Computer-Aided Rationalization of Sentencing
The focus of this research project lies on the potential advantages of a partial rationalization of the sentencing process. This kind of intervention in the existing system would lead to a reduction of judicial discretion and would raise the question of the role human decision-making should play in the sentencing process.
Although the statutory sentencing ranges prescribed by the German Federal Criminal Code (Strafgesetzbuch) apply equally nationwide, there is considerable interregional variation in sentencing. In addition, judges display considerable differences in punitiveness, depending on their specific role in the judiciary and their professional experience. Consequently, there are repeated calls for standardization. Experience has shown, however, that the “margin” or “leeway” theory (Spielraumtheorie) developed by the German Federal Court of Justice (Bundesgerichtshof) in the 1950s is unsuitable for this purpose; it serves only to limit appellate review of sentencing decisions.
In other legal systems, numerous efforts have been undertaken to structure the sentencing process. In the Anglo-American legal world, the use of sentencing guidelines has been growing since the 1980s, and their introduction was discussed in Germany. Additionally, in the United States, for example, computer-based decision support systems, such as sentencing information systems and decision algorithms, have already been tested. With the incorporation of machine learning, these developments could go even further, leading to an increase in technical autonomy. From today’s perspective, however, a complete relinquishing of human decision-making in the sentencing process seems to be neither possible nor desirable, at least in Germany. While human decisions may be prone to error, they may nevertheless display characteristics worth preserving in the context of a rationalization of the sentencing process. The best possible outcome might be a synthesis of computer-based objectivity and final decisions taken by human beings.
