Doctrine of Precedent; Distinguish between authoritative and persuasive judicial decision.

The Doctrine of Precedent (also known as Stare Decisis) is a fundamental principle of legal systems based on Common Law. It dictates that the legal reasons given by a higher court in a previous case are binding on lower courts in subsequent cases with similar facts.

Essentially, it ensures that the law is consistent, predictable, and certain.

1. The Doctrine of Precedent

The doctrine is based on the maxim "Stare decisis et non quieta movere," which means "to stand by things decided and not disturb settled points."

When a judge decides a case, they do not just resolve the dispute between the parties; they also declare a legal principle. This principle is called the Ratio Decidendi (the reason for the decision). In future cases, judges are required to follow this principle to ensure that similar situations are treated alike by the law.

2. Distinguishing Authoritative and Persuasive Decisions

Not every judicial decision carries the same weight. Jurisprudence distinguishes between them based on their level of "command."

Authoritative Precedents

An authoritative precedent is one which judges must follow, whether they personally agree with the reasoning or not. The judge has no legal choice but to apply the rule.

• Source: Usually comes from a court higher in the same hierarchy (e.g., the Supreme Court’s decision is authoritative for all High Courts in India under Article 141).

• Legal Force: It is a direct source of law.

• Nature: It is mandatory and binding.

Persuasive Precedents

A persuasive precedent is one which the court is not bound to follow but which it will take into consideration and attach great weight to. It "persuades" the judge but does not "command" them.

• Source: Decisions from courts of other jurisdictions (e.g., a Delhi High Court judge looking at a Bombay High Court ruling) or decisions from foreign courts (e.g., citing a UK Supreme Court case in an Indian court).

• Legal Force: It is an indirect or historical source of law.

• Nature: It is optional. A judge may adopt it if they find the reasoning sound and logical.

3. Comparison Table

Feature	Authoritative Precedent	Persuasive Precedent
Obligation	Legally binding; must be followed.	Not binding; may be followed.
Source	Higher court in the same hierarchy.	Parallel courts, lower courts, or foreign courts.
Judge's Role	The judge must apply the rule mechanically.	The judge evaluates the logic of the rule.
Example	Supreme Court ruling applied by a District Court.	US Supreme Court ruling cited in an Indian High Court.

4. Absolute vs. Conditional Authority

Within authoritative precedents, there is a further sub-division:

• Absolutely Authoritative: These cannot be disregarded under any circumstances (e.g., a Full Bench decision of the Supreme Court).

• Conditionally Authoritative: These are usually binding but can be disregarded if they are found to be per incuriam (decided in ignorance of a statute or a higher binding precedent) or if they are outdated.

The doctrine of precedent balances the need for stability (by following authoritative rulings) with the need for growth (by allowing persuasive rulings to introduce new legal ideas).
