What is interference with public duties under PC § 38.15?
Texas Penal Code § 38.15 prohibits criminally negligent interference with peace officers, firefighters, EMS, animal control officers, process servers, and transportation workers performing their duties. It is a Class B misdemeanor — up to 180 days in county jail and a fine up to $2,000.
- With criminal negligence — § 6.03(d)
- A person acts with criminal negligence when he ought to be aware of a substantial and unjustifiable risk that the result will occur. The failure to perceive the risk must constitute a gross deviation from the standard of care that an ordinary person would exercise. This is an objective standard — actual subjective awareness is not required. Criminal negligence is the lowest culpable mental state recognized by the Texas Penal Code, but it still requires a "gross deviation" — ordinary lack of care or simple negligence is not enough. The mens rea distinguishes § 38.15 from § 38.04 evading arrest (which is intent-based) and from § 38.03 resisting arrest (which requires the use of force).
- Interrupts, disrupts, impedes, or otherwise interferes
- The actus reus — the prohibited conduct must "interrupt, disrupt, impede, or otherwise interfere with" the official's duty. The statute lists four overlapping verbs to ensure broad coverage. The Texas Court of Criminal Appeals addressed the scope of these verbs in State v. Mayorga, 901 S.W.2d 943 (Tex. Crim. App. 1995). Mere presence at a scene is not interference; mere disagreement is not interference. The conduct must in fact have impeded or made more difficult the official's ability to perform the protected duty. Standing in an officer's way during an arrest, refusing to move when ordered during a traffic stop, or recording in a manner that physically obstructs an investigation are recurring fact patterns.
- A peace officer / firefighter / EMS / animal control officer / process server / transportation worker
- Section 38.15 enumerates the protected officials. The bulk of cases involve peace officers performing duty or exercising authority — patrol officers at traffic stops, detectives executing search warrants, jail personnel processing arrestees. Firefighters, EMS personnel, animal control officers, process servers, and transportation workers are also protected when performing the enumerated function. The official must in fact be performing the protected duty at the time. An off-duty officer not exercising authority is outside the statute's scope. Identification of the official, knowledge of their status, and the nexus to the protected duty are routine elements that the State must prove.
- Performing a duty or exercising authority
- The interference must occur while the official is in fact performing the protected duty or exercising legal authority. If the officer's underlying conduct is itself unlawful — an unconstitutional stop, an unlawful arrest, an officer exceeding statutory authority — courts have held that the official is not performing a "duty" within the meaning of § 38.15. The defendant's right to refuse cooperation with an unlawful order is a recurring defense theme. The lawfulness analysis can become its own contested trial issue, particularly where the underlying stop or arrest was on shaky Fourth Amendment ground.
- Penalty under § 12.22 — Class B misdemeanor range
- Conviction carries a punishment range of up to 180 days in county jail and a fine up to $2,000. Community supervision (probation) is generally available. First-time offenders frequently resolve the case through pretrial diversion, deferred disposition, or a plea to disorderly conduct (a Class C citation-only offense). The collateral consequences — particularly for defendants with professional licenses, immigration status, or jobs requiring background checks — often exceed the direct criminal exposure, which is why charge negotiation and outcome-shaping in the first 30-60 days are critical.
Texas § 38.15 occupies a structural niche in the Penal Code as the catch-all interference statute. Sections 38.03, 38.04, and 36.06 cover the violent, flight-based, and threat-based interference patterns; § 38.15 captures everything else. That residual scope makes the statute a frequent companion charge in police-encounter cases — where the State cannot prove the force needed for § 38.03 resisting or the flight needed for § 38.04 evading, but believes the defendant's conduct made the encounter materially harder, the State charges § 38.15. The Class B misdemeanor exposure is modest by criminal-court standards, but the statute is regularly used as a leverage charge in plea negotiations, as an add-on count on a DWI or drug case, and as a contempt-of-cop charge in escalating encounters.
The contested element in most § 38.15 prosecutions is the criminal-negligence mens rea. The State must prove that the defendant's failure to appreciate the risk that his conduct would interfere with the officer's duty was a "gross deviation" from the ordinary standard of care. Standing on a sidewalk while officers conducted a traffic stop is not a gross deviation. Refusing an officer's lawful order to step back from an active scene may be — particularly where the defendant was repeatedly warned. The line between protected conduct and culpable interference often turns on the specific officer instructions given, the defendant's compliance posture, and the contemporaneous body-camera record. Defense work in the first 30 days regularly focuses on obtaining and reviewing every available video angle of the encounter, because the visual record usually drives the mens-rea narrative in either direction.
