If First Sale rights, or
a similar legal doctrine, is recognised in case law or statute as covering ebook sales, there could be interesting consequences, particularly if DRM is also challenged on similar grounds.
In the United Kingdom and the United States, where
similar (but not identical)
doctrines of
legal professional privilege exist, and in civil law jurisdictions that do not recognise the concept of privilege but rely heavily on the
doctrine of professional secrecy, significant pressure points arise as a company seeks to keep material privileged and confidential while also satisfying the appetite of public bodies (regulators, prosecutors and legislators) and customer or investor groups for unguarded candour.
