OPINION OF THE COURT
I.
Thе district court of the Virgin Islands dismissed with prejudice an information charging defendant Desmond Bryan with grand larceny in violation of 14 V.I.C. 1083(1) and possession of stolen property in violation of 14 V.I.C. 2101(a). The court found that the information was filed more than 30 days after Bryan’s arrest and held that it was untimely under the provision of the Speedy Trial Act, 18 U.S.C. § 3161(b), which requires that an information be filed within thirty days of arrest.
The United States Attorney argued that the Speedy Trial Act does nоt apply to territorial offenses, and that in any event dismissal should be without prejudice because the short additional time taken in filing the information (which was filed 35 days after Bryan’s arrest on these charges) was to permit the government to ascertain whether the value of the jeep seat allegedly stolen by Bryan exceeded $100, an element of the crimes charged. In rejecting the prosecution’s argument that the Speеdy Trial Act was inapplicable to territorial offenses prosecuted in the district court, the district court relied upon the fact that the Administrative Office of the United States Courts and this court had acted as if the Speedy Trial Act applied to territorial offenses by purchasing a Speedy Trial Reporter for the district court. App. at 20. The court also stated that “any Act passed by the Legislature of the Virgin Islands is an Act of Congress.” App. at 20. Finally, the court suggested that it was within the supervisory power of the circuit court to apply the provisions of the Speedy Trial Act to local offenses. App. at 21. The district court stated that it would dismiss the indictment with prejudice in the hope that the government would appeal to this court to resolve the question. App. at 20.
Accordingly, before us are the following questions: (1) Does the Speedy Trial Act apрly of its own force to territorial offenses prosecuted in the district court of the Virgin Islands? (2) If not, does the District Court of the Virgin Islands have the authority to make the provisions of the Speedy Trial Act applicable to territorial offenses prosecuted in that court by virtue of a Speedy Trial Plan approved by the Judicial Council of the Third Circuit? (3) If there is such authority, does the Speedy Trial Plan adopted do so? and (4) If so, did the distriсt court abuse its discretion by dismissing the information against Bryan with prejudice?
II.
The provisions of the Speedy Trial Act limiting the time for bringing an indictment or information, 18 U.S.C. § 3161(b), and providing for dismissal for failure to do so within the time limit, 18 U.S.C. § 3162(a)(1), apply only when the defendant is charged with an “offense”. The statute defines an “offense”, in relevant part, as “any Federal criminal offense which is in violation of any Act of Congress and is triable by any court established by Act of Congress.” 18 *1072 U.S.C. § 3172(2). Thе latter part of the definition is met here because the crimes with which Bryan was charged are triable in the District Court of the Virgin Islands, which is a “court established by Act of Congress.” 1 See 48 U.S.C. § 1611(a). However, the crimes for which Bryan was charged were established by an Act of the Legislature of the Virgin Islands, not an Act of Congress.
The district court’s suggestion that an Act passed by the Legislature of the Virgin Islands is an Act of Congress is contrary to this court’s precedent. Under the Revised Organic Act, the “legislative power and authority of the Virgin Islands shall be vested in ... the ‘Legislature of the Virgin Islands’,” 48 U.S.C. § 1571(a), and “shall extend to all rightful subjects of legislation not inconsistent with [the Revised Organic Act] or the laws of the United States made applicable to the Virgin Islands.” 48 U.S.C. § 1574(a).
In
Harris v. Boreham,
With the passage of the Revised Organic Act, Congress intended to grant “a greater degree of autonomy, economic as well as political, to the people of the Virgin Islands.”
Virgo Corp. v. Paiewonsky,
The Territory of the Virgin Islands is a body politic. While not sovereign, in the true sense of that term, the Revised Organic Act has conferred upon it attributes of autonomy similar to those of a sovereign government or a state.
It follows that territorial crimes established by the Legislature of the Virgin Islands are not criminal offenses in violation of an Act of Congress and hence are not “offenses” within the meaning of the Speedy Trial Act.
