Over at Balkinization Stephen Griffin
beat me to the task of (favorably) noting a recently-released book by Stefanie Lindquist
and Frank Cross (both at Texas),
Measuring Judicial Activism. Published by Oxford, info on the book is here. As Stephen notes, "When they (Lindquist and Cross)
cumulate the scores of judicial activism across all dimensions, the top
activist justices turn out to be Douglas, Black, and Warren, with Brennan and Marshall close behind. Justices Burger and Frankfurter rank last. The book is
consistently interesting and well worth reading."
