Texas Penal Code Practice

In Texas law, "false imprisonment" is defined as the unlawful confinement or restraint of a person against their will. The key aspect that makes option C the correct answer is that it emphasizes the absence of legal authority in restricting a person's movement. This means that if a person is held or restrained without their consent and without the legal justification to do so, it constitutes false imprisonment.

The other choices do not align with the legal definition of false imprisonment. For instance, restricting another person's movement legally signifies that there is appropriate permission or authority (as in the case of law enforcement under certain circumstances), which does not constitute false imprisonment. Similarly, voluntary consent to movement restrictions or detaining a person with their consent implies that the individual agrees to the limitations being placed on their freedom, which also removes the element of unlawful restraint necessary for a claim of false imprisonment.
