The Minneapolis City Council recently voted to require employers to provide paid sick leave to employees. The requirement applies to firms with six or more employees and extends to all employers with employees doing business in Minneapolis.
On top of this being a bad idea that makes it harder to do business in Minneapolis, the City Council likely doesn't actually have the power to pass this regulation.
Minneapolis is a home rule charter city, which many people assume grants the city broad power to pass any law it wants. The Minnesota Supreme Court has explained that "in matters of municipal concern, home rule cities have all the legislative power possessed by the Legislature of the state." That seems like pretty broad power, but the breadth applies only to matters of "municipal concern."
"If a matter presents a statewide problem," according to the court, "the implied necessary powers of a municipality to regulate are narrowly construed unless the Legislature has expressly provided otherwise."
Paid sick leave is clearly a matter of statewide concern and, therefore, should not be subject to local regulation. This question was settled in a case where St. Paul tried to force contractors to use Ramsey County residents for any city work. In striking down the regulation, the state Supreme Court concluded that "under the St. Paul charter it would seem that the activity of laborers is a statewide matter and not one for local regulation so long as the activity is not inherently dangerous to the health, welfare, safety or morals of the people of the city."
It's easy to see why the state limits a city's power to matters of local concern.
In another case, the court rejected an attempt by Brooklyn Center to license boats after concluding that the lake-studded geography of Minnesota made licensing an issue of statewide concern. Imagine if everyone who owned a boat needed a different license to launch from city to city. Likewise, imagine if Minnesota's 107 home rule charter cities each passed its own version of paid sick leave. As the court explained in the boat-licensing case, the burden resulting from such multiplicity of rules would be "both unreasonable and absurd."
To avoid these absurdities, a city can pass a law on issues of statewide concern only when it is given explicit authority from the state.
