  abstract  = {As part of the current process of de-formalization in international law, States increasingly chose informal, non-legally binding agreements or 'Memoranda of Understanding' ('MOUs') to organize their international affairs. The increasing conclusion of such legally non-binding instruments in addition to their flexibility, however, also leads to uncertainties in international relations. Against this background, this article deals with possible indirect legal consequences produced by MOUs. It discusses the different legal mechanisms and avenues that may give rise to such secondary legal effects of MOUs through a process of interaction with, and interpretation in line with, other (formal) sources of international law. The article further considers various strategies how to avoid such eventual possible unintended or unexpected indirect legal effects of MOUs when drafting such instruments and when dealing with them subsequent to their respective 'adoption'.},

  abstract  = {This paper consists of two parts: In the first part, some of the challenges with which the Internationaal Criminal Court is currently confronted are being presented. First of all, the article will describe the current state of the International Criminal Court and the Rome Statue. Afterwards, the article analyses the Court's efforts to deal with cases against third-country nationals and the challenges it is facing in that regard. In addition, the Court's case law will be analyzed in order to determine an increasing 'emancipation' of the case law of the International Criminal Court from international humanitarian law. The second part of the paper will briefly discuss the role of domestic international criminal law and domestic courts in the further development and enforcement of international criminal law. As an example of the role that domestic courts may have in clarifying classic issues in international law, the judgment of the German Supreme Court of January 28, 2021 (3 StR 564/19), which deals with the status of costumary international law on functional immunity of State officials before domestic courts, shall be assessed.},

  abstract  = {Currently a political debate is ongoing in Germany as to whether Germany should, following the example of several other European countries such as France and the Netherlands, adopt a Supply Chain Act (Lieferkettengesetz). If adopted, the act in question would impose due diligence obligations on German corporations to prevent human rights violations taking place in their respective global supply chains. It is against this background that the article examines the preconditions that must be met in order for such act to be eventually compatible with both, German constitutional and international law. The authors further deal with the question whether Germany might even be obliged under international, as well as under German constitutional law, to enact such a supply chain law in order to protect the human rights of workers employed by companies forming part of the global supply chains of German companies. As far as German constitutional law is concerned the article notably deals with the question whether it is the Federal parliament that may adopt such a law also taking into account the competencies of the European Union in the field, and what are the requirements of legal specificity and proportionality in order for the draft law to stand constitutional scrutiny. The authors further offer detailed suggestions how corporate due diligence standards might be best provided for in the envisaged law and propose a risk analysis approach that varies not only according to specific countries and sector-specific characteristics, but that by the same token also takes into account the ability of the respective German company to exercise an appropriate due diligence standard when it comes to human rigths issues arising within the framewok of their supply chain. As far as the substantive human rights standards are concerned that should serve as benchmarks for the envisaged Supply Chain Act the authors propose to rely on, and refer to, those instruments such as the ICCPR and the CESCR, as well as the ILO treaties containing core labour standards, that enjoy almost universal acceptance and reflect customary international law.},
