Can criminal charges be dismissed before trial in Colorado?

On Behalf of | Oct 22, 2026 | Criminal Defense |

Facing criminal charges can be a harrowing experience, especially if it seems a trial is inevitable. You may understandably start getting anxious over how a potential conviction may affect your freedom, reputation and future. But a charge does not always guarantee that your case will make it to court.

Here are some situations that may lead to dismissal of your case before trial.

Insufficient evidence may justify dismissal

If the prosecution fails to establish the legal grounds needed to proceed with your case, the judge may decide to dismiss your case. For example, if there is not enough evidence to prove a major part of the alleged crime, your defense attorney can challenge whether the trial should proceed.

However, weak evidence alone does not automatically lead to dismissal. There must be enough to cast significant doubt on whether you committed the supposed crime.

Illegal evidence may weaken the prosecution’s case

Even if police suspect you of a crime, you still have rights under the U.S. Constitution and Colorado law. For example, police generally need a warrant to search your home unless a legal exception applies. If officers conduct an unlawful search and seize your property, your attorney may ask the judge to suppress that evidence under Colorado Rule of Criminal Procedure 41.

However, not every mistake by law enforcement results in excluded evidence. Under Colorado Revised Statutes § 16-3-308, a court generally cannot suppress otherwise admissible evidence seized because of certain good-faith mistakes or technical violations.

If the judge excludes evidence and the prosecution no longer has enough to support the charges, the court may dismiss your case.

Procedural violations may affect whether a case proceeds

Certain legal errors may justify dismissal, including violations of your right to a speedy trial. In Colorado, prosecutors generally must bring you to trial within six months after you enter a not-guilty plea, although specific exceptions and delays can change the deadline. Your attorney can review the case timeline to determine whether the court should dismiss the charges.

A dismissal may not end the case

A dismissal does not automatically mean you have been acquitted or that prosecutors can never charge you again. An acquittal means the court or jury finds you not guilty, while the effect of a dismissal depends on the court’s ruling.

Prosecutors may sometimes refile charges after a dismissal without prejudice, including when they obtain additional evidence. However, legal limits, including double jeopardy protections, may prevent another prosecution.

Protect your rights even when facing criminal charges

A dismissal depends on the facts, evidence and legal issues in your case. An attorney can review the prosecution’s evidence, examine how police gathered it and assess whether any violations support a request for dismissal. Getting legal advice early can also help you understand which challenges apply to your situation and what steps to take next regarding your case.
