Sources of Laws Handwritten Notes Overview
The Sources of Laws handwritten notes explain how legal rules originate and become binding. Students can revise the three major sources first, then move to valid custom tests, precedent rules and legislation types.
- Best starting point: remember custom, judicial precedent and legislation.
- Scoring area: difference questions on ratio and obiter, custom and legislation, supreme and subordinate legislation.
- Long-answer route: define the source, explain features, then add one Indian example.
Custom as a Source of Law
Custom means a long established practice or unwritten rule that has acquired binding character. Courts recognise only valid customs, so students must revise the tests carefully.

| Test for valid custom | Plain meaning | Exam cue |
|---|---|---|
| Antiquity | The custom should be old and practised from time immemorial. | India has no fixed year like England. |
| Continuity | The custom should be followed without serious interruption. | Broken practice weakens validity. |
| Right and reason | The custom should be open, reasonable and enjoyed as a right. | Secret or doubtful practice is not enough. |
| Morality and statute | The custom must not oppose public policy or legislation. | A new statute is preferred in a modern State. |

Judicial Precedent as a Source of Law
Judicial precedent means earlier decisions of superior courts that lower courts must follow. In India, the doctrine works through the hierarchy of courts.
| Court level | Binding effect | Revision cue |
|---|---|---|
| Supreme Court | Binding on all courts in India. | Apex court of the judicial hierarchy. |
| High Court | Binding on subordinate courts within its jurisdiction. | Other High Courts get persuasive value. |
| Lower Courts | Bound by higher courts in the same state. | Follow their own High Court first. |
Ratio Decidendi and Obiter Dicta
Ratio decidendi is the binding reason for the decision. Obiter dicta are general observations said by the way and usually carry persuasive value.

| Term | Meaning | Binding value |
|---|---|---|
| Ratio decidendi | Reason for the decision drawn from facts and law. | Binding in later similar cases. |
| Obiter dicta | General observation not necessary for the decision. | Persuasive, especially from higher courts. |
| Precedent | Earlier decision used as authority. | Depends on court hierarchy. |
Legislation as a Source of Law
Legislation is the making of law. It is the most important modern source because it is directly enacted and recognised by the State.
| Type | Meaning | Example cue |
|---|---|---|
| Supreme legislation | Law directly enacted by the sovereign authority. | Laws passed by Indian Parliament. |
| Subordinate legislation | Law made by an authority below the sovereign. | Rules, bye-laws and delegated legislation. |
| Delegated legislation | Rule-making power given to executive organs. | Necessary evil due to time, technicality and emergency. |
Important Differences for Exam Revision
Most exercise questions ask students to compare source terms. Write the basis of difference first, then add one example.
- Custom vs legislation: custom grows from long social practice, while legislation is enacted by an authorised law-making body.
- Ratio vs obiter: ratio is the binding reason of decision, while obiter is a persuasive observation.
- Supreme vs subordinate legislation: supreme legislation is made directly by sovereign authority, while subordinate legislation depends on delegated authority.
- Supreme Court vs High Court judgment: Supreme Court decisions bind all Indian courts, while High Court decisions bind courts within that jurisdiction.
