Principles of Constitutional Interpretation

Constitutional interpretation involves the methods and principles used by courts to understand and apply the Constitution. The interpretation process is crucial to maintaining the rule of law and ensuring that the Constitution adapts to changing societal values and conditions.
What are the Principles of Constitutional Interpretation?
The principles of constitutional interpretation guide courts in understanding and applying the Constitution. These principles ensure that the Constitution remains relevant and adaptable to changing societal needs. Key principles include:
- Literal Interpretation: Focusing on the plain meaning of the text.
- Harmonious Construction: Ensuring that different provisions of the Constitution do not conflict and are interpreted in a way that all can coexist.
- Doctrine of Pith and Substance: Determining the true nature of legislation to ascertain its constitutional validity.
- Doctrine of Colourable Legislation: Preventing legislatures from doing indirectly what they cannot do directly under the Constitution.
- Doctrine of Severability: Allowing parts of a law that are unconstitutional to be severed, keeping the rest of the law intact.
Various principles of constitutional interpretation guide this process and the following are some of the most frequently discussed in judicial decisions.
1. Principle of Colourable Legislation
The doctrine of colourable legislation addresses situations where the legislature, within the constraints of the Constitution, attempts to do indirectly what it cannot do directly. This principle of constitutional interpretation is based on the Latin maxim “Quando aliquid prohibetur ex directo, prohibetur et per obliquum,” meaning that what is prohibited directly is also prohibited indirectly.
Key Features:
- Legislative Competence: The principle is primarily concerned with whether a legislature has the authority to enact a particular law.
- No Examination of Motives: It does not involve questions of legislative bona fides or mala fides (good or bad faith).
- Direct vs. Indirect Legislation: The doctrine comes into play when a legislature tries to achieve an objective indirectly that it cannot achieve directly due to constitutional constraints.
- Application in India: This doctrine is often applied concerning Article 246, which delineates the legislative competencies of the Parliament and State Legislative Assemblies through the Union, State and Concurrent Lists in the Seventh Schedule.
In cases where the legislature tries to enact laws under the guise of legitimate objectives while circumventing constitutional limitations, courts use this principle to determine the validity of such laws.
State of Bihar v. Kameshwar Singh, 1952
State of Bihar v. Kameshwar Singh challenged the constitutional validity of the Bihar Land Reforms Act, 1950. The Act stipulated that the rent from the landlord’s land, prior to the state’s acquisition of the holding, would vest with the state. However, half of this rent was to be returned to the landlord as compensation.
The Supreme Court held that this provision amounted to naked confiscation. The act of taking the entire rent and returning only half was essentially the same as taking half without compensation. While the Act purported to lay down principles for compensation, its actual objective was confiscation—a subject falling under the Concurrent List. Consequently, the Court deemed the Bihar Land Reforms Act as colourable legislation, rendering it void.
Naga People’s Movement for Human Rights v. Union of India, 1997
In Naga People’s Movement for Human Rights v. Union of India, the Supreme Court clarified the application of the doctrine of colourable legislation. The doctrine is pertinent only when:
- The true intention behind a legislation is disguised.
- There is an intent to encroach upon the domain of another legislature.
The purpose of a legislation might differ from its apparent objective. However, it does not constitute colourable legislation if the issue does not pertain to the legislative competence to enact it. The doctrine does not consider whether the legislation was enacted with bona fide or mala fide intentions. The only relevant question is whether the substance of the statute falls within the legislative domain of the enacting body.
2. Principle of Pith and Substance
The principle of pith and substance is used to determine the true nature and essential character of a legislation, especially when there is a conflict regarding legislative competencies between the Union and State legislatures.
Key Features:
- True Nature and Substance: “Pith” refers to the true nature or essence of something, while “substance” refers to its most important or essential part.
- Resolution of Conflicts: This doctrine of constitutional interpretation helps resolve conflicts by determining which legislative field (Union List, State List or Concurrent List) a particular piece of legislation falls into.
- Intra Vires vs. Ultra Vires: If the pith and substance of the legislation fall within the legislative competence of the enacting body, it is deemed intra vires (within powers), even if it incidentally encroaches upon matters outside its jurisdiction.
