief prosecutor in both the D.C. courts and the federal courts for the District of Columbia, elected initially not to prosecute the three men in federal court and instead indicted each appellee in D.C. Superior Court for violations of the D.C.Code.
1
In April 1989, the same month in which appel-lees Holland and Mills were indicted in Superior Court, high-ranking officials in the Bush administration announced a new initiative to crack down on drug-related crime in the nation’s capital. As part of that effort, officials adopted a new policy to bring more D.C. drug cases in federal court in order to take advantage of the stricter penalties available under the federal sentencing guidelines. Accordingly, the U.S. Attorney’s office reviewed case files pending in Superior Court with an eye toward transferring the more serious cases to the federal system. The Assistant U.S. Attorney in charge of the review stated that cases were selected on the basis of criteria relating, among other things, to the gravity of the offense, the defendant’s criminal history and the amount of drugs involved.
See Holland,
Sometime in May or June of 1989, the appellees’ cases were selected for “transfer” to federal court. The U.S. Attorney's office obtained federal indictments against the appellees based on exactly the same conduct underlying the D.C. charges and, as their Superior Court trial dates approached, had the D.C. charges dismissed *458 in order to pursue the federal charges. 2 The sequence of events with respect to each of the appellees was as follows:
[[Image here]]
After the cases reached federal court, however, the trial judge dismissed charges against two of the appellees — Albert Mills and Kenneth Wonson — on the grounds that the delay incident to the transfers violated the Speedy Trial Act and that the transfers more generally offended due process.
See Roberts,
The trial court’s conclusion that the
Speedy Trial Act
had been breached was founded upon a straightforward reading of the statute, which requires that a federal indictment be filed within 30 days of an arrest “in connection with such charges.” 18 U.S.C. § 3161(b) (1988). Because the federal indictments came many months after the arrests of Holland, Mills and Won-son, the trial court ruled that the charges had to be dismissed.
See Roberts,
The trial court’s conclusions concerning the
due process clause
were more wide-ranging. The court’s opinions suggested that the timing of the transfers, following closely upon the defendants’ rejection of Government plea offers in Superior Court, might betray an abuse of prosecutorial power.
See Holland,
In focusing on sentencing under federal versus local statutes, the trial court found that the Sentencing Reform Act of 1984, Pub.L. No. 98-473, 98 Stat. 1987, and the sentencing guidelines promulgated pursuant to it, violated due process by diminishing judicial discretion in sentencing and by enhancing the ability of prosecutors to influence sentencing through the selection of charges. “In short,” the District Court found that “the prosecutor’s selection of the charges available to him from his large arsenal amounts ... to an almost totally precise selection of the ultimate sentence to
*459
be imposed upon conviction or plea of guilty.”
Roberts,
The Government now appeals from the District Court’s orders dismissing all charges against the appellees.
II. Analysis
A. The Speedy Trial Act
The Speedy Trial Act requires that [a]ny information or indictment charging an individual with the commission of an offense shall be filed within thirty days from the date on which such individual was arrested ... in connection with such charges.
18 U.S.C. § 3161(b) (1988). If the indictment is not brought within 30 days of that arrest, the federal charges must be dismissed. 18 U.S.C. § 3162(a)(1) (1988).
The District Court found that the appel-lees’ federal indictments violated the Speedy Trial Act because they came many months after the appellees’ arrests.
See Roberts,
This circuit has held that, for purposes of the Speedy Trial Act, “a District of Columbia arrest should be treated as a state arrest” so that a federal indictment need not be brought within 30 days of a defendant’s apprehension if that arrest was initially premised upon violations of the D.C. Code rather than federal law.
See United States v. Robertson,
It is beyond dispute that ... [the Speedy Trial Act] does not prevent the *460 government from indicting a defendant on federal charges more than thirty days after his arrest on similar state charges. “Since the Act applies only to federal prosecutions it is only a federal arrest, not a state arrest, which will trigger the commencement of the time limits set in the Act.” Courts have applied this principle even where the federal charges are based on the very conduct occasioning the state arrest, where the state arrest is the product of a joint state-federal operation, with federal officers participating in every stage of the planning and execution, and where the purpose of the later federal prosecution is to salvage a prosecution after the state authorities ran afoul of state speedy trial limitations.
Thus the only question for this court is whether a District of Columbia arrest should be treated as a state arrest for these purposes. [We a]nswer[] that question in the affirmative....
Id. at 256 (citations omitted; emphasis in original).
