Passive Noncompliance as “Physical Interference” Under § 575.150: Refusal to Unlock a Vehicle Door During Another’s Arrest

1. Introduction

State of Missouri v. Brian V. Milazzo (Supreme Court of Missouri, en banc) addresses the meaning of “using … physical interference” in Missouri’s “interfering with an arrest” statute, § 575.150.1. During a driver’s license checkpoint, officers attempted to arrest a passenger in Milazzo’s truck after the passenger refused to identify himself for a seatbelt citation and refused to exit the vehicle. The key factual dispute was whether Milazzo—by refusing to unlock the passenger-side door despite repeated commands—committed the class A misdemeanor of interfering with the passenger’s arrest.

The central legal issue was narrow but consequential: whether “physical interference” under § 575.150 requires an affirmative, active act (as Milazzo argued) or can be satisfied by passive noncompliance that maintains a physical barrier impeding officers from completing an arrest (as the State contended).

2. Summary of the Opinion

The Court affirmed Milazzo’s conviction, holding the evidence was sufficient for a reasonable jury to find Milazzo “used physical interference” by refusing to unlock the passenger-side door during the passenger’s arrest. Although Milazzo characterized his conduct as a “passive omission,” the Court concluded § 575.150’s plain language does not require an affirmative act. A defendant violates the statute when he “allows a material thing” (here, the locked door as a physical barrier) to be the means of hampering an arrest, in circumstances where the defendant’s purpose is to prevent the officer from effectuating the arrest.

3. Analysis

A. Precedents Cited

• State v. Chaney, 967 S.W.2d 47 (Mo. banc 1998): The Court relied on Chaney for the principle that appellate review of sufficiency is highly deferential—courts do not act as a “super juror.” This framing mattered because Milazzo’s argument invited the Court to reassess what the jury could infer from the videos and testimony.
• State v. Gilmore, 537 S.W.3d 342 (Mo. banc 2018): Gilmore supplied the controlling methodology for sufficiency review: accept as true evidence supporting guilt and reasonable inferences supporting the verdict; ignore contrary evidence and inferences; do not supply missing evidence or indulge speculative inferences. The Court explicitly used this lens to disregard Milazzo’s contrary testimony (e.g., that he was not told to unlock the door) because the officers testified to repeated commands.
• Middleton v. Mo. Dep't of Corr., 278 S.W.3d 193 (Mo. banc 2009): Middleton supported de novo review of statutory interpretation. That mattered because the case turned on the legal meaning of “using … physical interference,” not merely on factual reconstruction.
• Matthews v. Harley-Davidson, 685 S.W.3d 360 (Mo. banc 2024): Matthews was cited for the interpretive rule that undefined statutory terms are given their plain and ordinary meaning, often derived from dictionaries. This enabled the Court’s dictionary-based construction of “use,” “physical,” and “interference.”
• State v. Yount, 642 S.W.3d 298 (Mo. banc 2022): Yount reinforced the principle that each word and clause in a statute should be given meaning. This supported reading “use” as a distinct requirement—focusing on the “means” by which interference is accomplished—rather than collapsing the phrase into a narrower “affirmative act” requirement not expressed in the text.
• Kehlenbrink v. Dir. of Revenue, 577 S.W.3d 798 (Mo. banc 2019): Kehlenbrink provided the caution that statutory terms must be read in context, not in isolation. Here, the Court read “use” and “physical interference” together, in the setting of preventing officers from effectuating an arrest.
• United Pharmacal Co. of Mo. v. Mo. Bd. of Pharmacy, 208 S.W.3d 907 (Mo. banc 2006): United Pharmacal was invoked to avoid hypertechnical parsing and to favor a reasonable, logical interpretation that gives meaning to the statute. This supported rejecting Milazzo’s attempt to graft an “affirmative act” limitation onto the text.

B. Legal Reasoning

The Court’s reasoning proceeded in three main steps:

1. Define the statutory phrase by ordinary meaning. Because § 575.150 does not define “using … physical interference,” the Court consulted dictionary meanings: “use” as “to carry out a purpose or action by means of;” “physical” as “material;” and “interference” as “meddling in or hampering an activity or process.”
2. Reject an extra-textual “affirmative act” requirement. Milazzo argued the State’s theory “hinges on a passive omission” and therefore cannot be “physical interference.” The Court concluded the text does not demand an affirmative act; rather, the statute is satisfied when a defendant carries out the obstructive purpose “by means of” a material barrier.
3. Apply the definition to the evidentiary record under the sufficiency standard. The jury heard officers testify that commands to unlock were given repeatedly and warnings were issued that the window would be broken; video supported that warnings were made and that the arrest proceeded only after the window was punched and the door unlocked from the inside. Taking the State’s evidence as true and drawing reasonable inferences, the Court held a reasonable jury could find Milazzo “used physical interference” by maintaining the locked door as a material impediment to the passenger’s removal and arrest.

Importantly, the Court treated Milazzo’s locked door not merely as an inert circumstance, but as the “means” through which the obstructive purpose could be carried out—i.e., a material barrier kept in place despite direct police orders during an arrest.

C. Impact

This decision meaningfully clarifies (and broadens in practical effect) the reach of § 575.150 in at least four ways:

• Passive conduct can qualify as “using … physical interference.” The Court’s construction supports prosecutions where interference is accomplished by refusal to remove a physical obstacle within the defendant’s control, even without violence or active struggle.
• “Use” focuses on the means, not the motion. The Court’s emphasis on “by means of” signals that the operative question is whether a defendant employed (or maintained) a material impediment to hamper an arrest—not whether the defendant performed a physically aggressive act.
• Vehicle-access scenarios become a clear application point. Refusing to unlock doors, refusing to open windows, or otherwise preventing access to a person being lawfully arrested may now be more readily framed as “physical interference,” provided the State can prove the statutory mental state and purpose.
• Sufficiency review will rarely undo jury inferences in close factual disputes. By re-emphasizing Chaney and Gilmore, the Court signals that once the State introduces evidence of commands, refusal, and a physical barrier affecting officer actions, appellate relief will be difficult where the jury credited the State’s witnesses.

The limiting principles remain those embedded in § 575.150 itself: the State must still prove knowledge (or reason to know) an arrest is occurring and the purpose of preventing officers from effectuating it, along with interference “by using or threatening” violence, physical force, or physical interference. But after Milazzo, “physical interference” is not confined to overt physical acts.

4. Complex Concepts Simplified

• “Sufficient evidence” (appellate review): The appellate court does not decide what it believes happened; it asks whether a reasonable jury could find guilt beyond a reasonable doubt, assuming the jury believed the State’s evidence and drew reasonable inferences from it.
• “De novo” statutory interpretation: The appellate court independently determines what the statute means, without deferring to the trial court’s interpretation.
• “Plain and ordinary meaning”: If a statute does not define a term, courts often use ordinary dictionary meanings, while still reading the words in context.
• “Physical interference” (as used here): Not limited to fighting or grabbing; it can include using a physical object (or maintaining a physical barrier) as the means of hampering officers from completing an arrest.

5. Conclusion

State of Missouri v. Brian V. Milazzo establishes a clear interpretive rule for § 575.150: “using … physical interference” does not require an affirmative, active act. A defendant may commit interfering with an arrest when, with the purpose of preventing an arrest, he uses a material barrier as the means of hampering officers—here, by refusing to unlock a vehicle door during another person’s arrest despite repeated police commands. The decision strengthens the State’s ability to charge obstruction accomplished through nonviolent but materially obstructive conduct, while reinforcing the highly deferential standard governing appellate review of jury verdicts for evidentiary sufficiency.
