10.1 Domestic Violence Mandatory Arrest (C.R.S. § 18-6-803.6) & Colorado Crime Victim Rights Act

Key Takeaways

  • Domestic violence under C.R.S. § 18-6-800.3 is not an independent substantive crime in Colorado; it is a statutory sentence enhancer attached to an underlying crime committed against an intimate partner for coercion, control, punishment, intimidation, or revenge.
  • Under C.R.S. § 18-6-803.6, peace officers with probable cause that a domestic violence crime occurred have a non-discretionary mandatory duty to arrest the predominant aggressor; issuing a summons or citation in lieu of physical custodial arrest is strictly prohibited.
  • Colorado law strongly disfavors dual arrests; officers must conduct a predominant aggressor analysis evaluating prior domestic violence complaints, relative severity of injuries, likelihood of future harm, self-defense claims, and coercive control dynamics.
  • Mandatory Protection Orders (MPOs) under C.R.S. § 18-1-1001 automatically attach upon criminal arraignment, prohibiting contact, weapons possession, and alcohol/drug use; officers have a mandatory arrest duty upon probable cause of any MPO violation under C.R.S. § 18-6-803.5.
  • The Colorado Crime Victim Rights Act (C.R.S. Title 24, Article 4.1) mandates written victim rights advisement on-scene, case updates across all critical stages, and protection of victim safety, while C.R.S. § 18-6.5-108 imposes mandatory 24-hour reporting for suspected abuse of at-risk elders (70+) and at-risk adults.

Domestic Violence Mandatory Arrest & Colorado Crime Victim Rights Act

Domestic violence investigations represent some of the most volatile, legally constrained, and procedurally demanding incidents encountered by Colorado peace officers. The Colorado General Assembly has enacted comprehensive statutory frameworks designed to remove police discretion in favor of victim safety, deter perpetrator retaliation, and guarantee trauma-informed procedural protections. Understanding the precise statutory definitions of intimate relationships, executing the mandatory arrest statute under C.R.S. § 18-6-803.6, conducting rigorous predominant aggressor determinations, enforcing Mandatory Protection Orders under C.R.S. § 18-1-1001, and fulfilling the affirmative duties of the Colorado Crime Victim Rights Act (VRA) are core competencies tested on the Colorado POST Peace Officer Certification Exam.


1. Statutory Definition & Nature of Domestic Violence (C.R.S. § 18-6-800.3)

In Colorado criminal jurisprudence, domestic violence is not a standalone substantive criminal charge. An individual cannot be charged simply with "Domestic Violence." Instead, domestic violence functions as a statutory sentence enhancer and sentence modifier attached to any underlying Title 18 felony, misdemeanor, or petty offense, or municipal ordinance violation.

A. Definition of Domestic Violence (C.R.S. § 18-6-800.3(1))

Under C.R.S. § 18-6-800.3(1), Domestic Violence means:

"An act or threatened act of violence upon a person with whom the actor is or has been involved in an intimate relationship. 'Domestic violence' also includes any other crime against a person, or against property, including an animal, or any municipal ordinance violation against a person, or against property, including an animal, when used as a method of coercion, control, punishment, intimidation, or revenge directed against a person with whom the actor is or has been involved in an intimate relationship."

Key Elements of the Definition:

  1. Violence or Threatened Violence: Any intentional, knowing, or reckless infliction or threat of physical harm against an intimate partner.
  2. Crimes Against Property: Damaging, defacing, or destroying property (e.g., smashing the partner's cell phone, punching a hole in their bedroom wall, slashing car tires) constitutes criminal mischief with a domestic violence sentence enhancement if done to punish, intimidate, or coerce the intimate partner.
  3. Crimes Against Animals: Injuring, killing, or threatening an intimate partner's pet or emotional support animal (Cruelty to Animals under C.R.S. § 18-9-202) to exert coercive control or revenge constitutes domestic violence.
  4. Coercive Control Dynamics: Crimes such as False Imprisonment (C.R.S. § 18-3-303), Wiretapping / Telephone Tampering (C.R.S. § 18-9-111(1)(e)), or Reckless Endangerment (C.R.S. § 18-3-208) are classic domestic violence offenses when used to dominate or terrorize an intimate partner.

B. Definition of Intimate Relationship (C.R.S. § 18-6-800.3(2))

Under Colorado law, an Intimate Relationship is strictly defined as a relationship between:

  • Spouses (currently married);
  • Former spouses (divorced or legally separated);
  • Unmarried couples who are currently in, or were formerly involved in, a dating or romantic/sexual relationship; or
  • Persons who are both the biological/legal parents of the same child, regardless of whether they were ever married or ever cohabited at any point.
Relationship TypeIntimate Relationship under C.R.S. § 18-6-800.3?Statutory Legal Rationale
Current or Former SpousesYESExplicitly enumerated by statute.
Current or Former Dating PartnersYESUnmarried romantic/dating relationship (cohabitation not required).
Parents of a Child in CommonYESBiological or legal coparents; marriage or cohabitation is irrelevant.
Roommates / Non-Dating HousematesNOPurely financial, platonic, or shared residential living is not intimate.
Siblings (Brother / Sister)NOConsanguinity/family relationship alone does not establish intimate relationship.
Parent and Child (Adult or Minor)NOGoverned by child abuse or elder abuse statutes, not domestic violence (unless coparents).
Casual Acquaintances / FriendsNOLacks the romantic, sexual, or dating nexus required by Colorado law.

