3institutions created to protect plebeians

Plebians were the nonaristocrats in the Roman Republic, mostly those who do not possess fields, ground. Three institutions created to protect plebeians were The Roman Gens (families that had the same appellation, nomen or forefather), The Roman Curia (the central administrative organism of the Catholic Church), and The Roman Tribes (the voting units of a legislative assembly). 

For a year, the Supreme Court heard less cases out of the worry that the court was split 4-4 after the death of Antonin Scalia.

Once Justice Gorsuch was put on the Court, the Supreme Court knew they had a full complement of judges and could hear cases without deadlock.

That being said, the Supreme Court hears VERY few cases.