Cf. Government of the Virgin Islands v. Ortiz,
III.
Although the Speedy Trial Act does not apply by its own terms to territorial offenses prosecuted in the district court, the District Court of the Virgin Islands is not without the power to extend some or all of the provisions of that Act to all cases tried before it. Such authority stems from Rule 50(b) of the Federal Rules of Criminal Procedure, as well as the inherent power of courts to supervise criminal proceedings before them.
The Federal Rules of Criminal Procedure apply to all criminal proceedings in the District Court of the Virgin Islands. Fеd.R.Crim.P. 54(a). Fed.R.Crim.P. 50(b) *1073 provides that “each district court shall conduct a continuing study of the administration of criminal justice in the district court and before United States magistrates of the district and shall prepare plans for the prompt disposition of criminal cases in accordance with the provisions of [the Speedy Trial Act].”
Even before the passage of the Speedy Trial Act, courts relied on the language of the earlier version of Rule 50(b) to promulgate speedy trial plans. The earlier version of Rule 50(b), in effect as of October 1972, also provided that each district court “shall prepare a plan for the prompt disposition of criminal cases” within its district. Fed.R.Crim.P. 50(b) (West 1976). The Administrative Office of the United States Courts submitted a Model Plan to each district court, and many adopted a version of that plan. See H.R.Rep. No. 1508, 93d Cong., 2d Sess., reprinted in 1974 U.S. Code Cong. & Admin.News 7401, 7405-06.
The authority to promulgate such plans was upheld in
United States v. Furey,
A similar result was reached by the Fifth Circuit. In
United States v. Novelli,
Although Rule 50(b) presently provides that the district courts shall prepare plans for the prompt disposition of criminal cases “in accordance with” the provisions of the Speedy Trial Act, we construe this only as precluding any timetable inconsistent with the Act. Nothing in the Rules suggеsts that plans can only be adopted if the Speedy Trial Act applies. If Rule 50(b) were construed as so limited, it would be duplicative of the provisions already contained in the Speedy Trial Act. See 18 U.S.C. §§ 3165, 3166. In fact, the Administrative Office of the United States Courts transmitted its Model Plan to the federal courts with the suggestion that “district courts with jurisdiction over offenses created by other legislatures will wish to consider the extent to which Speedy Trial Act standards should be applied to trials for such offenses.” Transmission #30, Dec. 14, 1979.
The Advisory Committee explains that the change in language in Rule 50(b) was needed to take account of the enactment of the Speedy Trial Act, and expresses the belief that “[a]s the various provisions of the Act take effect ... they and the district plans adopted pursuant thereto will supplant the plans heretofore adopted under rule 50(b).” In the absence of any legislative history to the contrary, we view the reasoning of the cases cited above as ample basis for holding that Rule 50(b) continues to provide authority for the promulgation by the District Court of the Virgin Islands of a plan for the prompt dispo *1074 sition of criminal cases tried before it, including those cases based on territorial crimes, despite the inapplicability to such cases by the terms of the Speеdy Trial Act.
Moreover, even if Rule 50(b) were narrowly construed to apply only where the Speedy Trial Act applies, we believe the Circuit Judicial Council has power to approve the Speedy Trial Plan promulgated by the District Court of the Virgin Islands.

Under 28 U.S.C. § 332(d)(1) “[e]ach judicial council shall make all necessary and appropriate orders for the effective and expeditious administration of justice within its circuit.”
See In re Imperial “400” National, Inc.,
This court has recognized that the administration of justice in the Virgin Islands may require application of the standards of certain federal legislation designed to protect the rights of criminal defendants to cases tried in the District Court of the Virgin Islands. Accordingly, we exercised our supervisory power to apply to the Virgin Islands provisions of fеderal statutes which did not apply by their own terms. For example, in
Government of the Virgin Islands v. Ortiz,
In doing so, the
Ortiz
case followed our earlier decision in
Government of the Virgin Islands v. Lovell,
We believe that the legislative gloss placed on the Jencks case by Congress; ... has resulted in a sound rule. Policy and logic dictate that such a rule shall obtain in all criminal prosecutions in the Virgin Islands.
