1.1 The Colorado Criminal Justice System & Criminal Process
Key Takeaways
- POST Unit I.A allots 4 required hours to the criminal process, and its first performance outcome is applying the First, Fourth, Fifth, Sixth, Eighth and Fourteenth Amendments to peace officer conduct.
- Colorado's felony case flow runs arrest or summons, Rule 5 advisement, filing of the information or complaint, preliminary hearing where available, arraignment, trial, and sentencing.
- A preliminary hearing is available as of right only for class 1, 2 and 3 felonies and for specified level 1 drug felonies and mandatory-sentence offenses; most class 4 through 6 felonies get no preliminary hearing unless the defendant is in custody.
- Colorado's speedy trial clock in C.R.S. 18-1-405 is six months from the entry of a not guilty plea, not from the date of arrest.
- The general felony statute of limitation in C.R.S. 16-5-401 is three years; misdemeanors are eighteen months and petty offenses six months, with murder, kidnapping, treason, forgery and certain sex offenses having no limitation.
The Colorado Criminal Justice System & Criminal Process
The Colorado POST Basic Academic Training Program opens with Unit I, Introduction to Criminal Justice, and its first sub-topic — I.A Criminal Process, 4 required hours — is not a civics lecture. Its stated general learning goal is that "the student will learn the functions of the criminal justice system in protecting the constitutional rights of all individuals within the United States, regardless of citizenship," and its first specific performance outcome requires the recruit to apply the First, Fourth, Fifth, Sixth, Eighth and Fourteenth Amendments to the actions and conduct of peace officers. Everything a Colorado officer does downstream — a Stone stop, a warrant affidavit, a Miranda advisement, a use-of-force decision — is graded against that constitutional framework, and the certification examination tests it as applied doctrine rather than as memorized text.
1. The Three Components of the System
Colorado's criminal justice system is conventionally described as three interlocking components, and the officer sits at the front door of all three.
| Component | Colorado actors | Officer's dependency |
|---|---|---|
| Law enforcement | Municipal police, county sheriffs, Colorado State Patrol, CBI, DAs' investigators, tribal and federal partners | Generates the case: contact, probable cause, evidence, report |
| Adjudication | Municipal courts, county courts, district courts, Court of Appeals, Colorado Supreme Court; 22 elected district attorneys across Colorado's 23 judicial districts | Consumes the report; every defect in the officer's paperwork becomes a suppression or dismissal issue |
| Corrections | County jails, Department of Corrections, community corrections, probation, parole, Division of Youth Services | Receives the defendant; officers testify at revocation and sentencing hearings |
The practical exam point is discretion. The officer exercises the widest and least reviewable discretion in the entire system — the decision to contact, to cite, to arrest, or to walk away. That is precisely why Colorado layers statutory duties (mandatory domestic violence arrest under C.R.S. 18-6-803.6), constitutional limits, and POST accountability rules on top of it.
2. Constitutional Anchors POST Expects You to Apply
| Amendment | Core protection | Everyday patrol application |
|---|---|---|
| First | Speech, press, assembly, petition, free exercise | Recording police in public; protest management under C.R.S. 24-31-905 |
| Fourth | Unreasonable searches and seizures; warrants on probable cause | Every stop, frisk, search, and arrest |
| Fifth | Self-incrimination, double jeopardy, due process, grand jury | Miranda; custodial interrogation; compelled statements |
| Sixth | Counsel, speedy and public trial, confrontation, jury | Post-filing lineups; Massiah limits on questioning a charged defendant |
| Eighth | Excessive bail and fines; cruel and unusual punishment | Conditions of custody; deliberate indifference to medical need |
| Fourteenth | Due process and equal protection against the states | Applies the Bill of Rights to Colorado officers; anti-bias policing |
Colorado layers its own Article II Bill of Rights on top. Article II, Section 7 is the state search-and-seizure clause and has been read more protectively than the Fourth Amendment in several Colorado decisions, and Article II is the basis for the civil action in C.R.S. 13-21-131 where qualified immunity is not a defense.
