Land use folks might be interested in following a current bill in the Illinois legislature that would eliminate Dillon's Rule in the state. In Illinois, Dillon's Rule only applies to non-home rule local government units, which are defined as cities with a population less than 25,000 and counties without a CEO form of government (all but Cook County). In non-home rule jurisdictions, Dillon's Rule still applies, but the new legislation would grant the constitutional police power to those local governments. Interestingly, Illinois' constitutional grant of authority to local governments includes the police power along with the right to tax, incur debt, and license. The bill would not include the three latter powers in the grant of authority to non-home rule local government units. 

So will Illinois grant the police power to local non-home rule governments and end Dillon's Rule's…rule? Stay tuned…
