Who we are 
and what we do : 

We are partnership of legal, regulatory, and policy experts from different countries based in Zug, Switzerland, one of the main hubs for energy and natural resources globally. We are specialized on legislation and policies governing trade, investment, market functioning, and international relations in the energy sector. Our team members have vast experience as practitioners and as senior academic scholars of energy law and policy. 

Our track records include legal advice to investors and developers of major cross-border energy infrastructure; expert assignments from governments of EU countries as well as international organisations, such as the World Bank; dispute resolution and international arbitration, e.g. under the Energy Charter Treaty; litigation before the Court of Justice of the European Union; strategic guidance and practical support for engagement with European authorities about the application of energy regulation and about emerging policies in the sector; ancillary support, such as monitoring, issues tracking and public positioning.

​We provide actionable guidance for clients inside and outside the EU in view of the continuous roll-out of new legislation and the ongoing transition in energy, climate, and sustainability. Importantly, this includes the fast developing body of EU regulation in these sectors with its vast implications for producers and importers, investors and suppliers, project developers and other market actors.

Our services include legal advice about the specifics of energy regulation and related contractual arrangements as well as preparation, support, and representation in international arbitration and in proceedings at public courts.

To this end, we help clients to anticipate, avoid, and resolve any issues before they become disputes by assessing business models in view of ongoing and upcoming legislative and policy developments, for instance resulting from the all-encompassing “Green Deal” of the European Union. We help detecting emerging challenges, and we offer to facilitate early dialogue with policy-makers and legislators.
