In modern government, however, these functions are not always completely separated. Administrative authorities may make rules under delegated legislative powers, decide disputes in certain situations and take executive decisions. Understanding the difference between these functions is therefore important in Administrative Law.
The classification helps determine the nature of a governmental power, the procedure to be followed and the legal controls that may apply.
Legislative Function
A legislative function is primarily concerned with making rules of general application.
The legislature exercises the main legislative function by enacting laws. Parliament and State Legislatures create legal rules that apply to persons, activities or situations falling within their scope.
For example, Parliament may enact legislation regulating environmental protection, taxation, consumer protection or public employment.
Main Features of Legislative Function
A legislative act generally:
- Creates or changes legal rules.
- Applies to a class of persons or situations rather than only one individual.
- Is normally prospective in operation.
- Involves policy choices.
- Does not ordinarily depend upon deciding an existing dispute between particular parties.
The legislature does not usually decide whether a particular person has violated a law. That type of determination belongs to administration, tribunals or courts, depending on the statutory framework.
Delegated Legislative Function
Modern legislation frequently gives administrative authorities limited power to make detailed rules.
This is known as delegated legislation.
For example, Parliament may establish a broad regulatory framework through an Act and authorise a statutory authority to make regulations dealing with technical standards or procedural details.
The resulting regulations have a legislative character because they create general rules, even though they are made by an administrative authority rather than directly by Parliament or a State Legislature.
However, delegated legislative power is not unlimited. The authority must remain within the scope of the enabling legislation and the Constitution.
Administrative Function
An administrative function is concerned primarily with implementing and administering the law.
Government departments and public authorities exercise administrative functions when they apply legislation, implement government programmes, regulate activities and make decisions in particular situations.
Examples include:
- Granting a licence
- Issuing a permit
- Collecting taxes
- Implementing a welfare scheme
- Conducting an inspection
- Appointing a public servant
- Taking disciplinary action
- Allocating public resources
Administrative functions may involve considerable discretion because authorities often have to apply general legal rules to different factual situations.
Main Features of Administrative Function
Administrative action generally:
- Implements existing law or policy.
- Is often concerned with particular persons or situations.
- May involve discretion.
- Can have direct consequences for individuals.
- Must remain within the authority granted by law.
For example, a statute may establish the conditions for obtaining a licence, while the relevant administrative authority examines an application and decides whether those conditions have been satisfied.
Judicial Function
A judicial function involves the determination of legal rights, liabilities or disputes through an adjudicatory process.
Courts are the primary institutions exercising judicial functions. Their role includes interpreting and applying law to disputes brought before them.
A judicial decision generally involves:
- A dispute or legal question
- Consideration of applicable law
- Examination of relevant facts or evidence
- Application of law to those facts
- A binding determination
The judiciary is expected to exercise its functions independently and according to law.
Quasi-Judicial Functions
Administrative authorities and tribunals may sometimes perform functions that have a judicial or adjudicatory character.
These are commonly described as quasi-judicial functions.
For example, a statutory tribunal may hear the parties, consider evidence and determine a dispute within its jurisdiction.
The authority may not be an ordinary court, but the decision-making process contains important adjudicatory elements.
This distinction is particularly relevant to Administrative Law because the exercise of quasi-judicial functions may attract procedural safeguards such as natural justice.
Difference Between Legislative, Administrative and Judicial Functions
| Basis | Legislative Function | Administrative Function | Judicial Function |
|---|---|---|---|
| Main purpose | Making legal rules | Implementing and administering law | Deciding legal disputes |
| Nature | Generally general and prospective | Often specific and practical | Adjudicatory |
| Primary institution | Legislature | Executive and administrative authorities | Courts |
| Typical output | Act, rule or regulation | Order, licence, permit or administrative decision | Judgment or decree |
| Policy role | Significant | May involve policy implementation | Limited; primarily applies law |
| Dispute | Usually not dependent on an existing dispute | May or may not involve a dispute | Normally involves a dispute or legal issue |
| Procedure | Legislative procedure | Depends on statute and nature of action | Judicial procedure and principles of fair adjudication |
| Evidence | Not normally determined through adjudication | May be considered depending on the function | Evidence and legal submissions are considered |
| Natural justice | Generally not applied in the same way as adjudicatory proceedings | Depends on the nature and consequences of the action | Fundamental to fair adjudication |
The distinctions are useful but not absolute.
Legislative Function vs Administrative Function
The difference becomes particularly important when an administrative authority is given rule-making power.
A legislative function generally creates a rule of general application.
