We advised Aurevia Oy, a portfolio company of French private equity sponsor Mérieux Equity Partners, in a strategic reorganisation that involved splitting Aurevia and its parent companies into two independent groups of companies and reorganisation of its existing debt-financing arrangements. Following the reorganisation, the newly formed Aurevia continues as a leading provider of Contract Research Organization (CRO) and Quality Assurance and Regulatory Affairs (QARA) services, while the newly formed Labquality focuses on delivering External Quality Assessment (EQA) services. Aurevia serves operators in the medical devices, in vitro diagnostics and pharmaceutical sectors. Labquality’s customers include clinical laboratories and social and healthcare organisations. The reorganisation positions Aurevia and Labquality to allocate investments more effectively, accelerate growth within their respective customer segments, and respond to evolving market and client needs. The transaction was implemented through multiple parallel demergers and required comprehensive legal and tax structuring across several jurisdictions. Our team supported Aurevia throughout the planning and implementation phases, covering corporate, tax, employment law, and regulatory matters, as well as the optimisation of each group’s financing structure.
Case published 7.4.2026
We successfully represented VR Group before the Supreme Court in a case concerning the meal break practice of commuter train drivers. On 6 February 2026, the Supreme Court ruled in VR’s favour (decision KKO:2026:12), confirming that VR had the right to amend the commuter train drivers’ meal break practice in 2021 by rendering the break unpaid in accordance with the applicable collective agreement. This decision clarifies the interpretation of collective agreements and employment legislation as well as the limits of the employer’s right to direct work. Over 250 commuter train drivers challenged the unpaid meal break practice which VR introduced in April 2021. Before the change, meal breaks had a long history of being paid. The change was based on the train drivers’ collective agreement, which allows for meal breaks to be organised either as paid or unpaid time. The Supreme Court ruled that the scheduling and managing of breaks falls within the core area of the employer’s right to direct work. This increases the threshold for an established practice becoming a binding condition for the parties. Merely following a practice consistently and over a long period of time does not make the practice binding; instead, the employer’s intent to commit to the practice must be clearly evident from the employer’s conduct or other circumstances. As both alternatives – paid and unpaid – for organising meal breaks had been retained in the collective agreement despite other amendments over the years, it could not be considered that VR had intended to commit to the paid break practice and waive its right to direct work as regards break scheduling. It was also significant that the employment contracts explicitly referred only to the collective agreement as regards working time. The Supreme Court deemed that the employees’ paid meal break was not an established term of employment and that VR was entitled to change the practice based on the collective agreement. The employer had the right, by virtue of its right to direct work, to unilaterally change the meal break practice by choosing to apply the other arrangement permitted by the collective agreement.
