904 N.W.2d 162
Iowa2017Background
- Donald Hitzhusen (decedent) left most of his estate to his former stepchildren Paula Tyler and Mark Alcorn and to their mother Constance; Paula and Mark paid inheritance tax under protest and sought a refund.
- Iowa statute (Iowa Code § 450.1(l)(e), adopted in 2003) defines “stepchild” for the inheritance-tax exemption to mean a child of a person who was married to the decedent at the time of the decedent’s death (or whose spouse died during the marriage), excluding children of former spouses if the marriage ended by divorce before the decedent’s death.
- The Iowa Department of Revenue denied the refund because Constance and Donald were divorced at Donald’s death, so Paula and Mark did not qualify as stepchildren under the statutory definition.
- Paula and Mark challenged the statute under article I, section 6 of the Iowa Constitution (uniform operation/equal protection). The administrative law judge and the district court upheld the statute; the Iowa Supreme Court retained the appeal.
- The court applied rational-basis review for taxation statutes and evaluated whether the statutory classification (excluding post-divorce former stepchildren) is rationally related to legitimate state interests in promoting family stability and administrative efficiency.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Iowa Code § 450.1(l)(e)’s exclusion of stepchildren after divorce violates article I, § 6 (equal protection) | Paula & Mark: They remain similarly situated to stepchildren whose parent and stepparent were married at death; exclusion is arbitrary and discriminates against them | State/Dept: Legislature may rationally treat stepchildren differently after divorce because divorce dissolves the family unit; exemption promotes intact family relationships and administrative economy | Held: Upheld. Classification satisfies rational-basis review as reasonably related to legitimate state interests (promoting family stability, administrative practicality) |
