Kastell provides legal advice and assistance on all aspects of EU and competition law, including state aid and internal market law. The team is considered one of the top teams in this area in Sweden, with extensive experience of assisting clients in matters before competition authorities, regulatory authorities, and courts, including the Patent- and market court, the Swedish Supreme Court and the EU courts. The team assists companies and investment banks with feasibility analyses and notifications of mergers & acquisitions, and advises undertakings on competition law issues affecting corporate policy and strategy, including internal competition compliance audits and programmes. The team works closely with Kastell's dispute resolution team, leveraging the experience of that team to ensure the highest level of expertise in competition law-related disputes.
The regulatory advice and compliance team is an offshoot of the EU and competition law team, comprised of the same team members. Kastell’s team is highly experienced in advising on, and liaising with, the relevant authorities in relation to regulatory questions, including product safety, foreign direct investments (FDI) and protection of national security.
