Prosecutor misconduct involving bias refers to when a prosecutor allows personal opinions, prejudices, or other factors to influence their decision making or behavior in a criminal case. This can include making decisions based on factors such as race, religion, or political beliefs, or failing to disclose exculpatory evidence to the defense due to a personal bias against the defendant. Bias-motivated prosecutor misconduct can be particularly damaging to a fair and just trial outcome, and is generally considered a violation of ethical and professional standards for prosecutors.
