Sentencing Courts May Consider Uncharged Conduct Without Explicit “Preponderance” Findings When the Record Supports It and the Defendant Can Contest It

1. Introduction

In State v. Martin, 2025 S.D. 15, the South Dakota Supreme Court addressed the limits of a sentencing court’s discretion when it considers uncharged conduct described in a presentence investigation report (PSI). The defendant, Chad Dale Martin, pleaded guilty to vehicular battery (SDCL 22-18-36) and aggravated eluding (SDCL 32-33-18.2), and admitted a part II habitual offender information under SDCL 22-7-8.

The case arose from a high-speed chase in Sioux Falls that ended in a collision injuring an occupant of another vehicle. Although Martin was not charged for an earlier incident involving the alleged theft of the vehicle and injuries to two people during that theft, the PSI included police reports describing that episode. At sentencing, the circuit court referenced those uncharged events and imposed a sentence exceeding the State’s penitentiary cap recommendation (though still within statutory limits as enhanced by the habitual offender admission).

On appeal, Martin argued the circuit court abused its discretion by considering uncharged conduct at sentencing—especially without making an express finding that the conduct was proven by a preponderance of the evidence.

2. Summary of the Opinion

The Supreme Court of South Dakota affirmed. It held that a sentencing court does not commit reversible error merely because it considers uncharged conduct described in the PSI without making explicit findings that the State proved the conduct by a preponderance of the evidence—so long as:

  • the defendant had an opportunity to contest the information,
  • the record contains sufficient evidence to support a preponderance determination, and
  • the sentence imposed is within the statutory maximum and otherwise within the range of permissible choices.

The Court emphasized that South Dakota sentencing practice does not generally require “detailed findings of fact to justify a sentence,” and it applied a presumption that, absent contrary indications, the court used the proper standard of proof.

3. Analysis

A. Precedents Cited

The Opinion draws on a consistent line of South Dakota authority recognizing broad sentencing discretion, permissive evidentiary rules at sentencing, and limited appellate interference when the sentence is within lawful bounds.

1) Sentencing discretion and review standards

  • State v. Peltier, 2023 S.D. 62, ¶ 29, 998 N.W.2d 333, 342: reiterates abuse-of-discretion review for sentencing decisions.
  • State v. Lanpher, 2024 S.D. 26, ¶ 25, 7 N.W.3d 308, 317: defines abuse of discretion as a choice outside the range of permissible choices.
  • State v. Mitchell, 2021 S.D. 46, ¶ 27, 963 N.W.2d 326, 332 (quoting State v. Klinetobe, 2021 S.D. 24, ¶ 26, 958 N.W.2d 734, 740): requires a demonstrated and prejudicial error to warrant reversal.

These cases set the appellate lens: Martin’s argument had to show not only an error, but an unreasonable sentencing choice that caused prejudice.

2) What information a court may consider at sentencing

  • State v. Rice, 2016 S.D. 18, ¶ 23, 877 N.W.2d 75, 83 (quoted in Mitchell): confirms broad discretion within constitutional and statutory limits.
  • State v. Black Cloud, 2023 S.D. 53, ¶ 66, 996 N.W.2d 670, 686: identifies traditional sentencing aims—retribution, deterrence, rehabilitation, incapacitation— without preeminence among them.
  • State v. Banks, 2023 S.D. 39, ¶¶ 18–19, 994 N.W.2d 230, 235: emphasizes assessing the “true nature of the offense” and notes that the rules of evidence do not apply at sentencing hearings.
  • State v. Arabie, 2003 S.D. 57, ¶ 21, 663 N.W.2d 250, 257: recognizes “wide discretion” as to type/source of sentencing information.
  • State v. Caffee, 2023 S.D. 51, ¶ 28, 996 N.W.2d 351, 360: clarifies that sentencing is not confined to a stipulated plea factual basis.

Together, these precedents underpin the Court’s core move: a sentencing judge may consider broad, reliable information—including police reports in a PSI—when deciding how to sentence within the legislature’s authorized range.

3) Uncharged conduct and due process protections

  • State v. McKinney, 2005 S.D. 74, ¶ 18, 699 N.W.2d 460, 466: a defendant must have the opportunity to contest uncharged conduct.
  • State v. Mitchell, 2021 S.D. 46, ¶ 31, 963 N.W.2d 326, 333: courts may consider uncharged conduct if the State proves it by a preponderance of the evidence.
  • Wabasha v. Leapley, 492 N.W.2d 610, 612 (S.D. 1992): due process requires an opportunity to rebut or explain contested factual information relied upon at sentencing.

