“Nationwide” Injunctions, Birthright Citizenship, and the Supreme Court Decision in Trump v. CASA

The case is here. For a variety of takes from the commentators, see, e.g.,

What is a “Nationwide Injunction”?

The term “nationwide injunction” is inapt and misleading, but lots of people want to use it anyway. So let’s define it for present purposes. For present purposes, a “nationwide injunction” is an injunction issued in a case brought by one or more persons (either two-legged persons or juridical persons such as corporations) that protects not only the individual plaintiff(s) but also everyone else in a similar legal position, even though there is no certified “class action” in accordance with Rule 23 of the Federal Rules of Civil Procedure

As so defined, a nationwide injunction is an end run around the normal requirements for class certification under Rule 23.[1]

To illustrate and explain the point: Plaintiffs in the CASA case include four new mothers and their babies, one pregnant woman and her unborn child, and three undocumented immigrant women who might become pregnant. If the plaintiffs wanted to secure a ruling protecting not only their children but also all children whom Trump threatened to deprive of citizenship, then the normal/traditional route would be to ask the district court to “certify” such a “class” of similarly situated mothers. That class certification process involves a number of inquiries about whether it would be advisable for the litigation to go forward on a class basis, not an individual basis. But Liza, Andrea, and the other expectant mothers asked for nationwide/universal relief, without going through the certification exercise.

Before Trump v. CASA, Was There a Legitimate Legal Controversy about Whether Courts Could Issue “Nationwide Injunctions”?

Yes. Long story. But yes. 

In fact, the Biden administration asked the Supreme Court to impose severe limitations on “nationwide injunctions.”

Some Say it was Odd—and Inadvisable—for the Court to Rule on the “Nationwide Injunction” Question but Kick the Can Down the Road on the Substantive Issue of Birthright Citizenship. Do You Agree?

Yes, I do agree. And if anyone reading this post wants to delve deeper, many of the sources cited above will be useful.

But I think the much more interesting question is whether plaintiff can represent a class of similarly situated mothers, babies, and unborn children.

And whether, by so complying with Rule 23, they can find effective legal relief against Trump’s illegal position on birthright citizenship.

What’s Going to Happen Next in the Birthright Citizenship Cases?

I’ll write about that in my next post, which will appear immediately above this one, because the posts on my blog appear in reverse chronological order.


[1] Related, but distinct, issues are raised by lawsuits with plaintiffs claiming to represent a category of other people—for example, a suit brought by a state government on behalf of all its citizen or a suit brought by a trade association on behalf of all its members. Team Trump challenged the “standing” of states and associations to bring such cases, but the Court decided to kick this can down the road.
