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.

The Finnish State – The Court of Appeal dismissed the action of Peter Fryckman against the Finnish State
We successfully advised the Finnish State/the Ministry of Justice in a declaratory action in which the Helsinki Court of Appeal dismissed the claims of businessman Peter Fryckman and confirmed the non-existence of an arbitration agreement. Fryckman had filed for arbitration before The Hague’s Permanent Court of Arbitration (PCA) in February 2018. The request was based on a claim that the Finnish Minister of Justice had signed a consent to arbitration between Fryckman and the Finnish State in the PCA. The State denied the existence of an arbitration agreement in its response to the request for arbitration and refused to appoint its own arbitrator. The Secretary-General of the PCA deemed that the document titled ‘Declaration of Consent’ was too ambiguous and general in nature, and therefore he could not appoint an arbitrator for the State to an arbitration conducted under the PCA Arbitration Rules 2012. After this, Fryckman requested that the District Court confirm the existence of an arbitration agreement between him and the Finnish State, under which disputes between the parties concerning tax and debt collection actions against Fryckman and his companies, as well as the resulting damages, would be settled before the Permanent Court of Arbitration in The Hague.  However, the District Court dismissed this action because the consent signed by the Minister of Justice was general in nature, its content was unspecified, and it was unclear whether the consent was even a matter that could be arbitrated. Furthermore, the District Court deemed that the consent signed by the Minister of Justice and the plaintiff’s application for commencement of arbitration were not identical and reciprocal, and there was no evidence of an agreement between the parties as to the commitment to and content of the agreement. Fryckman appealed the District Court’s decision to the Court of Appeal, but in its judgement of December 2022, the Court of Appeal deemed that there was no cause to amend the District Court’s decision. The Court of Appeal found that the expression of will in the document titled ‘Declaration of Consent’ had not been made in accordance with the Ministry of Justice’s procedure for presentation and decision-making. According to the Court of Appeal, due to this key fault in the Ministry’s procedure, the free-form expression of will by the Minister did not have a binding effect on the parties. The Court of Appeal remarked that the plaintiff’s actions bore characteristics of an intent to bypass the Ministry’s customary procedure for decision-making. The Court of Appeal also noted that the Minister’s expression of will was encumbered by deficiencies in arbitrability and the subject matter of the consent as stated by the District Court, and referred to the grounds stated by the District Court in other respects as well. On 5 May 2023, the Supreme Court ruled that no leave to appeal would be granted, and the judgment of the Court of Appeal is therefore final.

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.

Finnish Broadcasting Company – Appeal in a defamation case dismissed by the Monegasque Supreme Court
We successfully advised the Finnish Broadcasting Company, Yleisradio Oy, and its Editor in Chief in a defamation case before all levels of the Monegasque judiciary. The case concerned four articles published by Yleisradio in 2022, two of which were in Finnish and two in English. The counterparty was of the opinion that the claims made in the articles violated his honour and brought defamation charges against Yleisradio and its Editor in Chief in Monegasque courts. In addition, he claimed damages totalling EUR 100,000 and demanded the removal of all allegedly defamatory content under penalty of a fine. We challenged the jurisdiction of the Monegasque courts in the matter, as the articles were not directed at a Monegasque audience and, contrary to what the counterparty claimed, jurisdiction could not be based solely on the fact that the articles were published in English on the internet where they were available for all and could be translated into French using a browser functionality. Furthermore, we presented comprehensive arguments stating that the facts presented in the articles were truthful, presented in good faith as required by Monegasque legislation, and based on thorough research. We also highlighted that the counterparty’s actions constituted so-called forum shopping, i.e. the desire to have the case heard in a court he believed would be most favourable to him. The claim was heard by all three levels of Monegasque courts, as the counterparty appealed the judgments of the lower courts. The courts of first and second instance had deemed that the Yleisradio articles in question were not directed at a Monegasque audience, and the Monegasque courts were therefore not competent to hear the case. The Supreme Court of Monaco (Cour de Révision) stated that there were no grounds to link the allegedly defamatory claims to the country. Even though it was possible to access the online articles from Monaco as well, this did not mean that the articles were published in Monaco. This being the case, the Supreme Court of Monaco deemed that the local courts did not have jurisdiction to rule on the case and dismissed the counterparty’s appeal against the Court of Appeal’s decision. The Supreme Court’s decision is fundamental in upholding the freedom of expression in Europe. The opposite outcome would have encouraged similar intimidation lawsuits in countries favourable to the plaintiff, with the purpose of restricting dialogue and silencing critical voices. The unpredictability of judicial power and the risk of extensive – and expensive – trials could create an atmosphere of fear and increase self-censorship of those exercising their freedom of expression, especially journalists, other media professionals and researchers. The decision also reinforces the principle that forum shopping is not allowed. The Supreme Court’s decision is final.
