Is a Polygraph Admissible in Court in Colorado? Updated Guidance from Crosspoint Solutions LLC

At Crosspoint Solutions LLC, we get this question constantly: “Can my polygraph or EyeDetect test be used in court?”

Here’s the straightforward answer:

No—polygraph and EyeDetect results are not admissible in the jury trial portion of a criminal case in Colorado.

Colorado courts do not allow these results to be presented to a jury as evidence of guilt or innocence.

But that’s only part of the story.

Where Polygraph and EyeDetect Are Useful in Colorado Cases

While you can’t introduce the results during a jury trial, these tools are widely used—and often extremely valuable—during pretrial and post‑trial proceedings. In fact, we conduct a large number of polygraph and EyeDetect tests for exactly these purposes.

Attorneys, investigators, and defendants use credibility testing to help with:

• Witness dismissal or verification

• Clarifying “he said, she said” situations

• Plea negotiations

• Evidence disputes

• Post‑conviction hearings

• Internal investigations

• Pre‑employment or administrative reviews

  
  

In these contexts, the results can influence decisions, shape strategy, and help attorneys determine the most effective path forward.

Why Polygraphs Are a “Pandora’s Box”

We often tell clients that taking a polygraph is like opening Pandora’s box—once it’s open, you can’t put everything back inside.

Think about your own reaction when you hear someone “passed a polygraph. ”Do you still feel a little doubt? Probably.

Now think about when you hear someone “failed a polygraph. ”Does your mind jump straight to guilt? For most people, it does.

Judges, prosecutors, and defense attorneys are human too. They have the same instinctive reactions. That’s why these tests are powerful tools—but also why they must be used strategically.

So Should You Take a Polygraph?

Here’s our honest take: If you’re telling the truth, you shouldn’t be afraid of the process.

Polygraph and EyeDetect testing can:

• Strengthen your credibility

• Support your attorney’s negotiations

• Help resolve disputes early

• Provide clarity in complex cases

At Crosspoint Solutions LLC, we’ve seen these tools make a meaningful difference in countless situations.

Final Thoughts

Polygraph and EyeDetect results may not be admissible in front of a jury in Colorado, but they remain powerful tools in the legal process. Used correctly, they can influence decisions long before a case ever reaches trial—or long after a verdict has been delivered.
