Criminal Investigation and Prosecution Procedures in Greece: A Comprehensive Overview with Insights from Cosmos Legal Law Firm

Criminal investigation and prosecution in Greece operate within a structured legal framework shaped by the Greek Constitution, the Greek Penal Code, and the Code of Criminal Procedure. These laws emphasize the rule of law, procedural fairness, and protection of human rights. For individuals or corporations facing criminal allegations, understanding the stages, authorities involved, and available legal safeguards is crucial. In many cases, consulting experienced legal professionals such as Cosmos Legal Law Firm can play a vital role in navigating the complexities of the Greek criminal justice system.

1. Law Enforcement Authorities and Initiation of Investigations

Criminal matters in Greece are generally initiated following a complaint, report, or discovery of a criminal act by law enforcement bodies. The primary investigative authority is the Hellenic Police, though specialized units such as the Financial and Economic Crime Unit (SDOE), Coast Guard, and Cybercrime Division may lead investigations concerning financial crimes, smuggling, maritime offenses, and digital crimes.

Once the authorities receive a report or detect suspicious activity, they begin preliminary investigative steps. These may include witness interviews, evidence collection, surveillance, raids, and obtaining judicial orders for searches or wiretapping. At this stage, the prosecutor acts as a supervisory authority, ensuring investigative measures comply with legal standards.

Legal representation is essential even at the earliest stage, as individuals have the right to remain silent and the right to counsel. Cosmos Legal Law Firm frequently advises clients on how to respond to initial inquiries without jeopardizing their legal position.

2. Role of the Public Prosecutor

Public prosecutors (Eisangeléas) play a central role in Greece’s criminal justice system. They direct investigations, decide whether charges should be brought, and represent the state in court. After reviewing the initial findings, the prosecutor may:

• Order further investigation

• Dismiss the case due to insufficient evidence

• Bring formal charges and transfer the case to an investigating judge

Once charges are filed, the defendant must be notified and given the opportunity to prepare a defense.

3. The Judicial Investigation Phase

In more serious offenses, the case proceeds to an Investigating Judge (Anatkritís). This phase is crucial because it ensures judicial oversight of intrusive investigative measures. The Investigating Judge may order:

• Custodial interrogation

• Pretrial detention

• Bail

• Forensic examinations

• Expert reports

Defendants can present evidence, request witness interviews, or file motions challenging the legality of investigative actions. This stage is often where strategic defense work is most impactful. Lawyers at Cosmos Legal Law Firm assist clients by ensuring procedural rights are respected, preventing unlawful evidence from entering the case file, and advocating for favorable pretrial release conditions.

4. Pretrial Detention and Defendant Rights

While pretrial detention exists in Greek law, it is considered an exceptional measure. Courts evaluate:

• Risk of fleeing

• Risk of committing further crimes

• Risk of tampering with evidence

In many cases, courts impose alternative measures such as bail, travel restrictions, mandatory appearance requirements, or electronic monitoring.

Greek law strongly protects the presumption of innocence. Defendants have the right to legal assistance, interpretation services, access to the case file (after a specific procedural stage), and the ability to challenge prosecutorial actions through appeals or motions.

5. Trial Proceedings

Criminal trials in Greece follow an adversarial format but allow for judicial initiative in questioning. Trials are conducted by panels of judges, and for serious felonies, mixed courts consisting of both judges and jurors may be used.

During the trial:

• The prosecutor presents evidence and examines witnesses.

• The defense challenges the prosecution’s case through cross-examination, expert testimony, and documentary evidence.

• The court evaluates the evidence based on its directness, credibility, and proportionality.

Legal teams such as those at Cosmos Legal Law Firm provide comprehensive trial representation, from preparing detailed defense strategies to examining witnesses and filing procedural objections.

6. Sentencing and Appeals

If convicted, the defendant has the right to appeal. Greek law provides multi-tiered appellate review, ensuring errors can be corrected at both factual and legal levels. Appeals may result in:

• Retrial

• Reduced sentence

• Acquittal

• Partial annulment of the original decision

The Supreme Court (Areios Pagos) handles appeals on points of law, ensuring consistency and legality in court decisions.

7. Cooperation with Foreign Authorities

Greece participates in numerous international cooperation frameworks, including EU instruments, Interpol, and bilateral treaties. Extradition, mutual legal assistance, and cross-border investigations follow strict legal standards. Cosmos Legal Law Firm frequently supports international clients who face parallel investigations or require defense coordination across jurisdictions.
