What is civil disobedience?
Civil disobedience is the intentional breach of legal duty. It is breaking the law. Those who engage in such disobedience lack the legal right to do so, i.e., their behavior is illegal, not legal. However, this sort of disobedience is to be distinguished from mere defiance, rebellion, or criminality. It is disobedience on the grounds of some claimed moral justification or duty.
One expression of civil disobedience is [a] the refusal to comply with and obey a law based on conscience — it is thought that to obey the law is to do evil, thus justifying (or even demanding) disobedience. The perceived evil may be “sin of commission” (being commanded to do wrong) or “sin of omission” (being commanded to refrain from good).
