In the courts below:
A federal judge in North Carolina and the Fourth US Circuit Court of Appeals in Richmond have ruled that Section 4248 violates principles of federalism and the structure of government as laid down in the Constitution.
“The power claimed by Section 4248 – forcible, indefinite civil commitment – is among the most severe wielded by any government,” the Fourth Circuit declared in a January 2009 decision. “The Framers, distrustful of such authority, reposed such broad powers in the states, limiting the national government to specific and enumerated powers.”
The Government is arguing:
Solicitor General Elena Kagan says Congress may pass laws related to the federal criminal justice and penal system. She says Section 4248 is a “necessary and proper” use of federal power to protect the public.
60 inmates are being held in North Carolina under the law. An example:
Mr. Comstock was sentenced to three years in federal prison after pleading guilty to possessing child pornography. Six days before his scheduled release from prison, federal authorities moved to have him certified as a “sexually dangerous person.” To date, Comstock has spent six years in federal custody.

Update: A Scalia snippet:
JUSTICE SCALIA: General Kagan, you are relying on the Necessary and Proper Clause, right? You say: But necessary and proper doesn't mean it is necessary and proper for the good of society. It means it is necessary and proper for the execution of another power that the Federal Government is given by the Constitution. Now why is this necessary for the execution of any Federal power? The Federal criminal proceeding has terminated. The individual is released. You could say it's necessary for the good of society, but that's not what the Federal Government is charged with. Why is it necessary to any function that the Federal Government is performing? It has completed its performance of the function of incarcerating this individual until he's served his punishment.
