Legislators overturned 10 vetoes, the highest one-year total in 180 years. In 1833, lawmakers overrode 12 vetoed bills granting divorces but the constitution at the time only required a simple majority vote. Since the switch to a two-thirds majority, the single-year record was three overrides in 2003.
Two controversial vetoes that the Republican-controlled legislature failed to overturn were are a tax cut bill and a gun-related bill.
An income tax bill would have reduced income tax rates for some taxpayers over a ten-year period. The annual reduction would only have taken effect if state revenues increased by at least $100 million over the three previous years.
The tax bill also would have decreased corporate income tax rates.
Nixon and Attorney General Chris Koster said if legislators overrode the tax bill veto, taxpayers could potentially seek refunds from three previous tax years. They said that could put a $1.2 billion hole in the state budget. Nixon withheld $400 million from the state budget in anticipation of an override and has since released the majority of those funds.
A gun-related bill would have voided federal gun control laws, criminalized the enforcement of federal gun control regulations, banned newspapers from publishing the names of gun owners and allowed designated school personnel to carry concealed weapons.
Nixon vetoed the gun bill because he said the nullification of gun laws unnecessary, unconstitutional and unsafe.
Of the 10 overriden vetoes, two affect local government. One bill, HB278, bans local government from prohibiting or restricting a celebration of any federal holiday on government property. The second bill, HB1035, allows a city to annex an area without a local public vote, including residents living in the area to be annexed.
