Primary HB 1238
Signed into law · South Dakota House · Lead sponsor
protect financial institutions taking action to prevent the financial exploitation of consenting, senior, or vulnerable adults.

Maddy summaryHB 1238 allows South Dakota financial institutions to delay or block specific transactions when they reasonably suspect financial exploitation of consenting adults aged 65+ (seniors) or adults aged 18+ with mental impairments or court-appointed guardians (vulnerable adults). The law permits banks to refuse transfers, withdrawals, ownership changes, beneficiary updates, or power-of-attorney instructions if exploitation is suspected. Financial institutions are protected from liability for acting under this law, though they are not required to intervene - decisions are based on available information. This directly affects banks and the vulnerable adults they serve by providing a legal framework to prevent financial abuse.

Primary HB 1099
Signed into law · South Dakota House · Lead sponsor
reschedule the pharmaceutical composition of crystalline polymorph psilocybin in a drug product approved by the Food and Drug Administration as a Schedule IV controlled substance.

Maddy summaryHB 1099 would reclassify FDA-approved psilocybin medications from Schedule I to Schedule IV under South Dakota law. This change would allow medical providers to prescribe these specific pharmaceutical products without the strict restrictions currently applied to Schedule I substances. The bill specifically affects only psilocybin in drug products approved by the FDA, not raw psilocybin or unapproved formulations. This amendment aligns South Dakota's scheduling with federal approval status for medical use.

Primary HB 1101
Signed into law · South Dakota House · Lead sponsor
prohibit an insurer from declining or limiting life, disability, or long-term care insurance policies based solely on an individual's status as a living organ donor.

Maddy summaryHB 1101 prohibits insurers from denying or limiting life, disability, or long-term care insurance coverage solely because someone is a living organ donor. It specifically bans insurers from: (1) refusing coverage based on donor status, (2) requiring donors to stop donating to maintain coverage, or (3) charging higher premiums or imposing other restrictions due to donor status alone. The bill ensures that living organ donors cannot face insurance discrimination without evidence of actual increased health risk. This directly protects individuals who donate organs while alive from unfair treatment by insurance companies.

Primary HB 1143
Signed into law · South Dakota House · Lead sponsor
authorize the possession and self-administration of diabetes medications by a student on school property and at school-related events and activities.

Maddy summaryHB 1143 allows students with diabetes to possess and self-administer nasal glucagon (a medication for severe low blood sugar) on school property or at school events. It directly affects students diagnosed with diabetes who require this specific treatment. The bill requires a licensed healthcare provider’s diagnosis, written parent authorization, and a physician’s statement detailing the medication’s purpose, dosage, and administration guidelines to be kept on file at the school. Schools must maintain these documents in the student’s health record or with the school nurse. This change expands existing provisions for asthma and anaphylaxis medications to include nasal glucagon for diabetes management.

Primary SB 87
Signed into law · South Dakota Senate · Lead sponsor
clarify and establish requirements related to forensic medical examinations.

Maddy summarySouth Dakota's SB 87 ensures counties cover the full cost of forensic medical examinations for victims of sexual assault or rape, eliminating out-of-pocket expenses for victims. The bill specifies covered costs include physician services, necessary tests (like STD screenings and pregnancy tests), supplies, and medications, with payments capped at Medicaid rates. It allows minors aged 16+ to consent to exams without parental permission and permits exams for protected persons without guardian consent, provided informed consent is obtained. Hospitals and clinics cannot bill victims beyond these Medicaid-based limits, and must notify victims of their no-cost access regardless of cooperation with law enforcement.

Introduced · South Dakota Senate · Lead sponsor
celebrating Solventum's expansion of its Brookings, South Dakota, manufacturing facility.

Primary SB 93
Passed · South Dakota Senate · Lead sponsor
prohibit certain state officers or employees from being employed by an organization that was the recipient of a contract awarded on behalf of a state agency for a period of time.

Maddy summarySB 93 prohibits state employees who approve, award, or administer state contracts from working for the organizations that received those contracts after leaving state service. For contracts under $1 million, this creates a one-year waiting period; for contracts over $1 million, it extends to two years. The bill allows exceptions if a governing body authorizes the arrangement through written disclosure and approval, ensuring the arrangement is fair and in the public interest. This applies to employees handling contracts within their official duties, excluding unpaid or per diem roles.

Primary SB 116
Signed into law · South Dakota Senate · Lead sponsor
make an appropriation for the design and construction of an indoor athletics facility at Dakota State University and to declare an emergency.

Maddy summarySB 116 appropriates $13.33 million for the design and construction of an indoor athletic facility at Dakota State University's Beacom PREMIER Complex in Madison. It directly affects Dakota State University's athletic programs and campus infrastructure. The bill authorizes the Board of Regents to use the funds for the project, including related services like utilities and landscaping, and allows adjustments for inflation (capped at 125% of the original estimate). It also permits accepting additional funds from federal sources or donations into a dedicated project fund, while declaring an emergency to expedite the funding. The facility will support athletic practice and competition, with no state liability for related expenses.

Primary HB 1073
died · South Dakota House · Lead sponsor
provide for the creation of a cardiac emergency plan in every school and to make an appropriation therefor.

Maddy summaryHB 1073 requires every public and accredited nonpublic school in South Dakota to create a cardiac emergency response plan. The bill mandates schools to develop these plans with local emergency services, including forming response teams, placing accessible automated external defibrillators (AEDs) in schools and athletic venues, and training staff in CPR and AED use. Schools must conduct annual drills and maintain AEDs, with specific training requirements for coaches, athletic trainers, nurses, and response team members. This law directly affects all South Dakota schools and aims to improve emergency response for heart-related incidents during school activities.

Primary HB 1105
Passed · South Dakota House · Lead sponsor
restrict contracts and declarations that prohibit the use of commercial or residential property for any healthcare service in medically underserved areas or communities, or in areas with a medically underserved population under federal law.

Maddy summaryHB 1105 prevents property owners in specific areas from using contracts or declarations to block healthcare services on commercial property. It applies to municipalities/townships under 3,000 people (per federal census) or areas officially designated as medically underserved by South Dakota’s Department of Health. The bill invalidates any contract or declaration that restricts the use of commercial property for healthcare services like clinics, diagnoses, or treatment in these areas. This directly affects property owners and developers who previously could impose such restrictions, while enabling healthcare providers to operate in underserved communities.
