Prosecutorial misconduct can be defined as the use of deceptive or reprehensible methods to attempt to persuade either the court or the jury. Prosecutorial misconduct is a procedural defense; via which, a defendant may argue that they should not be held criminally liable for actions which may have broken the law, because the prosecution acted in an "inappropriate" or "unfair" manner. Such arguments may involve allegations that the prosecution withheld evidence or knowingly permitted false testimony. This is similar to selective prosecution.
