Sentencing Guidelines Commission training: which manual to use after Robinette and other timing rules

Unidentified Presenter, a trainer with the Sentencing Guidelines Commission, told attendees on Oct. 23, 2025, that the "current" sentencing guidelines are those in effect when the current offense occurred and that ameliorative changes decided in Robinette apply regardless of the original offense date.

The presenter said the guidance means: for most purposes after 2019, practitioners should use the manual in effect at the time of the current offense. "The guidelines in effect when the current offense occurred," the presenter said, "is the manual that is current with respect to the guidelines." The trainer added that because the commission and courts did not retroactively reissue older manuals, one may still need to consult archived manuals to locate historical policy text even while using the later manual for criminal-history calculations.

Why this matters: a practitioner's choice of manual affects severity-level assignments, modifiers, mandatory minimums and the grid used to determine a presumptive sentence. The presenter pointed attendees to the Sentencing Guidelines Commission website (mn.gov/sentencing-guidelines) and demonstrated how to access archived manuals and year-by-year grids dating back to 1980.

The session also noted a temporary effective-date difference that occurred in 2021 (a Sept. 15–July 31 cycle) and cautioned attendees to verify the correct effective cycle when pulling an archival manual. The trainer emphasized that ameliorative statutes and policies that reduce punishment should be applied even if they postdate the charged offense, per the Supreme Court ruling discussed in the webinar.

The presenter closed by offering the commission as a resource if attendees had questions about which manual applies in particular cases.
