In 1911, the office of the famous architect Ramos de Azevedo was hired, who, inspired by the Palace of Justice of Rome,[2] carried out a project that was accepted by the Court.

[1] The construction works suffered setbacks, the greatest of which occurred during the 1924 São Paulo Revolt, aggravated by the death of the architect Ramos de Azevedo in 1928, which forced the Court to negotiate a new contract in 1929 with successors from his office - Ricardo Severo and Arnaldo Dumont Vilares - through the State Public Works Directorate, under the supervision of Dr. H. Forense, also extended on April 26, 1931.

Due to the high demographic growth in the region and the expansion of the judiciary in the state of São Paulo, there was a need to build a headquarters to house the Court.

Justiniano Batptista Madureira was the last person to be appointed judge of the Court during the period of the monarchy, before the proclamation of the Republic on November 15, 1889.

Although the stone was only laid on that date, the idea of realizing the project was already incubated in June 1911 by the then-Secretary of Justice and Public Security Washington Luís, who years later became the thirteenth president of Brazil.

[1] During the construction works, Ramos had the support of Domiziano Rossi, who designed the Palace based on the Palazzo di Giustizia, located in the city of Rome, Italy.

[4][2] Due to the delay in concluding the project, the population became skeptical and pessimistic about the completion of the building, so much so that the construction ended up being nicknamed "unfinished symphony".

The session was attended by Minister Urbano Marcondes de Moura, who was responsible for delivering the speech, making his remarks about the Palace, often in a lyrical tone.

[6] After a while, shortly after its inauguration and the admiration for its spacious and luxurious structure, the Palace of Justice began to face a period of difficulties, mainly due to the great growth of the city of São Paulo.

Inside the building, more precisely on the fifth floor, one finds the Portrait Room, where images of all those who have been presidents of the Court of Justice are exhibited.

The Salão Nobre ("Noble Saloon") or Ministro Manoel da Costa Manso Room, is a space used for elections, meetings of the Council of the Magistrate, inaugurations of judges, among other activities.

In this space, important trial processes took place, such as that of the former military policeman Florisvaldo de Oliveira, and the singer and musician Lindomar Castilho, who was sentenced to seven years in prison for murdering his second wife.
