What is generality principle in political science?

This refers to the political belief that laws created by the state need to apply equally to all groups of people in order to avoid any form of discrimination. According to this principle, a law that applies to blacks, for example, must apply to whites as well. Proponents of the generality principle believe that this is essential to uphold fairness and justice in society. However, opponents of the principle believe that the principle would make sure that even bad laws apply to the entire population. This, they argue, would be far worse for the welfare of society as no group would then be able to escape from the destructive effects of poor laws.
