How does the law code show how many people in mesopotamia are unequal?

First, is a law that I find interesting. One law is that if a man strikes another man of higher class, they shall be whipped 40 times in public. There are many other
unequal laws that you can find on google. Another is if a commoner (Lower Class Mesopotamian) committed a crime, their hands would be cut off. This didn’t apply to higher classes.
