Motions to Suppress Evidence in Colorado

A motion to suppress evidence is used to prevent unlawfully obtained evidence from being used against you in court. By keeping out improper evidence, the state may be unable to use that evidence and end up dropping the criminal charges against you. There are a number of reasons your attorney can use to file a motion to suppress evidence in your criminal case.

In this article, our Colorado criminal defense lawyers will address:

Evidence
A motion to suppress evidence is used to prevent unlawfully obtained evidence from being used against you in court.

1. What is a Motion to Suppress Evidence?

A motion to suppress evidence is a legal practice where the defendant makes a request that certain evidence should not be used at trial. The defense attorney makes an argument why the evidence should be excluded, usually based on a violation of the defendant's constitutional rights. If the police obtained evidence in violation of the defendant's Fourth Amendment rights against unlawful search or seizure, then they should not be able to use that evidence in a criminal prosecution.

There are many legal justifications for suppressing evidence in a criminal trial. This includes:

  • Motion to Suppress Breath or Blood Test Results in a DUI
  • Motion to Suppress Evidence for an Invalid Search Warrant
  • Motion to Suppress Evidence for a Warrantless Search
  • Motion to Suppress Evidence for a Warrantless Detention

Searches of the home, person, or property without a warrant may be in violation of the suspect's constitutional rights. Even if the police had a warrant to conduct a search, if there were problems with the warrant or the warrant was invalid, evidence may also be suppressed. However, there are some exceptions to search and seizure rules that allow the police to gather evidence without a warrant.

2. What is the Exclusionary Rule?

Illegally obtained evidence should not be admissible in a criminal trial. This is known as the “exclusionary rule.” Evidence that is obtained in violation of the defendant's constitutional rights is to be excluded.12 However, there are exceptions to the exclusionary rule.

If the police or prosecutor obtained evidence from an independent source, they may be able to use the evidence at trial. Evidence obtained that was only remotely related to an improper source may also be admissible under the attenuation exception. Additionally, evidence obtained by law enforcement who relied on a search warrant they believed was valid may be admissible under the good faith exception.

3. What kind of evidence can be suppressed?

Just about any kind of evidence can be kept out of court through a motion to suppress. As long as there is a legal basis that supports your case, you can file a motion to suppress the evidence. This includes:

  • Physical evidence
  • Photo, audio or video evidence
  • Emails or text messages
  • Blood, breath, or urine samples obtained from the suspect
  • Confessions or other statements

If the police claim to have found drugs in your pocket after an illegal detention, a motion to suppress the drug evidence may leave the police with no case against you. If the police improperly conducted a traffic stop and arrested you for a DUI, you may be able to have your chemical breath test evidence suppressed, leaving them without any physical evidence to continue with the prosecution.

4. What happens during a suppression hearing?

Motions are used in a criminal case to deal with evidentiary issues before your case goes before the jury. The defense attorney will file a motion to suppress evidence, detailing the legal basis for suppressing the evidence. The prosecutor may respond to the motion with their own legal argument is support of admitting the evidence. The judge may then hear arguments during a suppression hearing from each side and question the attorneys about their arguments. The judge will then make a determination as to whether the evidence should be admitted or suppressed.

5. Will my case be dismissed after a suppression hearing?

What happens next after a suppression hearing will all depend on the case. If the judge ruled against your motion to suppress evidence, the prosecutor may be able to use that evidence in a trial. However, your attorney may be able to try and find another legal basis to suppress the evidence, keep it out of trial, or otherwise limit the use of the evidence.

If the judge granted your motion to suppress, the evidence will be barred from use at trial. The prosecutor may then have to rely on any other evidence they have or find other ways to bolster their case against you. They may also appeal the judge's decision, arguing that the judge incorrectly granted the motion in your favor.

If the prosecutor does not have any other evidence that is strong enough to support a case against you, they may drop the charges. If the prosecutor does not want to drop the charges, your attorney may be able to file a motion to dismiss the case. If the judge rules in favor of your motion to dismiss, then your case may be dismissed.
