No, the doctrine of state nullification has never been legally successful in invalidating major federal laws, though it led to political compromises like the Compromise Tariff of 1833, and jury nullification (where a jury ignores the law) has seen success in specific cases, especially during historical resistance to unjust laws, but isn't state-level nullification. Major attempts, like South Carolina's nullification of federal tariffs, failed constitutionally, with the Supreme Court ultimately rejecting the theory, notably in Cooper v. Aaron (1958).

Was the Nullification Crisis successful?

Why do judges dislike jury nullification?

Judges often oppose jury nullification because it undermines the rule of law, creates legal inconsistency, and allows jurors, who lack legal training and accountability, to make arbitrary decisions, potentially acquitting guilty people or convicting the innocent, thereby perverting the system they've sworn to uphold, though proponents see it as a vital check on unjust laws or application. They view it as jurors overstepping their role, leading to unpredictable and unequal justice, conflicting with their duty to apply the law as written. 

Can a lawyer tell the jury about jury nullification?

Does jury nullification have to be unanimous?

What if one juror disagrees?

If one juror disagrees in a criminal case requiring unanimity, it leads to a hung jury (or deadlocked jury), resulting in a mistrial, meaning no verdict is reached, and the prosecution must decide whether to retry the case with a new jury, offer a plea deal, or drop charges. In civil cases, rules vary, but often a non-unanimous verdict is allowed, so one dissenter might not stop a decision, though a full deadlock still causes a mistrial.

Are civil cases easier to win?

Yes, civil cases are generally considered "easier" to win than criminal cases because they have a much lower burden of proof, requiring only a "preponderance of the evidence" (more likely than not, or 51%) compared to the "beyond a reasonable doubt" standard in criminal law, meaning less certainty is needed to win. However, "easier" is relative; civil cases still demand strong evidence and preparation, with success rates varying significantly by case type (e.g., car accidents are higher than medical malpractice). 

Do any OJ jurors regret?

Simpson jurors' feelings about their "not guilty" verdict are mixed, with some, like Yolanda Crawford, remaining comfortable with the decision due to "reasonable doubt" created by police misconduct (especially Mark Fuhrman's perjury and racism) and mishandling of evidence, while others have expressed regret, with some feeling they let a murderer go free due to the Rodney King case's influence or errors like the glove demonstration, though some jurors deny the King case played a role in deliberations.
 

What did OJ whisper after his verdict?

After his 1995 acquittal, O.J. Simpson whispered to his lawyer, Robert Shapiro, "You had told me this would be the result from the beginning. You were right".
