Has any court ruled on the constitionality of a pre-employment polygraph, where the arm of government relies upon the results of a polygraph exam to make an employment decision?
In looking at the poly litigation link on the website, I couldn't see any, and I have done some limited legal research, but haven't covered all 50 states, and the federal circuits.
The legal argument would be that relying upon a test which is not verifyably accurate would be arbitrary and capricious, and violate an applicants 14th amendments rights to due process.
Please respond, of anyone knows of any precedent having been set in any court.
