What Court case that established the Employee Polygraph Protection Act?

The Employee Polygraph Protection Act (EPPA) was established following concerns about the use of polygraph tests in the workplace, but it was not directly tied to a specific court case. Instead, it was enacted by Congress in 1988 and aimed to protect employees from discrimination based on polygraph test results. The law prohibits most employers from using lie detector tests for pre-employment screening or during employment, thereby setting clear limitations on the use of such testing in the workplace.
