The Judge is an elderly man who has spent many years overseeing and moderating the cases that have come to his courtroom. While he is prone to frequent emotional outbursts, often seems confused, is fairly easily swayed one way or another, and frequently says something that makes him look silly- he is an honorable and wise individual who treats every pressing legal matter or concern with the due diligence it deserves and hears out each and every argument until it can go no further.

To me the Judge's voice would be close to the stereotypical "old man voice" which would lend a humorous edge to his ridiculous misunderstandings, but he should also be capable of summoning enough gravitas and authority into his voice to be taken seriously and assures that he can maintain order over the proceedings in the courtroom. So it needs to be SLIGHTLY lighthearted and goofy, but also completely capable of taking the reins of authority and sincerity when necessary.
