Court allows supermarkets in Marília to charge for plastic bags
The São Paulo Court of Justice (TJ-SP) has authorized supermarkets in Marília, São Paulo, to charge consumers for plastic bags, overturning a previous requirement for free distribution. This decision, made by a majority vote in the 12th Public Law Chamber of the TJ-SP and published on Tuesday, November 28th, addresses a long-standing debate since 2011 regarding municipal legislation that prohibits non-reusable plastic bags. The authorization to charge specifically applies to merchants represented by their union, not all supermarkets in the city.
Previously, a municipal law enacted on July 15, 2025, prohibited the free provision of conventional plastic bags, leading stores to charge R$0.13 per bag. However, in August 2025, the legislation was amended to mandate that supermarkets provide ecologically appropriate bags, such as the PAD 2 model, free of charge. This change prompted a legal challenge from retailers, represented by the Retail Trade Union of Marília, who argued that they should not bear the cost of these materials. Their legal action was grounded in the principles of free enterprise and economic freedom.
This judicial decision shifts the financial burden of providing compliant shopping bags from retailers to consumers in Marília, impacting market dynamics and consumer behavior. The ruling addresses the tension between municipal environmental regulations and commercial operational costs, highlighting the legal framework's role in mediating such conflicts. Moving forward, the long-term sustainability of such policies will depend on consumer adoption of reusable alternatives and the evolving economic landscape for retailers. This case illustrates the ongoing negotiation between public policy goals, such as reducing plastic waste, and the economic realities faced by businesses, particularly in the context of inflationary pressures and supply chain costs.
