From the NYT:
A few times a year, Supreme Court justices go out of their way to emphasize their unhappiness by reading a dissent from the bench out loud, supplementing the dry reason on the page with vivid tones of sarcasm, regret, anger and disdain. The practice is on the rise, and it is suggestive of an increasingly polarized court.
“Dissenting from the bench,” a new study to be published in Justice System Journal contends, is a sort of nuclear option that “may indicate that bargaining and accommodation have broken down irreparably.”
