A rule's being 'under business jurisdiction' means that it is under the jurisdiction of the semantic community that it governs or guides - that the semantic community can opt to change or discard the rule. Laws of physics may be relevant to a company (or other semantic community); legislation and regulations may be imposed on it; external standards and best Semantics of Business Vocabulary and Business Rules, v1.0 161 practices may be adopted. These things are not business rules from the company's perspective, since it does not have the authority to change them.
