1. Introduction

Liability during inactive or maintenance phases concerns the legal responsibility of individuals, companies, operators, manufacturers, service providers, and regulators when a system, facility, technology, or biological process is temporarily inactive, suspended, undergoing maintenance, or awaiting reactivation.

The issue is particularly important in biotechnology, genetic engineering, laboratories, medical devices, pharmaceutical manufacturing, biological storage facilities, artificial intelligence systems, and industrial infrastructure. A system does not necessarily become legally risk-free merely because it is switched off or is not being used.

For example, a biotechnology company may suspend a gene-editing experiment while retaining genetically modified organisms in storage. Even during inactivity, inadequate temperature control, failure to monitor biological samples, accidental release, or delayed maintenance could cause injury or environmental damage.

The central legal question is:

Who bears responsibility when harm occurs during a period in which a system is not actively operating but remains under someone's ownership, custody, control, or regulatory responsibility?

The answer depends on the applicable jurisdiction, the nature of the hazard, statutory duties, contractual arrangements, foreseeability of harm, and the conduct of the parties involved.

2. Meaning and scope

The expression covers several distinct situations.

These categories can overlap. A facility may be inactive operationally but remain active legally because statutory monitoring, environmental safeguards, employee protections, or contractual obligations continue.

3. Legal principles governing liability

A. Duty of care continues during inactivity

A person or entity responsible for a dangerous system may remain under a duty to take reasonable precautions even when the system is not operating. The relevant question is whether the risk persists and whether the defendant retains responsibility or control.

Examples include:

Failure to monitor refrigerated biological samples during a laboratory shutdown.

Leaving defective electrical equipment connected during maintenance.

Allowing hazardous chemicals to remain in an inadequately secured facility.

Failing to warn workers about residual risks during servicing.

Neglecting inspection requirements during a temporary closure.

Liability generally requires an applicable legal duty and the necessary connection between a breach of that duty and the resulting harm. In some statutory regimes, however, liability can arise under stricter standards without proof of ordinary negligence.

B. Negligence and omission

Negligence may arise from an unreasonable failure to act. During inactivity or maintenance, relevant omissions can include:

Failure to conduct required inspections.

Failure to isolate hazardous equipment.

Failure to preserve biological materials safely.

Failure to follow maintenance procedures.

Failure to communicate known defects.

Failure to verify that a system is safe before restarting it.

A claimant will ordinarily need to establish the elements required by the applicable law, including duty, breach, causation, and legally recognized damage. A maintenance defect alone does not necessarily establish liability for every subsequent injury.

C. Strict and absolute liability

Certain hazardous activities attract liability beyond ordinary negligence principles.

In India, the Supreme Court's decision in M.C. Mehta v. Union of India, AIR 1987 SC 1086, commonly known as the Oleum Gas Leak case, established the principle of absolute liability for enterprises engaged in hazardous or inherently dangerous activities. The Court held that such enterprises have a non-delegable obligation to prevent harm arising from those activities.

ESCR-Net+1

This principle is particularly relevant where a hazardous installation remains dangerous during shutdown, storage, repair, or decommissioning. Nevertheless, its application depends on the nature of the activity, the facts, and the relevant legal framework; it should not be treated as a rule imposing absolute liability on every inactive facility.

D. Contractual allocation does not always eliminate legal responsibility

A contract may allocate maintenance duties between an owner, operator, manufacturer, and specialist contractor. However, contractual allocation does not automatically extinguish statutory obligations or duties owed to injured third parties.

A company may retain responsibility for supervising contractors, providing safety information, or complying with non-delegable statutory obligations. A contractor may separately be liable for negligent inspection or repair.

The distinction between liability to the victim and the allocation of costs between contracting parties is essential.

4. Important case laws

The following decisions provide relevant principles. Some directly concern maintenance or hazardous facilities; others establish broader rules that apply by analogy. They do not all concern inactive biotechnology systems specifically.

