(1) A public safety answering point (PSAP) may make a reverse search of information in the automatic location identification (ALI/DMS) database when, in the judgment of the PSAP representative, an immediate response to the location of the caller or to the location of another telephone number reported by the caller is necessary because of an apparent emergency.

(2) Absent a judicial order, reverse search must not be used for criminal or legal investigations or other nonemergency purposes.
