The high court of Region of Murcia has its immediate roots in the old territorial courts that appeared with the Constitution of 1812, a legal text that is the cornerstone of the legal architecture of Spain.  The “Magna Carta” that sprang from the courts of Cádiz granted territorial courts competence for civil and criminal lawsuits in the territory under their authority.  

For the first time, foundations were put in place that would enable judges to carry out their duties independently. Judges had the exclusive duty of judging and enforcement of the judgment, and the Courts or the King were prevented from exercising jurisdictional duties, as well as the legal authority to dismiss pending law suits or initiate expired trials.   

It was not until 1835 that the Ordenanzas de las Audiencias (ordinances of the courts) came into existence. These essential documents divided the courts into three distinct chambers with different jurisdictional powers: two civil courts and one criminal court. 

This judicial organization was respected by substantive law of the judiciary of 1870 and essentially remains unchanged today, aside from the jurisdictions that have been incorporated over time and the evolution of society.
 
The high courts, with their present structure and territorial demarcation, spring from the plan created in article 26 of substantive law of the judiciary of 1985. They were established 23 May 1989. The old territorial courts now became a thing of the past, giving rise to a judicial model that included the autonomous map and was adapted to the requirements of the 1978 Constitution. The high court takes the name of the autonomous community.    

In the city of Murcia and in the Palacio del Almudí, on the twenty third day of May nineteen ninety eight is the date when the Deed of Constitution of the High Court of Justice for the Region of Murcia was executed (link to the original Deed of Constitution) With its constitution the former judicial organisation chart changed, on the basis of the requirements of the Constitution and the Statute of Autonomy. Thus, the judicial district of the Territorial Court of Albacete disappeared, which used to group the Provincial Courts of Albacete, Ciudad Real, Cuenca, and Murcia.

Located at the Plano de San Francisco, the Palacio Almudí used to host, during its history, various functions and for that reason has undergone continuous restructuring; it served at first as the official wheat warehouse, then as the offices of the Criminal Court, of the Municipal Courts and finally as the Provincial Court.

In 1882, with the project of the organisation of a new Criminal Court, the initial idea of adapting the official wheat warehouse as judicial offices was adopted again, a project which materialised in the form of a restructuration and inaugurated on the 2nd of January 1883. The need for grouping all the judicial premises in the same building marked the following reforms, although it was the installation of the Provincial Court which favoured works of a major scale. Thus, in the first third of the twentieth century, once the palace was vacated, a complete reform was carried out. The architect Pedro Cerdán Fuentes, who was entrusted with the works, finished it in 1946.

However, at the end of the twentieth century, all the judicial premises were transferred to the new Hall of Justice located in the Ronda Garay to Murcia Capital, whose project was executed by the architect Germán Álvarez de Sotomayor. This five-floor building, inaugurated in 1975, was designed to host the courts of the city and is the present headquarters of the High Court of Justice.

Since its establishment, the High Court of Justice has had three presidents: Francisco Martínez Muñoz, Julián Pérez-Templado Jordán, Juan Martínez Moya.
