Medios probatorios

Classification of Evidentiary Instruments
📌 Evidentiary instruments (medios probatorios) are procedural tools used by parties to prove the veracity of a claim or fact during a legal dispute.
🔎 The main classifications of evidence discussed include testimonial evidence, expert evidence (periciales), material evidence, and documentary evidence.
⚖️ The judge evaluates these instruments to determine which one most closely aligns with the truth to issue a ruling.

Impact of the 2008 Penal Reform on Evidence Valuation
📜 The 2008 reform introduced a classification system: data of proof (datos de prueba), means of proof (medios de prueba), and proof (prueba).
👂 A key valuation principle is immediacy, meaning only evidence presented in the judge's presence during the hearing can be valued in the final sentence.
🤝 The principle of contradiction requires that both the prosecution and the defense had the same opportunity to present and debate the evidence.
📉 The "auto de vinculación al proceso" (order to link to trial) replaced the formal imprisonment order, requiring a low evidentiary standard to initiate complementary investigation.

Stages of Evidence in the Criminal Process
🔍 Data of Proof are references to investigative actions recorded in the investigation file, used before the judge to determine the linkage to the process (low evidentiary threshold).
📝 Means of Proof are the actual instruments used by parties for the judge to verify facts; these are offered during the intermediate stage through written submissions and oral debate for admission.
🗣️ Proof (Prueba) is the knowledge conveyed to the judge regarding the veracity of a fact, which must be presented and debated in the oral trial under principles of immediacy and contradiction.

Role of the Defense Attorney
🏃‍♀️ Defense attorneys must be proactive during the investigation phase, requesting the Public Ministry to conduct necessary investigative acts, interviews, or expert reports.
🚫 If a means of proof violates fundamental rights (due process, spontaneity, freedom), it should not be granted legal value for sentencing, emphasizing the illegality aspect.
💡 The defense must strategically offer pertinent and useful evidence in the intermediate stage; failing to offer a crucial piece means it cannot be presented or valued in the trial, potentially leading to an indefense status.
⚖️ During the oral trial, the defender must be attentive to direct and cross-examinations of witnesses and experts to support the defense's theory of the case.

Key Points & Insights
➡️ Evidence evolves through stages: Data of Proof (investigation file references) $\rightarrow$ Means of Proof (offered in the intermediate stage) $\rightarrow$ Proof (debated in the oral trial).
➡️ The Public Ministry has an obligation of loyalty and objectivity to provide the defense with all information gathered during the complementary investigation, even if they do not plan to use it in trial.
➡️ In the initial stage for linkage to process, the judge only requires data of proof and applies a free and logical valuation, with a standard sufficient to show the conduct frames the legal norm (jurisprudence 35/2017).
➡️ Parties have the right to refrain from testifying if they have a close familial or cohabitation relationship with someone involved, but if they choose to speak, they are subject to cross-examination.
