Barron Trump for SCOTUS
Are there qualifications to be a Justice? Do you have to be a lawyer or attend law school to be a Supreme Court Justice?
The Constitution does not specify qualifications for Justices such as age, education, profession, or native-born citizenship. A Justice does not have to be a lawyer or a law school graduate, but all Justices have been trained in the law. Many of the 18th and 19th century Justices studied law under a mentor because there were few law schools in the country.