State of Bombay v. FN Balsara
In State of Bombay v. FN Balsara, the Bombay Prohibition Act, 1949, which prohibited the sale and possession of liquor, was challenged for encroaching upon the Union List. The court upheld the act because its pith and substance fell under the State List, despite incidental encroachments on the Union List.
Premchand Jain v. R.K. Chhabra, 1984
In the case of Premchand Jain v. R.K. Chhabra (1984), the Supreme Court reiterated that incidental encroachment does not render an enactment invalid. The Court held that if a law primarily falls within the legislative powers granted by the Constitution to the enacting legislature, it remains valid even if it incidentally encroaches on matters assigned to another legislature.
State of Bombay v. Narottamdas, 1950
In State of Bombay v. Narottamdas (1950), the Supreme Court held that to validate incidental encroachment, it must be shown that the pith and substance of the law lie within the enacting legislature’s domain. The validity of a statute is determined by its true nature, not merely by the degree of encroachment. If the core purpose and essence (pith and substance) of the law fall within the legislative powers of the enacting body, the law is upheld.
Krishna v. State of Madras, 1956
The Madras Prohibition Act, enacted in 1937, faced a challenge over a decade later for prescribing procedures and principles of evidence for trials. The appellants argued that the Act contradicted the central Criminal Procedure Code, 1973. However, the court upheld the Act, stating that it was ancillary to the central legislation. The court concluded that the Act, in its pith and substance, pertained to intoxicating liquors—a matter within the state list.
3. Principle of Eclipse
The doctrine of eclipse states that a law inconsistent with fundamental rights is not entirely invalid but remains inoperative to the extent of the inconsistency. This inconsistency can be removed through constitutional amendments, thereby reviving the law.
Key Features:
- Inoperative vs. Invalid: The law does not become null and void but is overshadowed by the fundamental right.
- Constitutional Amendments: The eclipse can be removed if a constitutional amendment eliminates the inconsistency.
- Pre-Constitution Laws: This principle particularly applies to laws that existed before the commencement of the Constitution and became inoperative due to conflicts with fundamental rights.
Keshavan Madhava Menon v. The State of Bombay
In the landmark case of Keshavan Madhava Menon v. The State of Bombay, the issue revolved around a law that existed before the Indian Constitution came into force. This pre-constitution law imposed restrictions on the right to practice any profession, trade or business, which is guaranteed to citizens of India under Article 19(1)(g).
Key Points of the Case:
- Existing Law: The law in question was already in force when the Constitution was enacted.
- Inconsistency with Fundamental Rights: The restrictions imposed by this law could not be justified as reasonable under clause (6) of Article 19, which allows for reasonable restrictions on the right to practice any profession, trade or business.
- Article 13(1): According to Article 13(1), any pre-constitution law that is inconsistent with the fundamental rights conferred by Part III of the Constitution becomes void to the extent of such inconsistency.
Supreme Court’s Ruling:
The Supreme Court held that the law did not become void in its entirety or for all purposes, times and persons. Instead, it became void only “to the extent of such inconsistency.” This meant that the law remained valid except for the parts that were inconsistent with the fundamental rights enshrined in Part III of the Constitution.
The Court clarified that the law’s invalidity was limited to its conflict with the new constitutional provisions. As a result, the law was not entirely abrogated but was rendered inoperative only to the extent that it infringed upon the fundamental rights of the citizens.
4. Principle of Severability
The doctrine of severability, provided for under Article 13 of the Indian Constitution, states that if parts of a law are unconstitutional, those parts can be severed, leaving the rest of the law intact and enforceable.
Key Features:
- Severable vs. Inseverable: The unconstitutional provisions are severed if the remaining law can still function independently and effectively.
- Constitutional Provisions: This principles of constitutional interpretation states that laws that contravene fundamental rights are void to the extent of inconsistency.
- Preservation of Legislation: Courts strive to preserve as much of the legislation as possible by severing only the unconstitutional parts.
AK Gopalan v. State of Madras
In AK Gopalan v. State of Madras, the Supreme Court said that in case of repugnancy to the Constitution, only the repugnant provision of the impugned Act will be void and not the whole of it and every attempt should be made to save as much as possible of the Act.
