[¶ 2] In 1992, a jury found Norman guilty of class AA felony murder for killing his wife Pamela Norman.
See State v. Norman,
[¶ 3] The Legislature enacted N.D.C.C. ch. 31-13 in 1995 to provide for DNA testing and a DNA data base. See 1995 Sess. Laws ch. 325. As originally enacted, N.D.C.C. § 31-13-03 limited DNA testing to individuals convicted of certain sexual offenses or attempted sexual offenses. The Legislature amended § 31-13-03 in 2001 to expand DNA testing to include certain nonsexual felony offenses. See 2001 N.D. Sess. Laws ch. 302, § 1. The 2001 version of § 31-13-03 (emphasis added), states:
The court shall order any person convicted on or after August 1, 1995, of any sexual offense or attempted sexual offense in violation of sections 12.1-20-03, 12.1-20-03.1, 12.1-20-04, 12.1-20-05, 12.1-20-06, subdivision e or f of subsection 1 of section 12.1-20-07, or section 12.1-20-11 or any other offense when the court finds at sentencing that the person engaged in a nonconsensual sexual act or sexual contact with another person during, in the course of, or as a result of, the offense and any person who is in the custody of the department after July 31, 1995, as a result of a conviction of one of these offenses to have a sample of blood.or other body fluids taken by the department for DNA law enforcement identification purposes and inclusion in law enforcement identification data bases. The court shall order any person convicted after July 31, 2001, of a felony offense contained in chapter 12.1-16, 12.1-17, or 12.1-18, section 12.1-22-01, or chapter 12.1-27.2 and any person who is in the custody of the department after July 31, 2001, as a result of a conviction for one of these offenses to have a sample of blood or other body fluids taken by the department for DNA law enforcement identification purposes and inclusion in the law enforcement identification data bases. Notwithstanding any other provision of law, if the sentencing court has not previously ordered a sample of blood or other body fluids to be taken, the court retains jurisdiction and authority to enter an order that the convicted person provide a sample of blood or other body fluids as required by this section. Any person convicted after July 31, 1995, who is not sentenced to a term of confinement shall provide a sample of blood or other body fluids as a condition of the sentence or probation at a time and place specified by the sentencing court. The sentencing court shall assess the cost of the procedure against the person being tested. The department shall collect the cost of the procedure from the person being tested and transfer the amount collected to the state department of health for deposit in the general fund. 1
*552 Norman’s conviction for class AA felony-murder is a felony offense contained in N.D.C.C. ch. 12.1-16.
[¶ 4] In December 2001, the State moved the district court to order Norman provide a DNA sample under N.D.C.C. § 31-13-03. Without a hearing or providing him notice, the court ordered Norman to “provide a sample of blood and body fluids ... for DNA law enforcement identification purposes and inclusion in law enforcement identification data bases in accordance with the provisions of N.D.C.C. ch. 31-13.” In practice, DNA samples in North Dakota are obtained using an oral swab.
[¶ 5] Norman moved to quash the order and for an injunction to stay the collection of the DNA sample. Upon Norman’s request, the district court appointed an attorney to represent him. The court postponed the testing until it ruled on his motion and ordered no sanctions be taken against him. Norman’s present counsel is the fourth appointed attorney in this case; the other three attorneys were allowed to withdraw because of conflicts.
[¶ 6] Among his many arguments against providing a DNA sample, Norman challenged the constitutionality of § 31-13-03 on ex post facto grounds; therefore, the Attorney General responded by filing a brief defending the statute’s constitutionality. Following a June 2002 hearing, the district court issued an order denying Norman’s earlier motion to quash the order which required him to provide a DNA sample. The court determined § 31-13-03 was retroactive and Norman was subject to its requirements. Furthermore, the appointment of counsel and the hearing had satisfied his rights to due process. Norman moved to stay the collection of the DNA sample pending this appeal, and the district court granted his motion.
[¶ 7] On appeal, Norman challenges N.D.C.C. § 31-13-03 on multiple grounds: the district court erred in finding § 31-13-03 is retroactive and in finding Norman’s 1992 murder conviction and status as an inmate require he provide a DNA sample; section 31-13-03 is an impermissible ex post facto law; the statute violates his Fifth Amendment right against self-incrimination; and the court erred in finding Norman would not suffer new legal consequences by refusing to provide a DNA sample.

Mass. 336,
[¶ 9] Challengers to DNA data base statutes have raised issues such as cruel and unusual punishment, equal protection, prohibition against ex post facto laws, free exercise of religion, procedural and substantive due process, right to privacy, the Fifth Amendment right against self-incrimination, separation of powers, and the Fourth Amendment right against unreasonable search and seizure.

State v. Leppert,
Ill
A
[¶ 11] Norman argues the district court erred in finding N.D.C.C. § 31-13-03 is retroactive. He asserts a plain reading of this portion of the statute demonstrates § 31-13-03 is clearly not retroactive:
The court shall order any person convicted after July 31, 2001, of a felony offense contained in chapter 12.1-16, 12.1-17, or 12.1-18, section 12.1-22-01, or chapter 12.1-27.2 and any person who is in the custody of the department after July 31, 2001, as a result of a conviction for one of these offenses....
