alt Hacker NewsBit weird to make a fuss about the constitution just to say the law is the law, you make it sound like breaking the ordinary law is unconstitutional.
But yes, everyone has an obligation to follow the law, which is what exactly this EO is about. Federal agencies don't get to pick and choose their own creative interpretations of the law, they have to follow the actual law. The president literally has a constitutional duty to take care that the laws are faithfully executed, and this EO is him doing that.
The EO contradicts the Constitution by declaring that agencies must refer to the President and the Attorney General for all interpretations of the law. This is a novel proposal not rooted in the historical functioning of the federal government.
The government agencies' powers come from the legislature and must follow U.S. Code, derived from the legislature's laws. Agencies hire their own counsel to make guidelines and regulations from U.S. Code.
As a technologist, you have the confidence to interpret the law and the Constitution from your version of reasoning from first principles. However, the Supreme Court and other courts repeatedly disagree with your interpretation, which willfully ignores the first article in favor of the second.