Elements and the criminal negligence mens rea under § 6.03(d)
Section 38.15 requires criminal negligence — the actor ought to have been aware of a substantial and unjustifiable risk, and the failure to perceive it must constitute a gross deviation from the ordinary standard of care. This objective standard distinguishes § 38.15 from intent-based interference offenses.
Criminal negligence under Texas Penal Code § 6.03(d) sits at the bottom of the four-tier mens-rea ladder established by the Penal Code. The other tiers — intentional under § 6.03(a), knowing under § 6.03(b), and reckless under § 6.03(c) — each require some form of subjective awareness or purpose on the part of the actor. Criminal negligence is purely objective. The State does not have to prove that the defendant actually appreciated the risk; the State must prove only that the defendant ought to have appreciated it, and that the failure to appreciate it was a gross deviation from the ordinary standard of care. That makes criminal negligence easier to prove on the awareness element, but it raises the bar on the "gross deviation" element — the failure to perceive the risk must be substantial, not merely a momentary lapse of attention.
The contemporary appellate decisions interpreting § 38.15 build on State v. Mayorga, 901 S.W.2d 943 (Tex. Crim. App. 1995), which addressed the scope of "interference" and the criminal-negligence mens rea in tandem. The Court emphasized that the statute requires more than passive non-cooperation — there must be conduct that actually interrupted, disrupted, impeded, or interfered with the protected duty. A defendant who silently refused to consent to a search did not interfere; a defendant who physically positioned himself between officers and a subject under arrest did. The "ought to have been aware" inquiry in this context turns on whether a reasonable person in the defendant's position — knowing what the defendant knew, including the officers' visible activity and any direct instructions — would have appreciated the risk that the conduct would impede the officer's duty.
Defense work on the criminal-negligence element regularly proceeds along two parallel tracks. First, the defense develops the factual record to show that the defendant did not in fact have notice of the risk — that the officers did not give clear instructions, that the active duty was not visible or was ambiguous, that the defendant complied as soon as the situation was clarified. Second, the defense argues legally that even if the defendant's conduct did impede the officer to some marginal degree, the failure to anticipate that effect was not a "gross deviation" from ordinary care. A bystander who paused to ask a question, who delayed momentarily before moving aside, who did not immediately understand that an order applied to her — these are not gross deviations under Texas appellate law, even where the State has tried to argue otherwise. The combination of factual and legal arguments on mens rea regularly produces dismissals, pretrial diversions, or jury acquittals where the State's case looked plausible on the offense report.
A related strategic point: criminal negligence under § 6.03(d) is the same mens-rea standard that governs § 19.05 criminally negligent homicide — the bottom rung of the Texas homicide ladder. The appellate caselaw developed in the homicide context (notably Tello v. State, 180 S.W.3d 150 (Tex. Crim. App. 2005)) is directly transposable to § 38.15. Defense counsel in interference cases regularly cite the homicide-context decisions for the proposition that ordinary inattention is not criminal negligence, that hindsight cannot create the "gross deviation," and that the State must prove the mens rea by the same standard the law requires for the most serious negligence-based offense in the Code.
The § 38.15(d) speech-only affirmative defense
Section 38.15(d) supplies a textual affirmative defense: interference consisting of speech only is not punishable. Where the only proven conduct is verbal — questioning, criticizing, refusing to consent, narrating to bystanders — the statute itself defeats prosecution.
The Texas Legislature wrote a powerful affirmative defense directly into § 38.15. Subsection (d) provides: "It is a defense to prosecution under this section that the interruption, disruption, impediment, or interference alleged consisted of speech only." The provision is one of the most defendant-favorable affirmative defenses in the Texas Penal Code — it eliminates criminal liability whenever the State's evidence is limited to verbal conduct. The legislative judgment reflected in § 38.15(d) is straightforward: the line between criminal interference and protected expression is the line between physical impediment and verbal commentary, and the statute does not punish citizens for arguing with, questioning, or criticizing public officials performing their duties.
