Birth-Certificate Sex Designations in South Dakota: ARSD 44:09:05:02 Limits Changes to Correction of Errors at Birth; Equal Protection Reviewed Under Rational Basis Absent a Classification

Introduction

In the Matter of the Petition of Sigrid Kristiane Nielsen for an Amended Birth Certificate (2026 S.D. 12) presented the South Dakota Supreme Court with a question at the intersection of administrative law, vital-records regulation, and equal protection doctrine.

The appellant, Sigrid Kristiane Nielsen, a transgender woman born in South Dakota, petitioned the circuit court for an order directing the South Dakota Department of Health (the Department) to amend her birth certificate’s sex designation from male to female. The circuit court denied the request, concluding that the governing administrative rule authorizes only corrections of information that was incorrect when recorded as a “fact of birth,” and that the denial did not violate equal protection. Nielsen appealed on two grounds: (1) the proper interpretation of ARSD 44:09:05:02, and (2) whether denying a sex-designation amendment violates equal protection under the federal and state constitutions.

Summary of the Opinion

The South Dakota Supreme Court affirmed. The Court held:

  1. ARSD 44:09:05:02 permits amendments only to correct “incorrect data” as recorded on the birth certificate—i.e., information that was erroneous at (or shortly after) the time of birth recordation— not to update a correctly recorded sex designation to reflect a later gender identity.
  2. Denying Nielsen’s requested amendment does not violate equal protection because the rule does not classify on the basis of sex or transgender status, does not burden a fundamental right recognized in this context, and is rationally related to legitimate state interests in accurate vital records and the statistical/public-health functions they serve.

A special concurrence underscored a conceptual point: Nielsen framed her request as a correction based on gender, while birth certificates record sex (as distinct from gender identity), and any change to what is recorded (or to the definition of “sex” in this context) is a matter for the Legislature.

Analysis

Precedents Cited

1) Standards of review and interpretive method

  • Puffy's LLC v. Dep't of Health and In re Black Hills Power, Inc.: Cited for the proposition that interpretation and application of statutes and administrative rules are questions of law reviewed de novo. This framing mattered because Nielsen’s appeal was primarily an interpretive dispute over the scope of ARSD 44:09:05:02.
  • State v. Springer (quoting State v. Mesa): Cited to confirm that constitutional claims (including equal protection challenges) are reviewed de novo.
  • Paul Nelson Farm v. S.D. Dep't of Rev. and First Gold, Inc. v. S.D. Dep't of Rev.: Provided the interpretive baseline: give words their plain meaning, read the enactment as a whole, and apply the same canons to administrative rules as to statutes.
  • De Smet Ins. Co. of South Dakota v. Gibson: Supplied a limiting principle—courts should not enlarge clear statutory text—supporting the Court’s refusal to expand ARSD 44:09:05:02 into an authority to update sex designations based on later life changes.

2) Equal protection framework and the role of federal guidance

  • Obergefell v. Hodges: Nielsen relied on Obergefell’s language about liberty and identity to argue that restricting amendment of sex designations disparately affects transgender people and warrants heightened scrutiny. The Court did not accept this as establishing a fundamental right to change a birth certificate’s sex designation.
  • United States v. Skrmetti: This was the opinion’s central modern equal protection reference point. The South Dakota Supreme Court adopted Skrmetti’s approach: determine whether the law classifies by sex or targets a suspect class, and if not, apply rational basis review.
  • Romer v. Evans: Used in Skrmetti (and repeated here) for the general proposition that the Equal Protection Clause coexists with the practical necessity of legislative classifications, and for the rational-basis baseline when no fundamental right or suspect class is implicated.
  • FCC v. Beach Communications, Inc.: Provided the deferential rational-basis formulation: the rule survives if any reasonably conceivable facts supply a rational basis, and if plausible reasons exist, judicial inquiry ends.
  • Washington v. Davis: Anchored the Court’s rejection of a disparate-impact-only theory; disparate impact alone does not establish purposeful discrimination for equal protection purposes.
  • Bostock v. Clayton County: Raised by Nielsen and discussed through Skrmetti’s lens. The Court noted Skrmetti’s hesitation to extend Bostock beyond Title VII and, in any event, found no classification here that turns on sex or transgender status.

