Well, I've read this (or rather read section 2 and glanced over the rest) but failed to receive an answer.
Sections like "A judge must avoid all impropriety and appearance of impropriety. A judge must expect to be the subject of constant public scrutiny" or "The test for violation of this Canon is whether the conduct would create in reasonable minds a perception that the judge’s ability to carry out judicial responsibilities with integrity, impartiality and competence is impaired" don't help.
That's almost boilerplate language for most USA judicial CoCs. It also pops up in CoCs for most of our higher elected officials.
The reason it is so broad is because they're trying to cast a wide net, covering as many things as they can think of as well as those that haven't been thought of...yet...while using an efficient amount of text.
All that said, I find it improbable that he'll actually be disciplined for D&D...and I wouldn't want to be the attorney who filed this complaint if he ever had to go before him in the future.
