Конституция США 
Согласно конституции власть была разделена на три ветки национального правительства: законодательная (Конгресс), исполнительная (Президент) и судейская (Верховный Суд). Каждый получил свою власть.
Эти три установления создали систему сдержек (или сдержок) и противовесов. Эта система позволяет каждой ветви контролировать две других. Например, Президент имеет право наложить вето на акты (законы) Конгресса, но Конгресс может отменить вето в две трети голосов. Но Верховный Суд может объявить недействительными акты конгресса (или любого законодательного органа) или указы президента, если они не соответствую конституции.
