Ellen D. Katz

Ellen D. Katz (born 1968 or 1969) is an American legal scholar at the University of Michigan Law School. Katz has written "a significant body of scholarship on voting rights and election law" and has also written and taught on equal protection, civil rights, and legal history. A scholar of the Voting Rights Act, she wrote a widely cited empirical study of litigation under that act.

Katz has been described as "a liberal law professor and a big fan of the Voting Rights Act of 1965," describing the act as "sacred." However, she has also said that Congress should rework the current VRA, Richard L. Hasen described this as "remarkable" because of Katz's past defenses of the constitutionality of the VRA's section 5.

Katz was a critic of the Supreme Court decision in Northwest Austin Municipal Utility District No. 1 v. Holder in 2009, stating that its narrow statutory, rather than constitutional, ruling was "an improbable one" that "allows just everybody involved in the case to declare victory."

Katz is a critic of the Supreme Court's "congruence and proportionality" test for the congressional power of enforcement of the Fourteenth and Fifteenth amendments, arguing in her 2003 article Reinforcing Representation that the framers of these Reconstruction amendments intended Congress to have broader power.

In Katz's 2009 article Withdrawal: The Roberts Court and the Retreat from Election Law, Katz examined four important election law decisions of the Roberts Court (Lopez Torres, Washington State Grange, Crawford, and Riley) and criticized the Court's "retreat from its longstanding role as the primary guardian of voting rights" as "coming close to embracing empty formalism."

Personal life Katz is married to Daniel Halberstam, who is also a professor at the University of Michigan Law School.
