The Company Interest in Germany and Poland - A Comparative Legal Analysis in the Context of the European Sustainable Corporate Governance Initiative

The project aims to investigate to what extent company law can function as a vehicle for sustainable economic activity and focuses on a German-Polish legal comparison, which is required by both national and European developments to shape the economy and financial markets sustainably.

At the centre of the discussion on company law lies the question of what purposes companies should serve: starting from questioning a pure shareholder value approach, the interests of other stakeholders, such as employees, creditors and consumers, as well as climate and environmental protection interests are increasingly in the focus of legislators in different jurisdictions. The project explores these developments and thereby looks beyond the dichotomy of shareholder and stakeholder model, which seems limited as well as misleading from the perspective of corporate sustainability.

The question of the purpose of a company is addressed centrally in German and Polish company law, as well as in the majority of EU member states, by the legal concept of the interest of the company. This core concept of company law needs to be re-evaluated to effectively meet the current ecological, social and economic challenges that arise under the umbrella of sustainability in an international and intergenerational context.

Project description

Research Object and Research Gap

The legal concept of the interest of the company is regarded as a central object of research in the field of company law. Its study is of particular importance in those jurisdictions where no legal definition exists. Both Polish and German company law - like the majority of company laws in the EU - do not contain such a legal definition.

Research Questions

Given the identified scientific gaps, the main focus of the research question is to discuss the extent to which a German-Polish model of sustainable corporate governance, identified through a profound legal comparison, can serve as an orientation for a future European solution for the harmonisation of a sustainable concept of the interest of the company.

In the first step, this study will focus on the concept of the interest of the company in the respective country, in particular as a connecting factor for a duty of sustainable corporate governance.

The subsequent task is the mutual analysis of the prepared summaries and the comparative law consolidation, which will enable an exegesis of the differences and similarities. This task will be carried out at the planned midterm conference (online). The respective applicants together with their junior researchers will present their country-specific results as well as the first interim results of the legal comparison.

The next task will be to publish the results of the comparative law research in writing. Thereby, the focus will be on a country-specific contribution to the interest of the company in Germany/Poland and a comparative law contribution.

The results of the first phase of the research project will then serve as a starting point for the investigation of European law. In this context, there will be an intensive participation of foreign associated scholars, who will enrich the German-Polish analysis with the EU perspective, to ensure the necessary pluralism of a scientific debate on European harmonisation.

The foreign associated scholars and other junior scientists will have the opportunity to contribute to the final conference of the project, which will be held in Warsaw. The conference proceedings with the contributions of the project participants and the foreign associated scientists will be published afterwards.

14th September 2023: Midterm conference (online) with invited partners from other EU member states to present the results of the first year of the research and communicate the roadmap for the second year of the project.

September/October 2023: Publication of the results of the first year of the research in the form of an article in the international journal.

To be scheduled in 2024: Final conference of the project held in Warsaw.