Robertson controls the statutory question presented in this case. Holland, Mills and Wonson were each arrested by D.C. police and then presented and indicted in D.C. Superior Court on charges of violating D.C. law. Under Robertson, the fact that the later federal indictments were based upon the very conduct underlying the initial D.C. charges is immaterial. By Robertson’s, measure, these are “District arrests” and do not trigger the Speedy Trial Act clock.
The appellees and
amici
argue vigorously that
Robertson
was wrongly decided. They point out that the federalism concerns that animate the decisions upon which
Robertson
relied are for the most part inappo-site in the District of Columbia, where the U.S. Attorney manages both “local” and federal prosecutions. Other circuits have differentiated between federal and state arrests on the grounds that federal prosecutors should not be held accountable under the Speedy Trial Act for the timing of local arrests and prosecutions over which they have no control and but limited influence.
See, e.g., Iaquinta,
The question remains whether
Robertson
is somehow distinguishable from the instant cases. The District Court found
Robertson
inapposite on the grounds that no allegation had been raised in that case of
intentional
prosecutorial manipulation of the indictments in order to circumvent the Speedy Trial Act.
See Holland,
Although the trial court suggested the possibility of prosecutorial misconduct in connection with the transfer of cases from Superior Court to federal court, we find absolutely nothing in the record to support *461 this charge. Indeed, apart from citing the Government’s desire to secure the advantage of stiffer sentences under the federal statute — which alone is not evidence of any wrongdoing by the U.S. Attorney — the ap-pellees do not even hint of prosecutorial misconduct in their defense of the District Court’s judgments below. Therefore, on the record before us, such a claim cannot furnish a basis for departing from Robertson in this case. See also parts B.l and B.2 infra.
The only other imaginable basis for distinguishing Robertson — and the basis urged upon us by the appellees — is that the arrest in Robertson was originally spurred by charges — second-degree murder — for which Robertson could not have been indicted in federal court, whereas the appel-lees here were arrested on charges that were from the start capable of indictment in either forum. We cannot adopt this approach, however, because there is no suggestion in Robertson that this factual peculiarity was integral to the court’s reasoning.
Because Robertson is the controlling law of this circuit and because it cannot be faithfully distinguished from the facts of the cases before us, we find that the appel-lees’ Speedy Trial Act claims must fail. The appellees’ arrests were “District arrests” and did not trigger the Speedy Trial Act requirement that a federal indictment be brought within 30 days of an arrest “in connection with” federal charges.
B. Due Process
The District Court rested its finding that due process had been violated by the case transfers on a wide range of considerations, including the allegedly “arbitrary” way in which the U.S. Attorney had selected the cases to be transferred, the fact that the U.S. Attorney did not promptly notify the defendants of his intention to transfer their cases and, most of all, the enhanced power of the prosecutor to obtain harsher and more definite criminal penalties in the federal forum. Analysis of the appellees’ due process claims requires a focused consideration of the prosecutor’s practices in light of established due process theories.
Some of the prosecutorial powers about which the District Court expressed concern are clearly beyond constitutional challenge. It is established, for example, that the U.S. Attorney for the District of Columbia may elect to prosecute a given criminal defendant on federal rather than District charges, even though the former carry stiffer penalties.
See Hutcherson v. United States,
Nor are we free to embrace the District Court's suggestion that the Sen. tencing Reform Act and the associated guidelines violate due process by shifting influence over sentencing from the judiciary to the prosecutor. The District Court's opinion is premised upon two beliefs. The first is that due process entitles a criminal defendant to an individualized sentence crafted by the exercise of judicial discretion-a contention that has been uniformly rejected by other circuits.
3
The second, also widely rejected,
4
is that due process cannot tolerate a related enhancement of the prosecutor's influence over sentencing. We do not doubt that judicial discretion in sentencing is of long standing in our criminal system
5
and that there may well be pitfalls, from a standpoint of sound policy, in the substantial enlargement of the prosecutorial role in such decisions.
6
At the same time, however, the Supreme Court has made clear that "federal sentencing ... never has been thought to be assigned by the Constitution to the exclusive jurisdiction of any one of the three Branches of Government." Mistretta v. United States,
Thus, we are constrained to reject the District Court's conclusion that the Sentencing Reform Act and the guidelines promulgated thereunder are fundamentally offensive to due process because they re *463 duce judicial discretion and enlarge prose-cutorial influence in sentencing. Accordingly, we must also reject the trial court’s conclusion that the transfers at issue here violate due process because they subjected the appellees to sentencing under that system.