Case 1: M.C. Mehta v. Union of India (1987)

Supreme Court of India · AIR 1987 SC 1086 · Oleum Gas Leak case

Facts: Oleum gas escaped from a hazardous industrial establishment in Delhi, raising questions about industrial safety and the responsibility of enterprises conducting inherently dangerous activities.

Legal issue: What standard of liability should apply when a hazardous industrial activity causes harm to members of the public?

Decision and principle: The Supreme Court articulated the doctrine of absolute liability for enterprises carrying on hazardous or inherently dangerous activities. Such enterprises cannot simply rely on the traditional exceptions associated with the English rule in Rylands v. Fletcher to avoid responsibility.

Relevance to inactive or maintenance phases: A temporary shutdown does not itself establish that every hazard has disappeared. If a hazardous installation remains under an enterprise's control and causes harm through a residual danger, the enterprise may face liability under the applicable hazardous-activity principles.

Significance: The case supports a preventive approach to industrial safety and demonstrates why hazardous installations require appropriate safeguards beyond active production periods.

Case 2: Indian Council for Enviro-Legal Action v. Union of India (1996)

Supreme Court of India · (1996) 3 SCC 212

Facts: Industrial units in Rajasthan caused serious environmental contamination through hazardous chemical operations and inadequate management of pollution.

Legal issue: Who must bear the cost of environmental damage caused by hazardous industrial activity?

Decision and principle: The Supreme Court applied the polluter-pays principle and required the responsible industries to bear the costs associated with remedying the environmental harm.

Relevance to maintenance and decommissioning: Environmental liability may continue after production stops if contamination remains, remediation is incomplete, or hazardous waste is abandoned. Closing a plant does not automatically extinguish responsibility for damage attributable to its operations.

Significance: The decision is important for abandoned laboratories, chemical plants, biotechnology facilities, and contaminated industrial sites. Liability may include remediation costs in addition to other legally available relief.

Case 3: Vellore Citizens' Welfare Forum v. Union of India (1996)

Supreme Court of India · (1996) 5 SCC 647

Facts: Industrial pollution associated with tanneries in Tamil Nadu threatened water resources, agricultural land, and the surrounding environment.

Legal issue: How should Indian law address industrial development that creates a risk of serious environmental damage?

Decision and principle: The Court recognized the precautionary principle and the polluter-pays principle as essential features of Indian environmental law.

Relevance to inactive phases: Where a facility is suspended, dismantled, or awaiting maintenance, uncertainty about residual environmental risks does not necessarily justify inaction. Appropriate preventive measures, investigation, and remediation may be required under the applicable environmental law.

Significance: This case supports risk-based maintenance and decommissioning policies, particularly where delayed intervention could cause persistent environmental damage.

Case 4: Palka v. Servicemaster Management Services Corp. (1994)

New York Court of Appeals, United States · 83 N.Y.2d 579 (1994)

Facts: A nurse was injured when a wall-mounted fan fell in a hospital. A maintenance contractor had assumed extensive maintenance and safety-management responsibilities.

Legal issue: Could the maintenance contractor owe a duty of care to an injured person who was not a party to its contract with the hospital?

Decision and principle: The court held the contractor potentially liable because its comprehensive maintenance responsibilities gave rise to a duty extending to foreseeable third parties within the scope of the safety services undertaken.

Relevance to maintenance phases: An organization that assumes responsibility for inspections, preventive maintenance, or equipment safety may face liability if negligent performance of those functions causes injury, even where the injured person did not sign the maintenance contract.

Significance: The decision illustrates how a maintenance provider's assumed responsibilities can create duties beyond its immediate contractual relationship. Its precise rule is jurisdiction-specific.

Case 5: Espinal v. Melville Snow Contractors, Inc. (2002)

New York Court of Appeals, United States · 98 N.Y.2d 136 (2002)

Facts: An employee slipped in a parking lot after a contractor had performed snow-removal services.

