The Supreme Court of Justice of the Nation is the Mexican institution serving as the country's federal high court and the spearhead organisation for the judiciary of the Mexican Federal Government. It consists of eleven magistrates, known as ministers of the court, one of whom is designated the court's president.

Zócalo is the common name of the main square in central Mexico City. Prior to the colonial period, it was the main ceremonial center in the Aztec city of Tenochtitlan. The plaza used to be known simply as the "Main Square" or "Arms Square", and today its formal name is Plaza de la Constitución. This name does not come from any of the Mexican constitutions that have governed the country but rather from the Cádiz Constitution, which was signed in Spain in the year 1812. Even so, it is almost always called the Zócalo today. Plans were made to erect a column as a monument to independence, but only the base, or zócalo, was built. The plinth was buried long ago, but the name has lived on. Many other Mexican towns and cities, such as Oaxaca, Mérida, and Guadalajara, have adopted the word zócalo to refer to their main plazas, but not all.
