Yaneva Gate

In 2015, Bivol started publishing leaked recordings of conversations between two judges from the Sofia City Court, Rumyana Chenalova and Vladimira Yaneva, and the lawyer Momchil Mondeshki: the wiretaps were dubbed Yaneva Gate. The conversations allegedly show influence peddling, illegitimate pressure on the judiciary by Bulgaria's Prime Minister Boyko Borisov, media mogul and politician Delyan Peevski and General Prosecutor Sotir Tsatsarov, corruption, and moral degradation of the courts, including sex against career promotion.^{[9][10][11][12]} According to the Organized Crime and Corruption Reporting Project, "the wiretaps have once again raised questions about the judiciary’s practices, lack of separation of powers, and questionable adherence to rule of law."^[13] Yaneva Gate reached the European Commission which asked Bulgarian authorities to carry out an investigation.^[13] The President of Bulgaria's Supreme Court of Cassation Lozan Panov also publicly called for an independent investigation because Yaneva Gate "put a stain on the courts".^[14] However, Bulgaria's Prosecutor's Office and the Ethics Committee of the Supreme Judicial Council refused to investigate because they deemed the recordings were manipulated.^[15] By contrast, an independent examination by a foreign laboratory which Bivol contacted showed the recordings were authentic.^[15] One of the judges in the conversation confirmed the recordings were authentic too.^[16] Hristo Ivanov, Minister of Justice at the time, has referred to these recordings as а "mega corruption scandal."^[17] In principle, an investigation is difficult because of the vertical structure of Bulgaria's Prosecutor's Office, which means that the General Prosecutor has to investigate himself.^[18]

GP Gate

In 2018, Bivol.bg published their investigation known as GP Gate, which is a joint project with RISE Project Romania. Arguably, it "exposed a complex network of consultants, businessmen and public officials that evidence indicates feasted without public oversight on projects funded by the European Union."^[19] While working on their investigation in September 2018, journalist from Bivol Dimitar Stoyanov and Attila Biro from RISE Project Romania were detained by Bulgarian authorities.^[20] Initially the head of the Directorate for Combating Organized Crime Ivaylo Spiridonov denied that an arrest took place.^[21] Subsequently, the Court of Pernik established not only there was an arrest, but also that the detainment was illegal.^[22] In response to the arrest, the Organization for Security and Co-operation in Europe said it was concerned by the "verbal and physical intimidation" of the journalists by Bulgarian authorities.^[23] The Council of Europe also issued an alert and monitored the case.^[24] Reporters Without Borders publicly condemned the arrests.^[25]

Panama Papers in Bulgaria

In 2018, Bivol.bg gained access to the Panama Papers under an agreement with the International Consortium of Investigative Journalists and subsequently published a story about the offshore company Viafot which is attempting to acquire a key asset of Bulgaria's defense industry, namely the arms producer Dunarit.^[26] The Panama Papers show that Viafot is owned by Alexander Angelov who is the lawyer of media mogul Delyan Peevski.^[26] Previously, other Bulgarian media had reported how mysteriously all state institutions help Viafot acquire Dunarit through illegitimate means.^[27][28] However, the Prosecutor's Office has not started an inquiry.

Boyko Atanasov's Case

Bivol.bg have shed light on the corrupt practices of Bulgaria's Prosecutor's Office by interviewing investigator Boyko Atanasov. Atanasov was subjected to pressure because he exposed the existence of a special secret unit "directly subordinate to General Prosecutor Sotir Tsatsarov, Prime Minister Boyko Borisov and controversial businessman, media mogul and lawmaker Delyan Peevski."^[29] Atanasov claims the unit "deals with concealing crimes and tipoffs against people close to the government, and at the same time, uses signals and tipoffs to blackmail the inconvenient."^[29] Atanasov revealed that "the members of the special unit can’t pursue cases based on their own judgment, but must work according to Tsatsarov’s orders and instructions, otherwise they face salary reduction, disciplinary proceedings and work overload.”^[30] The Organized Crime and Corruption Reporting Project has reported that "Atanasov took a TV crew to show them trash containers at the Sofia Investigation Office filled with shredded business contracts and documents from interrogations, including the collapse of Corporate Commercial Bank, the fourth largest private lender in Bulgaria. He insisted that the documents were destroyed immediately after he gave his first interview to Bivol."^[30]

In 2019, Bivol interviewed a second investigator, Radiana Abdulova, who confirmed there was a special unit at the Prosecutor's Office which whitewashes politicians and attacks critics and opponents of the government.^[31]

Radio Free Europe Bulgaria reported that the girlfriend of Deputy General Prosecutor Ivan Geshev, Detelina Hancheva, with whom he has two daughters is in a business relationship with the main witness in a case in which Geshev is a prosecutor.
