Polygraph results as evidence

11 posts in this topic

Hello, this is in the state of California. Pursuant to Cal. Evd. Code, sections copied below, I am curious on if polygraph results would be allowed as evidence in a civil case by the plaintiff who wants to substantiate her allegations as set forth in the case?

351. Except as otherwise provided by statute, all relevant evidence

is admissible.

351.1. (a) Notwithstanding any other provision of law, the results

of a polygraph examination, the opinion of a polygraph examiner, or

any reference to an offer to take, failure to take, or taking of a

polygraph examination, shall not be admitted into evidence in any

criminal proceeding, including pretrial and post conviction motions

and hearings, or in any trial or hearing of a juvenile for a criminal

offense, whether heard in juvenile or adult court, unless all

parties stipulate to the admission of such results.

(B) Nothing in this section is intended to exclude from evidence

statements made during a polygraph examination which are otherwise

admissible.

As its plain wording indicates, EC 351.1 has no application in civil cases. EC 351 is nothing but the basic law on relevance and has no direct bearing on polygraph results. Therefore, if your question was limited to asking whether these two statutes would allow admission of polygraph results, the answer is no.

The answers to the questions given during the polygraph, however, may be admissible.

I edited "LegalwriterOne's" statement above to make it more accurate. The answers might be admissible depending on who was being examined, what the questions where, who is seeking to offer the answers, and for what purpose that person is offering them. In other words, without a lot more information, we can't tell you much of anything useful regarding the admissibility of polygraph questions and answers. As far as the admissibility of polygraph results in a civil case, I suggest a visit to a law library and a review of Witkin's California Evidence treatise.

The blog was helpful, I'm going to print it up and bring it to the judge when I ask about introducing polygraph results. Thanks much! I just want to prove that I am not the liar in this case. My opponent is a good one. I wish he would take one! LOL

Don't bother. It's not a legal treatise and it's not legal authority.

"I wish he would take one! LOL"

So ... I'm confused. If he hasn't taken one, what's the point of your question? (I'd hope you aren't actually thinking of asking the court to order him to submit to one, 'cause that won't happen.)

No. What I wanted to do was take one myself, and have the examiner ask me if everything in my complaint is true (and that's a yes), and then if the defendant has told lies in his declaration, answer, etc. (that is also a yes).

I was hoping something above and beyond to corraborate my story would assist to verify I have been honest; thus help me win.

First of all, are "kraut32" and "luckygerm" different screen names being used by the same person?

Even if this article were mandatory legal authority, you don't simply print out authorities and show them to the judge in court (at least not in most circumstances). You haven't described the context in which you want to do this, so I would simply say that you should be careful with this. More importantly, while the article to which the moderator provided a link was written by a California lawyer, it is not specific to California law and cites not actual legal authority. Indeed, it focuses on the U.S. Supreme Court's decision in a case called Daubert, which itself has nothing to do with polygraphs (except to the extent that it contains a discussion of an old federal appellate case called Frye, which involved "a crude precursor to the polygraph machine"). Daubert set the standard in federal courts regarding the use of scientific evidence. Daubert is not binding authority in California; California has its own standards under the California Evidence Code (which is different than the Federal Rules of Evidence). If you were to show the article to a judge, his/her response likely would be to say, "ok, show me a California case that would allow me to consider the results of a polygraph test."

What I wanted to do was take one myself, and have the examiner ask me if everything in my complaint is true (and that's a yes), and then if the defendant has told lies in his declaration, answer, etc. (that is also a yes).

You cannot do that. If you have real evidence that corroborates your testimony, by all means use it. If you have evidence that controverts what you believe will be the other party's story, use it. If you have evidence that may impeach the other party's credibility, use it. But you can't manufacture artificial evidence to bolster your own credibility.

I'm afraid a polygraph demonstrating your belief (or certainty) that the other guy is lying won't be admissible. You need to demonstrate by other means that he's lying (or at least that it is more likely than not that he's lying).

Okay, I'm just so squeaky honest that I thought it might help. Everything else is looking good, though. You know when someone is being deceitful, it gets harder and harder for them to cover it up as time goes on... that's what is happening now. Thank you.
