Equality is one of the most important goals provided in the Preamble of the
Indian Constitution, which is an integral part of the Indian Constitution,
established in the case of Kesavananda Bharti v. State of Kerela, 1973
Article 14 of the Indian Constitution provides for 'equality before law', i.e.,
the State shall not deny to any person equality before the law or the equal
protection of the laws within the territory of India Prohibition of
discrimination on grounds of religion, race, caste, sex or place of
birth. However, Article 14 does not purport or mean that every law must have
universal application. Thus, comes the principle of "like should be treated
alike and unlike should be treated differently
The doctrine of reasonable classification also known as the 'Nexus test'
'Doctrine of Nexus'
thus acts as the exception to Article 14. It allows for
distinction to exist between different classes of people, subject to certain
conditions. There are two main conditions that are to be kept in mind when
considering permissible classification: firstly, 'intelligible differentia' and
secondly, 'nexus with an object sought to be achieved.
The former condition
requires that the distinction a law draws between persons or things grouped
together as opposed to others left out of the group must be logical, rational
and not arbitrary in nature. And that there must a real connection which is
direct and not remote between the distinction drawn and the object that is
sought to be achieved by the law drawing the distinction concerned.
For example: Under Section 11 of the Indian Contract Act, 1872, a minor does not
have the capacity to enter into a contract. This requirement provided by Section
11 classifies persons into two categories, i.e., adults and minors. The basis of
the classification is age. Thus, for the law to not be violative of Article 14
it has to have a permissible classification based on age which in this case is
present as age has a relation to the object of the legislation, i.e., capacity
to enter into a contract.
The debate on doctrine of reasonable classification dates back to 1950. This
principle has been reaffirmed and used in various cases and at various levels of
the judicial discourse. The first case that the honourable Supreme Court decided
in reference to doctrine of reasonable classification was of Chiranjit Lal
Chowdhuri v. Union of India (1950)
. The question that the court considered in
this case was whether a manufacturing company could be singled out for adverse
treatment. The Supreme Court in this case held that firstly, a single person
or entity can form a class and secondly, that the onus to establish facts or
circumstances to support the charge of unreasonableness is on the person who
assails the legislation.
This was followed by a landmark case, State of West Bengal v. Anwar Ali Sarkar
The issue at hand in this case was whether the West Bengal Special Courts Act
was unconstitutional by virtue of being violative of Article 14. The Supreme
Court held that the act was indeed unconstitutional as it violated the
principles of Article 14 of the Indian Constitution. According to the court's
reasoning, the law concerned was arbitrary as the act neither laid down any
policies or guidelines for the exercise of discretion to classify the cases or
offences nor a procedure to be followed for trial of such offences.
This was followed by another landmark case of Kathi Raning Rawat v. State of
. The issue in this case was similar to the one above as the
question of law was on the impugned ordinance amendments in the Saurashtra State
Public Safety Measures Ordinance that were made to maintain public order and
preservation of peace of tranquillity.
The appellant claimed that there was
discriminatory classification of offences and the special treatment of such
offences in special courts. The issue thus was whether the said Act was violative of Article 14 and hence, unconstitutional. The Supreme Court in this
case ruled that the Act was not violative of Article 14 and thus,
constitutional. It gave the reasoning that the State Government did not refer
individual cases but offences of certain kind in certain areas, thus there is
legislative differentiation and not discriminatory.
Along with which , the act
was supported by presumption of constitutionality. The said Act was compared by
the West Bengal Special Courts Act and it was observed that it didn't have
Two decades later the Supreme Court in the case of E.P. Royappa v. State of
 held that essence of the rule of equality lies in the
anti-arbitrariness. Justice Bhagwati stated that "Equality is a dynamic concept
with many aspects and it cannot be 'cribbed, cabined and confined' within the
traditional and doctrinaire limits. From the positivistic point of view equality
is antithetic to arbitrariness. In fact, equality and arbitrariness are sworn
enemies.... Where an act is arbitrary, it is implicit in it that it is unequal
both according to political logic and constitutional law and is therefore
violative of Article 14...."
Subsequent to this, in the case of Ajay Hasia v. Khalid Mujid Sehravardi
same was reiterated and it was pointed out that reasonable classification was
not a paraphrase of equality and that it was only one of the means whereby a
judge could decide whether there was an element of arbitrariness or not.
Post this, there were cases that discussed the doctrine of reasonable
classification in different contexts. In the case of Air India v. Nergesh
Meerza the Supreme Court invalidated a regulation which proceeded that an
air hostess would lose her job on her first pregnancy amongst other conditions.
This was invalidated by the Supreme Court for being arbitrary and violative of
In the case of Madhu Limaye v. Supt, Tihar Jail, Delhi
, there was an issue
that the Indian and European prisoners were treated differently. The court held
that this differentiation violated Article 14 of Indian prisoners. They were all
prisoners and thus, must be treated equally.