Legal issue: Does a maintenance contractor automatically owe a tort duty to every third party affected by the condition of the premises?

Decision and principle: The court explained that a contractor's agreement with a property owner does not automatically create a duty to all third parties. Recognized exceptions include circumstances where the contractor creates or exacerbates a danger, where a third party detrimentally relies on its performance, or where the contractor entirely displaces the owner's safety obligations.

Relevance to inactive systems: Merely being hired to maintain an inactive facility does not automatically make a contractor liable for every accident occurring there. The nature of the work, the contractor's conduct, the risks created, and the extent of responsibility assumed must be examined.

Significance: This case provides a useful counterbalance to Palka: maintenance responsibility can create liability, but its scope is not unlimited.

Case 6: Hindustan Agro Chemicals Ltd. v. State of Rajasthan

Supreme Court of India · Reported decision concerning industrial closure and safety

Facts and issue: The litigation raised concerns about closure orders affecting industrial plants, including the risks associated with abruptly disconnecting electricity to a continuous-process chemical plant.

Legal principle: The case highlights the need for public authorities to exercise their regulatory powers responsibly, taking account of foreseeable safety consequences when directing industrial shutdowns.

Relevance to inactive phases: Shutdown itself can generate hazards. Where a process requires an orderly and technically safe stopping procedure, the authority directing closure and the operator implementing it may need to consider foreseeable consequences within their respective legal duties.

Significance: The case is useful in analysing the interaction between regulatory enforcement, operational safety, and responsibility for shutdown-related risks. It does not establish that regulators automatically become liable for every incident following a closure order.

5. Who may be held liable?

Responsibility depends on who controlled the hazard, what duties applied, and whose conduct caused the damage.

More than one party may be liable for the same incident. A court may need to distinguish between direct negligence, vicarious liability, statutory liability, and the contractual allocation of losses.

6. Application to biotechnology and biological systems

Inactive biotechnology systems present distinctive problems because biological risks may persist without active intervention.

A. Biological sample storage

If a laboratory suspends research but retains cell cultures, tissue samples, engineered organisms, or genetic materials, it may still have duties concerning secure storage, temperature control, access restrictions, and required monitoring. Liability depends on the governing rules and whether a breach causes legally recognized harm.

B. Maintenance of biomanufacturing facilities

Equipment maintenance may expose workers to chemical, biological, electrical, or mechanical hazards. Failure to isolate equipment, manage contamination, or follow safe-work procedures can support negligence or statutory claims.

C. Biosafety containment

A containment system that is inactive may still hold hazardous biological material. Depending on the material and applicable regulations, containment integrity, access control, incident response, and monitoring obligations may continue throughout the shutdown.

D. Decommissioning and abandoned facilities

Ceasing operations does not necessarily end obligations concerning hazardous waste, contaminated land, stored materials, or remediation. The responsible party may remain liable for residual damage even after the facility closes.

These examples illustrate potential legal issues, rather than establishing that any particular activity is unlawful or automatically gives rise to liability.

7. Applicable Indian legal framework

The precise statutory provisions depend on the facility, substance, activity, and type of harm.

Environment (Protection) Act, 1986: Provides a framework for environmental protection and regulatory directions concerning hazardous activities and environmental risks.

Water (Prevention and Control of Pollution) Act, 1974: May apply where industrial discharge or contamination affects water resources.

Air (Prevention and Control of Pollution) Act, 1981: May apply to relevant industrial emissions and pollution-control obligations.

Factories Act, 1948, and applicable occupational-safety legislation: Workplace duties depend on the relevant period, commencement of replacement legislation, applicable rules, and the establishment's status.

Biological Diversity Act, 2002, as amended: May be relevant to regulated access to biological resources and associated obligations.

Environment (Protection) Act rules governing hazardous substances and genetically engineered organisms: Relevant requirements depend on the organism, activity, facility, and applicable approvals.

Contract Act, 1872: May govern contractual obligations, breach, indemnity, and recovery between owners, operators, and maintenance providers.

