Whenever the United States intends to enter
into evidence or otherwise use or disclose in any
trial, hearing, or other proceeding in or before
any court, department, officer, agency, regu-
latory body, or other authority of the United
States against an aggrieved person any informa-
tion obtained or derived from the use of a pen
register or trap and trace device pursuant to
this subchapter, the United States shall, before

in any trial, hearing, or other proceeding in or
before any court, department, officer, agency,
regulatory body, or other authority of the
United States, or a State or political subdivision
thereof, may move to suppress the evidence ob-
tained or derived from the use of the pen reg-
ister or trap and trace device, as the case may
be, on the grounds that—
(A) the information was unlawfully ac-
quired; or
(B) the use of the pen register or trap and
trace device, as the case may be, was not made
in conformity with an order of authorization
or approval under this subchapter.

cations or orders or other materials relating to

tain, or suppress evidence or information ob-
tained or derived from the use of a pen register

graph (1), the court may disclose to the ag-
grieved person, under appropriate security pro-
cedures and protective orders, portions of the
application, order, or other materials relating to
the use of the pen register or trap and trace de-
vice, as the case may be, or may require the At-
torney General to provide to the aggrieved per-
son a summary of such materials, only where
such disclosure is necessary to make an accu-
rate determination of the legality of the use of
the pen register or trap and trace device, as the
case may be.
(g) Effect of determination of lawfulness
(1) If the United States district court deter-
mines pursuant to subsection (f) that the use of
a pen register or trap and trace device was not
lawfully authorized or conducted, the court
may, in accordance with the requirements of
law, suppress the evidence which was unlawfully
obtained or derived from the use of the pen reg-
ister or trap and trace device, as the case may
be, or otherwise grant the motion of the ag-
grieved person.
(2) If the court determines that the use of the
pen register or trap and trace device, as the case
may be, was lawfully authorized or conducted, it
may deny the motion of the aggrieved person ex-
cept to the extent that due process requires dis-
covery or disclosure.
