A Polygraph Examination Can Help Get Criminal Charges Dismissed

Although a polygraph examination is generally not admissible as evidence, it can be a powerful negotiating tool and help get criminal charges dismissed. Clients often worry that nervousness or anxiety might prevent them from passing a polygraph examination; however, a good polygraph examiner can still get reliable results even with a distressing subject. Think about it, wouldn’t anyone taking a polygraph feel at least a little nervous and anxious? A skilled, experienced defense lawyer can help clients determine whether submitting to a private or police polygraph is advisable.

Can I get my charges dismissed if I pass a polygraph examination?

This question became an issue in a recent case handled by LEWIS & DICKSTEIN, P.L.L.C. in Oakland County, Michigan. Our client was charged with armed robbery. No one disputed that the robbery occurred, but we contested the identification of our client. Our client was adamant that he was innocent and did not commit the crime. Soon after the robbery, the police found our client and another man together in Oakland County, Michigan. They allegedly matched the “description” of the alleged perpetrators. The witnesses identified our client and the other man as the two people who committed the robbery. This process is commonly referred to as a “show up.” Our client maintained that he had just met up with the other man and was unaware that he might have committed the robbery.

When we met with our client, he informed me that several people could vouch for his alibi and that he was home at the time of the crime. The firm’s investigator and attorneys interviewed the witnesses and believed the alibi witnesses were truthful. For the next several weeks, the investigators and our lawyers worked tirelessly to develop a compelling argument to present to the prosecutor to get the case dismissed. As just one tool in the process, the client agreed to take a private polygraph to help get their criminal charges dismissed. It was no surprise that he passed with flying colors. The prosecutor learned that LEWIS & DICKSTEIN, P.L.L.C. utilizes one of Michigan’s most credible polygraph examiners. Because of our polygraph examiner’s impeccable and honest reputation, the prosecutor did not even request a police polygraph.

Frequently Asked Questions


Is a polygraph enough to convict?

Can a polygraph prove your innocence?

Yes and no. A polygraph can be used to prove your innocence to a detective, prosecutor, employer, etc.; however, it cannot prove your innocence at trial because it is not admissible.

How could polygraph results be used in plea bargaining?
