Somalia

The Somalia sanctions program represents the implementation of multiple legal authorities. Some of these authorities are in the form of executive orders issued by the President. Other authorities are public laws (statutes) passed by The Congress. These authorities are further codified by OFAC in its regulations which are published the Code of Federal Regulations (CFR). Modifications to these regulations are posted in the Federal Register. In addition to all of these authorities, OFAC may also implement United Nations Security Council Resolutions (UNSCRs) with regard to the Somalia.
