Zambians may not be a very litigious people like Americans or Kenyans. I think Chiluba devastated the Civil Society the way Uhuru is trying and Kibaki attempted (through coopting).
That law is inherently illegal. One can not legislate a law to target an individual. There are protections against specialized treatment by the law, not to mention such an obvious and obnoxious discrimination.
Besides, Kaunda had already been President for almost three decades. So what was the law curing if no malady had manifested itself in the three Kaunda decades? Somebody should have rushed to court to have the law thrown out. I know Chiluba became a dictator worse than any Zambia will ever have but he did leave office but the law stayed. There is something wrong.
What a strange law. Why should where someone's parents were born matter if you yourself were born in a country that your parents had moved to? If America had this law, Obama would never have seen the insides of the Oval office.
