Also, just because an attorney is an attorney or a judge is a judge doesn’t mean they are familiar with every branch of law.
In every court I’ve worked I very often had to advise or correct attorneys how to do stuff. Like basic stuff.
Attorneys used to working Supreme would call and ask the price for filing a motion. In lower civil mostly all filings are free! But this very basic question I’ve answered 1000 times. (As one example)
The same holds true with judges. A judge versed in one court is not as knowledgeable in another section of law.
