From the Wikipedia article I posted:

Recent court rulings have contributed to the prevention of jury nullification. A 1969 Fourth Circuit decision, U.S. v. Moylan, affirmed the right of jury nullification, but also upheld the power of the court to refuse to permit an instruction to the jury to this effect.[21] In 1972, in United States v. Dougherty, 473 F.2d 1113, the United States Court of Appeals for the District of Columbia Circuit issued a ruling similar to Moylan that affirmed the de facto power of a jury to nullify the law but upheld the denial of the defense's chance to instruct the jury about the power to nullify.[22] In 1988, the Sixth Circuit upheld a jury instruction that "There is no such thing as valid jury nullification."[23] In 1997, the Second Circuit ruled that jurors can be removed if there is evidence that they intend to nullify the law, under Federal Rules of Criminal Procedure 23(b).[24] The Supreme Court has not recently confronted the issue of jury nullification.
