OPINION
for the Court.
The applicant, Michael A. Ballard, appeals from a Superior Court judgment denying his application for postconviction relief. Mr. Ballard’s original conviction dates to December 3, 1979, when a jury found him guilty of a number of charges relating to the armed abduction of three teenagers. This case came before the Court for oral argument pursuant to an order directing the parties to appear and show cause why the issues raised in this appeal should not be summarily decided. After reviewing the parties’ written and oral submissions, we are satisfied that the issues presented may be resolved without the necessity of further briefing and argument. For the reasons set forth in this opinion we affirm the judgment of the Superior Court.
I
Facts and Procedural History
On March 8, 1979, three teenagers were abducted at gunpoint by Salvatore Savas-tano, Jr. 1 The gunman forced the children into an automobile and drove them to an isolated wooded area to meet Ballard and a third accomplice. Savastano released one of the teenagers on the way; when he reached the isolated area the other two were placed in the trunk of Ballard’s automobile. They were then taken to Jamestown, where they were held in an aban *266 doned ammunition bunker for over ten hours under Savastano’s watchful eye. The resourceful hostages eventually were released, however, after persuading Savas-tano that his accomplices had deserted him, at which point the extortion plot quickly unraveled. Soon thereafter, Sa-vastano was arrested at a roadblock that had been set up at the Newport Bridge. Later that evening, Ballard was arrested at a telephone booth while he was speaking to a Rhode Island State Police Lieutenant who was pretending to be the teenagers’ father.
Mr. Ballard initially was held by federal authorities. On March 16, 1979, a Rhode Island grand jury returned a nine-count indictment against him, and the state lodged a detainer with federal authorities to be enforced upon completion of the federal charges. The federal government ultimately dismissed all charges against applicant. Thereafter, the state presented federal authorities with a writ of habeas corpus and mittimus, removed Ballard from federal custody at the Federal Building and Courthouse in Providence, and transported him to the Adult Correctional Institutions.
After a jury trial, applicant was convicted of conspiracy to kidnap with intent to extort, two counts of kidnapping with intent to extort, kidnapping, three counts of assault with a dangerous weapon, and carrying a pistol without a license. He was sentenced to two life sentences plus sixty-five years, all of which were ordered to run consecutively.
Thereafter, Ballard filed a motion to reduce his sentence under Rule 35 of the Superior Court Rules of Criminal Procedure.
See State v. Ballard,
Also, on February 2, 1988, Ballard filed an application pro se for postconviction relief. In response to a request by applicant for additional time to engage an attorney, the original trial justice told him to “take whatever time you need” to select an attorney. Apparently, no further action was taken on this application until October 23, 2000, when Ballard filed a second application for postconviction relief. Counsel was appointed, and the application ultimately was heard and denied on July 21, 2005. Mr. Ballard filed a notice of appeal to this Court on July 26, 2005. The Superi- or Court entered judgment on June 8, 2006. 2

