This is an appeal from the entry of a final order by the Superior Court, in and for New Castle County. The plaintiffs-appellants, David R. DiStefano (“DiStefano”) and James Stewart (“Stewart”), both of whom are prisoners at the Delaware Correctional Center, filed a civil petition for a writ of mandamus and declaratory relief. Their complaint challenged the validity, scope, and application to them of the February 21, 1986 amendment to 11 Del.C. § 6537, codified as a new subsection (b) of that statute. That amendment limited the authority of the Department of Correction to permit certain prisoners, including DiStefano and Stewart, to participate in any program or to engage in any visitation beyond the confines of a secured penal institution. The defendant-appellee, Robert J. Watson, Commissioner of the Delaware Department of Correction (“Watson”), filed a motion to dismiss the complaint for failure to state a claim upon which relief could be granted. The Superi- or Court granted Watson’s motion, which it treated as a motion for summary judgment.
DiStefano and Stewart have appealed from the Superior Court’s decision on the following grounds: (1) the General Assembly did not intend 11 Del.C. § 6537(b) to operate retrospectively; (2) the General Assembly did not intend the provisions of 11 Del.C. § 6537(b) to apply to persons who are eligible for parole or conditional release in less than 10 years; (3) the application of 11 Del. C. § 6537(b) to them would violate the ex post facto prohibition of the United States Constitution; and (4) the application of 11 Del.C. § 6537(b) to them would violate the substantive due process guarantees of both the United States Constitution and the Delaware Constitution. We have concluded that none of the claims raised by DiStefano and Stewart are meritorious.
Facts
DiStefano was convicted in the New Castle County Superior Court on August 11, 1982, of Rape in the Second Degree in violation of 11 Del.C. § 763 (repealed in 1986), a Class B felony, and Kidnapping in the Second Degree in violation of 11 Del. C. § 783, also a Class B felony, both offenses arising out of an incident occurring on May 5, 1982. On October 8, 1982, DiStefano was sentenced to a fifteen-year prison term for the rape, beginning August 11, 1982, suspended after ten years for ten years of probation, and to a consecutive ten-year prison term for the kidnapping, suspended after two years for ten years of additional probation. DiStefano has remained in the custody of the Department of Correction since the commencement of the aforementioned sentences. He became eligible for parole on November 4, 1985. In December of 1985, his application for parole was considered and denied. Thereafter, on June 5, 1986, DiStefano was placed on work release at the Plummer Center by the Department of Correction.
Stewart was convicted in the New Castle County Superior Court on December 5, 1978, of Attempted Rape in the First Degree in violation of 11 Del.C. §§ 764 (repealed in 1986) and 531, a Class A felony; Robbery in the First Degree in violation of 11 Del. C. § 832, a Class B felony; Possession of a Deadly Weapon During the Commission of a Felony in violation of 11 Del. C. § 1447, also a Class B felony; Burglary in the Second Degree in violation of 11 Del. C. § 825, a Class C felony; Kidnapping in the Second Degree in violation of 11 Del.C. § 783, a Class B felony; and Offensive Touching in violation of 11 Del.C. § 601, a Class B misdemeanor. On February 14, 1979, Stewart was sentenced to serve consecutive prison terms of ten years for the rape, three years without parole for the robbery, five years without parole for the *3weapons offense, two years for the burglary, three years for the kidnapping and six months for the offensive touching, for a total term of twenty-three years and six months, beginning May 26, 1978. Stewart has also remained in the custody of the Department of Correction since the commencement of his sentences. During the period of his incarceration through 1985, Stewart was permitted to leave prison for several home visits under the Department of Correction’s furlough/special visit program. On December 12, 1986, after serving eight years of his sentence, Stewart became eligible for parole.
