Judges can use shows like South Park as a reference while sitting on the bench. If South Park show will help them make a ruling or make the courtroom understand the ruling they are at liberty to do so. The show which seems to offend a lot of people, it still has some relevance in our society.
No, judges should not reference shows like South Park while sitting on the bench. In my opinion, judges should act in the highest regard, especially while sitting on the bench and referencing shows like South Park is unprofessional. I believe it is unprofessional because of the nature and content of the show.
It is a cultural phenomenon and if the Judge is a fan and finds something in the show that is worth referencing and is helpful for them to get their point across than there is no reason why they cannon use the show as a reference as long as they are not vulgar or obscene.
While shows like South Park make many good points on a variety of topics, it is a cartoon show and not applicable to any real life case over which a judge may be presiding. As such, it is not appropriate for judges to be referencing South Park as they are making or presenting any kind of decision.
