Law professor and dean Erwin Chemerinsky has written this op-ed about the tone of Justice Scalia's opinions.
Here's the beginning:
Justice Antonin Scalia is setting a terrible example for young lawyers. Ignore, for now, his jurisprudence, his famously strict originalism; it's his tone that's the problem.
I have taught argumentation for many years, first as an instructor to high school and college debaters, currently as a law professor. Throughout my career I have always cautioned students away from nastiness as a crutch for those who cannot win using reason or legal precedent. I have told them to stick to persuasion and to dissecting the opposition's logical fallacies.
But lately my students have been turning in legal briefs laced with derision and ad hominem barbs. For this trend, I largely blame Scalia. My students read his work, find it amusing and imitate his truculent style.
