Section 40-6-302 - Legislative purpose(a) In order to protect the privacy of wire, oral, and electronic communications, to protect the integrity of court and administrative proceedings, to define, on a uniform basis, the circumstances under which a district attorney general may apply to a court of competent jurisdiction for the interception and use of wire, oral, and electronic communications, to define the circumstances under which a judge in a court of competent jurisdiction may authorize the interception and use of wire, oral and electronic communications, and to prohibit any unauthorized interception or use of those communications, it is necessary for the general assembly to define the circumstances and conditions under which the interception of wire, oral and electronic communications may be lawful. In defining these circumstances, the general assembly seeks to strike a balance between an individual's right to privacy and society's legitimate concern in being protected from criminal activity.(b) In carrying out illegal activities, criminals often make extensive use of wire, oral and electronic communications. The lawful interception of these communications is an indispensable aid to investigative and law enforcement officials in obtaining evidence of illegal activities. Likewise, it is necessary for the general assembly to safeguard the privacy of innocent persons. Through this part and §§ 39-13-601 - [former] 39-13-603 [repealed], the general assembly seeks to prohibit the unauthorized interception of wire, oral and electronic communications and to prohibit the use of illegally obtained wire, oral and electronic communications as evidence in courts and administrative proceedings. The interception of wire, oral or electronic communications, therefore, when no party to the communications has consented to the interception, should be allowed only under compelling circumstances when authorized and supervised by a court of competent jurisdiction and upon a finding of probable cause. Court authorization and supervision ensures that the interception is made only in narrowly defined circumstances and that the information obtained will not be misused. The privacy rights of Tennessee citizens are further protected by limiting the interception of wire, oral, and electronic communications to certain major types of felonies under this code.
