Final answer:
When regulations like 40-501 and 40-502 are in conflict, precedence is not based solely on the regulation number. Factors such as the date of issuance, specificity, and authoritative clarifications play a role in determining which regulation should be followed.
Step-by-step explanation:
When resolving conflicts between regulations, it is essential to consider the hierarchy of authority or specificity of the regulations in question. Regulations like 40-501 and 40-502 likely refer to a set of rules within a particular department or code, such as military regulations or departmental policies. If guidance in 40-501 and 40-502 conflict, typically the higher-numbered regulation does not automatically take precedence. Instead, one must consider factors such as the date of issuance, with newer regulations often superseding older ones, or specific clauses which state that one regulation overrides another in case of conflict.
Additionally, the scope and subject matter of the regulations can affect which one takes precedence; more specific regulations often trump more general ones. When in doubt, consult the issuing authority or an updated codification of the regulations that might offer clarification on the precedence.