If the omission of the invalid part will not change the nature or the structure of the object of the legislature, it is severable. It was held that except Section 14 all other sections of the Preventive Detention Act, 1950 were valid and since Section 14 could be severed from the rest of the Act, the detention of the petitioner was not illegal.
5. Principle of Territorial Nexus
The principle of territorial nexus allows for legislation to have an effect beyond the territorial limits of the enacting body, provided there is a sufficient connection between the subject matter and the territory.
Key Features:
- Extra-Territorial Operation: Article 245(2) clarifies that Parliament’s laws are not invalid due to extra-territorial operation.
- Sufficient Connection: There must be a real and substantial connection between the law and the territory.
- Taxation and Other Laws: Often applied in cases involving taxation where the subject matter is outside the territorial limits but has a significant nexus with the state.
State of Bombay v. RMDC, 1957
In State of Bombay v. RMDC (1957), the legality of a lump sum tax imposed by the Bombay Government on lotteries was challenged. The lottery in question was conducted through a newspaper that had wide circulation within the State of Bombay and outside its boundaries. The tax extended to the circulation and distribution of newspapers that were published outside the state.
The Supreme Court upheld the tax, stating that there was sufficient territorial nexus to justify the imposition of the tax. The critical factor was that the collection of entry fees for the lottery competition took place within Bombay. Despite the newspapers’ wide circulation beyond the state’s borders, the locus of the taxable activity—entry fee collection—was within Bombay. Therefore, the court concluded that the tax was valid due to the substantial and real connection between the activity being taxed and the territory of Bombay.
State of Bombay v. Narayandas Mangilal, 1957
In State of Bombay v. Narayandas Mangilal (1957), the Supreme Court addressed the validity of a law enacted by the Bombay legislature that criminalised bigamous marriages. This law extended to marriages conducted outside Bombay if one of the parties was domiciled in Bombay.
The Supreme Court struck down the law, citing an insufficient territorial nexus. The Court reasoned that the law could not apply to marriages performed outside the state merely because one party was domiciled in Bombay. The connection between the act of marriage outside the state and the domicile of one party within the state was deemed too tenuous to sustain the legislative authority of Bombay over such marriages. Hence, the lack of a substantial and real connection led to the law being invalidated for its overreach beyond territorial jurisdiction.
6. Principle of Implied Powers
The doctrine of implied powers holds that powers not explicitly stated but necessary for the execution of constitutionally granted powers are also valid.
Key Features:
- Necessity and Proper Clause: Powers necessary and proper for executing granted powers are implied.
- Constitutional Interpretation: General terms in constitutional grants of power or restraints lead to implied powers or restraints.
- Execution of Powers: Ensures that the legislative and executive branches can effectively perform their constitutionally assigned duties.
Legal Basis: This principle is rooted in the functional and purposive interpretation of the Constitution, ensuring that the spirit of constitutional provisions is fulfilled even when not explicitly stated.
7. Doctrine of Harmonious Construction
The doctrine of harmonious construction is a judicial principle used to resolve conflicts between different provisions of the same statute. It operates on the presumption that the legislature did not intend for one provision to negate or contradict another and that every provision should be given effect to the fullest extent possible.
Key Principles of Harmonious Construction:
- Avoiding Neglect of Provisions: The legislature does not intend to prioritise one provision over another, nor does it intend to create contradictions.
- Ensuring Coherence: Conflicting provisions should be interpreted in a manner that allows both to coexist without rendering any part ineffective or redundant.
Sultana Begum v. Premchand Jain, 1996
In this case, the Supreme Court elaborated on the doctrine, stating that conflicting provisions should be interpreted to ensure neither is ignored. The court emphasised the need to read the statute as a whole and to construe it in a way that maintains the effectiveness of all its provisions.
Jagdish Singh v. Lt. Governor, Delhi, 1997
Here, the Supreme Court reiterated the need to read statutes harmoniously, ensuring that no provision becomes ineffective. The court emphasised that the objective of harmonious construction is to avoid conflict and promote the smooth functioning of the legislative intent.
