Past Practice vs. Legal Requirement Conflict in Employment Law

1. Introduction

A past practice versus legal requirement conflict arises when an employer continues a workplace practice because it has been followed for years, even though that practice conflicts with a statute, binding regulation, applicable service rule, collective agreement, or judicially established legal principle.

In Indian employment law, an employer cannot automatically justify an unlawful practice by arguing that it has existed for a long time, that employees previously accepted it, or that management has consistently followed it.

For example, an organisation may have historically paid overtime only to employees who obtained prior written approval. If applicable law requires overtime compensation for qualifying work actually performed, the employer cannot necessarily avoid payment merely because the employee did not follow the internal approval procedure.

The central legal principle is that established workplace practice may be relevant to interpreting employment rights, but it cannot ordinarily override a mandatory legal requirement.

This issue is especially important in:

Employment contracts, standing orders and service rules.

Wages, overtime, leave, bonuses and gratuity.

Disciplinary action and termination.

Promotions, seniority and regularisation.

Equal treatment and non-discrimination.

Collective bargaining and industrial relations.

HR policies, payroll systems and long-standing managerial customs.

This explanation focuses primarily on Indian employment law, including industrial and public-service employment principles. The precise result depends on the applicable statute, the employment category, the relevant dates and the facts of the dispute.

2. What constitutes past practice?

Past practice is a pattern of conduct repeatedly followed by an employer, employee group, management team or organisation over a period of time.

Examples include:

Paying a particular allowance even though the written policy is silent.

Allowing employees to leave early on a particular day.

Promoting employees according to an unwritten seniority convention.

Tolerating a specific category of misconduct without formal discipline.

Paying overtime or incentives through an established formula.

Allowing managers to approve leave informally.

Following a customary procedure for employee transfers or termination.

Not every repeated practice becomes an enforceable legal entitlement. Its legal significance depends on the source of the practice, its consistency, the parties' conduct, contractual incorporation, statutory provisions and whether the practice is lawful.

Types of past practice

3. Legal principles governing conflicts between past practice and law

A. Statutory law prevails over inconsistent workplace custom

Where legislation imposes a mandatory obligation, an employer cannot ordinarily avoid it by relying on a contrary custom, internal policy or established practice.

For example, if a law requires payment of a particular statutory benefit to eligible employees, the employer cannot lawfully discontinue it merely because its payroll department has historically omitted that payment.

The first question is whether the alleged requirement is genuinely mandatory and applies to the employee concerned. Not every statutory provision is absolute, and some laws permit specified exceptions or alternative arrangements.

B. Statutory service rules prevail over inconsistent administrative instructions

In public employment, executive instructions and informal departmental conventions generally cannot replace or contradict binding statutory service rules. Administrative instructions may fill gaps or supplement the rules where legally permissible.

A department therefore cannot justify an unlawful recruitment, promotion or seniority decision merely by saying that the same method was used for earlier employees.

C. Past practice may create evidence of an employment entitlement

A consistent and established practice can be relevant when determining:

Whether an allowance or benefit forms part of the employment bargain.

How an ambiguous contractual term should be interpreted.

Whether a settlement or award has been implemented consistently.

Whether an employer has acted arbitrarily or discriminatorily.

Whether employees had reasonable grounds to rely on a particular procedure.

However, evidence of a past practice does not automatically establish a binding contractual term or an enforceable legal right.

D. Equality does not require the repetition of an unlawful act

An employee cannot necessarily demand the same unlawful benefit merely because another employee received it earlier.

For example, if several employees were promoted without satisfying mandatory eligibility requirements, those earlier promotions do not automatically entitle another employee to the same treatment. At the same time, the employer must still comply with applicable equality, non-arbitrariness and procedural-fairness requirements.

E. A lawful change in practice must still comply with applicable protections

An employer may have the legal authority to revise a policy prospectively. However, the change may be restricted by contractual terms, statutory requirements, certified standing orders, collective settlements, established legal rights or applicable requirements for consultation and notice.