On February 21, 1986, 11 Del.C. § 6537(b) became effective. It provides that:
Notwithstanding any other provision of this section or title to the contrary, the Department [of Correction] shall have no authority to place any person convicted of a class A felony, during the first 10 years of said sentence, or of any class A or B felony sex offense, during the first 10 years of said sentence, or any person sentenced pursuant to See. 4204(k) of this title on any program or status beyond the confines of a secured institution to which he or she must be classified. In the event of the death or serious illness of an immediate family member, or a similar emergency, the Commissioner of Correction shall have the authority to permit such person an escorted visit within the State under strict security. In the event that there exists extraordinary circumstances, excluding emergency situations authorized by the Commissioner pursuant to the previous sentence of this subsection, and the Commissioner of Correction agrees, he may petition the Superior Court, after notice to the Attorney General, for permission to exempt an individual from the limitations contained in this section.
11 Del.C. § 6537(b). Following the enactment of Section 6537(b), Department of Correction officials continued to permit prisoners sentenced for Class A felonies or Class B felony sex offenses1 committed prior to the effective date of the statute, including DiStefano and Stewart, to participate in the departmental community-release programs and other activities outside the confines of a secured institution, even though they had not yet served 10 years of their sentence.
The Attorney General of the State of Delaware was requested to render an opinion concerning the Department of Correction’s interpretation and application of 11 Del.C. § 6537(b). In December of 1986, the Attorney General opined that the statute, as amended, did apply to persons whose offenses pre-dated its enactment and also applied to persons whose sentences for the offenses were less than ten years. Thereafter, the Department of Correction notified all Class A felony offenders and Class B felony sex offenders, including DiStefano and Stewart, that Section 6537(b) precludes their participation in any community-release program or “outside status” activities, until they have served 10 years on their terms, regardless of when their offenses were committed or the length of their sentence. Accordingly, DiStefano’s work-release status has been revoked and Stewart is no longer considered eligible for home visits.
Legislative Intent and Statutory Construction
DiStefano and Stewart argue that 11 DeLC. § 6537(b) is ambiguous in two respects. First, they argue that it is not clear that the General Assembly intended *4the statute to apply to offenders who were convicted and sentenced prior to its enactment date, an application which DiStefano and Stewart characterize as retroactive.2 Second, DiStefano and Stewart argue that it is not clear that the General Assembly intended the statute to apply to persons who, by the terms of their sentence, are eligible for parole or conditional release in less than 10 years.
A statute is ambiguous if it is reasonably susceptible of different conclusions or interpretations. Coastal Barge Corp. v. Coastal Zone Indus. Control Bd., Del. Supr., 492 A.2d 1242, 1246 (1985). “Ambiguity may also arise from the fact that giving a literal interpretation to words of the statute would lead to such unreasonable or absurd consequences as to compel a conviction that they could not have been intended by the legislature.” Id. “If a statute is ambiguous, a court must resolve the ambiguity by reconciling its language with the legislative intent.” Daniels v. State, Del.Supr., 538 A.2d 1104, 1109 (1988). However, if a statute is unambiguous, and an application of the literal meaning of its words would not be absurd or unreasonable, there is no legal basis for an interpretation of those words by the court. Id. In such a situation, the words of the statute must be given their literal meaning. Coastal Barge Corp. v. Coastal Zone Indus. Control Bd., 492 A.2d at 1246.
In this case, the first alleged ambiguity is with respect to the persons affected by the statute. The pertinent part of Section 6537(b) reads:
[T]he Department shall have no authority to place any person convicted of [the offenses listed] on any program or status beyond the confines of a secured institution to which he or she must be classified.
11 Del.C. § 6537(b). This language is not reasonably susceptible to different conclusions or interpretations. This language makes the statute applicable to any person convicted of the offenses listed. There are no exceptions. DiStefano and Stewart were both convicted of offenses listed in the statute. They are included within the term “any person” in the statute.
The second ambiguity alleged by DiStefano and Stewart relates to the application of Section 6537(b) to any person convicted of the offenses listed, regardless of the length of the imposed sentence. The pertinent part of the statute states that it shall apply to such persons “during the first 10 years of said sentence.” 11 Del.C. § 6537(b). This language in the statute applies to two identifiable categories of inmates, those convicted of a Class A felony or a Class B felony sex offense. The statute makes no exceptions for persons within those categories, who were sentenced to be incarcerated for less than 10 years.