The foundational case applying § 38.15(d) is Fisher v. State, 887 S.W.2d 49 (Tex. App.—Texarkana 1994), which reversed a § 38.15 conviction where the State's evidence showed only that the defendant verbally challenged officers conducting a search. The court held that the speech-only affirmative defense applied as a matter of law because no non-verbal conduct was proved. Fisher remains the workhorse decision and is regularly cited in DFW trial-court briefing to defeat § 38.15 prosecutions where the State's case turns on verbal challenges, refusal to consent, or critical commentary directed at officers.
The affirmative-defense burden under Texas law is a burden of production, not persuasion — the defendant must come forward with some evidence raising the issue, but once raised, the State bears the burden of disproving the defense beyond a reasonable doubt. Practically, this means that if the body-camera record shows that the defendant's only contribution to the encounter was verbal — questioning the basis for the stop, refusing consent, narrating the encounter to bystanders or a recording device, criticizing the officer's decisions — the jury must be charged on the affirmative defense, and the State must persuade the jury beyond a reasonable doubt that there was additional non-verbal interference. Where the body camera does not show physical interference, jury verdicts regularly come back in the defendant's favor.
The interaction between speech-only conduct and other proved conduct is where most contested § 38.15 cases live. The State frequently argues that the defendant's speech accompanied or amplified non-verbal conduct — that the defendant stood in the officer's way and shouted at the officer simultaneously, or that the recording itself crossed from passive observation into active interference. The defense response is fact-specific: parse the body-camera record minute by minute, identify the precise moments at which non-verbal conduct allegedly occurred, and challenge the State to prove that the non-verbal conduct standing alone interfered with the protected duty. Where the State's case is in fact built on the speech with the non-verbal conduct as window dressing, the defense moves for acquittal at the close of evidence, citing Fisher and the plain text of § 38.15(d).
Distinction from § 38.03, § 38.04, and § 36.06
Section 38.15 is the residual interference statute — it captures non-force, non-flight, non-threat conduct that the State cannot charge under § 38.03 resisting arrest, § 38.04 evading arrest, or § 36.06 obstruction or retaliation. The distinguishing elements are force, flight, and threat respectively.
Section 38.03 resisting arrest requires that the defendant intentionally prevent or obstruct a peace officer from effecting an arrest, search, or transportation by using force against the peace officer or another. The force element is the dispositive line. Bare non-cooperation — going limp, refusing to walk, refusing to give one's hands behind the back without affirmative physical resistance — does not satisfy the force element. Pushing, pulling, striking, kicking, or otherwise physically opposing the officer does. Where the State has proof of physical resistance, the charge is § 38.03 (a Class A misdemeanor — up to one year in county jail and a $4,000 fine, twice the exposure of § 38.15). Where the State cannot prove force, the State often falls back on § 38.15 as a leverage charge — but the residual-charge posture is not a substitute for proof of force, and aggressive defense work routinely defeats § 38.15 add-ons where the conduct charged was bare non-cooperation.
Section 38.04 evading arrest or detention requires that the defendant intentionally flee from a peace officer who the defendant knew was lawfully attempting to arrest or detain him. The flight element is the dispositive line. The mens rea is intentional flight — criminal negligence is not enough, and merely walking away or driving away under circumstances where the officer's intent to detain was ambiguous does not satisfy the statute. Section 38.04 is a Class A misdemeanor on its base form (one year + $4,000) but escalates to a state-jail felony when committed with a vehicle and to a third-degree felony with prior convictions or where the flight produced serious bodily injury. Where the conduct charged is non-flight — standing one's ground, refusing to leave the scene, returning to the area after a directive to leave — § 38.04 does not apply, and the State falls back on § 38.15. The distinction matters because § 38.04 is a more serious charge with substantially higher punishment exposure, especially on a vehicular escape.
Section 36.06 obstruction or retaliation requires that the defendant intentionally or knowingly harm or threaten to harm a public servant, witness, prospective witness, informant, or other enumerated person on account of or in retaliation for that person's service or status. The harm-or-threat-of-harm element distinguishes § 36.06 from § 38.15. Section 36.06 is a third-degree felony in its base form (2-10 years in TDCJ and up to a $10,000 fine) — far more serious than the Class B § 38.15. Where the conduct charged does not include actual or threatened harm — where the defendant's alleged interference was non-threatening verbal challenge, passive obstruction, or non-violent resistance — § 36.06 does not apply. The State sometimes attempts to charge § 36.06 on facts that better support § 38.15 (and vice versa); the choice of statute is critical to the case posture, the punishment exposure, and the discovery profile.
