I wonder what the term is

It's hard to imagine a descriptor for something an attorney can become that is worse than what they already are. (Bam! Lawyer joke! Nailed it!)

There is an old saying among attorneys about what one of their number turns into on becoming a federal judge.

The unflattering term they employ cannot be quoted here.

But whether it will apply to Wendy Vitter will not be the focus of their attention when, as seems highly likely, she joins the bench in New Orleans. In her case, the question must be not how she will treat counsel appearing before her, but whether she will have any idea what she is doing.
