Distinguish from sense 1 (NOT STRICT): sense 1 describes a person or organisation's general attitude or approach to rules and standards (e.g., a lax manager, lax enforcement). Sense 2 describes the specific measure, rule, or penalty itself being too weak to be effective (e.g., a lax fine, a lax sentence). The two are complementary but distinct — a person's attitude (sense 1) determines whether the rules they impose are weak (sense 2). Common with nouns: sentence, regulations, measures, controls, fine.
