You express a great deal of anxiety over our willingness to break laws.  This is certainly a legitimate concern.  Since we so diligently urge people to obey the Supreme Court’s decision of 1954 outlawing segregation in public schools, at first glance it may seem paradoxical for us consciously to break laws.  One may 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 Saint Augustine  that “an unjust law is no law at all.”
–Rev. Dr. Martin Luther King, Jr.  “Letter from Birmingham Jail” April 16, 1963

In some ways, it is ironic to use Dr. King as an example to promote nullification and interposition.  Dr. King, in his “Letter from Birmingham Jail” makes one reference to nullification and interposition, and it is not a flattering one.  Many state and local governments cited nullification when they refused to comply with federal legislation and court decisions against segregation.  It is the one unfortunate blight one can find in the nullification movement throughout American history.

One single abuse of the process of nullification, however, should not serve to invalidate the entire nullification movement, which has resisted attacks on free speech, federal slave-catching laws, the destructive war on drugs, and a host of other federal abuses in history and in modern times.  When one considers that the legitimate applications of nullification are rooted in the same beliefs Dr. King expressed, and which have been expressed by people of many different religious beliefs, that “an unjust law is no law at all.” That is, in a nutshell, the essence of nullification.

Had Dr. King lived at the time of the Alien and Sedition Acts or the Fugitive Slave Laws, I believe he most certainly would have found little to criticize about the Virginia and Kentucky Resolutions or the Personal Liberty Acts – the latter of which were an effective tool in the fight against slavery in the 19th Century.

The same Supreme Court that, in 1890, had declared “separate but equal” to be the way in Plessy vs. Ferguson, reversed precedent in Brown vs. Board of Education in 1954.  Many southern states, as well as some northern states, refused to follow that decision, effectively nullifying the Supreme Court’s decision.  Birmingham was one of the most heavily segregated cities in that time.

Martin Luther King, Jr., while not the first, was one of the better known civil rights leaders to engage in civil disobedience against segregation ordinances through boycotts of buses, sit-ins and peaceful demonstrations, some without a permit.  This approach, in theory and in practice, treated the unjust segregation ordinances as being null, void and of no force.  Sound familiar?  Yes, it is the stuff of which proper nullification is made, a fact which Dr. King himself might not have even actively considered, but a fact nonetheless.
