On FreedomWatch, Andrew Napolitano and Lew Rockwell talk about the principles of Nullification, Secession and Interposition.
If the federal government were trying to do something within a state that was unconstitutional, the state government could say – you have no jurisdiction to do something illegal within our state.
Nullification has a long history in the American tradition, and as Napolitano points out, it was used in Massachusetts to resist the abhorrent federal fugitive slave act in the 19th century.
There’s a strong nullification movement growing in the states today.
