The Supreme Court has exclusive discretion over its caseload and hears about a hundred cases per term, which begins on the first Monday of October and ends in late June. 

It receives about 7000 review requests over decisions each year, called certiorari requests, which at least four justices go through.

The decision-making process is first made in secret voting, and then the official decision is issued.

• If the voting is in favour of the Chief Justice, the justice who will issue the official decision is chosen by him/her.
• If the Chief Justice is in the minority, the longest-serving member of the majority will create the official decision.

Executive administrative and judicial actions by the Congress and the State are subject to be reviewed by the court, through the process of judicial review. The Supreme Court has nullified state laws and regulations that were unconstitutional or discriminatory.

There are various clauses and amendments, like the Fifth Amendment or the Fourteenth Amendment that have been used to protect people and companies against repressive or draconian acts of the government.
