Natural Law vs. Legal Positivism: Philosophical Foundations
Quick fact
In 1945, German courts were asked to judge Nazi-era informers who had caused the deaths of fellow citizens by reporting them to the Gestapo. Legal positivists say those informers simply obeyed valid law, while natural lawyers argue that such 'laws' were so immoral they were never law at all.
