The ultimate judicial power of the USA is vested in the Supreme Court and it decides on cases affecting the entire country.
The court has the final say on the most contencious and important rules in the land.
Also, the Supreme Court has been instrumental in passing abortion laws, gay marriage laws, healthcare acts and laws regarding equal rights.
