"Certain persons"? Here's much of the text of the order, with my emphases in bold:
I, GEORGE W. BUSH, President of the United States of America, find that, due to the unusual and extraordinary threat to the national security and foreign policy of the United States posed by acts of violence threatening the peace and stability of Iraq and undermining efforts to promote economic reconstruction and political reform in Iraq and to provide humanitarian assistance to the Iraqi people, it is in the interests of the United States to take additional steps with respect to the national emergency declared in Executive Order 13303 of May 22, 2003, and expanded in Executive Order 13315 of August 28, 2003, and relied upon for additional steps taken in Executive Order 13350 of July 29, 2004, and Executive Order 13364 of November 29, 2004. I hereby order:
Section 1. (a) Except to the extent provided in section 203(b)(1), (3), and (4) of IEEPA (50 U.S.C. 1702(b)(1), (3), and (4)), or in regulations, orders, directives, or licenses that may be issued pursuant to this order, and notwithstanding any contract entered into or any license or permit granted prior to the date of this order, all property and interests in property of the following persons, that are in the United States, that hereafter come within the United States, or that are or hereafter come within the possession or control of United States persons, are blocked and may not be transferred, paid, exported, withdrawn, or otherwise dealt in: any person determined by the Secretary of the Treasury, in consultation with the Secretary of State and the Secretary of Defense,
(i) to have committed, or to pose a significant risk of committing, an act or acts of violence that have the purpose or effect of:
(A) threatening the peace or stability of Iraq or the Government of Iraq; or
(B) undermining efforts to promote economic reconstruction and political reform in Iraq or to provide humanitarian assistance to the Iraqi people;
(ii) to have materially assisted, sponsored, or provided financial, material, logistical, or technical support for, or goods or services in support of, such an act or acts of violence or any person whose property and interests in property are blocked pursuant to this order; or
(iii) to be owned or controlled by, or to have acted or purported to act for or on behalf of, directly or indirectly, any person whose property and interests in property are blocked pursuant to this order.
(b) The prohibitions in subsection (a) of this section include, but are not limited to, (i) the making of any contribution or provision of funds, goods, or services by, to, or for the benefit of any person whose property and interests in property are blocked pursuant to this order, and (ii) the receipt of any contribution or provision of funds, goods, or services from any such person.
Sec. 2. (a) Any transaction by a United States person or within the United States that evades or avoids, has the purpose of evading or avoiding, or attempts to violate any of the prohibitions set forth in this order is prohibited.
(b) Any conspiracy formed to violate any of the prohibitions set forth in this order is prohibited.
Sec. 3. For purposes of this order:
(a) the term "person" means an individual or entity;
(b) the term "entity" means a partnership, association, trust, joint venture, corporation, group, subgroup, or other organization; and
(c) the term "United States person" means any United States citizen, permanent resident alien, entity organized under the laws of the United States or any jurisdiction within the United States (including foreign branches), or any person in the United States.
Sec. 4. I hereby determine that the making of donations of the type specified in section 203(b)(2) of IEEPA (50 U.S.C. 1702(b)(2)) by, to, or for the benefit of, any person whose property and interests in property are blocked pursuant to this order would seriously impair my ability to deal with the national emergency declared in Executive Order 13303 and expanded in Executive Order 13315, and I hereby prohibit such donations as provided by section 1 of this order.
Sec. 5. For those persons whose property and interests in property are blocked pursuant to this order who might have a constitutional presence in the United States, I find that, because of the ability to transfer funds or other assets instantaneously, prior notice to such persons of measures to be taken pursuant to this order would render these measures ineffectual. I therefore determine that for these measures to be effective in addressing the national emergency declared in Executive Order 13303 and expanded in Executive Order 13315, there need be no prior notice of a listing or determination made pursuant to section 1(a) of this order....
Okay, let me get this right. Anyone suspected of an act of violence or supports anyone who is suspected of an act of violence or conspiracy to make an act of violence, all of which is vaguely intended to impede what the Administration thinks is "progress", will have their property seized without notice.
I think this is called illegal seizure. Will this stand? I'm no attorney, but this all sounds very scary.
By comparison, here's the text of the Fifth Amendment to the U.S. Constitution:
No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.
Is the Constitution now, too, nothing but shreds of ancient paper?
