“If a law is unjust, a man is not only right to disobey it, he is obligated to do so.”

Not attributed to Jefferson until the 21st century. May be a loose paraphrasing of a passage from Declaration of Independence (1776): "But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security."
Misattributed
Variant: When injustice becomes law, resistance becomes duty.

“Rewriting unjust laws is a basic human right and fundamental obligation.”

Huey P. Newton (1942–1989) Co-founder of the Black Panther Party

From "In Defense of Self-defense" I (June 20, 1967)
To Die For The People
Context: Men were not created in order to obey laws. Laws are created to obey men. They are established by men and should serve men. The laws and rules which officials inflict upon poor people prevent them from functioning harmoniously in society. There is no disagreements about this function of law in any circle-the disagreement arises from the question of which men laws are to serve. Such lawmakers ignore the fact that it is the duty of the poor and unrepresented to construct rules and laws that serve their interest better. Rewriting unjust laws is a basic human right and fundamental obligation.

“One has not only a legal, but a moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws.”

Context: One may well ask: "How can you advocate breaking some laws and obeying others?" The answer lies in the fact that there are two types of laws: just and unjust. I would be the first to advocate obeying just laws. One has not only a legal, but a moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws. I would agree with St. Augustine that "an unjust law is no law at all."

“One who breaks an unjust law must do so openly, lovingly, and with a willingness to accept the penalty.”

Martin Luther King, Jr. (1929–1968) American clergyman, activist, and leader in the American Civil Rights Movement

1960s, Letter from a Birmingham Jail (1963)
Context: In no sense do I advocate evading or defying the law, as would the rabid segregationist. That would lead to anarchy. One who breaks an unjust law must do so openly, lovingly, and with a willingness to accept the penalty. I submit that an individual who breaks a law that conscience tells him is unjust, and who willingly accepts the penalty of imprisonment in order to arouse the conscience of the community over its injustice, is in reality expressing the highest respect for law.
