Nullification is the citizens’ final bulwark against an oppressive state, whether that oppression takes the form of unfair or unduly harsh laws, a biased or vindictive judge, or abusive or politically motivated prosecution. In a very real sense, it is the only reason juries even exist. Jury nullification arose as protection against the whims of the king, but there is no less need of it today. In fact, if anything it has now become even more important. Preventing nullification is like bypassing a fuse: it removes a critical check on the abuse of the powerless.
