### §1805. Issuance of order

#### (a) Necessary findings

Upon an application made pursuant to section 1804 of this title, the judge shall enter an ex parte order as requested or as modified approving the electronic surveillance if he finds that—

(1) the application has been made by a Federal officer and approved by the Attorney General;

(2) on the basis of the facts submitted by the applicant there is probable cause to believe that—

(A) the target of the electronic surveillance is a foreign power or an agent of a foreign power: Provided, That no United States person may be considered a foreign power or an agent of a foreign power solely upon the basis of activities protected by the first amendment to the Constitution of the United States; and

(B) each of the facilities or places at which the electronic surveillance is directed is being used, or is about to be used, by a foreign power or an agent of a foreign power;

(3) the proposed minimization procedures meet the definition of minimization procedures under section 1801(h) of this title; and

(4) the application which has been filed contains all statements and certifications required by section 1804 of this title and, if the target is a United States person, the certification or certifications are not clearly erroneous on the basis of the statement made under section 1804(a)(7)(E) 1 of this title and any other information furnished under section 1804(d) 1 of this title.

#### (b) Determination of probable cause

In determining whether or not probable cause exists for purposes of an order under subsection (a)(2), a judge may consider past activities of the target, as well as facts and circumstances relating to current or future activities of the target.

#### (c) Specifications and directions of orders

(1) Specifications.—

An order approving an electronic surveillance under this section in circumstances where the nature and location of each of the facilities or places at which the surveillance will be directed is unknown shall direct the applicant to provide notice to the court within ten days after the date on which surveillance begins to be directed at any new facility or place, unless the court finds good cause to justify a longer period of up to 60 days, of—

(A) the nature and location of each new facility or place at which the electronic surveillance is directed;

(B) the facts and circumstances relied upon by the applicant to justify the applicant's belief that each new facility or place at which the electronic surveillance is directed is or was being used, or is about to be used, by the target of the surveillance;

(5) 3 An extension of an order issued under this subchapter for surveillance targeted against a United States person, to the extent practicable and absent exigent circumstances, shall be granted or denied by the same judge who issued the original order unless the term of such judge has expired or such judge is otherwise no longer serving on the court.

#### (e) Emergency orders

(1) Notwithstanding any other provision of this subchapter, the Attorney General may authorize the emergency employment of electronic surveillance if the Attorney General—

This chapter, referred to in subsecs. (d), (f)(1), and (i), was in the original "this Act", meaning Pub. L. 95–511, Oct. 25, 1978, 92 Stat. 1783, which is classified principally to this chapter.

#### Codification

As originally enacted, Pub. L. 107–56, §225, amended this section by adding subsec. (h) relating to bar of legal action after subsec. (g). The section already contained a subsec. (h). Both Pub. L. 107–108, §314(a)(2)(C), and Pub. L. 107–273, §4005(c), made amendments retroactive to the date of enactment of Pub. L. 107–56 which had the effect of redesignating subsec. (h), relating to bar of legal action, as subsec. (i) and transferring it to appear at the end of this section. See 2001 Amendment notes, Effective Date of 2002 Amendment note, and Effective Date of 2001 Amendment note below.

#### Amendments

2024—Subsec. (d)(1)(A). Pub. L. 118–49, §6(g)(1)(A)(i), which directed the substitution of "against a foreign power" for "against a foreign power, as defined in section 1801(a), (1), (2), or (3) of this title," was executed by making the substitution for "against a foreign power, as defined in section 1801(a)(1), (2), or (3) of this title," to refelct the probable intent of Congress.

Subsec. (d)(1)(B). Pub. L. 118–49, §6(g)(1)(A)(ii), substituted "one year" for "120 days".

Subsec. (d)(2) to (4). Pub. L. 118–49, §6(g)(1)(B), (C), redesignated pars. (3) and (4) as (2) and (3), respectively, and struck out former par.

L. 114–23, which delayed the reversion of subsec. (c)(2) from June 1, 2015, to Dec. 15, 2019, was given effect to reflect the probable intent of Congress, notwithstanding that Pub.

1984—Subsec. (f)(2)(C). Pub. L. 98–549 substituted "section 705" for "section 605" in the original to accommodate renumbering of sections in subchapter VI (section 601 et seq.) of chapter 5 of Title 47, Telegraphs, Telephones, and Radiotelegraphs, by section 6(a) of Pub. L. 98–549. Because both sections translate as "section 605 of Title 47", the amendment by Pub. L. 98–549 resulted in no change in text.
