It’s not surprising that last week’s decision in the Arizona case of Shinn v. Ramirez and Jones didn’t get much coverage outside of the legal media. The decision is procedural rather than substantive, and the majority opinion by Justice Thomas in the 6-3 holding is hard sledding. Nonetheless, it is a classic example of law trumping ethics. The Justice Sotomayor dissent, joined by the other two liberal justices, argues that it trumps law as well.
I would not argue that law must never trump ethics, for law requires consistency and systemic application over the long term to have credibility and integrity. However, Shinn involves a man facing the death penalty, and the decision by the conservative justices chose the virtues of finality over the possibility that the government might be executing an innocent man.
