01 · Why this page exists
A skill that states Missouri law without a citation teaches the model to state Missouri law without a citation — the exact habit this site warns against. It also cannot be maintained: when a breath-testing rule or a statute is amended, nothing in a citation-free skill flags that anything needs updating. So every proposition is pinned to a primary source and a date, or it is marked ⛔ OPEN and withheld.
02 · The rules
- Statutory text comes from the Missouri Revisor (revisor.mo.gov); regulations from the Secretary of State 19 CSR rules PDF — always the version that is operative on the answer date. The Revisor even displays a future § 577.010 effective August 28, 2026; that text is not law yet and is not merged into a current-law answer.
- Every case is verified through CourtListener for existence and reporter citation before it enters a skill.
- Check appellate history before citing. A missing reporter cite on a Court of Appeals opinion can mean transfer, not a database gap. Worked example: the Ross disposition at WD69900 was superseded on transfer — the citable authority is Ross v. Director of Revenue, 311 S.W.3d 732 (Mo. banc 2010). Citing WD69900 as final means citing a superseded opinion.
- Pin cite to the subsection, never the bare section. § 577.041.3, not § 577.041. § 302.530, not "the hearing statute." § 577.010.6, not "the DWI penalty statute." The subsection is where the errors live.
- Date-stamp the authority file. The breath-testing rules carry amendment dates — 19 CSR 25-30.031/.041/.050/.051/.060 effective March 30, 2020; .021 effective June 30, 2023 — and statutes carry effective dates and pending amendments. mo-dwi-authority.md records each.
- A repealed section is not authority. § 577.026 was repealed effective January 1, 2017; the current PBT exemption is §§ 577.019 and 577.020. Citing a repealed section is a silent error that only a text pull catches.
- Where a proposition cannot be verified, it is marked ⛔ OPEN and does not ship. mo-dwi-authority.md names each open item. The promise is that the skills refuse to invent facts; that promise binds the authority file first.
- The attorney signs. Not the model.
03 · Real corrections this verification pass caught
Pulling the primary text — not reading the draft — surfaced each of these:
- The administrative 15-day hearing deadline is § 302.530, not § 302.525. A draft had the wrong section; the Revisor listing settles it ("within fifteen days of receipt of the notice").
- § 577.023 is procedure only — pleading, proof, and findings of repeat-offender status. The definitions are § 577.001; the classifications are §§ 577.010/.012; the ranges are §§ 558.011/.002. Attributing the offender ladder or a penalty range to § 577.023 is wrong.
- § 577.021 exempts a pre-arrest PBT from §§ 577.019 and 577.020, not from the repealed § 577.026. The old proposition survives in pre-2017 cases only.
- IID eligibility and duration live in Chapter 302 (§§ 302.440/.525/.060), not §§ 577.600–.614 (which create related offenses). A Limited Driving Privilege (§ 302.309) is not the same as a Restricted Driving Privilege (§ 302.010(20), § 302.525).
04 · What is watched or still open
mo-dwi-authority.md marks every unverified or contingent item, currently including: the August 28, 2026 amendments to § 577.010 and § 302.440 (held separate until effective); and the fact that no fixed SATOP hour count exists in statute — it is assessment-driven, so none is asserted. Cases carrying only a docket number are confirmed to a reporter citation through CourtListener before they are relied on.
