I was at the German National Library the other day picking up some material on a plagiarism case and I casually riffled through the catalogs as I am wont to do. I found a very interesting dissertation from the University of Zürich in Switzerland:
Völger, Marion: Wissenschaftsbetrug - Strafrechtliche Aspekte - unter besonderer Berücksichtigung des Missbrauchs staatlicher Forschungsförderung. Schulthess, 2004. ISBN: 3725548129
The dissertation is quite interesting, even for non-lawyers. The author first gives a good overview of definitions for scientific misconduct and an analysis of how scientific enquiry works in the first place. She uses a number of cases that have come to light in recent years to illustrate her points.
Then she goes into the legal aspects: University law, criminal law, all sorts of other legal bits and pieces. She focuses, of course, on Swiss law and explains the complicated system of research financing in Switzerland.
She basically comes to the conclusion that there is not much that one can do, although certain aspects of scientific misconduct could be covered by certain laws. There is a nice summary (in German) at http://archiv.ethlife.ethz.ch/articles/campuslife/betrugundrecht.html.
