31 CFR § 595.311 - Specially designated terrorist.
(a) The term specially designated terrorist means:
(2) Foreign persons designated by the Secretary of State, in coordination with the Secretary of the Treasury and the Attorney General, because they are found:
(i) To have committed, or to pose a significant risk of committing, acts of violence that have the purpose or effect of disrupting the Middle East peace process, or
(ii) To assist in, sponsor, or provide financial, material, or technological support for, or services in support of, such acts of violence; and
(3) Persons determined by the Secretary of the Treasury, in coordination with the Secretary of State and the Attorney General, to be owned or controlled by, or to act for or on behalf of, any other specially designated terrorist.
The names of persons determined to fall within this definition, whose property and interests in property therefore are blocked pursuant to this part, are published in the Federal Register and incorporated into the Office of Foreign Assets Control's Specially Designated Nationals and Blocked Persons List (“SDN List”) with the identifier “[SDT].” The SDN List is accessible through the following page on the Office of Foreign Assets Control's Web site: http://www.treasury.gov/sdn. Additional information pertaining to the SDN List can be found in appendix A to this chapter. See § 595.410 concerning entities that may not be listed on the SDN List but whose property and interests in property are nevertheless blocked pursuant to this part.
The International Emergency Economic Powers Act (50 U.S.C. 1701-1706), in Section 203 (50 U.S.C. 1702), authorizes the blocking of property and interests in property of a person during the pendency of an investigation. The names of persons whose property and interests in property are blocked pending investigation pursuant to this part also are published in the Federal Register and incorporated into the SDN List with the identifier “[BPI-SDT].”
Section 501.807 of this chapter sets forth the procedures to be followed by persons seeking administrative reconsideration of their designation, or who wish to assert that the circumstances resulting in the designation are no longer applicable.