3. The Colorado Case Flow
CONTACT ──> ARREST or SUMMONS ──> BOOKING / BOND ──> RULE 5 ADVISEMENT (48 hrs if in custody)
|
└──> FILING: Felony Complaint (county ct.) or Information (district ct.); Misdemeanor Complaint
|
├──> PRELIMINARY HEARING (only where authorized) ──> BINDOVER
|
└──> ARRAIGNMENT (plea entered) ──> SPEEDY TRIAL CLOCK STARTS (6 months)
|
├──> MOTIONS: suppression (4th/5th Am.), Crim. P. 16 discovery
└──> TRIAL (proof beyond a reasonable doubt) ──> VERDICT ──> SENTENCING
Charging instruments. A felony begins on a complaint in county court or by information filed directly in district court; a grand jury indictment is available but uncommon outside statewide and multi-jurisdictional cases. Misdemeanors and petty offenses proceed on a complaint or on the officer's summons and complaint — the citation itself is the charging document, which is why a sloppy citation is a dismissal.
Advisement. Under Crim. P. 5, a person arrested without a warrant must be brought before a judge without unnecessary delay, and Colorado practice requires a judicial probable cause determination within 48 hours of a warrantless arrest, consistent with County of Riverside v. McLaughlin, 500 U.S. 44 (1991). The officer's warrantless-arrest affidavit is what the judge reads at that hearing.
Preliminary hearing. This is a high-yield exam distinction. Under C.R.S. 16-5-301 and Crim. P. 7(h), a preliminary hearing is available as a matter of right for class 1, 2 and 3 felonies, level 1 drug felonies, and any felony carrying a mandatory sentence or charged as a crime of violence or sexual offense. For most class 4, 5 and 6 felonies the defendant gets a preliminary hearing only if in custody for the offense. The standard is probable cause, not proof beyond a reasonable doubt, and hearsay through the case officer is expressly permitted — which is why patrol officers are routinely subpoenaed to testify to another officer's observations.
4. Deadlines the Officer Must Protect
| Clock | Rule | Trigger | Length |
|---|---|---|---|
| Judicial probable cause review | Riverside / Crim. P. 5 | Warrantless arrest | 48 hours |
| Speedy trial | C.R.S. 18-1-405 | Entry of a not guilty plea, not arrest | 6 months |
| Felony limitation | C.R.S. 16-5-401 | Commission of the offense | 3 years (general) |
| Misdemeanor limitation | C.R.S. 16-5-401 | Commission of the offense | 18 months |
| Petty offense limitation | C.R.S. 16-5-401 | Commission of the offense | 6 months |
| No limitation | C.R.S. 16-5-401 | Murder, kidnapping, treason, forgery, and specified sex offenses | None |
Recruits routinely miss the speedy trial trigger. The six-month period runs from arraignment, so a case that sat uncharged for a year is not automatically dead; the statute of limitation, not the speedy trial statute, governs staleness.
5. Burdens of Proof on the Continuum
| Standard | Rough certainty | Where the officer meets it |
|---|---|---|
| Hunch / curiosity | none | Consensual contact only — no seizure permitted |
| Reasonable suspicion | articulable facts | Stone/Terry investigatory stop and frisk |
| Probable cause | fair probability | Arrest, search warrant, charging |
| Preponderance | >50% | Civil actions; some suppression sub-issues |
| Clear and convincing | high probability | POST untruthfulness findings under C.R.S. 24-31-305(2.5) |
| Beyond a reasonable doubt | near certainty | Conviction at trial |
The examination frequently pairs a fact pattern with a request for the lowest standard that authorizes the described action. Read for the action, then match the standard.
A Colorado officer makes a warrantless felony arrest at 2200 hours on a Friday for second degree burglary, a class 4 felony. The defendant remains in custody. Which statement most accurately describes the defendant's preliminary hearing entitlement and the constitutional deadline for judicial review of the arrest?
An officer takes a report of a felony theft that occurred four years earlier and a misdemeanor criminal mischief that occurred one year earlier. Under C.R.S. 16-5-401, what is the correct assessment?