Lovell,
Since the supervisory power that we exercised in those cases is analogous to thе authority given the Circuit Judicial Councils by section 332(d)(1), we conclude that that section authorizes the Circuit Judicial Council to approve the Speedy Trial Plan of the District Court of the Virgin Islands, *1075 which establishes rules and timetables for the prosecution of territorial crimes tried in that court and imposes sanctions for violation thereof.
IV.
We next consider whether the Speedy Trial Plan adopted by the District Court of the Virgin Islands and approved by the Judicial Council on June 26, 1980 applies to territorial offenses tried in the district court.
The Plan contains the following provisions:
II. STATEMENT OF TIME LIMITS AND PROCEDURES FOR ACHIEVING PROMPT DISPOSITION OF CRIMINAL CASES
Pursuant to the requirements of Rule 50(b) of the Federal Rules of Criminal Procedure, the Speedy Trial Act of 1974 (18 U.S.C. Chapter 208), the Speedy Trial Act Amendments Act of 1979 (Pub.L. No. 96-43, 93 Stat. 327), and the Federal Juvenile Delinquency Act (18 U.S.C. §§ 5036, 5037), the judges of the District Court of the Virgin Islands have adopted the following time limits and procedures to minimize undue delay and to further the prompt disposition of criminal cases and certain juvenile proceedings:
1. Applicability
(a) Offenses. The time limits set forth herein are applicable to all criminal offenses triable in this court, * including cases triable by United States magistrates, except for petty offenses as defined in 18 U.S.C. § 1(3). Except as specifically provided, they are not applicable to proceedings under the Federal Juvenile Delinquency Act. [§ 3172].
We need not decide whether the broad all-encompassing language in the text of the Plan making it applicable “to all criminal offenses triable in this court” is limited by the footnote referring to the definition of “offense” in the Speedy Trial Act. 4 That is because a subsequent section of the Plan dealing with the issue involved in this case, the failure to file an information within 30 days of Bryan’s arrest, unambiguously sets forth its applicability to territorial crimes. That section provides:
3. Time Within Whiсh an Indictment or Information Must Be Filed.
(a) Time Limits. If an individual is arrested or served with a summons and the complaint charges an offense to be prosecuted in this district, any indictment or information subsequently filed in connection with such charge shall be filed within 30 days of arrest or service [§ 3161(b) ].
(b) Measurement of Time Periods. If a person has not been arrested or served with a summons on a Federal or Territorial charge, an arrest will be deemed to have been made at such time as thе person (i) is held in custody solely for the purpose of responding to a Federal or Territorial official charge; (ii) is delivered to the custody of a Federal or Territorial official in connection with a Federal or Territorial charge; or (iii) appears before a judicial officer in connection with a Federal or Territorial charge. **
Because the language of the Virgin Islands Plan with respect to its сoverage of territorial crimes, at least insofar as it establishes the time within which an indictment or information must be filed, is neither general nor vague, it does not suffer from the defect in the Plan considered in
United States v. Felton,
V.
Finally, we must consider whether the district court abused its discretion in dismissing the charge against Bryan with prejudice.
In the sanction provision of the Virgin Islands Plan, it is provided that “nothing in this plan shall be construed to require that a case be dismissed or a defendant released from custody in circumstances in which such action would not be required by 18 U.S.C. §§ 3162 and 3164 [of the Speedy Trial Act].” Although the Speedy Trial Act and its sanctions are not by their own tеrms applicable to territorial offenses tried in the District Court of the Virgin Islands, nothing prevents that court from incorporating into its Plan the timetables and the sanctions applicable thereto from the Speedy Trial Act. This Plan does so. We reject the U.S. Attorney’s contention that “the Plan does not contain the teeth of the Act,” Appellant’s Brief at 17. Accordingly, we must look to the applicable statutory provision for sаnctions to ascertain whether the dismissal with prejudice in this case was appropriate.
