Models of Judicial Decisionmaking – Posner’s Change of Heart on Voter I.D.

The NY Times Magazine ran a well-written essay by Elizabeth Bazelon about how and when judges change their minds – with prominent mention given of Judge Richard Posner’s public mea culpa regarding his previous approval of a voter I.D. law. The essay isn’t primarily concerned with election law, but with the broader question of how and when judges have intellectual “cover” to change their opinions about something.
