Yes. South Dakota Class 1 misdemeanors carry up to 1 year and $2,000 fine; Class 2 up to 30 days and $500 fine. Suspended Imposition (§ 23A-27-13) — completion means no conviction on record — is invaluable for first-offenders. DV and DUI convictions trigger major collateral consequences including federal firearm prohibitions.

State cases go through South Dakota Circuit Court. Federal cases go to U.S. District Court for the District of South Dakota (Northern Division — Aberdeen, Central — Pierre, Southern — Sioux Falls, Western — Rapid City) under the U.S. Sentencing Guidelines. Federal cases commonly involve drug trafficking, § 922(g) firearm cases, Major Crimes Act / Indian Country jurisdiction (significant in South Dakota with 9 federally recognized tribes), wire fraud, and federal program fraud.

South Dakota plea agreements under SDCL § 23A-7-8 are negotiated between the State’s Attorney and defense. Pleas can include charge reductions, Suspended Imposition (§ 23A-27-13 — successful completion = no conviction), suspended execution of sentence, drug court entry, DUI court, mental health court, and stipulated sentence recommendations.

Most misdemeanors expungeable after 5 years; certain non-violent felonies after 10 years; violent and sex offenses generally not expungeable. Suspended Imposition completion (§ 23A-27-13) means no conviction on record.

Why Do You Need a Criminal Defense Attorney in South Dakota?

South Dakota classifies crimes under SDCL Title 22. Felonies are Class A (life, possible death), B (life), C (life), 1 (50 years), 2 (25 years), 3 (15 years), 4 (10 years), 5 (5 years), and 6 (2 years) (§ 22-6-1). Misdemeanors are Class 1 (1 year max) and Class 2 (30 days max). Murder carries Class A or B (mandatory life or death for Class A) — South Dakota retains the death penalty but has not executed since 2019. South Dakota legalized medical marijuana via Initiated Measure 26 (2020), codified at SDCL § 34-20G. Recreational marijuana was approved by Amendment A (2020) but struck down by the South Dakota Supreme Court (Thom v. Barnett, 2021). Recreational marijuana remains illegal — possession (under 2 oz) is a Class 2 misdemeanor (§ 22-42-6). Suspended Imposition of Sentence (SDCL § 23A-27-13) is the primary first-offender diversion — successful completion means no conviction on record. Expungement under § 23A-3-27 (non-conviction) is broad; conviction expungement under § 23A-3-34 is narrower. South Dakota State’s Attorneys are elected county prosecutors with substantial discretion.
