Interim reports[]


We wish to clarify that this initiative has nothing to do with political preferences, personal dirt campaigns or the like. It is our aim to protect the scientific integrity of a doctoral degree in Germany, so that holders of such a degree can continue to be expected to follow good scientific practice. By revealing the existing cases of plagiarism in the dissertation at hand, we were attempting to facilitate the work of the Review panel at the University of Bayreuth that is investigating the matter. Should dissertations of politicians from the other end of the spectrum "distinguish" themselves by way of plagiarism, we would have no problem to proceed in the same manner.