The Speedy Trial Act provides that in determining whether to dismiss the case with or without prejudice when the information or indictment is not filed within the required time limit, the court shall consider,
inter alia,
the following factors: the seriousness of the offense; the facts and circumstances of the case which led to the dismissal; and the impact of a reprosеcution on the administration of the Speedy Trial Act and on the administration of justice. 18 U.S.C. § 3162(a)(1).
See United States v. Carrasquillo,
Even without such a controlling provision, we would anticipate that no criminal proceeding would be dismissed with prejudice without the court having considered and balanced the length of the delay, the reasons for the delay, and the prejudice from the delay to defendant.
See, e.g., United States v. Simmons,
When a district court dismisses an information or indictment with prejudice because there has been a failure to comply with the time requirements of the Speedy Trial Act, the court must state its reasons on the record setting forth fully the balancing which is required before such an action can be taken. Only with the benefit of the district court’s reasoning will we be able to fulfill our appellate function. In this case there is no indication that the district court considered any of the statutory factors in dismissing the information against Bryan with prejudice. Instead, the only reason given by the district court for dismissing with prejudice was its “hope the government would take it and let the circuit court say whether the Speedy Trial Act applies or not.” App. at 20. It is therefore evident that the order must be vacated and the case remanded to the district court so that it can consider the relevant factors and make the required on record balancing.
VI.
In summary, we have concluded that (1) the Speedy Trial Act does not apply by its own terms to territorial offenses tried in the District Court of the Virgin Islands; (2) *1077 'the district court had the power to promulgate a Speedy Trial Plan, approved by the Circuit Judicial Council, which extended the provisions of the Plan to territorial offenses tried in that court 5 ; (3) the рrovisions of the Speedy Trial Plan for the disposition of criminal cases in the District Court of the Virgin Islands, approved by the Circuit Judicial Council June 26, 1980, establishing the time within which an indictment or information must be filed apply to territorial offenses tried in the District Court 6 ; (4) the district court abused its discretion in dismissing with prejudice the information against Bryan because the court failed to engage in an on the record balancing of the factors which must be considered before an information or indictment is dismissed with prejudice.
For the foregoing reasons, we will vacate the order of the district court dismissing the information with prejudice, and will remand for further proceedings consistent with this opinion.
Notes
. We have no occasion to consider here the decision of the Territorial Court of the Virgin Islands holding that the Speedy Trial Act is inapplicable to criminal proceedings in the Territorial Court.
See Government of the Virgin Islands
v.
Quetel,
. Since the District Court of the Virgin Islands has the jurisdiction of a district court of the United States, see 48 U.S.C. § 1612, it also tries criminal offenses in violation of an Act of Congress which are expressly governed by the Speedy Trial Act. The legal material sent to the District Court by the Administrative Office is patently relevant to that aspect of the District Court’s jurisdiction.
. In
Henderson v. United States,
18 U.S.C. § 1372 [sic, actually § 3172] defines offense as "any Federal criminal offense which is in violation of any Act of Congress ...” The district courts with jurisdiction over offenses created by other legislatures will wish to consider the extent to which Speedy Trial Act standards should be applied to trials for such offenses.
The District Court of the Virgin Islands hereby adopts this plan in compliance with Rule 50(b), thus extending all Speedy Trial Act standards to proceedings resulting from criminal offenses which are in viоlation of statutes enacted by the Virgin Islands Legislature.
. This footnote, which was included in the Model Speedy Trial Plan prepared by the Administrative Office of the United States Courts, was obviously included by oversight in the Virgin Islands Plan itself.
. We have no occasion to consider whether the District Court retains the power to establish a Speedy Trial Plan for the Territorial Court. In any event, it is a matter which the Legislature of the Virgin Islands may wish to address.
. The District Court may want to review the language in its Plan in light of this opinion.