We find that 11 Del.C. § 6537(b) is unambiguous. There is no basis for statutory construction or interpretation. Chrysler Corp. v. State, 457 A.2d at 348. The Superior Court’s task was to apply the literal meaning of the words in the statute to the facts which were before it. Coastal Barge Corp. v. Coastal Zone Indus. Control Bd., 492 A.2d at 1246. We affirm the finding by the Superior Court that the provisions of Section 6537(b) apply to DiStefano and Stewart.
We also affirm the Superior Court’s conclusion that the application of Section 6537(b) to DiStefano and Stewart is not unreasonable or absurd. Id. The admitted purpose of the General Assembly, in passing Section 6537(b), was to limit the Department of Correction’s discretion in allowing contacts outside of a secured institution by a certain categories of persons. DiStefano and Watson are such persons.
*5 Ex Post Facto
DiStefano’s and Stewart’s next argument is that if 11 Del.C. § 6537(b) is unambiguous and applies to them, it violates the ex post facto clauses of article I, §§ 9 and 10 of the United States Constitution. The ex post facto prohibition precludes Congress or the states from enacting any law “which imposes a punishment for an act which was not punishable at the time it was committed; or imposes additional punishment to that then prescribed.” Weaver v. Graham, 450 U.S. 24, 28, 101 S.Ct. 960, 964, 67 L.Ed.2d 17 (1981) (quoting Cummings v. Missouri, 4 Wall. 277, 325-326, 18 L.Ed. 356 (1867)).3 DiStefano and Stewart argue that the enactment of 11 Del-C. § 6537(b) has enhanced their punishment by limiting or precluding their participation in activities outside of a secured penal institution.
A law violates the ex post facto prohibition, when it “changes the punishment, and inflicts a greater punishment, than the law annexed to the crime, when committed.” Calder v. Bull, 3 U.S. 386, 390, 1 L.Ed. 648 (1798) (emphasis added). The law annexed to the crime has been construed to mean that law which is “an integral part of the sentencing procedure.” Milhouse v. Levi, 548 F.2d 357, 364 (D.C.Cir.1976). In Mil-house, the court held that eligibility for a furlough program, unlike eligibility for parole, was not an integral part of the sentencing procedure; that is, not part of the law annexed to the crime, but rather “[i]t is an internal rehabilitational program the denial of which cannot be said to be an element of the punishment attached to an inmate’s initial conviction.” Id.
The reasoning of Milhouse has been specifically applied to Section 6537(b) by the United States District Court of Delaware. Marvel v. Ryan, D.Del., C.A. No. 87-268 MMS, Schwartz, C.J. (Aug. 13, 1987). In Marvel, as a result of the enactment of Section 6537(b), a special visit was denied to a Class B felony sex offender, who had been sentenced prior to the effective date of the statute. The United States District Court held that Delaware’s release programs were not an element of punishment attached to an inmate’s initial conviction.4 Id. Therefore, in Marvel, the United States District Court rejected an ex post facto challenge to 11 Del.C. § 6537(b). Id. We have reached the same conclusion.5
*6Section 6537(b) “does not affect the maximum or minimum prison sentence a court may impose, the point at which the prisoner becomes eligible for parole, or his mandatory release date.” Francis v. Fox, 838 F.2d 1147, 1150 (11th Cir.1988) (citing Dufresne v. Baer, 744 F.2d 1543, 1550 (11th Cir.1984), cert. denied, 474 U.S. 817, 106 S.Ct. 61, 88 L.Ed.2d 49 (1985)). The Delaware statute, like the one addressed in Milhouse, is an administrative law which regulates the Department of Correction's internal affairs, and is not a law annexed to the crime. We affirm the decision of the Superior Court in this case, which held that 11 Del.C. § 6537(b) does not violate the federal constitutional prohibition against the enactment of the ex post facto laws.
