Supply chain law is intended to encourage companies to protect human rights and environmental protection concerns along their supply and activity chains at home and abroad. Following the LkSG, which came into force in 2023, supply chain law is now also being consolidated in EU law through the Corporate Sustainability Due Diligence Directive (CSDDD) published in the Official Journal on 5 July 2024.
This article examines the impact of business activities in high-risk areas or sectors on due diligence obligations under supply chain law. It then presents initial experiences, risks of the development of obligations and recommendations for action.

The article can be accessed via Beck-Online.

How can globally active companies be encouraged to protect human rights along their supply chains? With the Supply Chain Due Diligence Act (Lieferkettensorgfaltspflichtengesetz, LkSG), which essentially came into force on January 1, 2023, the German legislator has provided an answer based on material due diligence obligations.

In a current article, Leyens and Goetsch present the regulatory approach, functioning and due diligence obligations of the LkSG in a student-friendly way and provide a first insight into the still emerging field of supply chain law.

The article is available to students of the University of Bremen as a free download via the university's online access.

Buchcover

The handbook edited by Klaus J. Hopt, Peter Hommelhoff and Patrick C. Leyens with the title "Unternehmensführung durch Vorstand und Aufsichtsrat: Aktien-, Kapitalmarkt- und Bilanzrecht, Corporate Governance" ("Corporate Governance by the Management Board and Supervisory Board: Stock Corporation, Capital Market and Accounting Law, Corporate Governance"), draws on the interplay of all relevant legal sources (AktG, WpHG, MAR, WpÜG, accounting law, DCGK and others) to show what the management of capital market-oriented companies must do as a minimum and may do as a maximum.

Corporate governance is becoming increasingly difficult for management boards, supervisory boards, managing directors and their advisors. The challenges are also increasingly of a legal and regulatory nature. They are primarily reflected in stock corporation, capital market and accounting law with more extensive European requirements and international expectations. Responding internally with compliance, risk management and adequate, company-specific corporate governance requires great skill.

With its innovative approach, this handbook of corporate governance offers help and suggestions for adapting to new expectations, reforms, risks and obligations in good time. It explains the most important national and European legal regulations in detail and conveys the diverse interrelationships between the areas and levels of regulation (law, code, disclosure obligations). The central theme of the handbook is the so-called “Pflichtenentwicklungsrisiko” (“obligation development risk”). The main focus here is on the realization that code rules, expectations of supervisory authorities or, initially, mere transparency rules often condense into general obligations under company law. It is important for company managers and their advisors to recognize such developments at an early stage and to react appropriately.

The 50 thematic articles in the handbook are written by experienced company managers and leading practitioners and academics. The handbook has been published by C.H.BECK and will soon be available via beck-online.
