When Justice Kagan speaks to the Ninth Circuit judicial conference, after cutting through all the pleasantries and bromides, her primary objective is to give the left a to-do list. She doesn't sob in her office. She punches through walls. This year, Kagan casually floated an idea that has taken shape: Justice John Roberts could appoint some panel of "judges lower down the food chain" to review allegations of misconduct.
As a threshold matter, she threw Justice Thomas under his RV, and raised Justice Alito up his flagpole. Not even a year after the Court adopted an ethics code–which was part of Kagan's earlier wish-list–Kagan is already saying that the rules are not enough. There have to be teeth!
I'll repeat a few points I've made more times than I can count. Ethics codes are not bright-line rules. They merely offer guidance to judges about how to proceed. All federal judges, even the Justices, can request informal advice from their colleagues, or judges on other courts. Though not binding, judges tend to do what others have done. Judicial ethics body have only very limited tools to enforce ethics codes. These institutions can issue private and public reprimands. In extreme cases, they can refer a judge for impeachment. At that point, it is up to Congress to act. But the ultimate death sentence is to prevent a judge from being a judge.
