Plastic Bag Ban: Town Ordinance vs. State Preemption

Fairview, a town of 42,000 residents, adopted a plastic-bag ordinance in March by a 6-3 town council vote. The ordinance bans single-use plastic bags at grocery stores and charges 5 cents for paper bags, citing litter cleanup costs of about $85,000 per year. In June, the state legislature passed a law, effective the same date, declaring that only the state may regulate 'containers and packaging' and that any local rule on the subject is 'void and unenforceable.' The state law sets a statewide recycling goal but no bag ban. Fairview's town charter, approved by voters, gives the town power to protect 'the health, safety, and welfare of its residents' unless an ordinance is 'inconsistent with general law.' A grocery association sues, arguing the town ordinance is invalid. The town argues that its charter authorizes local action and that the state law does not expressly mention bags, only packaging.

1. Which law-Fairview's ordinance or the state statute-generally prevails? Explain the constitutional principle and apply it to the charter language.

Local governments are not sovereign in the way states are; they are created by state law. A town's home-rule charter can grant broad authority, but it cannot override a valid state statute when the two conflict. Here the state law expressly says only the state may regulate containers and packaging and that local rules are void. Bags are commonly treated as packaging, and the town's charter itself makes local ordinances subject to 'general law.' The state law is therefore likely to prevail. This is not the Supremacy Clause, which ranks federal law above state law; it is the hierarchy between a state and its political subdivisions. The town's health-and-safety argument does not create independent authority to contradict a statewide rule. A court would ask whether the state law validly applies and whether it conflicts, not whether the town's policy is wise.

2. Suppose the state law only set a recycling goal and said nothing about local bag rules. Would Fairview's ordinance survive? Apply the charter's 'inconsistent with general law' clause.

The result could change. Without an express ban on local rules, a court would look for implied preemption: does the state scheme occupy the entire field, or does the local ordinance conflict with a state goal? A general recycling goal does not necessarily conflict with a bag ban; the town could argue its ordinance advances the same goal. The charter's 'inconsistent with general law' clause is the key. If the ordinance can operate alongside state law, it is not inconsistent. But if the state law creates a comprehensive, uniform container policy, a court might find the field occupied. The town would have the stronger case than in the actual facts because the state has not expressly voided local rules. Still, the town could not use home rule to authorize something the state constitution or statutes forbid.

3. How does this dispute differ from a conflict between a federal law and a state law?

Read the worked answer

Federalism divides power between the national government and the states, and both have independent constitutional standing. A state can challenge a federal law, and the Supremacy Clause makes valid federal law prevail. Cities and towns have no comparable sovereignty; they exist at the state's discretion. When a state preempts local law, the town cannot invoke 'federalism' to shield itself. It must rely on state constitutional home rule or statutory authorization. This case is therefore about state-local hierarchy, not national-state federalism. The same word 'preemption' can appear, but the legal foundation is different: federal preemption rests on the Supremacy Clause; state preemption rests on the state's control over its subdivisions.
