#1 Permission to withdraw is usually granted if the attorney is severely ill, becomes aware of a conflict of interest after taking the case (e.g. a late witness is added to the other side’s list and the attorney has represented this witness, or the witness is a current client, friend or relative), the client refuses to speak with or aid the attorney in the client’s defense. When my mother died the judge would not let me withdraw from a civil case under trial (there was no jury) he adjourned for 2 weeks.
#2 Do I believe juries ignore everything they are told to ignore? NO, but small town educated juries are more apt to follow the judge’s instructions than large city, lower income, less educated juries.
We have a pool of middle aged and senior citizen volunteer jurors in our district who actually enjoy serving on civil trials. They are on a volunteer list. Many are retired educators who take civic responsibility to heart. They tend to both understand boring expert testimony and to follow the judge’s instruction to a T
#3 Jury nullification is a TV and high profile criminal case thing. Most of us practicing attorneys have never run into it.
