Missouri residents and government agencies could not use drones to conduct surveillance without a warrant under legislation advanced by the state House.
The measure would also prevent journalists and other organizations from using drones to observe private property without an owner's consent. State universities could still use unmanned aircraft to conduct educational research.
Missouri senators have given first-round approval to legislation that would reward the state's four-year institutions for good performance with more funding.
Under the measure endorsed Tuesday, public universities would establish performance criteria. The criteria would be used to determine how much extra money the institutions get during years the state can afford to increase college funding.
Missouri lawmakers appear to agree with Gov. Jay Nixon that public colleges and universities should get more money next year.
But some lawmakers want to put part of that money toward building improvements, instead of devoting it to operations as proposed by Nixon.
House Budget Committee Chairman Rick Stream says he wants to make use of a 2012 law that authorizes state money for college building projects that generate a 50 percent match through private donations.
