The Montana Criminal Process — Step by Step
From arrest through sentencing — how a criminal case moves through the Montana court system.
Stage 1: Arrest §46-6-311
A criminal case begins with an arrest — either with a warrant issued by a judge based on probable cause, or without a warrant when an officer witnesses a crime or has probable cause to believe a Felony has been committed §46-6-311. Officers may arrest without a warrant for felonies on probable cause and for misdemeanors committed in their presence. Mont. Code Ann. § 46-6-311 governs warrantless felony arrest.
At the moment of arrest, your constitutional rights attach:
- You have the right to remain silent
- You have the right to an attorney
- Anything you say can and will be used against you
Stage 2: Booking and initial appearance
After arrest, you are booked (photographed, fingerprinted, personal information recorded) and brought before a judge or magistrate for an initial appearance.
At the initial appearance, the judge:
- Informs you of the charges
- Advises you of your rights, including the right to counsel
- Sets bail or conditions of release
- Appoints counsel if you cannot afford an attorney
Stage 3: Bail and pretrial release §46-9-102 et seq.
All persons are bailable before conviction, except when death is a possible punishment for the offense charged and the proof is evident or the presumption great that the person is guilty; at a bail hearing on a capital charge, the state bears that burden. Under § 46-9-108, the court may not impose an unreasonable condition that results in pretrial detention and must use the least restrictive condition or combination of conditions that will ensure the defendant's appearance and protect any person or the community.
Bail is the mechanism that allows you to be released from custody while your case is pending. The amount and conditions are set by the judge based on:
- The seriousness of the charges
- Your criminal history
- Flight risk (ties to the community, employment, family)
- Public safety considerations
Violating bail conditions — including no-contact orders, curfews, drug/alcohol restrictions, or travel limitations — can result in immediate arrest and revocation of bail.
Stage 4: Grand jury / preliminary hearing
Depending on the charge and the jurisdiction, the next step may be a grand jury indictment or a preliminary hearing. Both serve to determine whether there is sufficient evidence (probable cause) to proceed with formal charges.
- [def:grand jury|Grand jury]: A group of citizens reviews evidence presented by the prosecution and decides whether to issue an indictment. The defense does not participate in grand jury proceedings.
- [def:preliminary hearing|Preliminary hearing]: A judge reviews evidence in an open hearing where the defense can cross-examine witnesses. This hearing may reveal the strength of the prosecution's case.
Stage 5: Arraignment
At Arraignment, the formal charges are read, and you enter a plea:
- Not guilty — Preserves all options and is the standard plea at this stage
- Guilty — Waives your right to trial and proceeds to sentencing
>Note: Montana does not allow nolo contendere (no contest) pleas.
Stage 6: Discovery and pretrial motions
After arraignment, both sides exchange evidence (discovery). The defense may file pretrial motions, including:
- Motion to suppress — Asking the court to exclude evidence obtained through illegal searches, coerced confessions, or other constitutional violations
- Motion to dismiss — Arguing that the charges should be dropped due to insufficient evidence, procedural defects, or violations of the defendant's rights
- Motion for change of venue — Requesting the trial be moved if pretrial publicity has made a fair trial impossible in the current jurisdiction
Stage 7: Plea negotiations
The vast majority of criminal cases — approximately 90-95% — resolve through plea negotiations rather than trial. Plea bargaining may result in:
- Reduced charges (e.g., felony reduced to misdemeanor)
- Dismissed counts (if multiple charges)
- Agreed-upon sentencing recommendations
- Diversion or deferred adjudication programs
A plea is a serious decision that should only be made after reviewing all the evidence and understanding the consequences. You have the right to reject any plea offer and proceed to trial.
Stage 8: Trial
If the case proceeds to trial, the prosecution must prove guilt beyond a reasonable doubt. In Montana, a criminal jury consists of 12 members who must reach a unanimous verdict.
The trial proceeds in this order:
Stage 9: Sentencing
If convicted — by plea or verdict — the court imposes a sentence within the statutory range for the offense classification. Sentencing may include:
- Incarceration (jail or prison depending on the offense level)
- Probation §46-18-201 — Deferred imposition: misdemeanor up to 1 year, felony up to 3 years (2 and 6 years if a financial obligation is imposed); suspended sentence: DOC probation supervision generally capped at 5 years for felonies, but up to 10, 15, or 20 years for specified drug, violent, homicide, and sexual offenses
- Fines and court costs
- Restitution to victims
- Community service
- Mandatory programs (substance abuse, anger management, etc.)
Speedy trial rights
Montana does not set a fixed number of days §46-13-401. Mont. Code Ann. § 46-13-401 requires that after a plea is entered on a misdemeanor charge, the prosecution be dismissed with prejudice, unless good cause to the contrary is shown, if a defendant whose trial has not been postponed on the defendant's own motion is not brought to trial within 6 months. The court may also, on its own motion or on the prosecutor's application in furtherance of justice, dismiss a complaint, information, or indictment; dismissal of a felony charge requires good cause set forth in an order.
