Analysis by the Legislative Reference Bureau
This bill expands the definition of “pen register” and “trap and trace device.”
Under current law, a “pen register” is defined as a device that records or decodes
electronic or other impulses that identify the numbers dialed or transmitted on a
telephone line. Current law defines a “trap and trace device” as a device that
captures the incoming electronic or other impulses that identify the originating
number of an instrument or device from which a wire or electronic communication
was transmitted. Current law provides that the attorney general or a district
attorney may apply for a court order to install a pen register or a trap and trace device
for the purpose of furthering a criminal investigation.
This bill expands the definition of “pen register” to include a device or process
that records or decodes dialing, routing, addressing, or signaling information
transmitted on a telephone line or by an instrument or facility from which a wire or
electronic communication is transmitted. This bill expands the definition of “trap
and trace device” to include a device or process that identifies the originating number
or other dialing, routing, addressing, and signaling information of an instrument or
facility from which a wire or electronic communication was transmitted.
The bill also allows the attorney general or a district attorney to apply for an
order for a pen register or trap and trace device in the circuit court of any county.

Under current law, an application for a pen register or trap and trace device must
be filed in the circuit court in the county where the device is to be located.
Under the bill, a person is considered to be doing business in this state, for the
purposes of a pen register or trap and trace device order, if the person contracts with
or engages in a terms of service agreement with any other person for the use of a line,
instrument, or facility, and any part of the performance of the contract or provision
of service takes place within this state on any occasion.
