In regulatory language, the term "shall" signifies mandatory compliance. This means that whatever follows the word "shall" is a requirement that must be followed, leaving no room for discretion or personal interpretation. Regulatory documents use this term to clearly indicate that adherence to the specified rules or guidelines is obligatory for those subject to the regulation. This establishes an enforceable standard that must be adhered to, contrasting sharply with terms like "should," which suggests recommendations or guidelines rather than requirements. Understanding this distinction is crucial for interpreting regulations accurately and ensures that individuals and organizations know their legal obligations.
