Referendums on appropriation powers of funds

Voters will have the chance to vote "yes" or "no" on two proposed amendments to the state constitution, regarding limits on the governor’s appropriation powers of funds.

The first reads, “Delegation of appropriation power. Shall section 35 (1) of article IV of the constitution be created to provide that the legislature may not delegate its sole power to determine how moneys shall be appropriated?”

The second reads, “Allocation of federal moneys. Shall section 35 (2) of article IV of the constitution be created to prohibit the governor from allocating any federal moneys the governor accepts on behalf of the state without the approval of the legislature by joint resolution or as provided by legislative rule?”

The amendments are brought forth by Republicans, who hope to remove the current requirement that the legislature pass a law to appropriate funds from the state treasury and require the governor receive legislature approval before spending federal funds. Under current law, Gov. Tony Evers has been able to allocate federal funds without legislature approval, like pandemic relief for child care and education.
