The case involves the government’s procurement of 202 public buses, with four suspects, including Mile Janakieski, then minister of transport and communications, and members of the public procurement commission: Snežana Filipovska Pavleska, Igor Janushev and Juliana Lankulovska Atanasova.

This corruption case was initiated by the special public prosecutor’s office (SPO) based on intercepted materials, with an investigation officially opened on 10 October 2018. Following the dissolution of the SPO, active cases were transferred to the basic public prosecution for prosecuting organised crime and corruption, leading to a three-year delay before the indictment was filed on July 14, 2021.

The prosecution examined two failed tenders and one successful tender (2008 to 2010), with particular interest in the third tender, which included a controversial retro design requirement that awarded an extra 20 points, a condition personally introduced by then-prime minister Nikola Gruevski, in violation of public procurement regulations.

In this tender, two companies submitted bids: Yutong (China) and King Long (a Chinese company, through its representation in Bulgaria). Despite offering a close to €5 million lower bid, King Long was ranked second due to failing to meet the design criteria. The procurement commission favoured Yutong, despite its failure to meet key requirements, such as lacking the ISO 9001:2000 certification and a bank guarantee at the time of opening the bid documentation

Instead of annulling the flawed process, Minister Janakieski signed the contract with Yutong on 14 April 2010, resulting in €4,772,920 of damages to the Republic of Macedonia's budget.

The trial began in March 2022. At the first hearing, Janakieski, Snežana Filipovska Pavleska and Juliana Lankulovska Atanasova pleaded guilty and received two-year suspended sentences, conditional on not committing new criminal offence within five years.

The trial continued for Igor Janushev, who pleaded not guilty. However, just one day after amendments to the criminal code were passed in the parliament in 2023, the court issued another two-year suspended sentence, but due to amendments to the criminal court, the case had reached the statute of limitations.
