The importance of international maritime labour law - both as a component of - ternational maritime law, and in socio-political and economic terms - has been recognised by the IMO International Maritime Law Institute for a number of years. Indeed, the Institute has annually organised a course on maritime labour law with the participation of inter alia the International Maritime Organization, the - ternational Labour Organization, the International Transport Workers' Federation, and the German Shipowners' Association. It was therefore a great pleasure when the authors invited me to introduce their forthcoming monograph on Maritime Work Law Fundamentals: Responsible S- powners Reliable Seafarers. As the title suggests, a fundamental challenge of this branch of international maritime law is to achieve a balance between the interests of the two main stakeholders. Institutionally, the effort to achieve this balance dates back a number of decades with its genesis mainly found in the work of the International Labour Organization. It has to be said that whilst this effort achieved great progress, it has led to a haphazard, plethora of legal instruments.
