  1. Dispute Resolution

Contact details

I specialise in dispute resolution. My practice covers both international and domestic arbitration and litigation as well as alternative forms of dispute resolution.

I have represented our clients before tribunals and the Finnish courts in a variety of commercial and corporate disputes. These disputes have related to, for instance, antitrust damages claims, construction projects, mergers and acquisitions, shareholders’ agreements, international trade, and trade secrets. I have also acted as counsel in investor-state arbitration proceedings. My industry experience includes construction, electronics, energy, the food industry and technology, among others.

In addition to a law degree, I hold a M.Sc. degree in Economics and Business Administration and have also completed court training. My educational background supports my practical experience and helps me understand how to best advise our clients when disputes arise. Prior to joining Castrén & Snellman I also worked on questions related to corporate law at an international audit firm.

I am a regular speaker in topics related to dispute resolution and an active member of the Finnish arbitration community. Currently I serve as chair of the Young Arbitration Club Finland, a Finnish association for arbitration practitioners aged 40 or under.

A large Finnish group – Construction contract dispute
We represented a mutual real estate company belonging to a large Finnish group in arbitration proceedings against a construction company. The arbitral tribunal rejected the construction company’s claims in their entirety and ordered the construction company to reimburse our client for the costs of the arbitration proceedings in full. The dispute concerned the contract price under the construction contract, which was agreed to be determined on the basis of our client’s yield requirement and the rent under the lease agreement for the building in question. The parties disagreed on the indexation clause applicable to the rent adjustment and its impact on the contract price.

Finnish building company – Settlement of large-scale construction dispute
We successfully represented a major Finnish construction company in a dispute and settlement negotiations concerning a large construction project. The dispute mainly concerned liabilities for additional and change works as well as project delays, and the value of the claims of the parties was approximately EUR 50 million.  If the case had not been settled, it would have been one of the largest construction disputes ever tried in the Finnish courts. The projected number of hearing days was unprecedentedly more than 300 days. To find an amicable solution to the extensive dispute, the parties engaged in settlement negotiations and court mediation. Eventually, the parties reached an amicable settlement to the full satisfaction of our client and thus the parties avoided the costs and risks of an extensive trial.

Valio – Competition Damages Case
We represented Valio Oy, a major dairy company, in a follow-on competition damages case related to the Supreme Administrative Court’s decision on abuse of a dominant position. In 2014, the Finnish Market Court fined Valio for predatory pricing in the Finnish fresh milk market. In 2016, the Finnish Supreme Administrative Court upheld the Finnish Market Court’s decision. Following the Market Court’s decision, Arla Ltd and five Finnish dairy companies claimed compensation from Valio for damage allegedly suffered due to the competition law infringement. The capital amount of damages claimed was, in aggregate, more than EUR 100 million. Four of the six claims, including Arla’s claim, were settled prior to the main hearing. A seven-week main hearing of the remaining two damages claims, which amounted to EUR 30 million, was held in the Helsinki District Court in March 2019. The District Court gave its ruling on June 2019 and awarded the two remaining claimants a total of EUR 8 million in damages, which is less than one-third of the amount of the claims in question. The parties did not appeal the decision, which is now final. This matter is noteworthy as it is the first significant follow-on damages case relating to abuse of dominance in Finland and one of only a few in all of Europe. Valio Ltd is a brand leader and the biggest dairy business in Finland and a major player in the international dairy ingredients market. In 2018, Valio’s turnover stood at EUR 1.7 billion, and it had 4,200 employees globally.
