|Corruption by country|
Corruption in Slovenia is examined on this page.
According to Transparency International's Global Corruption Barometer 2013, political parties rank as the most corrupt institution in Slovenia, closely followed by Parliament, the judiciary and public officials. According to the same survey, 77% of the households consider the government's efforts in fighting corruption “ineffective”.
In January 2013, thousands of Slovenians joined the Commission for the Prevention of Corruption and took to the streets, demanding the resignation of Prime Minister Janez Janša and opposition leader Zoran Janković because both had been accused of failing to properly declare their personal assets. The Commission accused both of “systemic, gross and repeated violations of the anti-corruption legislation”. The month after the protest, Janša was ousted in a no-confidence vote. In June 2013, Janša was convicted of corruption in connection with a 2006 defence contract and given a two-year prison sentence. The conviction was unanimously overturned by the Constitutional Court on 23 April 2015. However, Zoran Janković, continued his mandate as mayor of Ljubljana.
On Transparency International's 2021 Corruption Perceptions Index, Slovenia scored 57 on a scale from 0 ("highly corrupt") to 100 ("highly clean"). When ranked by score, Slovenia ranked 41st among the 180 countries in the Index, where the country ranked first is perceived to have the most honest public sector.  For comparison, the best score was 88 (ranked 1), and the worst score was 11 (ranked 180).
According to Transparency International's Global Corruption Barometer 2013, the private sector is scored 3.3 on a 5-point scale (1 being 'not at all corrupt' and 5 'extremely corrupt').
According to the World Economic Forum's Global Competitiveness Report 2013-2014, corruption ranks among the top-five most problematic factors for doing business in Slovenia, after access to financing, inefficient government bureaucracy, restrictive labour regulations and tax rates. However, surveyed executives report that public funds are rarely diverted due to corruption, and the ethical behaviour of companies is considered relatively high.
Contemporary concerns about police corruption are largely reflected by public opinion, which demonstrate widespread consensus that corruption within all public sectors is a "very big problem" in Slovenia. The 2013 Special Eurobarometer on Corruption showed that 76% (the second highest percentage in the EU) of Slovenian participants believed there had been an increase in corruption in the last three years. Furthermore, public opinion suggests that police corruption in particular is a significant issue, which much concern over bribery, and abuse of power for personal gain amongst Slovenian police officers.
Initially, Slovenian legislation did not provide for corruption as a separate offence distinguished from other forms of crime. Corruption is not used as a legal term in Slovenia, instead, the legislation provides for each offence individually as a criminal act. The Prevention of Corruption Act, adopted in 2004, defines corruption as "ever trespassing of the obligated treatment of official or responsible subject in the private or public sector, as well as the treatment of subjects that are initiators of violators, or subjects that can benefit from the violations". Changes within the organisation of policing in Slovenia were brought about initially by the 1991 Constitution, in line with political changes towards a more democratic system with a greater sensitivity towards human rights. These changes, along with the birth of the Constitutional court to enforce these, brought about strict limitations on powers of police to search and seize, as well as more emphasis on the protection of privacy and fundamental rights in criminal proceedings. The judicial control over police powers was further strengthened in the Police Act of 1998, later reinforced by the New Organisation and Work of the Police Act 2013. These acts provide specifically for instances of police corruption. Additionally, the 2013 act allowed an individual to file a direct complaint against a police officer if they thought the act, or failure to act, of the officer violated human rights or fundamental freedoms.
Following the cases of Rehblock v Slovenia (2000) and Matko v Slovenia (2006), a department for the prosecution of officials with special authorisations was established, which removed any police involvement in the investigation of other officers suspected of committing criminal offences. Since this recent introduction, there has been increased investigation and action taken for police offenders. In 2011, the department conducted 80 investigations, out of which 19 police officers were dismissed as a result of the suspicion of them committing a criminal offence.
Lobinkar & Mesko (2015) found that within a sample of 550 Slovenian police officers, 23.6% agreed that covering up a police DUI was 'not all that serious'. Additionally, 34% of respondents claimed that they would not report another police officer who had engaged in conduct such as receiving free meals, gifts from merchants, police DUI and verbal abuse. While this study demonstrated a trend in Slovenian police officers to ignore less serious forms of police corruption, there is agreement (59.1-75%) that police integrity within the Slovenian police work environment is generally high.Within the wider context of the European Union, corruption continues to be an economic burden. Aside from the consequences within each member state, corruption reduces levels of investment, obstructs the fair operation of the Internal Market and has a negative impact on public finances. It is estimated that approximately 1% of the EU GDP is made up of economic costs incurred by corruption. Specifically, an estimated los of 1.5 and 2% of the Slovenian GDP is incurred as a result of corruption. Slovenia has administered substantial improvements to their legal framework to address the issue of police corruption among Central and Eastern European Member States. However, issues with the effective enforcement of these anti-corruption measures still remain, due to "weak control mechanisms" administered by the government. Lobinkar & Mesko's 2015 survey demonstrates a high level of police integrity strictly connected to the 'code of silence' in the police community. Therefore, anti-corruption strategies related to changing perceptions and moral beliefs about the seriousness of corruptive police conduct may be the most effective at improving Slovenia's anti-corruption enforcement.
