The Federal Judicial Center, which is part of the Federal Court System and chaired by the Chief Justice, has a multitude of resources to review, including the court's review of executive orders:

Courts reviewing executive orders and executive actions is literally nothing new. Courts issuing injunctive relief on executive orders and admnistrative actions is similarly not a new thing. It is laughable to say otherwise.
Since 2001, there have been 96 district court nation wide injunctions:
Bush: 6
Obama: 12
Trump 64
Biden 14
I would also point that when the northern district of Texas issued a nationwide injunction in the mifepristone case, the Republicans rejoiced in the "rule of law". That injunction was ultimately stayed by the 5th Circuit, but the hand wringing over a national injunction when it doesn't suit your desires while jumping for joy over a national injunction by district judge over something like mifepristone because it fits your agenda is troubling.
The Alien Enemies Act is a problematic one. It is rife for abuse and that is exactly what Jefferson and Madison pointed out. The actual language is below:
"Whenever there is a
declared war between the United States and
any foreign nation or government,
or any invasion or predatory incursion is perpetrated, attempted, or threatened against the territory of the United States
by any foreign nation or government, and the President makes public proclamation of the event, all natives, citizens, denizens, or subjects of the hostile nation or government, being of the age of fourteen years and upward, who shall be within the United States and not actually naturalized, shall be liable to be apprehended, restrained, secured, and removed as alien enemies. The President is authorized in any such event, by his proclamation thereof, or other public act, to direct the conduct to be observed on the part of the United States, toward the aliens who become so liable; the manner and degree of the restraint to which they shall be subject and in what cases, and upon what security their residence shall be permitted, and to provide for the removal of those who, not being permitted to reside within the United States, refuse or neglect to depart therefrom; and to establish any other regulations which are found necessary in the premises and for the public safety." (emphasis added)
The only time this Act has ever been used was during actual war time. The war time that is declared by Congress--so now we just have to look at the second part of the Act "or any invasion or predatory incursion perpetrated, attempted or threatened against the territory of the United States by any foreign nation or goverment." This part of the Act has never been invoked other than in an official state of war, which is clear by the mandate that the threat/incursion must come by a foreign nation or government. The discussion about this section in the draft centered around attacks by recognized governments/nations in times not in war. Strict reading supported by the legislative intent.
The Act itself has been added to with specific protections over the years such as providing deportees a reasonable time period to get their affairs together.
It is too bad people never bother to read the briefings or the full opinion. Taking snippets and posting it on twitter or message boards just amplifies the misunderstandings.