3) Birth-certificate amendment litigation in other jurisdictions

  • Ray v. McCloud and F.V. v. Jeppesen: Cited by Nielsen as persuasive authority for the proposition that allowing amendments for some birth-certificate information (e.g., name or parentage) but not sex designation can create unconstitutional disparate treatment. The South Dakota Supreme Court acknowledged these authorities but did not adopt their reasoning.
  • Gore v. Lee: The key persuasive comparator supporting the State’s position. Gore upheld a Tennessee regime similar to South Dakota’s, construing amendments as limited to data that was “factually inaccurate at the time of recordation” and applying rational basis. South Dakota relied on Gore’s articulation of legitimate state interests: public-health tracking, vital statistics reporting, and integrity/accuracy of vital records.
  • L.W. ex rel. Williams v. Skrmetti: Cited within the discussion of Gore to show the Sixth Circuit’s reluctance to treat transgender status as a suspect class, reinforcing the choice of rational basis review.
  • Fowler v. Stitt and Stitt v. Fowler: Included to illustrate a divergent approach: Fowler found purposeful discrimination and sex-based discrimination in Oklahoma’s executive policy, but the U.S. Supreme Court vacated and remanded in light of Skrmetti. The South Dakota Supreme Court treated the vacatur/remand as a cautionary signal to adhere to Skrmetti’s framework.
  • Brandt ex rel. Brandt v. Griffin: Cited for the “invidious discriminatory purpose” concept in equal protection analysis (linked to Skrmetti’s discussion), and used to note Nielsen did not claim ARSD 44:09:05:02 was adopted with discriminatory intent.
  • Dorian v. Johnson: A South Dakota precedent invoked for judicial restraint: where no arbitrary classification is found, the Court need not decide whether heightened scrutiny applies—mirroring the Court’s decision not to decide whether transgender status is a quasi-suspect class.

Legal Reasoning

1) Interpreting ARSD 44:09:05:02 within the vital-records statutory scheme

The Court’s interpretive analysis was structural as much as textual. It began with the statutory premise that a South Dakota birth certificate is designed to register the “facts of birth” within a short time window. The Court connected this purpose to multiple statutes:

  • SDCL 34-25-8: births must be registered, with certificates filed within seven days, and late filings may require additional evidence supporting the facts of birth.
  • SDCL 34-25-9 and SDCL 34-25-9.1: identify who supplies personal and medical information and empower the Department to establish evidence needed to prove facts of birth.
  • SDCL 34-25-51: authorizes Department rulemaking governing amendments.

Against that backdrop, ARSD 44:09:05:02 requires identification of “incorrect data” on the certificate and “correct data as it should appear.” The Court held that the phrase “incorrect data as it is listed” points to a mistake in the original registration of facts, not later developments.

The Court also found confirming evidence of administrative intent in the Department’s amendment form requiring applicants to certify changes are “necessary to reflect the facts as they were at the time of birth.” This moved the Court from merely “plain meaning” into a pragmatic, agency-intent-confirming reading without rewriting the rule.

2) Rejecting the “present-tense” argument

Nielsen argued that “as it should appear” (present tense) implies the regulation contemplates current outward reality. The Court rejected this as overreading grammar: if an original entry was wrong, the corrected entry will appear correctly going forward—without implying that the rule authorizes updates untethered to the facts at birth.

3) Distinguishing name changes from sex designations

A significant move in the opinion was to rebut the analogy to post-birth name changes. The Court pointed to a set of targeted statutes and rules that specifically authorize new certificates or amendments for certain post-birth changes:

  • SDCL 34-25-15 (legitimation/paternity contexts)
  • SDCL 34-25-16.1 (adoption)
  • ARSD 44:09:05:05 (given names)
  • ARSD 44:09:05:12 (surnames)

The Court then emphasized the absence of any comparable South Dakota provision authorizing changes to the sex designation based on later gender identity.

4) “Statistical data” and amendment authority under ARSD 44:09:05:04

The Court reinforced its interpretation by reading ARSD 44:09:05:02 alongside ARSD 44:09:05:04, which restricts amendments to “statistical” items to notifications of error from the person responsible for completing those items. Even though “statistical data” is not defined, the Court reasoned a sex designation “logically” falls within it, whereas a name change does not. This system-level reading supported a narrower “error correction” model for sex entries.

5) Equal protection: no classification, no fundamental right, rational basis suffices

The Court’s equal protection reasoning closely tracked United States v. Skrmetti:

  • No facial classification: ARSD 44:09:05:02 does not mention sex or transgender status and does not limit who may seek amendments. It limits what may be amended—incorrect entries—rather than who may amend.
  • No as-applied sex or transgender classification: The Court treated the rule as operating identically for all applicants: anyone may correct an erroneous sex entry; no one may change a correctly recorded sex entry to reflect later identity. As in Skrmetti’s analysis rejecting “application turns on sex,” the Court focused on the triggering condition (error at recordation), not the applicant’s status.
  • Disparate impact is insufficient: Even if transgender people are uniquely burdened in practice, Washington v. Davis forecloses disparate impact alone as a basis for finding purposeful discrimination. The Court also noted Nielsen did not allege an invidious discriminatory purpose in promulgating the rule.
  • Rational basis: With no fundamental right recognized to amend the sex designation and no suspect-class classification at issue, the Court applied rational basis and upheld the rule as reasonably related to legitimate objectives—particularly the vital-statistics and public-health functions of the registration system.

