Spanish to English Law/Patents Law (general) Puerto Rican Spanish to U.S. English

This is a court document. It starts out as follows:

Estado Libre Asociado de Puerto Rico
Tribunal de Primera Instancia
Centro Judicial de Aguadilla
*Sala Superior*

El Pueblo de Puerto Rico

vs
**************

I saw a similar kudoz question where it was translated as "Superior Court", but I'm translating Tribunal de Primera Instancia" as "Trial Court" and it seems a little strange to me to have "Trial Court" and then "Superior Court" right after it.

I did a google search and found one site that translated it as "High Chambers", but when I googled "High Chambers", I didn't find anything having to do with courts or law.

I'm hoping there is a term that is commonly used in the legal system. Thanks in advance for your help!