Shankari Prasad v. Union of India, 1951
Shankari Prasad v. Union of India addressed the objective of harmonious construction by stating that when two articles of the Constitution are broadly phrased and conflict in their operation, they should be controlled and qualified by each other to maintain harmony.
Ram Krishan v. Vinod, 1951
In this case, the Supreme Court resolved a conflict within the Representation of the People Act, 1951. Section 33 allowed government servants to nominate candidates, while Section 123 prohibited them from assisting candidates except by voting. The Court harmoniously construed these provisions, allowing government servants to nominate and vote for candidates, but prohibiting any other form of assistance.
Bengal Immunity Co. v. State of Bihar, 1955
Bengal Immunity Co v State of Bihar highlighted the limits of the doctrine. The Court held that conflicting provisions should be interpreted to allow both to be effective. However, if it is impossible to harmonise the provisions, the less useful provision can be ignored, provided there is no compulsion to adopt it.
8. Doctrine of Repugnancy
The doctrine of repugnancy addresses conflicts between state and central laws in India. Article 254 of the Indian Constitution provides the framework for resolving such conflicts.
Article 254(1)
Article 254(1) states that if a state law is repugnant (i.e., incompatible) with:
- A law that the Parliament is competent to enact, or
- An existing law under the Concurrent List,
then the central or existing law prevails and the state law is void to the extent of the repugnancy. The chronology of the laws’ enactment is irrelevant.
Key Points:
- Central Law Prevails: In case of conflict, the central law overrides the state law.
- Repugnant Provisions: The conflicting parts of the state law do not become ultra vires (beyond powers); they are merely eclipsed. If the central law is repealed, the state law provisions become operative again.
- Doctrine of Pith and Substance: This doctrine is used to determine if the true nature of the state law falls under a matter listed in the Concurrent List. If the repugnancy is with a central law, it must be assessed whether Parliament intended to create an exhaustive code on the matter. If not, any qualifications or restrictions by the state law are not considered repugnant.
Article 254(2)
Article 254(2) provides an exception where a state law on a concurrent matter, repugnant to a central law, can prevail if it receives Presidential assent. However, this only applies to the state concerned and not uniformly across the country.
Key Points:
- Presidential Assent: The state law can override the central law if it receives Presidential assent, but it must be specified that the assent is sought for the repugnancy with a particular act. Failing to specify this makes the state law invalid.
- State-Specific Application: The inconsistent provisions apply only within the state that enacted the law.
- Subsequent Central Laws: If the central government enacts a new law conflicting with the state act that had Presidential assent, the central law prevails, as held in Pt. Rishikesh v. Salma Begum (1995).
Srinivasa Raghavachar v. State of Karnataka, 1987
The case involved a state law restricting legal practitioners from appearing before land tribunals. The Supreme Court found the state law invalid due to its repugnancy to the Advocates Act, 1961.
Sukumar Mukherjee v. State of West Bengal, 1993
The West Bengal State Health Service Act, 1990, barred state health service members from private practice, conflicting with the Indian Medical Council Act, 1956, which allowed practitioners to practice anywhere in India. The Court upheld the state law, distinguishing it from the Srinivasa Raghavachar case by noting that health service members voluntarily gave up private practice rights.
Kumar Sharma v. State of Karnataka, 1990
This case held that repugnancy must concern a matter in the Concurrent List. If the subject matters of the conflicting laws are different, both can stand together. However, a dissenting opinion argued that irreconcilable conflicts should lead to the state law being struck down.
Variyar Thavathiru Sundara Swamigal Medical Education & Charitable Trust v. State of Tamil Nadu, 1996
This case dealt with a Tamil Nadu statute on the affiliation of medical colleges, challenged for repugnance against the Indian Medical Council Act. The Court held that Parliament intended to lay down an exhaustive code for the subject, making the state act invalid.
Conclusion
These principles of constitutional interpretation play a critical role in maintaining the balance of power between different branches of government, protecting individual rights and ensuring the Constitution remains a living document capable of addressing contemporary issues. By applying these doctrines, courts can interpret the Constitution in a manner that respects its text and underlying principles while adapting to changing societal needs.
