There seems to be a public perception that the members of the current, often divided, Supreme Court vote for partisan rather than principled reasons. As recent confirmation hearings have become more heated and polarized, this belief has only crystallized. In Active Liberty: Interpreting Our Democratic Constitution, Justice Stephen Breyer challenges this perception through a thoughtful discussion of the constitutional commitments that inform his decisions. This book does not provide a comprehensive theory of constitutional and statutory interpretation; rather, Active Liberty is important because in it, Justice Breyer gives the American public insight into the constitutional themes and values that he draws on when deciding cases. In particular, Justice Breyer focuses on one constitutional value that he believes has been underappreciated: a commitment to democratic participation and self-government which he calls “active liberty.” Although Justice Breyer recognizes that other constitutional values are important, he believes that active liberty should play a more prominent role in constitutional adjudication.