These cases supply the constitutional “guardrails”: the State must meet a preponderance burden and the defendant must be able to challenge the claim—yet the procedural formality of how that burden is memorialized (explicit findings versus record support) is the disputed question Martin presented.

4) No general requirement of detailed sentencing findings (and the presumption of correct standards)

  • State v. Bear Robe, 2024 S.D. 77, ¶ 16, 15 N.W.3d 460, 466: the Court has never required detailed findings of fact to justify a sentence.
  • Hoffman v. Hollow Horn, 2024 S.D. 59, ¶ 15 n.6, 12 N.W.3d 322, 327 n.6: where a court does not explicitly state the standard of proof, a rebuttable presumption applies that the proper standard was used.

These authorities are pivotal: they allow the Court to reject Martin’s demand for explicit, on-the-record preponderance findings as a categorical rule.

5) Rejecting “mini-trials” at sentencing; assessing credibility

  • State v. Carsten, 264 N.W.2d 707, 709-10 (S.D. 1978): sentencing courts are not required to accept implausible accounts or conduct mini-trials.
  • State v. Miles, 2021 S.D. 13, ¶¶ 20-21, 956 N.W.2d 61, 67-68; State v. Murphy, 506 N.W.2d 130, 133 (S.D. 1993); State v. Garber, 2004 S.D. 2, ¶ 33, 674 N.W.2d 320, 328: support considering a defendant’s truthfulness/remorse and rejecting incredulous explanations in the PSI.

The Court used these cases to validate the sentencing judge’s choice to credit the PSI’s official version over Martin’s shifting explanations for his possession of the car.

6) Circumstantial proof of identity and inferences from possession of stolen property

  • State v. Podzimek, 2019 S.D. 43, ¶¶ 32-33, 932 N.W.2d 141, 149: identity can be proven by circumstantial evidence.
  • State v. Deubler, 343 N.W.2d 380, 382 (S.D. 1984): circumstantial evidence supported grand theft where the defendant was apprehended in the stolen vehicle and gave conflicting stories.
  • State v. Dowty, 2013 S.D. 72, ¶ 19 n.9, 838 N.W.2d 820, 827 n.9 (quoting State v. Larkin, 87 S.D. 61, 67, 202 N.W.2d 862, 865 (1972)): possession of recently stolen property is a circumstance from which guilt may be presumed.

These cases provided the evidentiary logic for the Court’s conclusion that the record supported a preponderance determination that Martin committed the earlier theft-related conduct, even without direct identification evidence.

7) Distinguishing demands for explicit findings in other contexts

  • State v. Feucht, 2024 S.D. 16, ¶ 30, 5 N.W.3d 561, 570: required explicit listing of aggravating factors to depart from presumptive probation under SDCL 22-6-11.
  • State v. Deleon, 2022 S.D. 21, ¶ 24, 973 N.W.2d 241, 247 (quoting State v. Bult, 1996 S.D. 20, ¶ 12, 544 N.W.2d 214, 217): reiterates no general requirement for detailed findings absent a legislative mandate.

The Court treated Feucht as statutory-exceptional: SDCL 22-6-11 created a specific findings obligation in a narrow setting. Because Martin received a fully suspended sentence on the Class 6 aggravated eluding conviction, the SDCL 22-6-11 departure mechanism was not triggered in a way that required explicit aggravator findings.

8) Out-of-state authority and why it did not control

  • United States v. Schaefer, 291 F.3d 932, 938-39 (7th Cir. 2002): invoked by Martin for explicit findings under a preponderance standard.

The Court explained that United States v. Schaefer involved then-mandatory federal sentencing guidelines and enhancement factfinding tied to guideline calculations. By contrast, Martin’s case involved an indeterminate state sentence within a statutory maximum and the traditional discretion of the sentencing court; the Court found the federal-guidelines context materially distinct.

9) “Within the statutory maximum” and permissible range

  • State v. Henry, 2024 S.D. 30, ¶ 28, 7 N.W.3d 907, 913-14: affirms that a sentence within the statutory maximum and within permissible choices is generally upheld.

