Some nationalizations take place when a government seizes property acquired illegally.

The kind of information acquired illegally included private communication, physical location of individuals, bank account records, medical records, phone bills, tax files, and organisational strategies.

Many museums will not accession objects that have been acquired illegally or where other parties have an interest in the object.

When loads of wood were found to have been acquired illegally, the agents confiscated it and auctioned it off to the public, and later, in foreign markets.
