Contact details

I specialise in dispute resolution. My principal areas of practice include both domestic and international arbitration and litigation.

I have represented clients in various large-scale commercial disputes that have, in recent years, focused particularly on the construction and energy sectors. I have also advised clients in commercial disputes relating to, among other things, the sale of goods and IT.

I have completed court training at the District Court of Helsinki. This training gave me valuable practical experience in court procedures, which has helped me in assisting clients with the disputes they are facing.

Finnish manufacturing company – Arbitration proceedings under the SCC rules
We successfully represented a Finnish manufacturing company in arbitration proceedings under the SCC rules against a global construction company. The dispute was governed by Finnish law and the seat of arbitration was Stockholm, Sweden. The dispute mainly concerned the termination of an erection contract and the right to compensation for delays of the project and for cost increases due to Russia’s invasion of Ukraine. The main questions in dispute were the lawfulness of the termination of the erection contract as well as the consequences of the termination such as the right to costs to complete the project after termination, the right to liquidated damages for delay of the project and adjustment of contract price due to cost increases. The total value of the dispute exceeded EUR 15 million.

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.

Gasum and C&S – A Shared Course to a Cleaner Future
Over the past seven years, Gasum has transformed itself from a traditional Finnish gas distributor to a modern energy company and significant circular economy operator in the Nordic countries. Castrén & Snellman has stood by Gasum’s side throughout this journey.  When General Counsel Tiia Ryhänen joined Gasum in 2013, the company was still a traditional gas distributor. ‘We closed our first liquefied natural gas (LNG) acquisition in 2014. In the seven years since, Gasum has transformed itself into a modern, international energy company and circular economy operator’, Ryhänen said. This major shift has taken place through a series of corporate transactions. Ryhänen has been involved in every one of them over the past seven years. ‘It has been exciting to be a part of creating something new and expanding the company. I have particularly enjoyed welcoming many new people onto the Gasum team.’ ‘Like an Extension of Our In-House Team’ Castrén & Snellman Attorneys has been Gasum’s partner from the very start. ‘C&S has stood by our side throughout this journey. We have a strong partnership. C&S really understands how we handle acquisitions. We always want to act in a way that respects the people on the other side of the table’, Ryhänen said. Ryhänen’s team includes three other in-house lawyers. Since last August, the team has also had one of Castrén & Snellman’s lawyers ‘on loan’, i.e. on secondment. ‘C&S is like an extension of our in-house team. We work with at least one of their lawyers nearly every week. We regularly talk about the best ways to move forward in assignments. We can trust them to always deliver on their promises.’ Towards a Carbon-Neutral Society Gasum is a Nordic gas sector and energy market expert. The company’s strategy is to expand the natural gas market. Our work has a shared purpose: cleaner energy. ‘The demand for natural gas and biogas is growing fast, because fighting climate change requires switching to cleaner solutions. We are building a bridge towards a carbon-neutral society together with our customers and partners.’ In practice, this goal means that Gasum will have to expand its network of gas filling stations, increase its production and sourcing of biogas and help its customers reduce their emissions. ‘We have also expanded our operations on the electricity market. Last September, we entered into a long-term wind power deal with ABO Wind Oy for the output of their wind park. In 2023, we will begin selling our customers renewable wind power produced in Kestilä.’ Gasum’s Journey to a Modern Circular Economy Operator with C&S 2020 Gasum acquires the entire share capital in Swedish biogas producer Skövde Biogas AB from Torran Gas Holding AB. 2019 Gasum acquires AGA’s Clean Energy business and Nauticor’s Marine Bunkering business from Linde AG.

Gasum acquires Enegia Group Oy’s energy market services business. 2017 Gasum increases its shareholding in Skangas to 70%.

Gasum acquires 100% of the shares in the Swedish biogas producer Swedish Biogas International. The acquisition makes Gasum the leading producer of biogas in the Nordic countries. 2016 Gasum acquires the Biotehdas biogas plant chain owned by Taaleritehdas Biofactory I Ky Private Equity Fund.

FinnHEMS – Set-Aside Proceedings of an Arbitral Award
We represented FinnHEMS Oy, the company in charge of Helicopter Emergency Medical Services (HEMS) operations in Finland, in set-aside proceedings. In 2016, an arbitral tribunal rendered an award dismissing the claims presented by FinnHEMS against one of its service providers. The arbitral tribunal accepted that the service provider had breached the agreement, but decided not to award any compensation to FinnHEMS, as the arbitral tribunal considered FinnHEMS to have failed to give notice of the breaches within a reasonable time. However, the service provider had not invoked failure to give notice as grounds for disputing the claim during the arbitration. Consequently, FinnHEMS initiated set-aside proceedings in the District Court of Helsinki. The District Court of Helsinki accepted FinnHEMS’ action and set the award aside. The service provider appealed to the Helsinki Court of Appeal, which also found in favour of FinnHEMS. Both the District Court of Helsinki and the Helsinki Court of Appeal accepted FinnHEMS’ argument that the arbitral tribunal had failed to provide FinnHEMS with sufficient opportunity to present its case and had exceeded its jurisdiction when basing its award on grounds not invoked by the parties in the arbitration. The Supreme Court did not grant the service provider leave of appeal, making the decision by the Helsinki Court of Appeal final.  The threshold for a court to set aside an award is high. Arbitral awards are meant to be final and can only be challenged on very limited grounds. All in all, there is very little legal praxis available relating to set-aside proceedings and even less so where an arbitral award has actually been set aside. Nevertheless, FinnHEMS was able to show that the arbitral tribunal had exceeded its jurisdiction and failed to provide FinnHEMS with sufficient opportunity to present its case to such a degree that the arbitral award was set aside. The final decision by the Helsinki Court of Appeal is noteworthy and rare in Finland and provides good guidance for future cases with respect to the limits of the powers of arbitral tribunals.

S-Bank – Issuance of EUR 150 million SNP notes and tender offer for notes maturing in 2026
We advised S-Bank Plc in its issuance of a EUR 150 million Senior Non-Preferred Notes and on the tender offer of its EUR 150 million Senior Preferred MREL Eligible Notes maturing in 2026. The tender offer required prior approval from the Finnish Financial Stability Authority based on the Commission’s regulatory technical standards (EU) 2023/827. The Stability Authority granted S-Bank a permission for repurchases of the notes. Based on the permission, S-Bank replaced the notes with own funds or eligible liabilities instruments of equal or higher quality at terms that are sustainable for the income capacity of S-Bank. According to the final tender offer results published on 10 December 2025, S-Bank repurchased a total of EUR 97.9 million of the notes. The new notes will pay a floating interest rate, which is determined based on 3-month Euribor added with a margin of 1.35 per cent. The notes were issued on 11 December 2025 and listed on Nasdaq Helsinki Ltd. The maturity date of the notes is 11 December 2029. The purpose of the issue was to meet the minimum requirement for own funds and eligible liabilities (MREL) and to finance the bank’s activities.
