Jurisprudence, Nature and Sources of Laws

The One Thing

Jurisprudence is the systematic study of the nature, purpose, sources and development of law. In India, law regulates society through a constitutional framework that combines legislation, judicial decisions, customs, personal laws and legal reasoning while seeking to protect rights, maintain order and promote justice.

Who and What

• Jurisprudence: The study of the nature, purpose, concepts, principles and development of law. It examines what law is, why it exists and how it relates to society.
• Law: A binding rule or system of rules recognised and enforced by a competent authority or the state. Its functions include regulating conduct, protecting rights, maintaining order, settling disputes, preventing harm, promoting justice and supporting social change.
• Rule of Law: The principle that everyone, including government authorities, is subject to the law and entitled to equal legal protection. It requires equality before law, freedom from arbitrary government action, independent courts and effective legal remedies.
• Natural Law: The theory that law is based on universal principles of morality, reason, justice and human nature.
• Positive Law: Law created, recognised or enforced by a duly authorised human authority, such as Parliament or a court.
• Civil Law: Law dealing mainly with disputes between individuals or organisations, including contract, property and family disputes.
• Criminal Law: Law dealing with offences against society or the state and prescribing punishments for those offences.
• Substantive Law: Law defining rights, duties, liabilities and offences.
• Procedural Law: Law establishing the methods and processes for enforcing rights, investigating offences and conducting cases.
• Public Law: Law concerning relationships between individuals and the state, and the organisation and functioning of government.
• Private Law: Law regulating relationships and disputes between private persons or organisations.
• Constitution: The supreme law of India. It establishes government institutions, distributes powers and protects fundamental rights. The Constitution of India was adopted on 26 November 1949 and came into force on 26 January 1950.
• Legislation: Law made by a competent legislature, such as Parliament or a State Legislature. Parliament and State Legislatures make laws within the subjects and limits prescribed by the Constitution.
• Delegated Legislation: Rules, regulations, orders or notifications made by an executive authority under powers granted by a legislature.
• Judicial Precedent: A legal principle established in an earlier court decision that may guide or bind courts in later similar cases.
• Stare Decisis: The principle that courts should follow established legal decisions to maintain consistency and certainty.
• Custom: A long-established and generally accepted practice that may become legally recognised if it is certain, reasonable and not opposed to law or public policy.
• Personal Law: Rules governing marriage, divorce, inheritance and adoption for particular religious or customary communities, subject to constitutional and statutory limits.
• Legal Right: An interest or claim recognised and protected by law.
• Legal Duty: An obligation imposed or recognised by law, breach of which may lead to a legal consequence.
• Sanction: A legal consequence or penalty used to encourage compliance with law, such as imprisonment, a fine or compensation.
• Justice: Fair treatment and the proper protection of rights, including legal, social, economic and political fairness.
• Sources of Indian law: The main formal sources are the Constitution, legislation, judicial precedents, customs, personal laws and delegated legislation.
• Supreme Court: The highest court in India. Under Article 141 of the Constitution, its decisions are binding on all courts in India.
• Judicial review: The power of courts to examine whether laws and executive actions are consistent with the Constitution.
• Separation of powers: The distribution of law-making, law-enforcing and law-interpreting functions among the legislature, executive and judiciary, with constitutional checks intended to prevent misuse of power.

Causes and Consequences

• Because the Constitution of India is the highest source of law, all other laws must conform to it. Consequently, legislation violating constitutional provisions may be declared invalid by the courts.
• Because Parliament and State Legislatures possess law-making authority only within the subjects and limits prescribed by the Constitution, legislative power is constitutionally controlled rather than unlimited.
• Because judicial review permits courts to assess laws and executive actions against the Constitution, it protects constitutional supremacy and limits arbitrary government action.
• Because the Supreme Court’s decisions are binding on all courts under Article 141, judicial precedents promote consistency and certainty throughout the legal system.
• Because stare decisis requires courts to follow established decisions, similar cases are generally treated alike. However, courts may distinguish earlier cases or overrule decisions when legal principles or circumstances require change.
• Because customs develop through long-established social practice, they can become sources of law only when they are ancient or long-established, certain, continuous, peaceful, reasonable, obligatory and not opposed to statute, morality or public policy.
• Because personal laws regulate matters such as marriage, divorce, inheritance and adoption for particular religious or customary communities, their operation remains subject to constitutional and statutory limits.
• Because law is both a means of social control and an instrument of social reform, it can maintain order while also protecting vulnerable groups and responding to changing social conditions.
• Because rights create corresponding duties, breach of a legal duty may lead to a legal remedy or sanction. This relationship can be expressed as: rights create corresponding duties, and breach of a legal duty may lead to a legal remedy or sanction.
• Because law must balance individual freedom, social welfare, equality and justice, its validity involves more than moral approval. Law must also be recognised by a competent authority and conform to the Constitution.
• Because morality and law may overlap, they are not identical: every immoral act is not necessarily illegal, and every legal rule is not simply a moral rule.
• Because an effective legal system requires accessibility and fairness, a law should ideally be clear, publicly known, prospective, fairly applied and enforceable.
• Because legal rules operate in different contexts, law may be classified as civil or criminal, public or private, substantive or procedural, and national or international.

What Gets Asked

• Explain the meaning and scope of jurisprudence, and distinguish between natural law and positive law.
• Compare civil and criminal law, public and private law, and substantive and procedural law.
• Explain why the Constitution of India is the highest source of law, including its adoption on 26 November 1949, commencement on 26 January 1950, and role in controlling legislation.
• Discuss the principal sources of Indian law: the Constitution, legislation, delegated legislation, judicial precedents, customs and personal laws.
• Evaluate the importance of judicial precedent and stare decisis, including the circumstances in which courts may distinguish or overrule earlier decisions.
• Explain the rule of law, separation of powers, judicial review, legal rights, legal duties and sanctions, and assess how law balances social control with social reform.
