There may be circumstances where academic degrees or the title of professor are obtained deceitfully, i.e. in breach of copyrights or moral principles in science. Dishonesty in scientific research constitutes gross misconduct because it is executed in order to appropriate ideas, findings, collocations and theses of others, without accurate citation of the source. It also entails infringement of intellectual property rights. Scientific misconduct in ethical and legal aspect is explicit. It disqualifies the offender as a scientist. The unlawful act of obtaining an academic degree (Ph.D.) or the title of professor in such a deceitful manner, irrespective of how much time has passed, shall not make the resumption condition fall under the statute of limitations. Thus, it enables the reopening of procedures to deprive the person who deceitfully obtained an academic degree or title of this degree or title.
