SBVR makes a 'light world' [1] assumption about rules. In a light world, anything that is not expressly prohibited is assumed permitted, and anything not expressly declared as impossible is assumed possible. Business rule practice indicates that this choice is the appropriate one for the large majority of business problems.

Occasionally, practitioners may discover 'dark areas in a light world' — areas in which the opposite assumption is appropriate. In such a dark area, anything not expressly permitted is assumed prohibited, or anything not expressly declared as possible is assumed impossible. Dark areas of the former kind — the more important and common of the two cases — might involve use of, and/or access to, resources that are deemed especially sensitive, dangerous, scarce, and/or valuable. For that reason, it makes sense to grant permission for use and/or access explicitly. Such permissions are often called 'authorizations'.

In everyday business language, an authorization is generally understood to mean a sanction or a warrant [Merriam-Webster Unabridged Dictionary (MWUD)].

[MWUD "sanction" noun]: 6a. explicit permission or recognition by one in authority that gives validity to the act of another person or body

[MWUD "warrant" noun]: 2a. a commission or document giving authority to do something : an act, instrument, or obligation by which one person authorizes another to do something which he has not otherwise a right to do and thus secures him from loss or damage

For SBVR, it is important to note that an authorization is explicit (from "sanction"), and that without it, there is not otherwise a right to do something (from "warrant").