Standard of Review
Under Rhode Island law, “post-conviction relief is available to a defendant convicted of a crime who contends that his original conviction or sentence violated rights that the state or federal constitutions secured to him.”
Young v. State,
Ill
Analysis
On appeal, applicant raises four issues. First, he argues that Rhode Island did not have jurisdiction to prosecute him because he was not properly removed from federal custody and placed into state custody. Second, applicant asserts that his right to confrontation was violated because the statement of a witness was read into the record, and applicant never had an opportunity to cross-examine that witness. Third, he argues that the trial justice improperly instructed the jury on reasonable doubt. The applicant’s final contention is that his reduced sentence remains “manifestly excessive” and unconstitutional. 3
A
Removal From Federal to State Custody
Mr. Ballard first asserts that the manner in which he was removed from federal custody and taken into state custody was illegal. As a result, he argues that Rhode Island was without jurisdiction to prosecute him, and thus the charges against him should be dismissed with prejudice. It is well settled that “[cjhallenges to a court’s subject-matter jurisdiction can be raised at any point in the proceedings and may not be waived by any party.”
State v. Sivo,
The applicant contends that the writ of habeas corpus and mittimus “served on federal authorities in a federal court building, in which the federal government has exclusive sovereignty [was] not an appropriate legal procedure for transferring physical custody of Ballard from federal to Rhode Island State authorities.” In support of his position, he cites three United States Supreme Court cases:
Robb v. Connolly,
We are of the opinion, however, that applicant’s reliance on the cases cited is misplaced because there was no conflict between the federal and state governments’ asserted authorities in the instant case. The federal government no longer had an interest in exercising authority over applicant when he was released into state custody because, by that time, all federal charges against him had been dismissed. When confronted with a question concerning the transfer of a federal prisoner to state custody with the consent of federal authorities, the United States Supreme Court has held that the state may properly exercise its power to vindicate its own laws.
See Ponzi v. Fessenden,
“One accused of crime has a right to a full and fair trial according to the law of the government whose sovereignty he is alleged to have offended, but he has no more than that. He should not be permitted to use the machinery of one sovereignty to obstruct his trial in the courts of the other, unless the necessary operation of such machinery prevents his having a fair trial. He may not complain if one sovereignty waives its strict right to exclusive custody of him for vindication of its laws in order that the other may also subject him to conviction of crime against it.” Id. at 260,42 S.Ct. 309 (citing In re Andrews,236 F. 300 (D.Vt.1916); United States v. Martin,227 F. 314 (E.D.Pa.1915)).
In the present case, there is no indication that federal authorities challenged the state’s process in asserting custody of Ballard. It was proper, therefore, for applicant to have been released into Rhode Island’s custody, where he had been indicted, because the federal government no longer had an interest in holding him. Thus, we are satisfied that applicant’s argument that he was transferred illegally into state custody is without merit.
B
Confrontation Clause
Mr. Ballard further contends that his right to confrontation under the Sixth Amendment to the United States Constitution was violated because the statement of an out-of-court declarant was read into the record. Specifically, the state was allowed to present the testimony of one Aldo Mer-lino by reading his statement into the record. 4 Merlino was neither called as a wit *269 ness, nor was he ever subjected to cross-examination concerning his statement.

Jury Instruction on Reasonable Doubt
The applicant argues that the trial justice improperly instructed the jury on reasonable doubt, effectively lowering the state’s burden of proof. The trial justice defined “reasonable doubt” as an “actual or a substantial doubt.”
State v. Ballard,
In his first appeal to this Court in 1981, applicant raised, and this Court addressed, this same argument.

Manifestly Excessive Sentence
Mr. Ballard’s final argument is that, although his sentence has been reduced on two separate occasions, it remains “manifestly excessive” and thus violates the Eighth Amendment to the United States Constitution. The applicant’s sentence was reduced initially by the original trial justice.
Ballard III,
The applicant now appeals from his adjusted sentence. But in doing so, Ballard again raises an issue that we previously have reviewed and decided.

Conclusion
For the reasons stated in this opinion, we affirm the judgment and remand the papers in the case to the Superior Court.
Notes
. A more thorough recitation of the facts may be found in
State v. Ballard,
. This Court has stated that it will treat a premature appeal as timely filed.
See, e.g., State v. Diefendeifer,
. Ballard is no longer incarcerated; he was paroled in September 2008. Nevertheless, this Court has previously determined that a party on parole maintains an interest in his or her appeal because a parole violation could result in a return of the party to the Adult Correctional Institutions to complete the remainder of the sentence.
See Morey v. Watt,
. We will assume without deciding that Mr. Merlino's statement was offered for the truth of the matter asserted.
. The Supreme Court held that
Crawford
did not announce a "watershed” rule of criminal procedure, such as could be applied retroactively on collateral review.
See Whorton v. Bockting,
. The doctrine of
res judicata
provides that parties may not relitigate issues that "either were litigated or might have been litigated in a prior action.”
