Interview with Erle Johnston
QUESTION 5
INTERVIEWER:

OK, GOING BACK TO THE IN RELATIONSHIP TO THE EVENTS AT OLD MISS, WHAT WAS THE DOCTRINE OF INTERPOSITION? CAN YOU JUST EXPLAIN THAT SIMPLY? WHAT WAS THAT BASIS?

Erle Johnston:

The [ doctorate ] of interposition was probably a final straw that Governor Barnett grabbed in an attempt to keep James Meredith out of the University of Mississippi. It was an ancient doctrine whereas you could interpose between the state and the federal government but it had already been outlawed by the courts and of course Governor Barnett was just clutching anything he could in order to perpetuate his fight against the United States Government in that case.
