Threats to judicial independence are most commonly viewed as arising either from politically motivated depredations by other branches of government, or from improper inducements or coercion from individuals or groups in the wider society. Both types of threats are external to the court. What of the internal environment within which judges operate, particularly the immediate environment comprised of their colleagues on the bench? Drawing on a judicial career spanning thirty-seven years, including fifteen as a U.S. District Court judge and the past seven in my present position on the U.S. Court of Appeals for the Sixth Circuit, as well as on legal scholarship and the perspectives of other jurists past and present, I will address what one scholar calls the “complicated interdependent decisions” faced by judges on multi-member courts. This Lecture will explore the often complex calculus and subtle intrajudicial considerations that go into a judge’s decision whether—and, if so, how—to dissent in a particular case. I encourage reflection both on the costs that dissent exacts on the individual judge and on the court as a whole, and on the enormous value it can have as an expression of legal conscience and even, on occasion, as a voice of prophecy pointing to future change in the law. Ultimately, I view the right to dissent as precious, and a pillar of judicial independence.