Thus, Norman asserts § 31-13-03 applies only to a person who was both convicted after July 31, 2001, and in departmental custody after July 31, 2001. Because he was not convicted after July 31, 2001, the statute should not apply to him. If the statute was intended to specify two separate categories of people, punctuation, such as a comma, would have been inserted before the conjunction “and.”
[¶ 12] The State asserts N.D.C.C. § 31-13-03, by its clear and unambiguous language, is retroactive. As the Attorney General noted in its amicus curiae brief and the State asserted at oral argument, the use of the subject “any person” twice lends to an interpretation that two separate categories of people were intended by the statute: (1) individuals convicted after July 31, 2001, of the enumerated offenses, and (2) individuals in the Department’s custody after July 31, 2001, because of a conviction for those offenses. If only one category of people was intended, repetition of the subject “any person” would be unnecessary.
[¶ 13] Under N.D.C.C. § 1-02-10, “[n]o part of this code is retroactive unless it is expressly declared to be so.” A statute need not explicitly use the term “retroactive” for it to be applied to facts occurring before the effective date of the statute.
Overboe v. Farm, Credit Servs.,
[¶ 14] As we have previously stated:
The interpretation of a statute is fully reviewable on appeal. Our primary objective in construing a statute is to ascertain the intent of the Legislature by looking at the language of the statute itself and giving it its plain, ordinary, and commonly understood meaning. Although courts may resort to extrinsic aids to interpret a statute if it is ambiguous, we look first to the statutory language, and if the language is clear and unambiguous, the legislative intent is presumed clear from the face of the statute.
Overboe,
[¶ 15] Both parties assert § 31-13-03, on its face, clearly supports their respective positions. After examining the language of § 31-13-03, giving it its plain, ordinary, and commonly understood meaning, we agree the repeated use of the subject “any person” supports the conclusion that the Legislature intended the provision to include two separate categories of individuals: “The court shall order
any person
convicted after July 31, 2001, of a felony offense contained in chapter 12.1-16, 12.1-17, or 12.1-18, section 12.1-22-01, or chapter 12.1-27.2
and any person
who is in the custody of the department after July 31, 2001 ...” N.D.C.C. § 31-13-03 (emphasis added). Although this interpretation seems most reasonable from a plain reading of the statute, Norman’s interpretation is not untenable.
Cf. Hilton v. N.D. Educ. Ass’n,
[¶ 16] The entire legislative history of N.D.C.C. § 31-13-03, as amended in 2001, demonstrates cost was an important consideration in expanding the offenses included in the data base. The original bill would have applied to a greater number of felony offenses. Hearing on H.B. 1208 Before the Senate Judiciary Comm., 57th Leg. Assem. (Mar. 5, 2001) (testimony of Representative Lawrence Klemin). However, due to the costs of such testing, the final bill was limited to testing individuals convicted of the enumerated, primarily violent, felony offenses.
[¶ 17] Although the projected fiscal effects of this bill changed over the 2001 legislative session, the estimated number of offenders and cost for the first biennium were always greater than the estimated number of offenders and cost in the subsequent biennium. The Director of the Crime Laboratory Division of the Department of Health explained this “drop in numbers” resulted from “having to profile all current offenders in custody as of July 31, 2000(sic). That would get us caught up. It is estimated that we would have another 550 people to profile after that every year.” Hearing on H.B. 1208 Before the House Judiciary Comm., 57th *555 Leg. Assem. (Jan. 24, 2001) (testimony of Kenan Bullinger, Crime Laboratory Director). The bill’s primary sponsor also explained why the number of individuals to be tested was greater the first year, compared to subsequent years, stating “[t]he reason the number is higher the first year is to take into account the present prison population and the present parole/probation population.” Hearing on H.B. 1208 Before the House Appropriations Comm., 57th Leg. Assem. (Feb. 14, 2001) (memo of Representative Lawrence Klemin).
[¶ 18] As noted, the cost of this amendment was a significant concern. To decrease the ultimate cost of the testing, the Legislature decreased the enumerated offenses the DNA testing statute would encompass. Although not testing “the present prison population and the present parole/probation population” also would have decreased costs, the legislative history does not indicate consideration of such an alternative proposal.
[¶ 19] The underlying purpose of this bill, reflected in the legislative history, demonstrates the Legislature’s intent to further expand the DNA data base. The goals were to increase success rates of solving crimes in North Dakota and other states, exonerate innocent suspects, and aid in identifying those who commit future crimes. Hearing on H.B. 1208 Before the House Judiciary Comm., 57th Leg. As-sem. (Jan. 24, 2001) (testimony of Representative Lawrence Klemin). These goals would be further advanced by including those inmates already incarcerated for the newly included offenses. Therefore, after reviewing the legislative history of N.D.C.C. § 31-13-03, we conclude the Legislature intended the expanded DNA testing to include individuals in the custody of the department after July 31, 2001, as a result of a conviction for one of the specified offenses.
