Due Process Limits Article 198’s One-Year Peremption When the Child Was Born and Raised in the Biological Father’s Family Unit

I. Introduction

In Sarah Allen Davidson v. Terrance Hardy (La. 3/6/2026), the Supreme Court of Louisiana reviewed a juvenile court ruling declaring La. C.C. art. 198 unconstitutional as applied to a putative biological father who filed to establish paternity more than one year after the child’s birth. The dispute arose because the child, Z.H., was born within 300 days of the mother’s divorce, triggering the marital presumption under La. C.C. art. 185 that the mother’s former husband (Steven Allen) was the child’s presumed father.

The central issue was whether Article 198’s one-year peremptive deadline (for a biological father’s paternity action when another man is presumed the father) can constitutionally bar a claim where the child was not born into (and never lived in) an intact family unit with the presumed father, and where the biological father promptly acknowledged and actually parented the child early in life.

The parties were:

  • Sarah Allen Davidson (mother; relator seeking to enforce Article 198’s peremptive bar), and
  • Terrance Hardy (putative biological father; respondent challenging Article 198 as unconstitutional as applied).

II. Summary of the Opinion

Justice Guidry, writing for the majority, affirmed the trial court. The Court held that La. C.C. art. 198 is unconstitutional as applied under these facts because it unconstitutionally limits Hardy’s constitutionally protected liberty interest in parenting and deprives him of due process under the Louisiana and United States Constitutions.

The Court distinguished Kinnett v. Kinnett, where Article 198 was upheld as applied, emphasizing that—unlike Kinnett—Z.H. was conceived and born into the biological father’s household and had no meaningful relationship with the presumed father.

Chief Justice Weimer and Justice McCallum dissented; Justice Pro Tempore Penzato dissented with reasons. The dissents argued that the legislature drew a constitutionally permissible bright-line rule in Article 198, that the father forfeited a statutorily granted right by missing the deadline, and that courts should not create case-by-case exceptions through “as applied” invalidations.

III. Analysis

A. Precedents Cited

1. The Louisiana framework for parental liberty interests and due process

  • State of Louisiana in the Interest of J.A. — Cited for the proposition that parents have a “natural, fundamental liberty interest” in the “continuing companionship, care, custody, and management” of their children. The majority uses this to anchor the analysis in recognized constitutional doctrine rather than treating the claim as merely statutory.
  • In re Adoption of B.G.S. — Cited for the principle that once a person has a constitutionally cognizable liberty interest, due process protections apply, and (importantly here) that a biological father who “grasps the opportunity” and accepts responsibility may acquire an interest “worthy of constitutional protection.”
  • State in Interest of D.T. — Cited for the de novo standard of review applicable to constitutional determinations.

2. U.S. Supreme Court jurisprudence defining when an unwed/biological father has protected rights

  • Lehr v. Robertson — The majority treats Lehr as the doctrinal key: biology alone is insufficient, but biology plus a demonstrated “full commitment to the responsibilities of parenthood” yields “substantial protection under the Due Process Clause.” The Court applies that test to Hardy’s conduct (cohabitation with the child, daily caretaking, financial support, formal acknowledgment, and persistent efforts to maintain contact).
  • Lassiter v. Department of Social Services — Cited for the weight of the parent-child liberty interest (more important than property rights) and for due-process sensitivity when the state’s action implicates parental bonds.
  • Stanley v. Illinois, Quilloin v. Walcott, Caban v. Mohammed — Listed as foundational cases in the evolution of constitutional recognition of unwed fathers’ interests, supporting the majority’s general proposition that the Constitution sometimes protects paternal interests when accompanied by responsibility and relationship.
  • Michael H. v. Gerald D. — Used by both sides, but for different ends:
    • The majority distinguishes Michael H. factually: in Michael H., the child was born into an existing marital family unit with a husband who desired to raise the child. Here, the child was conceived and born into the biological father’s household, and the presumed father had no relationship with the child.
    • The dissents invoke Michael H. (and Kinnett’s reading of it) to stress that states may constitutionally privilege marital/presumptive parenthood as legislative policy.

3. Louisiana precedent on Article 198 and legislative policy choices

  • Kinnett v. Kinnett — The controlling baseline. Kinnett upheld Article 198 as applied where the child was born into a family unit involving the mother and the presumed father, and where the putative father was not similarly situated as a functioning parent within that unit. Davidson v. Hardy treats Kinnett not as overruled, but as limited: Kinnett governs “intact family unit” scenarios; this case governs a “biological-father family unit” scenario.