Section 38.15 is the residual category that captures the conduct the other statutes do not reach: standing in an officer's way during a traffic stop, refusing to step back at an active scene, recording the encounter at a distance the officer subjectively considers too close, narrating the encounter to bystanders, refusing to leave a public place after being asked, or walking up to ask a question while officers are dealing with another subject. These are the recurring § 38.15 fact patterns. The recurring defense response is to push the case toward the speech-only affirmative defense under § 38.15(d), to challenge the criminal-negligence mens rea on the facts of the encounter, or to argue that the underlying officer conduct was itself unlawful so that the officer was not performing a "duty" within the meaning of the statute.
Defense strategies for § 38.15 prosecutions
Defense work in interference cases focuses on the speech-only affirmative defense, criminal-negligence mens-rea challenges, First Amendment as-applied arguments in recording cases, lawfulness of the underlying officer conduct, and charge negotiation to disorderly conduct or pretrial diversion.
The speech-only affirmative defense under § 38.15(d) is the first line of defense in any case where the State's evidence is meaningfully verbal. The defense reviews every minute of body-camera and dash-cam footage, identifies the precise non-verbal conduct (if any) the State will rely on, and assesses whether the case can be teed up as a speech-only prosecution. Where the answer is yes, the defense files a motion to dismiss or moves for directed verdict at the close of the State's case, citing Fisher v. State, 887 S.W.2d 49 (Tex. App.—Texarkana 1994), and the plain text of § 38.15(d). Even where some non-verbal conduct exists, the defense develops the record to show that the non-verbal component was de minimis and that the State's case is in substance a speech-only prosecution dressed up with marginal physical conduct.
The criminal-negligence challenge is the second line. The State must prove that the defendant's failure to appreciate the risk of interference was a gross deviation from the ordinary standard of care. Defense work develops the factual record to show that the officer's instructions were unclear, that the defendant complied as soon as the situation was clarified, that the alleged interference was momentary and non-substantial, or that the defendant was actively trying to help — administering aid, retrieving identification, separating from a conflict — rather than impede. The "gross deviation" requirement is a meaningful legal hurdle for the State, and well-developed defense factual records regularly produce dismissals, pretrial diversions, or jury acquittals on mens-rea grounds even where the State has body-camera proof of physical presence at the scene.
In recording-police cases, the defense layers a First Amendment as-applied challenge on top of the statutory defenses. Turner v. Driver, 848 F.3d 678 (5th Cir. 2017), established that the right to record police performing public duties in public places is clearly established law in the Fifth Circuit. The defense argues that the prosecution itself is constitutionally infirm because it punishes conduct that the First Amendment protects. The argument is fact-specific — recording at a reasonable distance without physical interference is constitutionally protected, while physical obstruction of an investigation is not — but the constitutional overlay creates a powerful defense theme in recording-related interference cases that the State must contend with at every stage from charge negotiation through trial.
A separate defense theme is the lawfulness of the underlying officer conduct. Section 38.15 protects officers who are in fact performing a "duty" — if the underlying stop, arrest, or other officer action was itself unlawful, the officer was not performing a protected duty within the meaning of the statute. The defense develops the Fourth Amendment record on any contested stop or arrest, files motions to suppress, and argues that the lawfulness of the underlying officer conduct is itself an element the State must prove. Where the underlying stop or arrest fails on Fourth Amendment grounds, the § 38.15 charge collapses with it.
Charge negotiation regularly produces outcomes well below the statutory maximum. The most common negotiated resolutions are: a plea to disorderly conduct under § 42.01 (a Class C misdemeanor punishable by fine only, citation-equivalent), pretrial diversion (charge dismissed after a probationary period without conviction), deferred disposition (similar but with a court-supervised period), or outright dismissal. Defense work in the first 30-60 days — identifying the speech-only defense, marshaling the body-camera record, building a mitigation packet on the defendant's background — shapes the negotiation posture and often produces a non-conviction resolution before any contested motion practice is needed.
