 One might attempt to resolve the first difficulty concerning the agent’s interest by arguing that compliance with official obligation is in the individual’s interest because she desires to maintain her employment. But this explanation rests on an incentive argument. The sanction of dismissal induces the compliance rather than normative motivation to comply with one’s obligation; it is another prudential account. The prudential account of authority thus fails to overcome this first difficulty. It is not clear then that the prudential account of authority can ground the normativity of law.
