The United States Supreme Court uses it in the context of sovereign immunity.
In Alden v. Maine Justice Souter, for the dissent, wrote that according to natural law a sovereign, like a state, could not be sued in its own court based on a right it created, "A state would be subject to a suit eo nomine in its own courts on a federal claim."
"An eo nomine classification is usually a well-known name or term and includes all items in that class of articles, regardless of form, unless the language of a particular provision limits the scope so as to exclude certain items.
Use does not generally factor into an eo nomine classification though it may be used to establish identity.
"[1] Use of eo nomine is used extensively by the United States Court of International Trade.