B. Legal Reasoning

The Court’s reasoning proceeds in three steps that together create the operative rule:

  1. Sentencing may consider broad information, including uncharged conduct, under relaxed evidentiary rules. The Court reaffirmed that sentencing aims to assess the “true nature of the offense” and the defendant’s background, and that courts may consult PSIs and police reports even if such material might not be admissible at trial (Banks; Arabie; Caffee).
  2. Due process is satisfied if the defendant can contest, and the record supports a preponderance finding. The Court reiterated the governing standard (uncharged conduct must be proven by a preponderance; defendant must have an opportunity to contest) (McKinney; Mitchell; Wabasha v. Leapley), and then focused on the practical question: whether the circuit court’s reliance was supported and contestable. Martin had the PSI, did not object to it, and his counsel explicitly disputed the theft narrative at sentencing—demonstrating the opportunity to contest.
  3. Explicit preponderance findings are not categorically required. Relying on State v. Bear Robe (no detailed findings requirement) and Hoffman v. Hollow Horn (presumption that the correct standard was used), the Court held that the absence of an explicit “preponderance” finding does not itself establish error. Appellate review instead asks whether the record contains sufficient evidence that would support such a finding and whether the process allowed contesting.

Applying these principles to the facts, the Court held that circumstantial evidence supported attributing the earlier theft-related conduct to Martin: he was found driving the recently stolen vehicle, he engaged in reckless flight, and he gave conflicting accounts of how he obtained the car (with the PSI containing a version that he watched the car running and then took it). The Court cited theft/identity circumstantial-evidence cases (State v. Podzimek; State v. Deubler; State v. Dowty (quoting State v. Larkin)) to support the inference.

Finally, the Court underscored that the sentence was not based solely on the uncharged conduct: it also rested on Martin’s extensive criminal history, parole violations, substance use, and the danger posed by the high-speed chase causing serious injury—placing the sentence within the “range of permissible choices” (State v. Henry).

C. Impact

State v. Martin clarifies (and effectively lowers the procedural temperature around) a recurring sentencing dispute: whether trial courts must make explicit on-the-record findings when considering uncharged conduct. The decision’s practical effects include:

  • Appellate framing: challenges based solely on the absence of explicit “preponderance” findings will be difficult to win unless the defendant can show the record lacked sufficient support or the defendant lacked a meaningful opportunity to contest.
  • Greater emphasis on the PSI process: defendants who want to limit sentencing exposure from uncharged allegations must timely object, request corrections, offer rebuttal evidence, and create a record—because silence or undeveloped objections increases the likelihood that PSI facts will be treated as reliable.
  • Reinforcement of discretion over formalism: the Opinion preserves indeterminate-sentencing flexibility and resists importing federal-guidelines-style factfinding requirements (distinguishing United States v. Schaefer).
  • Boundary with statutory mandates: the Court distinguishes situations where the Legislature has required explicit findings (as in State v. Feucht under SDCL 22-6-11), signaling that explicit findings are the exception, not the rule, absent a specific statutory directive.

4. Complex Concepts Simplified

Uncharged conduct
Alleged behavior not included in the formal criminal charges of conviction. At sentencing, courts may still consider it as part of understanding the defendant and the offense, if due process safeguards are met.
Preponderance of the evidence
The “more likely than not” standard. It is lower than “beyond a reasonable doubt,” which applies at trial for guilt on charged offenses.
Presentence Investigation (PSI)
A report prepared for sentencing that often includes criminal history, personal background, risk factors, and police reports. Courts frequently treat it as a generally reliable compilation—unless disputed and shown inaccurate.
Opportunity to contest
Due process at sentencing typically requires that the defendant has access to the information the judge will rely on and a chance to rebut, explain, or correct it—through objections, argument, and sometimes evidence.
Abuse of discretion
A highly deferential appellate standard. The question is not whether the appellate court would have imposed a different sentence, but whether the sentencing choice was arbitrary, unreasonable, or outside lawful options.
Indeterminate sentencing
A sentencing structure granting the judge discretion within statutory maximums (as opposed to rigid guideline calculations). This context matters to why the Court did not require the kind of precise findings associated with guideline enhancements.

5. Conclusion

State v. Martin reinforces a pragmatic rule in South Dakota sentencing law: a court may consider uncharged conduct described in a PSI without issuing explicit “preponderance” findings, as long as the defendant can contest the allegations and the record contains enough evidence to support the court’s reliance under the preponderance standard. The decision preserves broad sentencing discretion, emphasizes the importance of the PSI and the defendant’s obligation to timely challenge disputed facts, and distinguishes statutory contexts (like SDCL 22-6-11 in State v. Feucht) where explicit findings are legislatively required.
