This book is about certain risk assessment, risk analysis and risk management from a legal point of view. It discusses five different types of risks that business law needs to cope with nowadays. Some of these challenges are fairly new (artificial intelligence, AI), some are fairly old (limited liability), but they all trigger serious social challenges (like environmental concerns or social responsibility). Some problems are universal, some are global but none can be managed by the locally defined law. The controversy at hand will be decided, but the problem would not even be touched. Law, by definition, belongs to the realm and the existence of statehood, thus, the efficiency, the possibilities and the means of the law are predetermined by this relationship. In any event, risks, and not only the seldom occurrent ones, can be extremely high, and the damages can be overwhelming. Yet, when these risks come about, from a practical social point of view, it might not matter who is right and who is not.