First Amendment overlay — Turner v. Driver and recording police
The Fifth Circuit's 2017 decision in Turner v. Driver established that the First Amendment protects the right to record police performing public duties in public places. This constitutional overlay shapes § 38.15 prosecutions involving citizen recording in DFW courts.
In Turner v. Driver, 848 F.3d 678 (5th Cir. 2017), the Fifth Circuit held that the First Amendment protects the right of private citizens to record police officers engaged in their official duties in public places, subject to reasonable time, place, and manner restrictions. The court reached the merits in a § 1983 qualified-immunity context and concluded both that the right exists and that it was clearly established for qualified-immunity purposes within this circuit. The decision joined the First, Third, Seventh, Ninth, and Eleventh Circuits in recognizing the recording right and created a binding rule for federal-court actions arising in Texas, Louisiana, and Mississippi.
Although Turner is a § 1983 decision rather than a criminal case, its rule directly affects § 38.15 prosecutions where the alleged interference consisted of recording. The First Amendment imposes a constitutional ceiling on § 38.15 — the statute cannot constitutionally be applied to punish conduct that the First Amendment protects. Where the defendant's recording was at a reasonable distance, did not physically obstruct the officers, and did not exceed the scope of conduct that Turner protects, the prosecution faces an as-applied constitutional challenge that operates independently of the statutory defenses. The defense files a motion to dismiss the indictment or to quash the complaint on First Amendment grounds, marshals the body-camera record to show the recording posture, and argues that the prosecution itself is constitutionally infirm.
The interaction between Turner, the § 38.15(d) speech-only defense, and the criminal-negligence mens rea creates a robust three-layer defense framework for recording-police cases. Layer one is constitutional: the conduct is constitutionally protected. Layer two is statutory: if the State's evidence is verbal commentary or recording without physical interference, the § 38.15(d) affirmative defense defeats prosecution. Layer three is mens rea: the State must prove that the defendant's failure to appreciate the risk of interference was a gross deviation from the ordinary standard of care, which is a difficult showing where the defendant was exercising a constitutionally protected right at a reasonable distance. Each layer is independently sufficient to defeat the charge, and the State must overcome all three to obtain a conviction.
Carney v. State, 31 S.W.3d 392 (Tex. App.—Austin 2000), is a Texas appellate decision addressing § 38.15 in a recording context that predates Turner but remains relevant to fact analysis. The court there examined the line between protected observation and culpable interference, focusing on the proximity of the recording, the directness of the officer's instructions, and the defendant's compliance posture. The combination of Carney's fact-driven analysis and Turner's constitutional framework supplies the defense roadmap in any DFW recording-police prosecution. The State's burden post-Turner is substantially heavier than it was before 2017, and many recording-police § 38.15 prosecutions that survived in DFW courts a decade ago would no longer reach the jury today.
Local DFW practice considerations
Section 38.15 prosecutions in Collin, Dallas, Denton, and Tarrant counties typically resolve through plea-to-disorderly-conduct, pretrial diversion, deferred disposition, or outright dismissal. Trial work focuses on body-camera review, mens-rea development, and the speech-only affirmative defense.
In Collin County, where many of our § 38.15 cases originate, the County Court at Law dockets handle Class B misdemeanors. The DA's misdemeanor division regularly negotiates plea-to-disorderly-conduct resolutions or pretrial diversion in § 38.15 cases where the defendant has no significant prior record and the underlying encounter was non-violent. Frisco PD, Plano PD, McKinney PD, and the Collin County Sheriff's Office are the primary law enforcement agencies whose body-camera and dash-cam records drive these prosecutions. Plano and Frisco both operate robust body-camera programs, and the visual record on a typical § 38.15 encounter is comprehensive — usually multiple camera angles, often with audio from multiple officers. Defense work in Collin County frequently turns on early production of that record and the corresponding mens-rea narrative it supports.
In Dallas County, the County Criminal Courts handle Class B misdemeanors with a separate intake process for police-encounter cases. The Dallas DA's office has historically been more willing to dismiss or divert § 38.15 cases where the record supports a speech-only theory or where the underlying officer conduct is itself contested. Dallas PD and the Dallas County Sheriff's Office are the primary agencies. Dallas operates a body-camera program with comprehensive policies on recording during arrests and stops. Defense counsel in Dallas County § 38.15 cases regularly use the body-camera record to support a motion to dismiss based on the speech-only defense or on insufficient criminal negligence.
