The Bag Ordinance: Who Actually Has the Power?
A city council passes an ordinance banning single-use plastic bags at grocery stores, effective January 1. A state statute enacted two years earlier says that "the regulation of solid waste collection and disposal is a matter of statewide concern and shall be administered exclusively under rules adopted by the state environmental agency." A grocery chain sues, arguing the city has no authority. The city responds that it is protecting its own residents and that its home-rule charter grants it power over local health and safety. A fourth-grade teacher in the district wants to use the case to teach federalism and the sources of governmental authority; a parent has emailed that the case is "too political" for nine-year-olds.

The question is preemption: does the state statute displace the city ordinance? It is not a question about whether banning bags is a good policy.
Framework:
- Local governments are creatures of the state. They have no inherent sovereignty; they exercise authority the state gives them.
- In Dillon's Rule states, a city has only powers expressly granted, implied, or essential to its purpose - a city ordinance conflicting with a state statute loses.
- In home-rule states, a charter city may have broader authority, but a statute that expressly occupies the field usually still controls.
Likely result: the phrase "shall be administered exclusively" is express field preemption, so the ordinance is probably invalid - subject to the state constitution.
Why it is genuinely uncertain: state constitutions differ; some courts require an unmistakably clear statement before finding preemption of local health-and-safety powers; and home-rule provisions vary. "Most likely" is the right register here, not "definitely."
Precision point worth teaching: the U.S. Supremacy Clause governs federal–state conflicts. It does not decide a city-vs-state dispute; that is settled by state law.
2. Is this too political for fourth graders? How do you frame it so the parent's concern is answered rather than dismissed?
Read the worked answer
The case is about authority, not about the merits. The teachable content is "who decides and why," which is squarely in the civics standard. The environmental argument is background, not the lesson.
Framing moves:
- Pose the question as "Who should decide?", not "Should bags be banned?"
- Have students read two short, neutral statements written by the teacher - the city's and the store's - and identify each side's reason, not take a side.
- If students do state a preference, require a reason drawn from the text: "I think the state should decide because the law says 'exclusively.'" That converts opinion into argument from evidence.
- Use a familiar parallel: the classroom rule vs. the school rule vs. the district rule. Nine-year-olds can already reason about overlapping authority; they just lack the vocabulary.
Reply to the parent: name the standard being addressed (state and local government, sources of authority), explain that students are analyzing a structural question rather than advocating a policy, and offer to share the two statements in advance.
Avoid: inviting students to argue the environmental merits, or framing either side as the "correct" one.
3. What misconception about federalism does this case let you head off, and what evidence would show a student still holds it?
Read the worked answer
The misconception: students picture government as a single ladder - federal on top, then state, then city, each able to command the one below. That model cannot explain why the city might lose here even though it is closest to residents.
What the case corrects: cities are not miniature states. States are constitutionally sovereign in a way cities are not; a city exists because a state charter or statute created it. So "closer to the people" does not equal "more authority."
Evidence a student still holds the ladder model:
- Says the city should win because "the city is more local, so it knows better" - a preference argument standing in for an authority argument.
- Says the Supreme Court will decide it - missing that this is a state-law question.
- Describes federalism as "the federal government giving orders to the states."
Check for understanding: give a fresh scenario - a county health rule vs. a state health rule - and ask who prevails and why. Transfer without the words "bag" or "plastic" shows whether the structure was learned or the story was memorized.
