The WEKO dramatically expanded its cartel investigation against construction companies in Canton Jura in February 2026: from originally 6 to 20 suspected companies. The accusation is illegal price-fixing and bid allocation over a period of nine years (2016–2025). This potentially affects over 150 public and private tenders and could have resulted in significant price overruns and economic damage. The investigation is expected to take approximately three years.

Detailed Summary

The Competition Commission opened proceedings in November 2025 against six companies on suspicion of bid-rigging. Based on investigation results to date, the suspicion has intensified and the investigation has been expanded to a total of 20 construction companies. These are accused of coordinating their offers and prices over several years – both for public procurement and private contracts.

The suspected cases relate to more than 150 public tenders in civil and building construction from the period 2016–2025. Bid-rigging is prohibited under cartel law and demonstrably leads to higher prices, reduced efficiency, and innovation inhibition. The affected companies are predominantly small to medium-sized construction firms from the Jura region, including established names such as André Chaignat et Fils SA, Marti Arc Jura SA, and Louis Vernier SA.

According to WEKO standards, the investigation will take approximately three years. All accused companies are presumed innocent until a cartel law violation is proven.

Key Points

  • 20 construction companies in Canton Jura suspected of illegal price-fixing
  • Over 150 public tenders (2016–2025) potentially affected
  • Bid-rigging leads to price increases, inefficiency, and innovation inhibition
  • Investigation duration: approximately 3 years
  • Presumption of innocence applies to all accused companies
