We are here to resolve your most complex disputes. We come up with solutions to issues that have not been resolved before, in a manner that is aligned with our clients’ business goals. We are in the best position to assist our clients in negotiations and mediations when we are engaged early in the process. We have experience in assisting clients with business disputes, regulatory and other investigations, and cases of insolvency. We have a wealth of experience in domestic civil, criminal, and administrative litigation all the way from the first instance to the Supreme Court and Supreme Administrative Court. We are also well-versed in cross-border litigation, including precautionary measures, international assistance, and enforcement cases. We act for our clients in both ad hoc and administered arbitration proceedings, including commercial and investment treaty arbitration, drawing on our experience acting as arbitrators.
We approach every case by listening to our clients and make strategic proposals based on the business’ needs. With a focus on complex and international cases, we provide a dedicated team of experts who litigate and arbitrate disputes across different business sectors in an efficient and result-oriented manner. We seek to understand industry and business drivers and take ownership of the matters entrusted to us. We strive to constantly improve our internal processes by early adoption of technology and focus on case management.
We staff every case with a team whose foremost goal is to resolve the dispute in a manner that furthers the client’s business goals. In mandates requiring specialist expertise, we work with other teams at Hannes Snellman to provide the best advice to our clients. In cross-border cases, we co-operate with foreign top-tier law firms and professionals to achieve the required goals. We enjoy resolving business disputes and working together with our clients in finding new ways to do so.