The Court grounded the “legitimate purpose” analysis in the Department’s statutory role, including the “system of vital registration” definition in SDCL 34-25-1.1(15), which ties the enterprise to “tabulation, analysis, and publication of statistical data” derived from records.

6) The special concurrence: sex vs. gender and institutional competence

Justice Salter’s concurrence sharpened the conceptual frame: Nielsen claimed “incorrect data” based on gender, but the certificate records sex. The concurrence cited Justice Alito’s discussion in United States v. Skrmetti and pointed to a South Dakota statutory definition outside the birth-certificate context—SDCL 34-24-33—defining “sex” in biological terms.

On that view, the petition was not simply a request to “correct” an error under an amendment rule; it was an effort to change what the birth certificate is for (or what “sex” means in this domain). The concurrence treated those as legislative, not judicial, questions.

Impact

  • Administrative-law clarity in South Dakota: The decision establishes a clear interpretive rule that ARSD 44:09:05:02 is an error-correction mechanism tied to the facts at birth, not a general updating tool for later life changes.
  • Constraints on judicial remedies: Petitioners seeking a change to the sex designation on a South Dakota birth certificate face a doctrinal barrier absent proof of original error or new legislative/regulatory authorization.
  • Equal protection litigation posture: The Court’s approach signals that future challenges will likely turn on whether a particular South Dakota policy (or a future enactment) can be shown to create a classification or purposeful discrimination, not merely disparate impact.
  • Legislative invitation: Both the majority and the concurrence effectively place the next move with the Legislature: if the State is to permit sex-designation changes based on gender identity, it will likely require explicit statutory authorization and an accompanying administrative framework that addresses data integrity and statistical/public-health uses.
  • Alignment with Skrmetti-era doctrine: The opinion positions South Dakota’s analysis within the U.S. Supreme Court’s current equal protection methodology, potentially influencing how state courts in similar jurisdictions treat birth-certificate amendment claims.

Complex Concepts Simplified

ARSD vs. SDCL
SDCL are statutes enacted by the Legislature. ARSD are administrative rules adopted by agencies (here, the Department) under statutory authority. Courts interpret both, but agencies may only do what statutes authorize.
“Facts of birth”
Information intended to record conditions existing at the time of birth (as registered shortly after delivery), such as sex as identified at birth, rather than later personal developments.
Facial vs. as-applied challenge
A facial challenge argues a rule is unconstitutional in all its applications. An as-applied challenge argues it is unconstitutional in the particular way it was applied to the plaintiff. Nielsen advanced an as-applied equal protection argument.
Rational basis review
The most deferential form of equal protection review. The government wins if there is any plausible, reasonably conceivable justification for the rule, even if the rule is imperfect or debatable as policy.
Suspect/quasi-suspect class and heightened scrutiny
Some classifications (e.g., race; and in many contexts sex) trigger more demanding review. The Court did not decide whether transgender status is a quasi-suspect class, because it found the rule did not classify on that basis—echoing United States v. Skrmetti.
Disparate impact vs. discriminatory purpose
A rule can affect one group more than another (disparate impact) without being unconstitutional. Under Washington v. Davis, disparate impact alone does not prove the government acted with a discriminatory purpose, which is typically required to establish an equal protection violation for a facially neutral law.

Conclusion

Amended Birth Certificate of Nielsen establishes a firm South Dakota rule: ARSD 44:09:05:02 authorizes amendments to birth certificates to correct errors in the recorded facts of birth, not to update a correctly recorded sex designation to reflect later gender identity. On equal protection, the Court—guided by United States v. Skrmetti—held that because the administrative rule does not classify by sex or transgender status, does not implicate a recognized fundamental right to alter the sex marker, and is rationally related to legitimate vital-statistics and public-health purposes, it is constitutional.

The decision’s practical message is twofold: litigants face a steep constitutional and regulatory hurdle under current law, and any broader accommodation for post-birth changes to sex designation on South Dakota birth certificates is positioned as a legislative policy choice rather than a judicially compelled result.