2. Colorado Mandatory Arrest Statute (C.R.S. § 18-6-803.6)

Colorado is a strict mandatory arrest state for domestic violence. Peace officers do not possess field discretion to issue warnings, mediate verbal agreements, separate parties for the night without an arrest, or issue a summons and complaint when probable cause exists.

Statutory Provisions of C.R.S. § 18-6-803.6(1)

When a peace officer determines there is probable cause to believe that a crime or violation of a municipal ordinance has been committed involving domestic violence, the officer shall arrest the person without undue delay. The officer's duty is mandatory and triggered by the existence of probable cause, regardless of:

  • Whether the victim desires prosecution;
  • Whether the victim refuses to provide a written statement or sign a complaint;
  • Whether the suspect has left the scene (officers must write an arrest warrant affidavit if suspect cannot be located);
  • The time elapsed since the incident, provided the applicable statute of limitations has not expired.

No-Bond Hold and First Appearance

Following a domestic violence arrest, the suspect cannot be released on a standard pre-set bond schedule at the jail. The suspect must be held in custody without bond until brought before a county court judge or magistrate for an initial appearance/arraignment, where the court advises the defendant of the Mandatory Protection Order (MPO) under C.R.S. § 18-1-1001.


3. Predominant Aggressor Analysis & Dual Arrest Prohibition (C.R.S. § 18-6-803.6(2))

Historical police practices of arresting both parties ("dual arrest") when both present minor injuries severely undermined victim trust, revictimized battered individuals, and impeded successful prosecution. Colorado statute explicitly discourages dual arrests.

Statutory Mandate (C.R.S. § 18-6-803.6(2)): "When complaints are received from two or more opposing persons, the officer shall evaluate each complaint separately to determine who was the predominant aggressor. If the officer determines that one person was the predominant aggressor, the officer need not arrest the other person even though the officer has probable cause to believe that the other person committed a crime."

The Predominant Aggressor Determination Matrix

To identify the predominant aggressor, peace officers must thoroughly investigate and document the following six statutory and tactical criteria:

Assessment FactorInvestigative Analysis & Evidence Collection
1. Prior History of DVReview CCIC/NCIC, local CAD call logs, historical protection orders, and prior arrest records for patterns of abuse, stalking, or violence.
2. Relative Severity of InjuriesDifferentiate offensive injuries (closed-fist knuckle contusions, blunt trauma, strangulation ligature marks) from defensive injuries (scratch marks on suspect's neck/face, bite marks on suspect's inner arm, forearm bruising).
3. Likelihood of Future HarmAssess which party poses the genuine, ongoing physical danger and lethality threat to the household.
4. Lawful Self-Defense (C.R.S. § 18-1-704)Determine whether one party used physical force reasonably necessary to defend themselves or a child against the imminent use of unlawful physical force by the other party. Force used in self-defense is lawful and cannot be the basis for arrest.
5. Witness & 911 Audio EvidenceAnalyze excited utterances on initial 911 recordings, independent neighbor/child statements, surveillance footage, and property damage trajectory.
6. Coercive Control & Fear DemeanorEvaluate which party exhibits dominant, controlling, entitled demeanor versus submissive, terrified, traumatized, or hyper-vigilant responses.

Dual Arrest Reporting Requirement

If an officer cannot determine a predominant aggressor and establishes separate probable cause against both parties resulting in a dual arrest, the officer must draft a comprehensive narrative in the police report explicitly articulating why a predominant aggressor could not be determined. Department command staff and prosecutors closely scrutinize dual arrest reports.


4. Mandatory Protection Orders (MPO) under C.R.S. § 18-1-1001

Under C.R.S. § 18-1-1001, a Mandatory Protection Order (MPO) is automatically entered against every criminal defendant charged with any Title 18 criminal offense or municipal ordinance violation upon the defendant's initial appearance before the court. In domestic violence cases, the MPO serves as the primary judicial restraining mechanism.

│   coming within a specified distance of the victim's home, workplace, school.│
│ • FIREARMS SURRENDER (§ 18-1-1001(9) / § 13-14-105.5): Mandates surrender of│
│   all firearms and ammunition within 24 hours of release from custody.      │
│ • SOBRIETY MONITORING: Prohibits the possession and consumption of alcohol │
│   and controlled substances (when ordered by the magistrate/judge).         │
└─────────────────────────────────────────────────────────────────────────────┘

Violation of Protection Order (C.R.S. § 18-6-803.5)

Violating a criminal or civil protection order is a distinct criminal offense under C.R.S. § 18-6-803.5.

