Karnataka HC Refuses to Quash Case Against Firm for Relabeling Expired Food; Calls it 'Assault on Public Health'

The Karnataka High Court has refused to quash a criminal case against Earth Recycler Pvt. Ltd and its representatives for allegedly relabeling expired food products with fresh expiry dates and reselling them. The court termed this a 'calculated assault on public health' and held that such acts attract provisions of the Bharatiya Nyaya Sanhita (BNS) for cheating and public mischief, beyond mere regulatory infractions under the Food Safety and Standards (FSS) Act. This judgment reinforces the legal principle that food safety is not just a regulatory matter but a fundamental consumer health concern, and that criminal liability can be invoked for such deceptive practices.
