CB.13:10 - Rationale
A shared decision needs more than discussion: it needs a rule that gives a result force for the specified participants and subject. That rule itself must be established through a valid basis. Starting from the actual common work exposes both the needed mandate and the questions that can remain elsewhere.
Testing ordinary and disputed use reveals omissions that an organisation diagram hides. Making adoption, appointment and provision distinct prevents a selected arrangement from being mistaken for an operating one. Bounded amendment and expiry then allow useful continuity without silently enlarging the original authority.
