Judges typically have a list of factors it considers before dismissing a juror, but at the top of the list is that person’s ability to remain impartial when hearing evidence. Massachusetts Justice Kimberly Budd wrote as much, saying in her decision: “Asking a prospective juror to put aside his or her preconceived notions about the case to be tried is entirely appropriate (and indeed necessary); however, asking him or her to put aside opinions formed based on his or her life experiences or belief system is not.”
