Scholars have raised very serious doubts about the provenance of the papyrus discussed in a presentation at the 2015 Annual Meeting. These doubts are so serious that the publisher Brill has recently published a retraction notice of a chapter that includes material from this talk. The SCS is not in a position to issue a judgment about this particular case, but the Society wishes to stress that academic honesty is of the utmost importance in all talks and publications, and that in 2015 our guidelines on professional ethics said "Members of the profession should abide by the 1970 UNESCO convention on the means of prohibiting and preventing the illicit import, export and transfer of ownership of cultural property." The Society’s Statement on Professional Ethics has been further revised since then in order to provide more detailed guidance on the ethical and legal treatment of cultural property.
