Unfortunately you are dealing with the government..
Picture if you will the biggest “geek” classmate in your school. The one that gave a presentation at the Science Fair that even the judges had to check resources....The musician that knew great details of the Classics...or the girl who read every novel in the library...
Now put a law degree and a copy of the constitution in front of that type of individual and multiply it by nine. One is not going to be outdone by the other.
Very seldom do they get to work on a real bona fide constitutional issue, and they are going to make sure every section is done to perfection......
It is their chance to go down in history....To be THE justice with THE opinion that is quoted forever. THIS is what they have waited a life time to expound upon, a culmination of their “nerdiness”...No way are they going to mess it up or miss their big chance.