An administrative function generally applies existing law or policy to a particular situation.
For example:
A regulatory authority making regulations prescribing general safety standards is exercising a legislative-type function.
The same authority inspecting a particular factory and deciding whether it complies with those standards is exercising an administrative function.
The same institution can therefore perform different types of functions.
Administrative Function vs Judicial Function
The distinction between administrative and judicial functions is also not always straightforward.
An administrative authority may have to determine facts, interpret legislation and make decisions affecting individuals without being a court.
The Supreme Court addressed this issue in A.K. Kraipak v. Union of India, where it emphasised that the distinction between administrative and quasi-judicial functions cannot be treated as rigid in every situation.
The development of natural justice has further reduced the importance of relying solely on labels.
Judicial Function vs Quasi-Judicial Function
A court exercises a judicial function as part of the judicial system established under the Constitution and applicable laws.
A quasi-judicial authority, on the other hand, derives its adjudicatory authority from a statute or other legal source.
For example, a tribunal may determine a dispute because legislation gives it jurisdiction over that particular subject.
Both may have to follow principles of fair adjudication, but their constitutional position, jurisdiction and procedural framework may differ.
Why the Distinction Matters
The classification of governmental functions has practical legal significance.
Different Procedures
Different functions may require different procedures.
A legislative authority generally does not conduct a hearing before making every general rule, whereas an adjudicatory authority may have to provide affected parties with an opportunity to be heard.
Natural Justice
The requirements of natural justice depend on the nature of the function and the circumstances.
A decision that seriously affects an individual’s rights or interests may require procedural safeguards even when the authority is formally classified as administrative.
Judicial Review
The manner in which courts review an administrative decision can depend upon the nature of the power being exercised.
Courts generally distinguish between reviewing the legality of administrative action and reconsidering the merits of a policy or administrative choice.
Delegated Legislation
Where an administrative authority makes regulations under delegated legislative power, courts can examine whether the authority has exceeded the authority granted by the parent legislation or violated constitutional requirements.
Blurring of the Three Functions
The traditional separation of legislative, executive and judicial functions is less rigid in the modern administrative State.
An administrative authority may perform all three types of functions at different times.
For example, a regulatory body could:
Make regulations
→ legislative-type function
Grant licences and enforce regulations
→ administrative function
Determine a statutory dispute or impose a regulatory consequence after adjudication
→ quasi-judicial function
This functional overlap is one of the reasons why Administrative Law has become an important field of public law.
Separation of Powers in India
The Indian Constitution does not establish a completely rigid separation of powers.
The three organs have distinct primary functions, but some degree of functional overlap exists.
For example:
- Parliament exercises legislative power.
- The executive administers laws and may exercise delegated rule-making powers.
- Courts interpret the Constitution and laws and exercise judicial power.
- Tribunals and administrative authorities may perform specialised adjudicatory functions where authorised by law.
At the same time, constitutional limitations prevent one institution from exercising power without legal authority.

Important Cases
| Case | Relevance |
|---|---|
| A.K. Kraipak v. Union of India | Demonstrated that the distinction between administrative and quasi-judicial functions cannot always be rigid |
| State of Orissa v. Dr. Binapani Dei | Emphasised fairness in administrative decisions having adverse consequences |
| Province of Bombay v. Khushaldas S. Advani | Discussed the distinction between administrative and quasi-judicial functions |
| Gullapalli Nageswara Rao v. APSRTC | Examined natural justice and administrative decision-making |
| Indian National Congress (I) v. Institute of Social Welfare | Discussed the distinction between administrative and quasi-judicial functions |
A Simple Way to Understand the Three Functions
The distinction can be remembered through the basic question each function answers:
| Function | Basic question |
|---|---|
| Legislative | What should the legal rule be? |
| Administrative | How should the law be implemented? |
| Judicial | What is the legal position in this dispute? |
This is a simplified framework, but it provides a useful starting point for understanding the three functions.
Conclusion
Legislative, administrative and judicial functions represent the three traditional forms of State action. Legislative functions create general legal rules, administrative functions implement and administer those rules, and judicial functions determine legal disputes and interpret the law.
In the modern administrative State, however, these functions frequently overlap. Administrative authorities may make delegated legislation and, where authorised by law, perform quasi-judicial functions. Consequently, the classification of a particular governmental action depends not merely on the name of the authority but on the nature of the power, the purpose for which it is exercised and the legal consequences of the action.
Understanding these distinctions is essential for studying Administrative Law because they help explain why different forms of governmental action are subject to different procedural and legal controls.
