Anonymous Law Review Articles?

I'm reading Isaac and Armat's Madness in the Streets, about mental illness deinstitutionalization. They refer to a Yale Law Journal article described as written by an anonymous state legislator. I found this a bit bizarre--but sure enough, there are a number of references to it, and none of them list an author's name. "Mental Illness: A Suspect Classification?" Yale Law Journal, Vol. 83, 1974, pp. 1237-70.

Isn't this a little bizarre? Have you ever seen a law review article published without the author's name?