The employer should distinguish between changing a discretionary practice and withdrawing an existing legal entitlement.

4. Eight important Indian case laws

The following decisions establish principles relevant to conflicts between workplace practices, administrative conventions, contractual arrangements and binding legal requirements. They do not all concern an identical factual dispute; their relevance depends on the legal issue involved.

Case 1: Sant Ram Sharma v. State of Rajasthan

Citation: AIR 1967 SC 1910; (1968) 1 SCR 111.

Facts and issue: The dispute concerned the relationship between statutory service rules and executive instructions relating to service conditions and promotion.

Legal principle: Executive instructions can supplement statutory rules where the rules leave a gap, but they cannot amend, supplant or contradict binding statutory rules.

Application to past practice: A government department cannot defend a promotion procedure that violates applicable service rules by arguing that the same procedure was routinely followed in earlier years. An established administrative convention cannot displace a mandatory legal qualification or selection requirement.

Practical significance: HR and public-sector management should distinguish between a lawful administrative procedure and an informal practice that conflicts with binding service rules.

Case 2: B.N. Nagarajan v. State of Mysore

Citation: AIR 1966 SC 1942; (1966) 3 SCR 682.

Facts and issue: The Supreme Court considered the relationship between statutory recruitment rules and the government's executive power in regulating public appointments.

Legal principle: Executive power may be exercised in areas not governed by statutory rules, subject to the Constitution and applicable law. It cannot be used to disregard binding rules.

Application to past practice: An organisation cannot justify a departure from mandatory recruitment requirements simply because a different method has traditionally been used. Conversely, where the law leaves a genuine gap, a lawful administrative instruction may regulate the matter.

Practical significance: Before treating a long-standing procedure as legally binding, an employer should determine whether the procedure is authorised by legislation, rules or a valid exercise of administrative power.

Case 3: Secretary, State of Karnataka v. Umadevi (3)

Citation: (2006) 4 SCC 1.

Facts and issue: The case concerned temporary, casual and daily-wage employees who sought regularisation of their employment after prolonged service.

Legal principle: Public employment must comply with the constitutional scheme and applicable recruitment requirements. Long service or continued engagement alone does not ordinarily create a right to permanent appointment where the original engagement violated the governing recruitment framework.

Application to past practice: A government department cannot justify bypassing regular recruitment indefinitely by arguing that it has employed people through the same temporary arrangement for many years.

Important qualification: The judgment recognised a limited one-time consideration for certain irregular appointments meeting specified conditions. Later case law has also clarified that Umadevi should not be applied mechanically to every industrial adjudication or statutory unfair-labour-practice dispute.

Practical significance: Repeatedly engaging temporary workers is not a substitute for lawful recruitment. Employers must assess the legality of the underlying arrangement rather than relying solely on its duration.

Case 4: Western India Match Co. Ltd. v. Workmen

Citation: (1973) 4 SCC 555.

Facts and issue: The dispute concerned the relationship between certified standing orders and inconsistent terms or arrangements governing employment.

Legal principle: Certified standing orders have statutory force in governing the matters they cover. An inconsistent contractual arrangement cannot simply displace the applicable standing orders.

Application to past practice: If an employer has informally followed a disciplinary procedure that conflicts with binding standing orders, the employer cannot automatically rely on that informal practice instead of complying with the applicable standing orders.

Practical significance: HR teams should review certified standing orders before relying on customary procedures for misconduct, attendance, termination or other matters covered by them.

Case 5: State of Punjab v. Jagjit Singh

Citation: (2017) 1 SCC 148; AIR 2016 SC 5176.

Facts and issue: The case involved temporary employees claiming wages equivalent to those paid to regular employees performing comparable work.

Legal principle: The Supreme Court recognised the application of the principle of equal pay for equal work to qualifying temporary employees performing work comparable to that of regular employees, subject to the legal test and relevant differences in duties, responsibilities and qualifications.