In Denton County, the County Court at Law dockets handle Class B misdemeanors and the DA's misdemeanor division operates a pretrial diversion program that frequently captures first-time § 38.15 defendants. Denton PD, Lewisville PD, Frisco PD (parts of Frisco fall in Denton County), and the Denton County Sheriff's Office are the primary agencies. The DA's office in Denton has historically been receptive to diversion and disposition pleas where the defendant has no prior record and the encounter was non-violent. Defense work in Denton frequently focuses on building the mitigation packet — employment, education, community ties, treatment history — that supports a non-conviction resolution.
In Tarrant County, the County Criminal Courts handle Class B misdemeanors and the DA's misdemeanor division has historically taken a more aggressive posture on § 38.15 cases, particularly those arising from protest or demonstration activity. Fort Worth PD, Arlington PD, and the Tarrant County Sheriff's Office are the primary agencies. Trial postures are somewhat more common in Tarrant than in the other three counties, and defense counsel regularly develop the full evidentiary record on the body-camera, the mens-rea narrative, and the First Amendment overlay (where applicable) in preparation for contested motion practice and trial.
Across all four counties, the bond posture on a § 38.15 arrest is generally manageable — personal recognizance or low cash bonds in the $500-$1,500 range are typical. Pretrial release conditions vary by judge but often include standard conditions like no contact with complainants (rarely applicable in § 38.15 cases since the "complainant" is the officer), no consumption of alcohol while on bond, and travel restrictions. Defense counsel can usually move quickly to favorable resolutions because the underlying charge is modest, the State's case usually depends on a manageable body-camera record, and the affirmative-defense and mens-rea defenses give defense counsel substantial negotiating leverage early in the case.
When to retain counsel for a § 38.15 charge
Retain counsel immediately on any § 38.15 arrest or notice of investigation. Class B misdemeanor exposure is modest, but the collateral consequences — professional licenses, immigration status, background checks — often exceed the criminal exposure, and early defense work shapes the outcome.
Section 38.15 charges typically arise out of contentious police encounters where multiple charges or potential charges are in play — DWI investigations that produced interference allegations, drug-possession arrests with companion interference counts, domestic-violence calls where the alleged interference is intertwined with the underlying allegations. The interaction between the § 38.15 count and the other charges shapes the entire defense posture. A defendant facing a DWI with a companion § 38.15 needs counsel who can develop both defenses simultaneously and who understands how the body-camera record drives both theories.
Collateral consequences are often the most consequential aspect of a § 38.15 conviction. Professional licenses — nursing, teaching, real estate, insurance, financial services — frequently require disclosure of any criminal conviction, including misdemeanors. Immigration consequences for non-citizens depend on the specific charge and the resolution; while § 38.15 is not a categorical crime of moral turpitude or an aggravated felony, the conviction record is reviewed in subsequent immigration proceedings. Employment background checks at major DFW employers regularly identify Class B misdemeanors. A non-conviction resolution — pretrial diversion, deferred disposition, dismissal, plea to disorderly conduct — substantially mitigates these collateral consequences and is the typical defense objective.
The first 30 days after arrest or notice of investigation are the most consequential for case outcome. Body-camera and dash-cam records have retention periods that vary by agency; defense counsel issues written preservation demands immediately to lock down the visual record before any agency-driven deletion. Witness statements, defendant-side video (the defendant's own phone recording is often the most favorable evidence), and 911 audio are also subject to preservation demands. The mens-rea narrative is largely built or lost in this window — the visual and testimonial record either supports the criminal-negligence theory or undercuts it, and the contemporaneous evidence collected in the first 30 days is what defense counsel will rely on for the next 6-12 months of case work.
Defendants who attempt to handle a § 38.15 charge without counsel — pleading guilty at the first appearance, accepting an initial DA offer, declining to challenge the underlying officer conduct — frequently produce outcomes that are substantially worse than what counsel could have negotiated. The Class B exposure is modest, but the conviction record is real, and the collateral consequences accumulate over years. Retaining experienced criminal-defense counsel on any § 38.15 arrest — at any point in the case but especially in the first 30 days — is the single most important step in protecting the long-term outcome.
