The article examines the legal connection between constitutionalism and Lon Fuller's inner morality of law, contending that both procedural and moral underpinnings support constitutional validity. It demonstrates that constitutionalism gets its authority from the moral duty to preserve natural rights and the procedural integrity of law making, drawing on John Locke's notion of limited government. On the other hand, because it lacks moral support, H.L.A. Hart's notion of "having an obligation" is insufficient to explain constitutional compliance. The study maintains that Locke's philosophical vision is operationalized by Fuller's procedural morality, which together provides the moral framework that upholds constitutional rule beyond simple legal formality.

Inner Morality, Having An Obligation, Constitutionalism.