Substantive Due Process
The United States Constitution prohibits governmental deprivations of life, liberty or property without due process of law. U.S. Const, amend. Y, XIV. “[A person] is not wholly stripped of constitutional protections when he is imprisoned for a crime.” Wolff v. McDonnell, 418 U.S. 539, 555, 94 S.Ct. 2963, 2974, 41 L.Ed.2d 935 (1974). See generally Greenholtz v. Inmates of the Nebraska Penal & Correctional Complex, 442 U.S. 1, 7, 99 S.Ct. 2100, 2103-04, 60 L.Ed.2d 668 (1979). DiStefano and Stewart’s final argument is that if 11 Del. C. § 6537(b) does not violate the ex post facto prohibitions, it does violate their right to substantive due process,6 which is guaranteed under both the United States Constitution and the Delaware Constitution.7
The protection afforded by the guarantee of substantive due process interposes a bar to legislation that “manifests a patently arbitrary classification, utterly lacking in rational justification.” Flemming v. Nestor, 363 U.S. 603, 611, 80 S.Ct. 1367, 1373, 4 L.Ed.2d 1435 (1960). Legislation, like 11 Del.C. § 6537(b), regulating what is considered to be an injurious practice within a state, is presumed constitutional “unless ... it is of such a character as to preclude the assumption that it rests upon some rational basis within the knowledge and experience of the legislators.” United States v. Carolene Products Co., 304 U.S. 144, 152, 58 S.Ct. 778, 783, 82 L.Ed. 1234 (1938) (footnote omitted).8 Therefore, a *7substantive due process analysis of governmental action in the form of legislation, requires the court to determine whether there are any facts, either known or which could reasonably be assumed, which affords support for the legislation. United States v. Carolene Products Co., 304 U.S. at 154, 58 S.Ct. at 784-85; Cheswold Volunteer Fire Co. v. Lambertson Const. Co., 462 A.2d at 423-24.
Stewart and DiStefano argue that no rational basis exists, or can be imagined, for the restrictions imposed by 11 Del.C. § 6537(b) on all persons convicted of a Class A felony or a Class B felony sex offense, in contrast to those persons who have committed other serious offenses. However, we find that there are facts which can be reasonably assumed to afford support for the decision of the General Assembly to enact legislation restricting the ability of persons who are convicted of a Class A felony or Class B felony sex offense from interacting with the public, during the first ten years of their confinement. We also find that the General Assembly’s decision not to make 11 Del.C. § 6537(b) all inclusive, by extending its restrictions to every category of criminal conviction to which they might reasonably have been applied, is not determinative for purposes of substantive due process. Flemming v. Nestor, 363 U.S. 603, 612, 80 S.Ct. 1367, 1373, 4 L.Ed.2d 1435 (1960).
The Due Process Clause does not require a state to relieve an inmate from having to serve a valid sentence in a confined setting. Greenholtz v. Inmates of the Nebraska Penal & Correctional Complex, 442 U.S. 1, 99 S.Ct. 2100, 60 L.Ed.2d 668 (1979). Thus, if a state desires to have all or some of its criminal sentences served completely within the confines of a secured penal institution, the Constitution does not require the state to abandon that goal by adopting a system of early release. Id. “[TJhere is no constitutional or inherent right of a convicted person to be conditionally released before the expiration of a valid sentence.” Id. at 7, 99 S.Ct. at 2104.
The guarantee of substantive due process is only violated when the government engages in actions which “offend those canons of decency and fairness which express the notions of justice of English-speaking peoples toward those charged with the most heinous offenses.” Malinski v. New York, 324 U.S. 401, 416-17, 65 S.Ct. 781, 788-89, 89 L.Ed. 1029 (1945). Section 6537(b) is not such a statute. In extraordinary circumstances, the Commissioner of Corrections may petition the Superior Court, after notice to the Attorney General, for permission to exempt an individual, who has been convicted of a Class A felony or a Class B sex offense, from its limitations. 11 Del.C. § 6537(b). We affirm the Superior Court’s conclusion that there has been no violation of DiStefano’s or Stewart’s right to substantive due process under either the United States Constitution or the Delaware Constitution.
Conclusion
All the rulings of the Superior Court, which led to the judgment that dismissed the complaint filed by DiStefano and Stewart, are found to be correct. Therefore, the judgment of the Superior Court is AFFIRMED.
