In jurisprudence, selective prosecution is a procedural defense in which defendants argue that they should not be held criminally liable for breaking the law because the criminal justice system discriminated against them by choosing to prosecute. In claims of selective prosecution, defendants essentially argue that it is irrelevant whether they are guilty of violating a law, but that the fact of being prosecuted is based upon forbidden reasons. Such a claim might, for example, entail an argument that persons of different age, race, religion, sex, gender, or political alignment, were engaged in the same illegal acts for which the defendant is being tried yet were not prosecuted, and that the defendant is being prosecuted specifically because of a bias as to that class.