In 1983, in the case of D.S. Nakara v. Union of India
 the court dealt with
an office memorandum issued by the government announcing a liberalised pension
scheme for retired government servants but made it applicable to those who had
retired after 31 March 1979. The court held that the fixing of cut-off date was
discriminatory as violating Article 14. This was because the division was based
on date of retirement which was not a rational principle and thus, arbitrary.
In the case of A.L. Kalra v. P& P Corporation of India Ltd
, Mr. Kalra was
removed from his job, his only fault was he had taken some loan from the
Corporation for certain purposes which he failed to utilise properly. The
Supreme Court intervened under Article 14 on the ground that the punishment
inflicted on Mr. Kalra was highly disproportionate, harsh and arbitrary.
According to the court's reasoning the action was arbitrary and was denied by
In the case of Central Inland Water Transport Corpn. v. Brojo Nath
 the Supreme Court invalidated a rule of the Corporation which authorised the Corporation to terminate services of any person in the employment
by giving three months' notice or three months' salary in lieu of notice. The
court held that the differentiation was invalid as it influenced the gravity of
consequences that the rule entailed, i.e., a person could lose his/her
In the case of Sanaboina Satyanarayan v. Govt. of A.P
. the issue was whether
the scheme formulated by the State government for prevention of crime against
women violative of A. 14. According to the scheme, in prisons and prisoners were
classified into two major categories: firstly, those guilty of crime against
women and secondly, those not guilty of crimes against women. The prisoners
claimed their right to equality was being violated by this scheme. But the Court
held that there is reasonable classification because there is an objective that
is being achieved by the said scheme and hence, it was not violative of A. 14.
This was followed by the case of Saurabh Chaudhari (Dr.) v. Union of
 the Supreme Court held that the classification must be found on
intelligible differentia and the classification must have a rational relation to
the object sought to be achieved. These two conditions are distinct of each
other, the important fact is that there must be relation between the basis of
classification and the object. When there is no reasonable basis for the
classification then the legislation in question would be discriminatory and
The Supreme Court In Several Cases Established Important Principles Regarding
The Scope Of Permissible Classification:
- A law may be constitutional even though it relates to a single
individual if, on account of some special circumstances, or reasons
applicable to him and not applicable to others, that single individual may
be treated as a class by himself. But such laws are seen with suspicion,
especially when they affect private rights of an individual.
- There is always presumption in favour of constitutionality of an enactment
and the burden is upon him who attacks it to show that there has been a clear
transgression of the constitutional principles. The person, therefore who pleads
that A. 14 has been violated, must make out that not only he has been treated
differently from other, but he has also been treated differently from persons
similarly circumstanced without reasonable basis and such differential treatment
has been unjustifiably made.
- It must be presumed that the legislature understands and correctly
appreciates the need of its own people, that its laws are directed to
problems made manifest by experience and that its differential treatment is
based on adequate grounds.
- The legislature is free to recognise the degrees of harm and may confine
its restriction to those cases where the need is deemed to be the clearest.
- In order to sustain the presumption of constitutionality, the court may
take into consideration matters of common knowledge, matters of common
report, the history of the times and may assume every state of facts which
can be conceives existing at the time of the legislation.
- While good faith and knowledge of the existing conditions on the part of
the legislature are to be presumed, the presumption of constitutionality
cannot be carried to the extent of always holding that there must be some
undisclosed and unknown reasons for subjecting certain individuals or
corporations to hostile or discriminatory legislation.
- A classification need not be scientifically perfect or logically
- The validity of a rule has to be judged by assessing its overall effect
and not by picking up exceptional cases. What the court has to see is
'whether after taking all aspects into consideration, the classification is
- The court must look beyond the ostensible classification and to the
purpose of the law and apply the test of "palpable arbitrariness" in the
context of the felt needs of the times and societal exigencies informed by
experience to determine reasonableness of classification.
- There is not right to equality in illegal acts. Discrimination cannot be
alleged n the ground that somebody has obtained an illegal benefit or
advantage which he could not avail of.
- The right to equality is available in the grant of favours as well as the
imposition of burdens.
Recently the discussion on A. 14 came up when the Citizenship Amendment Act,
2019 came up. The main issue was that the three distinctions made: firstly
between Muslims and non-Muslims of Afghanistan, Bangladesh and Pakistan,
secondly, migrants from these three countries and the other countries and
lastly, between the migrants migrating due to religious persecution and due to
other reasons – were arbitrary and did not qualify as reasonable
In conclusion, the discourse on Article 14's exception of reasonable
classification has a long history and the discussions continue till date. But
there now exist a set of basic principles that have ruled on by the Supreme
Court which must be taken into consideration when determining the validity of a
classification with regard to Article 14.
