Albie Sachs: The repression from 1962-63 onwards changed everything in the courts as far as political cases were concerned.  You still had very erudite judges who had all the punctilio of legal form in the higher courts, but the law was transformed now into an instrument of oppression. You could be plucked out of your home, your work, walking in streets, in my case going into my office, at the whim of a senior police officer.  No charge. Locked up in solitary confinement, no knowledge of why you’ve been locked up at all. No contact with lawyers, no contact with families, just you, yourself, alone in a little concrete cube.
