Similarly, the Texas Supreme Court has held that the Texas Constitution protects personal privacy from unreasonable intrusion.

T] he Texas Constitution protects personal privacy from unreasonable intrusion. This right to privacy should yield only when the government can demonstrate that an intrusion is reasonably warranted for the achievement of a compelling governmental objective that can be achieved by no less intrusive, more reasonable means

We do not doubt, therefore, that a right of individual privacy is implicit among those `general, great, and essential principles of liberty and free government'established by the Texas Bill of Rights

The Texas Constitution contains several provisions similar to those in the United States Constitution that have been recognized as implicitly creating protected zones of privacy.

This view has been central to our privacy jurisprudence; for example, in describing the Texas Constitution's protection of privacy, this court noted that two provisions in our bill of rights "guarantee the sanctity of the individual's home and person against unreasonable intrusion."

—the Texas Supreme Court ruled that the policy of requiring certain employees to take mandatory polygraph tests impermissible violated the right to privacy found in the Texas Bill of Rights.

Texas State Employees Union was a case decided under the constitutional right to privacy dealing with a mandatory polygraph policy that the mental health department had instituted.

For example, we affirmed an injunction that restrained a state agency from disciplining any employee who refused to take a polygraph test, despite the fact that only a few individuals and the state union raised the constitutional challenge to the polygraph policy

In TSEU, the Texas Department of Mental Health and Mental Retardation had instituted a mandatory polygraph policy requiring employees to submit to a polygraph during the course of an investigation of suspected patient abuse, theft, or other criminal behavior.
