Who prosecutes election-related criminal offences?

Romania
Election offenses of a criminal nature are defined in the Election Law. Violations are investigatedunder the supervision of the prosecutor in a corresponding jurisdictionupon reports or referral to the police, or upon the initiative of theprosecutor based on public reports. The investigation of election offenses may be taken over byhigher-level prosecutors if the offense occurred in multiple jurisdictions orwhere the investigation requires more resources then are available to thelower-level prosecutor. Although election offenses are punishable withup to five years in prison, the vast majority of cases are settled through theissuing of a fine by the prosecutor. While no investigations were opened withthe High Court Prosecutor in the pre-election period, the ongoing investigationof incidents from the local elections and the referendum received much mediacoverage and is reported to have served as a deterrent on voters and electionofficials.