Application to past practice: An employer's historical practice of paying temporary workers less is not, by itself, sufficient to establish that the pay differential is lawful. The employer must assess whether the relevant legal requirements for comparable work and equal pay are satisfied.

Important qualification: This judgment does not establish that all temporary and permanent employees must receive identical compensation regardless of their duties or service conditions.

Practical significance: Employers should document objective reasons for pay differences and evaluate whether those differences are legally defensible rather than relying on historical payroll conventions.

Case 6: Mackinnon Mackenzie & Co. Ltd. v. Audrey D'Costa

Citation: (1987) 2 SCC 469.

Facts and issue: The case concerned unequal remuneration paid to male and female employees performing comparable work.

Legal principle: The Supreme Court examined equal remuneration obligations and the assessment of whether employees were performing the same or similar work under the applicable law.

Application to past practice: An employer cannot automatically defend a gender-based wage difference by stating that different pay scales have existed for many years. Historical payroll arrangements must satisfy the applicable equality requirements.

Practical significance: HR departments should review compensation structures for unlawful discrimination, using job responsibilities and other legally relevant factors rather than inherited assumptions or historical conventions.

Case 7: State of Punjab v. Gurdev Singh

Citation: (1991) 4 SCC 1.

Facts and issue: The case concerned the legal consequences of an allegedly invalid dismissal and the limitation period for seeking declaratory relief.

Legal principle: An employee's contention that an employment order is invalid does not necessarily eliminate the applicable limitation requirements. A claim must be brought through the appropriate legal proceeding within the prescribed period.

Application to past practice: Even where an employer has followed a disputed practice for years, an employee challenging its legality must consider the applicable limitation rules and available remedies. Equally, the employer should not assume that historical acceptance conclusively validates an unlawful action.

Practical significance: Employers and employees should distinguish between the substantive legality of a decision and the procedural rules governing when and how it can be challenged.

Case 8: State of Punjab v. Jagdip Singh

Citation: AIR 1964 SC 521; (1964) 4 SCR 964.

Facts and issue: The case concerned appointments to public office and the legal consequences of appointments made contrary to the governing requirements.

Legal principle: Public appointments must comply with the applicable legal framework. An appointment made in violation of mandatory requirements cannot automatically acquire legal validity simply because the individual has been treated as holding the position.

Application to past practice: A department cannot ordinarily validate an appointment that violates mandatory recruitment requirements merely because comparable appointments were made in the past.

Practical significance: Public-sector employers should audit appointment records and ensure that established recruitment practices comply with the governing rules and constitutional requirements.

5. Comparative analysis: Past practice versus legal requirement

6. How courts and employers should analyse a conflict

A systematic legal assessment should consider the following steps.

Step 1 — Identify the governing legal requirement

Determine the applicable legislation, rules, certified standing orders, binding award, settlement and employment contract. Confirm which provisions apply to the employee and relevant period.

Step 2 — Establish the past practice

Collect policy versions, payroll records, circulars, emails, employee handbooks, prior decisions and evidence of how consistently the practice was followed.

Step 3 — Determine whether a genuine conflict exists

A practice may supplement a legal rule without contradicting it. Identify the precise provision that conflicts and assess whether the law permits exceptions or alternative arrangements.

Step 4 — Determine the legal effect of the practice

Consider whether it is merely a discretionary custom, an incorporated contractual term, a binding settlement, a legally recognised custom or evidence relevant to fairness and consistency.

Step 5 — Correct the conflict lawfully

Stop or modify the unlawful practice, assess any accrued employee entitlements, follow required consultation or notice procedures, preserve relevant records and communicate the change accurately.

7. Practical employment-law examples

Example A: Long-standing denial of overtime

An employer has historically refused overtime payment unless a manager approved it in advance. An employee performs qualifying overtime work without obtaining approval.

