[threepeo]

Concession is a term rather used for tenements to determine their tenure in lease or free hold, as let by their owners for a definite term. Therefore the right is thereby materialized. On the other hand, privilege is used to refer any easement or usufruct to a right of redemption, of access, of trespass or use, facilitation or exploitation of any other immaterial right for a definite or indefinite term, depending on the conditions in which the right occurs.
