STATE OF MAINE

v.

DANIEL GANTNIER

HORTON, A.R.J.

[¶1] Daniel Gantnier appeals from a judgment of conviction for failure to

comply with the Sex Offender Registration and Notification Act of 1999

(“SORNA of 1999”) (Class D), 34-A M.R.S. § 11227(1) (2025), entered by the

trial court (Kennebec County, Davis, C.J.) on Gantnier’s conditional guilty plea.

In 2006, after a jury found him guilty of a sex offense, Gantnier was erroneously

ordered to register under SORNA of 1999 for a term of ten years, when SORNA

of 1999 required persons convicted of that offense to register for life. After

* Justice Horton sat at oral argument and participated in the initial conference while he was an Associate Justice and, as directed and assigned by the Chief Justice, is now participating in this appeal as an Active Retired Justice. 2

Gantnier had completed the ten-year term, the State Bureau of Identification

(SBI) corrected the error and notified him that he must register for life.

Gantnier argues that the retroactively imposed lifetime registration

requirement violates the federal Ex Post Facto Clause, U.S. Const. art. I, § 10, cl.

1.1 We conclude that there is no constitutional impediment to the correction of

Gantnier’s SORNA of 1999 registration obligation and affirm the judgment.

I. BACKGROUND

[¶2] The following facts were found by the court in its April 30, 2024,

order denying Gantnier’s motion to dismiss. See State v. Beaulieu, 2025 ME 4,

¶¶ 2, 9, 331 A.3d 280. The facts are supported by the record. See id.

[¶3] In January 2006, Gantnier was found guilty by a jury of one count of

unlawful sexual contact (Class C), 17-A M.R.S. § 255-A(1)(E) (2025).2 In May

2007, the court (Waldo County, Studstrup, J.) entered a judgment of conviction

and imposed a sentence on Gantnier. According to the judgment and

1 In addition to his argument under the federal Ex Post Facto Clause, Gantnier argues that the State violated the federal Double Jeopardy Clause, U.S. Const. amend. V, by imposing additional burdens under SORNA of 1999 after he was sentenced and after his original ten-year registration term elapsed. However, the Double Jeopardy Clause applies only if a court’s imposition of the original registration obligation was punitive. See State v. George, 1997 ME 2, ¶ 6, 687 A.2d 958; United States v. Ursery, 518 U.S. 267, 274 (1996)). Because we conclude that the court’s imposition of the original registration obligation was not punitive, see infra ¶ 23, we see no basis for Gantnier’s argument under the Double Jeopardy Clause and do not discuss it further.

2 Although this version of 17-A M.R.S. § 255-A(1) incorporates amendments that took effect after

Gantnier was convicted, see, e.g., P.L. 2023, ch. 280, §§ 3, 4 (effective Oct. 25, 2023) (codified at 17-A M.R.S. § 255-A(1)(A), (B) (2025)), the amendments did not affect paragraph E. 3

commitment form, the court sentenced Gantnier to serve thirty months in

prison, with all but thirteen months suspended, followed by four years of

probation.3

[¶4] In a separate section of the judgment and commitment form, the

court checked a box that required Gantnier to register as a sex offender under

SORNA of 1999, 34-A M.R.S. § 11201-11256 (2007).4 Although Gantnier’s

conviction for unlawful sexual contact obligated him by statute to register as a

sex offender for life, see 34-A M.R.S. § 11203(7), (8) (2007), the checked box on

the judgment and commitment form ordered only a ten-year period of

registration. The exact language on the judgment and commitment form reads:

IT IS ORDERED THAT THE DEFENDANT, HAVING BEEN CONVICTED OF AN OFFENSE THAT REQUIRES COMPLIANCE WITH THE SEX OFFENDER REGISTRATION AND NOTIFICATION ACT AS A 10-YEAR REGISTRANT . . . MUST SATISFY ALL REQUIREMENTS IN THE SEX OFFENDER REGISTRATION & NOTIFICATION ACT. THE DEFENDANT MUST SUBMIT TO THE TAKING OF FINGERPRINTS AND A PHOTOGRAPH AS SPECIFIED IN THE NOTICE OF DUTY TO REGISTER.

3 In State v. Gantnier, 2008 ME 40, 942 A.2d 1191, we affirmed Gantnier’s conviction after he challenged the court’s jury instructions on appeal.

4 We cite the statutes in effect when Gantnier was ordered to register as a sex offender in 2007 but note that amendments enacted after that time generally do not affect the outcome of this appeal. See, e.g., P.L. 2015, ch. 280, § 6 (effective Oct. 15, 2015) (codified at 34-A M.R.S. § 11222(4-C) (2025)). As one important exception, a 2009 amendment to SORNA of 1999 allowing for the correction of erroneously assigned registration terms is relevant here because Gantnier challenges whether this amendment retroactively applies to erroneous registration terms assigned before the amendment took effect. See P.L. 2009, ch. 365, §§ B-15, B-22 (effective Sept. 12, 2009, retroactive to Jan. 1, 1982) (codified at 34-A M.R.S. § 11222(1) (2025)). 4

(Citation omitted.)

[¶5] On February 15, 2019, Gantnier received a letter from the Maine

Department of Public Safety informing him that, pursuant to a 2009

amendment to SORNA, see P.L. 2009, ch. 365, §§ B-15, B-22 (effective Sept. 12,

2009, retroactive to Jan. 1, 1982) (codified at 34-A M.R.S. § 11222(1) (2025)),

the SBI had corrected his registration term to extend for life. After receiving

the letter, Gantnier did not comply with sex offender registration requirements.

In 2022, the State charged Gantnier by complaint with failure to comply with

SORNA of 1999 (Class D), 34-A M.R.S. § 11227(1). Gantnier initially pleaded

not guilty. On June 28, 2023, he filed a motion to dismiss the complaint.

[¶6] In support of his motion, Gantnier argued that the imposition of a

lifetime registration requirement under SORNA of 1999 violated the ex post

facto provisions of the United States and Maine Constitutions, U.S. Const. art. I,

§ 10, cl. 1; Me. Const. art. I, § 11,5 because the State retroactively enhanced a

portion of his sentence by applying the 2009 amendment of 34-A M.R.S.

§ 11222(1) to his case. Citing State v. Johnson, 2006 ME 35, ¶ 14, 894 A.2d 489,

5 Although Gantnier has contended that the retroactive modification of his SORNA of 1999 registration obligation violates the Maine Constitution’s Ex Post Facto Clause, we do not apply the primacy approach to review the state constitutional issue because Gantnier did not present “an independent analysis of [article 1, section 11] of the Maine Constitution.” State v. Norris, 2023 ME 60, ¶ 52, 302 A.3d 1. 5

Gantnier further stressed that the State failed to file a timely motion under

M.R.U. Crim. P. 35(a) to correct an illegal sentence, which he viewed as the

State’s only available remedy.

[¶7] The court (Daniel Mitchell, J.) held a hearing on Gantnier’s motion to

dismiss and denied the motion in a written order entered on April 30, 2024. As

to Gantnier’s argument under the federal Ex Post Facto Clause, the court

referenced our decisions in State v. Letalien, 2009 ME 130, ¶¶ 61-63, 985 A.2d

4, and State v. Proctor, 2020 ME 107, ¶ 16, 237 A.3d 896, and reasoned that the
