Section 1 of Executive Orders define the underlying behaviors being sanctioned, so let’s skip to the chase and show that for the latest US Executive Order on Libya. People are sanctioned if they are found:
(i) to be responsible for or complicit in, or to have engaged in, directly or indirectly, any of the following:
(A) actions or policies that threaten the peace, security, or stability of Libya, including through the supply of arms or related materiel;
(B) actions or policies that obstruct, undermine, delay, or impede, or pose a significant risk of obstructing, undermining, delaying, or impeding, the adoption of or political transition to a Government of National Accord or a successor government;
(C) actions that may lead to or result in the misappropriation of state assets of Libya; or
(D) threatening or coercing Libyan state financial institutions or the Libyan National Oil Company;
(ii) to be planning, directing, or committing, or to have planned, directed, or committed, attacks against any Libyan state facility or installation (in- cluding oil facilities), against any air, land, or sea port in Libya, or against any foreign mission in Libya;
(iii) to be involved in, or to have been involved in, the targeting of civilians through the commission of acts of violence, abduction, forced displacement, or attacks on schools, hospitals, religious sites, or locations where civilians are seeking refuge, or through conduct that would con- stitute a serious abuse or violation of human rights or a violation of international humanitarian law;
(iv) to be involved in, or to have been involved in, the illicit exploitation of crude oil or any other natural resources in Libya, including the illicit production, refining, brokering, sale, purchase, or export of Libyan oil;
(v) to be a leader of an entity that has, or whose members have, engaged in any activity described in subsections (a)(i), (a)(ii), (a)(iii), or (a)(iv) of this section;
(vi) to have materially assisted, sponsored, or provided financial, material, logistical, or technological support for, or goods or services in support of (A) any of the activities described in subsections (a)(i), (a)(ii), (a)(iii), or (a)(iv) of this section or (B) any person whose property and interests in property are blocked pursuant to this order; or
(vii) to be owned or controlled by, or to have acted or purported to act for or on behalf of, any person whose property and interests in property are blocked pursuant to this order.
The rest is pretty standard – Section 2 bars immigration, Section 3 is about donations, Section 5 is about evasion and avoidance, etc.