[¶ 20] Furthermore, we conclude the court had no discretion in ordering Norman to provide a sample. Section 31-13-03 states “[t]he court shall order....” As we have previously stated:
Ordinarily, the word “shall” in a statute creates a mandatory duty. The word “shall” is “generally imperative or mandatory ... excluding the idea of discretion, and ... operating to impose a duty.” Where necessary to effect the intent of the legislature, however, the word “shall” will be interpreted as creating a duty that is merely directory. If the duty prescribed in the statute is essential to its main objectives, the word “shall” is to be construed as creating a mandatory duty.
Sweeney v. Sweeney,

[¶21] Norman’s statement of the issues also contains an ex post facto challenge to N.D.C.C. § 31-13-03. We have stated the Legislature may apply statutes retroactively unless doing so would result in ex post facto application.
State v. Shafer-Imhoff,
[¶ 22] Norman purports to raise a generalized ex post facto challenge to N.D.C.C. § 31-13-03, but he fails to develop this argument or articulate this assertion from his retroactivity argument. This Court will only decide those issues which have been thoroughly briefed and argued.
Olander Contr. Co. v. Gail Wachter Invs.,
[¶ 23] However, our research has revealed multiple cases, not cited in Norman’s appellate brief, in which courts have addressed and rejected ex post facto challenges to DNA testing statutes. For example, in
Rise v. Oregon,
[¶ 24] Similarly, in
Shaffer v. Saffle,
[¶ 25] Numerous other courts have followed similar reasoning and rejected ex post facto challenges.
See, e.g., Gilbert v. Peters,
C
[¶ 26] Norman also contends the DNA testing violates his Fifth Amendment right against self-incrimination. In
Schmerber v. California,
[¶ 27] Other courts have rejected claims which allege requiring an individual to provide a DNA sample amounts to compulsory self-incrimination.
See Shaffer v. Saffle,
D
[¶ 28] Norman asserts the district court erred in finding he would not suffer negative consequences by refusing to provide a DNA sample. Norman claims by failing to submit a sample he will be held beyond his release date. He cites
Jones v. Murray,
[¶ 29] When Norman first refused to submit to testing, the director of prisons division did send him written notice, stating Norman’s failure to comply would “result in disciplinary action being taken, up to and including loss of job.” Norman did not address this type of negative consequence in his appellate brief. Due to the district court’s order, no sanctions were imposed on Norman. Furthermore, in challenges to DNA testing schemes, other courts have concluded disciplinary actions as a result of testing noncompliance are part of prison administration and regula
*558
tion.
See, e.g., Gilbert,
It is precisely because reasonable prison regulations, and subsequent punishment for infractions thereof, are contemplated as part of the sentence of every prisoner, that they do not constitute additional punishment and are not classified as ex post facto. Moreover, since a prisoner’s original sentence does not embrace a right to one set of regulations over another, reasonable amendments, too, fall within the anticipated sentence of every inmate. We therefore conclude that neither [the] blood-testing requirement, itself, nor the infliction of punishment within the terms of the prisoners’ original sentence for a violation of the requirement, is ex post facto. (citations omitted).
Jones, at 309-10;
see also Ewell,
[¶ 30] We conclude Norman has not supported his claim that the district court erred in finding he would not suffer negative consequences for failing to submit, in the record or his brief.
IV
[¶ 31] We hold N.D.C.C. § 31-13-03 applies (1) to a person convicted after July 31, 2001, of a felony offense contained in chapter 12.1-16, 12.1-17, or 12.1-18, section 12.1-22-01, or chapter 12.1-27.2; and (2) to a person who is in the custody of the department after July 31, 2001, as a result of a conviction for one of these offenses. Because we have rejected the other issues raised by Norman, we affirm the district court order denying Norman’s motion to quash the earlier court order which required him to provide a DNA sample.
Notes
. In 2003, the Legislature amended the portion of § 31-13-03 at issue in this case to read:
The court shall order any person convicted after July 31, 2001, of a felony offense contained in chapter 12.1-16, 12.1-17, or 12.1- *552 18, section 12.1-22-01, or chapter 12.1— 27.2 or any person who is in the custody of the department after July 31, 2001, as a result of a conviction for one of these offenses to have a sample of blood or other body fluids taken by the department for DNA law enforcement identification purposes and inclusion in the law enforcement identification data bases.
HB 1235, 58th Leg. Assem., Reg. Sess. (N.D. 2003) (emphasis added).
. The states’ statutory schemes vary in their structure and the included offenses which mandate DNA testing. See, e.g., Alaska Stat. § 44.41.035 (establishing DNA testing for individuals convicted of crimes against a person, burglary, and a felony attempt to commit burglary, including minors 16 years of age or older adjudicated as a delinquent for an act that would be one of those crimes if committed by an adult); Cal.Penal Code §§ 295, 296 (including offenders of enumerated crimes found not guilty by reason of insanity); Conn. Gen.Stat. § 54-102g (limiting DNA testing to certain sexual offenders); Minn.Stat. § 609.117 (including multiple offenses from murder and assault to false imprisonment and indecent exposure); Miss.Code Ann. § 45-33-37 (including only sexual offenders); Mont. Code Ann. § 44-6-102 (including felony offenders and youths found to have committed a sexual or violent offense).
