The Hungarian Competition Authority (GVH) is actively investigating over 1800 tenders related to 22 different cartel cases. Companies are encouraged to cooperate with the GVH, as admitting to violations can lead to reduced penalties and avoidance of exclusion from public procurement processes.

It is most beneficial for companies to disclose any illegal agreements to the GVH before an investigation is initiated. The first company to approach the GVH may receive full immunity from legal consequences. The GVH has imposed over 25 billion HUF in fines since 2020 for cartel violations, with more than 150 companies currently involved in ongoing investigations.

Cartels are considered the most severe violations of competition law, causing significant economic and societal harm. The GVH conducts extensive inspections, often starting with court-approved raids. Companies found guilty of participating in cartels face substantial fines, potential exclusion from public tenders, and even criminal consequences for their executives.

Companies can apply for leniency before any proceedings begin, provided they fully cooperate with the GVH and submit all available evidence. If a company is the first to report a cartel, it may avoid fines altogether. However, if they report after an investigation has started, they may still receive a reduction in penalties if they provide relevant evidence.

The GVH also offers a confidential reporting system called the Cartel Chat, allowing both businesses and individuals to report cartel activities anonymously. Informants may receive rewards if they meet legal conditions. More information is available on the GVH's website.