Constitution of India, Articles 21 and 32: May become relevant where environmental hazards implicate fundamental rights and the conditions for constitutional relief are satisfied.

A statutory duty may continue during temporary inactivity if the legislation, approval, permit, or applicable order requires continued compliance. The fact that no production is taking place is not, by itself, a defence to a breach of such a duty.

8. Defences and limitations

A defendant may challenge liability on several grounds:

No applicable duty: The defendant did not owe the claimant the particular duty alleged.

No breach: The maintenance or shutdown measures satisfied the applicable legal standard.

Lack of causation: The alleged omission did not cause the damage, or the required causal connection cannot be established.

No legally recognized damage: The claimant cannot establish the type of loss required for the particular cause of action.

Intervening events: An independent event may affect causation or the allocation of responsibility, subject to the governing law.

Contractual allocation: A valid indemnity or limitation clause may affect recovery between contracting parties, subject to statutory restrictions and public policy.

Compliance with applicable procedures: Proper records and evidence of reasonable precautions may support the defence, although compliance alone does not defeat every strict-liability or statutory claim.

Important distinction: A defence available in ordinary negligence proceedings may not be available under an absolute-liability or other strict statutory regime.

9. Evidence required to establish liability

In a dispute involving an inactive facility or maintenance period, the following evidence may be important:

Maintenance schedules, inspection reports, and equipment-service records.

Shutdown and restart procedures.

Risk assessments and hazard-control documentation.

Temperature, pressure, access-control, and containment logs.

Records of biological sample custody and storage conditions.

Contracts allocating inspection, repair, and emergency-response responsibilities.

Employee training records and safety instructions.

Incident reports, photographs, expert assessments, and environmental testing.

Regulatory permits, notices, inspection findings, and closure orders.

Evidence connecting the alleged failure with the injury, contamination, loss, or other damage.

Courts may also examine whether a party knew or ought reasonably to have known about a hazard and had a reasonable opportunity to address it.

10. Preventive compliance framework

Organizations can reduce legal exposure by implementing a documented inactive-phase safety programme.

1

Assign responsibility

Identify who is accountable for the facility, equipment, materials, monitoring, and emergency response.

2

Assess residual risks

Determine which hazards remain after operations stop and which safeguards must continue.

3

Secure and isolate

Use appropriate lockout, containment, access restrictions, and safe-storage procedures.

4

Maintain monitoring

Continue inspections, alarms, environmental controls, and recordkeeping where required.

5

Control maintenance work

Require suitable authorization, competent personnel, risk assessments, and verification of repairs.

6

Verify safe reactivation

Inspect, test, document, and obtain required approvals before restarting operations.

7

Manage final closure

Dispose of hazardous materials lawfully and complete required remediation and reporting.

This framework should be adapted to the applicable legislation, permits, technical standards, and actual hazards rather than treated as a universal legal checklist.

11. Conclusion

Liability during inactive or maintenance phases rests on a fundamental principle: suspension of operations does not necessarily suspend legal responsibility for residual risks.

The Indian Supreme Court's decision in M.C. Mehta v. Union of India establishes a particularly important rule for hazardous enterprises, while Indian Council for Enviro-Legal Action demonstrates that environmental obligations can extend to remediation of damage caused by industrial activity. The US decisions in Palka and Espinal help explain when maintenance contractors may, or may not, owe duties to third parties.

The final outcome in any dispute depends on the applicable law, the nature of the hazard, the parties' respective responsibilities, and the evidence establishing breach and causation—or the relevant statutory basis of liability.

For biotechnology and other hazardous systems, effective legal compliance therefore requires safety planning not only during active operations, but also throughout shutdown, storage, maintenance, decommissioning, and reactivation.

Scope note: This is a general legal analysis, not jurisdiction-specific legal advice. The statutory framework and case-law principles should be checked against the particular facts and current law before being relied upon in litigation or compliance decisions.