4. Authorities emphasized in the dissents (legislative primacy, standards of review, limitations periods)

  • Welch v. United Med. Healthwest-New Orleans L.L.C. — Cited by Chief Justice Weimer for the proposition that where a claimant asserts a right other than a fundamental right, restrictions need only satisfy rational-basis review.
  • Dobbs v. Jackson Women's Health Org. — Cited in dissent for the methodology for identifying “fundamental” rights as those deeply rooted in history and tradition; used to argue a biological father’s claim against a legal presumption is not such a right.
  • Gallo v. Gallo — Cited to reinforce the strength and historical protection of the marital presumption.
  • Carver v. Louisiana Dep't of Pub. Safety, M.J. Farms, Ltd. v. Exxon Mobil Corp., State in Interest of D.D. — Cited by Justice Penzato for the strong presumption of constitutionality and the challenger’s heavy burden.
  • W.R.M. v. H.C.V., T.D. v. M.M.M., Fishbein v. State ex rel. Louisiana State Univ. Health Scis. Ctr., Miller v. Thibeaux — Cited to describe the pre-Article-198 era of inconsistent judge-made timeliness standards and to argue Article 198 was enacted to restore clarity through a bright-line peremptive period.
  • Reeder v. North, Ring v. State, Department of Transportation and Development, Cooper v. Lykes, Atchafalaya Land Co. v. F.B. Williams Cypress Co., Kentucky Union Co. v. Commonwealth of Kentucky, Falgout v. Dealers Truck Equip. Co., Lott v. Haley — Cited by Justice Penzato for the proposition that limitation periods are legislative prerogatives and are typically constitutional if they provide a reasonable opportunity to sue.
  • Giroir v. S. Louisiana Medical Center, Div. of Hosps., Denham Springs Econ. Dev. Dist. v. All Taxpayers, Prop. Owners & Citizens of Denham Springs Econ. Dev. Dist., Willis-Knighton Med. Ctr. v. Caddo Shreveport Sales & Use Tax Comm'n — Cited for policy reasons supporting firm enforcement of prescriptive/peremptive rules even when harsh.

B. Legal Reasoning

1. The majority’s doctrinal move: from statutory “avowal deadline” to constitutional liberty interest

The majority frames the decisive question as due process protection of an established parent-child relationship, not as a simple application of a legislative deadline. Relying heavily on Lehr v. Robertson and In re Adoption of B.G.S., the Court reasons that Hardy’s biology plus his concrete parental conduct created a vested liberty interest.

2. The “family unit” distinction becomes outcome-determinative

The Court imports from Kinnett v. Kinnett a “clear distinction” between:

  • protecting the rights of parents in the family unit into which the child is born, and
  • a putative biological father not living in a family unit with the child.

It then flips the factual premise: here, Z.H. was born into Hardy’s household, Hardy acted as father from birth, and the presumed father had no relationship. On those facts, the state’s justification (protecting the child from upheaval by stabilizing an intact presumed-father family) is deemed inapplicable or perverse: enforcing Article 198 would itself create upheaval by severing the child’s only father relationship.

3. How “as applied” does the work

The Court does not invalidate Article 198 on its face. It holds only that the one-year peremptive bar is unconstitutional as applied under the factual circumstances presented. That matters because it:

  • leaves Article 198 in force for many cases (including “intact family unit” scenarios like Kinnett), but
  • creates a constitutional backstop when rigid application would destroy a protected liberty interest without adequate justification.

4. The dissent’s counter-framing: forfeiture of a legislatively granted remedy, not state deprivation of a constitutional right

Both dissents emphasize that Article 198 grants a right to sue even when a legal father exists, but conditions it on timeliness; the father’s problem is not state deprivation, but missed deadline. They argue (a) biology is not a fundamental right; (b) the legislature may rationally select a bright-line deadline to reduce litigation-driven instability; and (c) case-by-case constitutional exceptions revive the pre-2004 uncertainty that Article 198 was enacted to end.

C. Impact

1. A new constitutional “safety valve” for Article 198 peremption

This decision establishes that Article 198’s one-year peremptive period cannot always be applied mechanically when it would extinguish a biological father’s already-formed, constitutionally protected parent-child relationship—particularly where the presumed father is purely “legal on paper” and the child was born and raised (at least initially) in the biological father’s home.

2. Likely litigation focus: factual development of “commitment,” “family unit,” and “attachment”

Future cases will likely litigate the fact-intensive questions the majority treated as decisive:

  • Was the child born into the biological father’s household or a household including the presumed father?
  • Did the biological father promptly acknowledge paternity and undertake daily caretaking and support?
  • What is the child’s relationship/attachment to the presumed father (if any)?
  • Would applying Article 198 reduce or increase “upheaval” for the child?

As a practical matter, this invites more as-applied constitutional challenges to Article 198, with hearings resembling best-interest/attachment inquiries even though the formal issue is timeliness and constitutional due process.

3. Tension with legislative bright-line predictability

The dissents highlight a structural consequence: a bright-line peremptive rule provides predictability; an as-applied due process exception introduces uncertainty. Trial courts may now need to decide whether the state’s asserted interests behind Article 198 (stability, avoidance of upheaval) fit the real family lived by the child, not the legal presumption alone.

IV. Complex Concepts Simplified

  • Presumed father (La. C.C. art. 185): If a child is born during a marriage or within 300 days after it ends, the husband is presumed the father, even if he is not the biological father.
  • Avowal / action to establish paternity (La. C.C. art. 198): The biological father’s lawsuit to be legally recognized as the child’s father.
  • Peremption: A hard deadline that extinguishes the right itself (not just the remedy) and generally cannot be interrupted or suspended.
  • “As applied” unconstitutionality: The statute remains valid in general, but cannot constitutionally be used in the specific circumstances of the case.
  • Liberty interest / due process: The Constitution can protect certain family relationships; if the state (including through its courts) applies a law in a way that unjustifiably destroys such a protected relationship, due process may be violated.
  • “Grasping the opportunity” (from Lehr): A biological father gains constitutional protection when he promptly steps forward and actually undertakes parental responsibilities—showing commitment, not mere genetics.

V. Conclusion

Davidson v. Hardy reshapes Louisiana’s Article 198 landscape by holding that the one-year peremptive bar is unconstitutional as applied when it would sever a biological father’s established, responsibility-based parent-child relationship in a setting where the child was born into the biological father’s family unit and has no meaningful relationship with the presumed father. The decision narrows Kinnett v. Kinnett to its “intact presumed-family unit” context and signals that, in exceptional factual settings, due process can override rigid peremptive timelines designed for different family realities.
