Act of God or Natural Events:
- Explanation: This exception applies when the harm is caused by an unforeseeable act of God or a natural event that is beyond human control. In such cases, the defendant may not be held strictly liable because they cannot reasonably predict or prevent these events.
- Example: If a sudden and severe flood damages a dam, causing the release of water that damages downstream properties, the dam owner may not be strictly liable because the flood was an act of God.
Act of a Third Party:
- Explanation: When the escape of a dangerous element is solely the result of an unforeseeable act by a third party, the defendant may be exempt from strict liability. This exception recognizes that the defendant cannot always control the actions of others.
- Example: If a mischievous person intentionally damages a chemical storage tank, leading to a hazardous substance leak, the owner of the tank may not be held strictly liable because the escape resulted from the third party's actions.
Plaintiff's Default or Contributory Negligence:
- Explanation: If the plaintiff's own actions or negligence significantly contribute to the harm, it can serve as an exception to strict liability. In such cases, the plaintiff's conduct is seen as a factor that reduces the defendant's liability.
- Example: If a person enters a restricted area clearly marked as dangerous, ignoring warning signs and gets injured, their contributory negligence could limit the liability of the party engaged in the dangerous activity.
Statutory Authority:
- Explanation: This exception applies when the defendant is engaged in an activity that is authorized by statute or law. If the activity is conducted in compliance with the law, strict liability may not apply, as the defendant is acting within the boundaries set by the legal framework.
- Example: If a government agency conducts controlled explosions for mining purposes in accordance with relevant mining laws, and an unforeseen escape occurs, they may not be held strictly liable because they were authorized by law to conduct such activities.
Relevance in Indian Jurisprudence:
- Kesavananda Bharati v. State of Kerala (1973): While not directly related to strict liability, this case emphasizes that no law can violate the basic structure of the Indian Constitution, which includes principles of justice and equity. This can be invoked as an exception to strict liability if a law contradicts constitutional principles.
- Kharak Singh v. State of Uttar Pradesh (1963): This case underscores the importance of individual privacy rights as part of fundamental freedoms under the Indian Constitution. If strict liability infringes upon an individual's privacy rights, it might be challenged on constitutional grounds.
