4.2 Reasons for Growth of Delegated Legislation

Parliament's limits: time and expertise — the legislature cannot debate every standard and fee; Technicality: the specialized detail (banking, environment, telecom) requiring expert drafting; Flexibility: the quick amendment — the rule changed in weeks, the act in years; Experimentation: the trial regulation, the pilot scheme, the reversible rule; Emergencies: the crisis powers needing immediate operational instruments; The welfare state's breadth: the service-and-regulation state's detail cannot be legislated clause by clause. The other side (the concern that shapes Unit 4.3–4.4): law-making's transfer to the unelected; the accountability's dilution; the public's inability to know the rules that bind it.
