I have a scene where a character is applying to be released from prison pending trial. I want an arbitrary / unfair reason for the judge to dislike him. It has to be something that is not justified to keep him in prison (ie, risk of committing further offences, running away, or interfering with witnesses).
I was thinking something like he is rude to the judge/police, he has some character flaw that people don't tend to like etc.
EDIT: In response to the helpful answer below, it occurred to me that I should have pointed out that it would be good for it to be something that the readers wouldn't like either.
I'd really appreciate any ideas!