  • Classification: Class 1 Misdemeanor (or Class 2 Misdemeanor for certain non-violent municipal orders; Class 1 Misdemeanor with mandatory consecutive sentencing if underlying case involves domestic violence; elevated to a Class 6 Felony if defendant has two or more prior convictions for protection order violation).
  • Mandatory Arrest Duty (C.R.S. § 18-6-803.5(3)): Whenever a peace officer has probable cause to believe that a person has violated a valid protection order (verified through CCIC/NCIC, court records, or physical copy), the officer shall arrest the restrained person without delay. The officer has zero discretion to issue a warning or allow the restrained person to leave voluntarily.
  • Consent Defense Precluded: An MPO is an order of the court, NOT an agreement between the parties. Even if the protected victim invites the defendant back home, sends affectionate text messages, or grants explicit permission to meet, the defendant remains in criminal violation of the MPO. The victim lacks legal authority to modify or waive a court order.

5. Colorado Crime Victim Rights Act (VRA - C.R.S. Title 24, Article 4.1)

The Colorado Crime Victim Rights Act (VRA), codified at C.R.S. § 24-4.1-301 through § 24-4.1-304 and grounded in Article II, Section 16a of the Colorado Constitution, guarantees comprehensive legal rights to victims of specified violent and person-focused crimes.

A. Covered Crimes Under the VRA

VRA statutory rights automatically apply to victims of enumerated crimes, including:

  • All domestic violence offenses (any crime with DV enhancement);
  • Homicide, vehicular homicide, and manslaughter;
  • First, Second, and Third-Degree Assaults;
  • Menacing, Kidnapping, Robbery, and Stalking;
  • Sexual assaults and unlawful sexual contact;
  • Child abuse (C.R.S. § 18-6-401) and human trafficking;
  • Bias-motivated crimes (C.R.S. § 18-9-121);
  • Crimes against at-risk elders and at-risk adults.

B. Law Enforcement On-Scene & Ongoing Mandatory Obligations

Critical StageStatutory Law Enforcement Mandates under C.R.S. § 24-4.1-302.5 / 303
Initial On-Scene Contact• Provide the official agency Victim Rights Pamphlet containing statutory rights.<br/>• Provide law enforcement case report number, agency name, investigating officer's name, and contact telephone number.<br/>• Provide emergency contact info for local domestic violence safehouses, victim advocacy crisis lines, and medical resources.
Arrest & Custody Status• Promptly notify the victim when a suspect has been arrested, taken into custody, or issued an arrest warrant.<br/>• Notify the victim of the suspect's initial bond hearing date, bond amount, and conditions of release.
Property Return• Expeditiously return personal property seized as evidence when no longer critically needed for prosecution (taking photographs to substitute for physical items where feasible).
Victim Safety & Confidentiality• Inform victim of the Colorado Address Confidentiality Program (ACP) for victims of DV, stalking, and sexual assault.<br/>• Inform victim of eligibility for Crime Victim Compensation (medical, counseling, lost wage reimbursement).
Dignity and Respect• Treat victims with fairness, dignity, and respect, free from intimidation, harassment, or retaliation throughout all phases of the investigation.

6. Protection of At-Risk Adults and Elders (C.R.S. § 18-6.5-101 et seq.)

Colorado statutory law establishes strict protections, enhanced criminal classifications, and mandatory reporting requirements for vulnerable adult populations.

A. Statutory Definitions (C.R.S. § 18-6.5-102)

  • At-Risk Elder: Any person who is seventy (70) years of age or older.
  • At-Risk Adult with a Disability: Any person eighteen (18) years of age or older who has a physical, intellectual, or developmental disability, or mental illness, that significantly impairs their ability to independently provide for their daily care, personal safety, or protection.
  • At-Risk Juvenile: Any person under the age of eighteen (18) who has a disability as defined by statute.

B. Mandatory Reporting (C.R.S. § 18-6.5-108)

Colorado law mandates that designated professionals who observe or receive a report of mistreatment, self-neglect, or financial exploitation of an at-risk elder or at-risk adult must make a report to a law enforcement agency within twenty-four (24) hours.

  • Mandatory Reporters: Peace officers, physicians, nurses, emergency medical personnel, social workers, long-term care ombudsmen, and financial institution personnel (bank tellers, financial advisors).
  • Failure to Report: A mandatory reporter who willfully fails to report suspected abuse commits a Class 2 Misdemeanor.

C. Enhanced Criminal Penalties (C.R.S. § 18-6.5-103)

Under C.R.S. § 18-6.5-103, committing specified crimes against an at-risk person substantially enhances the penalty classification:

  • Assault Against At-Risk Person: Assault in the third degree committed against an at-risk elder/adult elevates from a Class 1 Misdemeanor to a Class 5 Felony.
  • Theft from At-Risk Person: Theft of property or money from an at-risk person elevates by one full felony class above standard theft value thresholds.
  • Caretaker Neglect & Exploitation: Knowingly neglecting, physically abusing, or financially exploiting an at-risk person constitutes a Class 3, 4, or 5 Felony depending on the value or degree of injury.
