The words "querella" and "denuncia" are often used as if they mean the same thing, especially when a legal news story becomes current. However, from a legal point of view, they are not equivalent, and their differences affect both the procedure and the rights of the person who files them.
Simply put, both serve to inform Justice or the authorities of the possible commission of a crime, but the chosen route significantly changes the role of the person initiating the process.
In general terms, a "denuncia" is a communication of allegedly criminal acts to the competent authority, while a "querella" goes a step further: a formal action before the judicial body through which the person filing it seeks to actively participate in the criminal proceedings.
What is a "denuncia" and how does it work
The Law of Criminal Procedure establishes that any person who witnesses the commission of a public crime can bring it to the attention of the authority. This communication can be made to the Police, the Civil Guard, the Public Prosecutor's Office, or the corresponding court.
A "denuncia" does not generally require a lawyer or a court representative, making it the simplest and most accessible way to report facts to the authorities.
This does not mean, however, that filing a "denuncia" automatically leads to the opening of a trial. The "denuncia" initiates a possible investigation, but it will be the judicial authorities or the Public Prosecutor's Office who determine if there are sufficient grounds to proceed.
Furthermore, the person filing a "denuncia" does not necessarily become an active party in the subsequent criminal proceedings.
What changes when a "querella" is filed
A "querella" has a different legal nature. It also serves to report acts that could be criminal, but it is filed directly with the judicial body and makes the complainant a party to the proceedings.
This is one of the most important differences. The person filing a "querella" does not merely report facts but formally initiates criminal action.
As a general rule, a "querella" requires a lawyer and a court representative, in addition to compliance with specific formal requirements provided for in criminal procedural legislation.
In some cases, a bond may also be required, depending on the procedural circumstances.
The complaint allows for much more direct involvement in the judicial proceedings, with the capacity to drive procedural actions within the corresponding legal framework.
The key differences between both
The most visible difference is practical: reporting is informing; filing a complaint is actively intervening.
Complexity also changes. Reporting is simpler, less formal, and more accessible to any citizen. Filing a complaint requires greater legal formalities.
Another key point is who acts. After a report, the investigation can proceed without the reporter having a significant active role. On the other hand, whoever files a complaint does participate procedurally as an interested party.
Therefore, although both terms are mixed in everyday language, they are not legally the same, and choosing one path or the other depends on the objective pursued and the type of legal action to be undertaken.
