The actual law says that the domain registrar has to be issued a court order to shut down a domain:
See section 2324, subsection e
e) Service of Court Order-
(1) DOMESTIC DOMAINS- In an in rem action to which subsection (d)(1) applies, the Attorney General shall serve any court order issued pursuant to this section on the domain name registrar or, if the domain name registrar is not located within the United States, upon the registry. Upon receipt of such order, the domain name registrar or domain name registry shall suspend operation of, and lock, the domain name.
