А теперь немного фактов по делу.
Из статьи ABC news:
Trump has called the new immigration policy an executive order, but the text the White House released Wednesday referred to it as a proclamation.
А вот юридические различия между executive order и proclamation :
An executive order is an official, legally binding mandate from the president to federal agencies under the executive branch, advising them on how to interpret and enforce federal law. Under the Constitution, presidents have "executive power" to direct the day-to-day operations of the federal government, and although executive orders aren't specifically addressed in the document, most agree that such orders are legal as long "as the president has authority in the policy area, and those policies are a reasonable interpretation of court precedent."
But some courts have issued temporary or permanent stays on the enforcement of certain executive orders. Executive orders are printed in the Federal Register and consecutively numbered for publication, and are thought to be a way to keep the public informed of policy directives.
Proclamations
Proclamations are largely used for ceremonial purposes and generally don't carry any legal impact.