Legal analysis: The employer must determine whether the work qualifies for overtime under the applicable law and whether any statutory exemption applies. The absence of prior approval may be relevant to discipline or internal controls, but it does not necessarily extinguish a statutory wage entitlement.

Recommended response: Investigate the actual hours worked, the employee's eligibility, applicable wage rules and the employer's authorisation process separately.

Example B: Promotion through an unwritten convention

A department has traditionally promoted employees based on length of service, even though the applicable service rules prescribe eligibility criteria and a selection procedure.

Legal analysis: The customary method cannot replace mandatory service rules. Past promotions do not automatically establish a legal right to further promotions under the same unlawful method.

Recommended response: Apply the governing rules, investigate any prior procedural irregularities and assess affected employees' rights under the applicable law.

Example C: An allowance paid for many years

An employer has paid a fixed allowance to a group of employees for a decade. A new HR manager stops payment because the written policy does not expressly mention the allowance.

Legal analysis: The absence of an express policy provision does not conclusively determine the issue. The allowance may have become part of the contractual arrangement, or its payment may have been discretionary. The nature of the benefit, employment documents, applicable law and established conduct must be examined.

Recommended response: Do not discontinue the allowance solely on the basis that the current written policy is silent. Establish its legal status first and follow any required procedure for changing it.

Example D: Unequal treatment defended as tradition

A company has historically offered a particular benefit only to one gender or employment category, without a documented, legally defensible basis.

Legal analysis: Historical consistency alone does not establish legality. The employer must assess the applicable equality and employment protections, the nature of the benefit and any lawful distinctions between the groups.

Recommended response: Conduct a structured equality review and correct any unlawful differentiation.

8. Remedies and consequences of an unlawful past practice

Depending on the governing law, employment status and facts, an affected employee or representative may seek:

Payment of unpaid wages, allowances or other legally due benefits.

Correction of service records or an unlawful employment decision.

Reconsideration of promotion, seniority or eligibility under applicable rules.

Reinstatement, compensation or other relief where legally available.

Relief through labour authorities, labour courts, industrial tribunals or constitutional courts, where jurisdiction exists.

Enforcement of a binding settlement, award or applicable service rule.

An employer may also face financial liability, regulatory action, adverse judicial findings or consequences arising from unfair labour practices, depending on the violation.

A longstanding practice does not automatically make every past decision void, nor does every departure from a practice establish unlawful conduct. The applicable legal remedy and any limitation period must be assessed independently.

9. HR compliance checklist

Employers should periodically review long-standing workplace practices against current legal requirements.

Compliance review

0 of 8

Identify statutory and regulatory requirements applicable to each practice.

Compare written policies, standing orders, contracts and settlements.

Review historical payroll, leave, promotion and disciplinary records.

Identify practices that may create contractual or other enforceable rights.

Investigate inconsistent or discriminatory treatment across employee groups.

Assess accrued entitlements and potential retrospective liabilities.

Obtain legal review before changing a potentially binding practice.

Document the reason, authority, effective date and communication of any change.

Reset checklist

10. Conclusion

The legal position is that past practice cannot, by itself, legitimise conduct that violates a mandatory legal requirement. In Indian employment law, the governing legislation, binding service rules and applicable legal obligations must be identified before deciding whether an established workplace practice can continue.

At the same time, past practice is not legally irrelevant. It can help establish the meaning of an employment arrangement, the existence of a benefit, the consistency of management decisions or the fairness of a particular action.

The appropriate approach is therefore to distinguish between:

A practice that is unlawful and must be corrected.

A lawful practice that has become a contractual or otherwise enforceable entitlement.

A discretionary practice that may be changed subject to applicable restrictions.

A practice that supplements the law without contradicting it.

The eight judgments discussed above provide important guidance on statutory service rules, public recruitment, standing orders, equal remuneration and the legal consequences of employment decisions.

Legal scope note: This analysis is primarily based on Indian law. A definitive opinion on a particular dispute requires the relevant statute, employment documents, applicable state or central jurisdiction, and the facts surrounding the practice.