This leaves only two possible bases for finding a due process violation in these cases: that the prosecutor’s transfer decisions were in some sense vindictive and in retaliation for the exercise by a defendant of his legal rights, or that the prosecutor’s delay in obtaining a federal indictment was orchestrated deliberately to exact a tactical litigation advantage and substantially prejudiced the defendant.
1. Vindictive Prosecution
Due process clearly protects criminal defendants against prosecutorial or judicial action intended as a penalty for a defendant’s exercise of constitutional rights.
See Blackledge v. Perry,
The trial court observed that
[i]n case after case, the particular defendant whose case was transferred had declined to plead guilty in Superior Court prior to his indictment in this Court. Indeed, in several instances, the relationship between the refusal to enter a guilty plea and indictment in federal court was explicitly spelled out.
Holland,
The lesson of Goodwin is that proof of a prosecutorial decision to increase charges after a defendant has exercised a legal right does not alone give rise to a presumption [of vindictiveness] in the pretrial context. The rationale supporting the Court’s teaching is that this sequence of events, taken by itself, does not present a “realistic likelihood of vindictiveness.”
Meyer,
Moreover, the fact that the prosecutor warned some defendants in plea negotiations that their cases would be transferred if they did not plead guilty does not violate due process.
See Bordenkircher v. Hayes,
2. Pre-Indictment Delay
Dismissal of the appellees' indictments might also have been justified on grounds of excessive pre-indictment delay. Such delay offends due process if the defendant can carry the burden of showing
(1) that the government delayed bringing the indictment in order to gain a tactical advantage; and (2) that the delay caused him actual and substantial prejudice.
United States v. Fuesting,
Here, the District Court's factual findings are insufficient to satisfy these requirements and the appellees elected not to press this line of reasoning. Although the District Court did offer some generalized observations about the potential impact of delay in typical cases and about advantages gained by prosecutors as a result of delay, these did not amount to the sort of defendant-specific findings necessary to make out a due process violation on grounds of pre-indictment delay. Cf Fuesting,
In sum, employing established constitutional theories, we are unable to sustain the District Court's conclusion that the transfers at issue here violated the due process clause of the Fifth Amendment.
C. The Sixth Amendment
Finally, at oral argument, the ap-pellees renewed their claim that the delay between their arrests and their eventual federal trials violated their Sixth Amendment rights to a speedy trial. This presents a distinctly different question from that raised by the appellees' statutory speedy trial claim. The constitutional calculus, unlike the statutory analysis, turns not on precisely defined time limitations but rather on a broad balancing of considerations. See Barker v. Wingo,
Moreover, as Government counsel readily conceded, Sixth Amendment analysis would comprehend the entire time span from the
*465
appellees’ indictment in Superior Court to the dismissal of the federal charges against them, given that the same federal prosecutors controlled both prosecutions.
See United States v. Liddy,
Although the appellees raised their Sixth Amendment claim below, the District Court confined its analysis to the Fifth Amendment and statutory questions. It is therefore necessary to remand to the District Court for full consideration of whether the transfers at issue here violated the appellees’ Sixth Amendment rights. Such consideration will, of course, require a highly fact-specific analysis of the appellees’ own particular cases, guided by the balancing test prescribed by the Supreme Court in Barker.
III. Conclusion
For all of the foregoing reasons, we reverse the District Court’s conclusions that the “transfers” at issue here violated the Speedy Trial Act and the due process clause of the Fifth Amendment. We remand to the District Court, however, for initial consideration of the appellees’ claims that they were deprived of their Sixth Amendment rights to a speedy trial.
So ordered.
Notes
. All three appellees were charged with violating D.C.Code Ann. § 33-541 (1988) (possession of cocaine with intent to distribute). In addition, Wonson was charged with assault on a police officer in violation of D.C.Code Ann. § 22-505(a) (1988).
See Roberts,
. Wonson was indicted in U.S. District Court on September 12, 1989, on charges of violating 21 U.S.C. §§ 841(a) & (b)(l)(A)(iii) (1988) (possession with intent to distribute 50 grams or more of cocaine base) and D.C.Code Ann. § 22-505(a) (1988) (assault on a police officer). Charges against Wonson in D.C. Superior Court were dismissed on October 11, 1989, on a Government motion.
See Roberts,
Holland and Mills were each indicted in U.S. District Court on September 21, 1989, on charges of violating 21 U.S.C. §§ 841(a) & (b)(l)(B)(iii) (1988) (possession with intent to distribute five grams or more of cocaine base) and 18 U.S.C. § 2 (1988) (aiding and abetting). Superior Court charges against the two were dismissed on October 17, 1989, following a request by the Government.
