JEFFERSON CITY, Mo. -- Missouri Gov. Jay Nixon went on a vetoing spree Tuesday, knocking down legislation he described as giving "special interest tax breaks" and ones that would change the state's litigation policies.

Nixon also signed a number of proposals, including a sales-tax exemption for internet use and access.

"I am more than willing to sign tax breaks, as I have today and as I have in the past, as long as they make good sense for Missouri," Nixon said. "But any legislation that's going to further reduce the revenues we have to pay for things like schools, scholarships and public safety has to meet a high bar."

Here's a look at some of the bills Nixon vetoed, which aren't dead yet, as the Republican-led Legislature can try to override the vetoes during a short September session:

Tax breaks

Nixon called a bill that would exempt instructional classes -- including yoga, martial arts and dance studios -- from sales taxes a "loophole" and said it would punch a hole in the state budget that takes effect July 1 with an estimated $16 million cost to state and local revenue.

Bill sponsor Sen. Will Kraus, a Lee's Summit Republican, said in a statement he's "disappointed the governor prioritized revenue collection over keeping these classes affordable for Missouri families by vetoing this bill." He said he's looking forward to trying to override Nixon in September.

Another vetoed bill would have allowed an income-tax deduction for 50 percent of net capital gains when companies switch to employee ownership. Legislative researchers had estimated it could cost up to $10.3 million each year starting in fiscal year 2018.

The final tax break would have called for the state to give refunds to those who paid taxes on money from federal agricultural disaster payments.

Litigation

Nixon turned down two measures supported by the Missouri Chamber of Commerce and Industry.

Republican supporters have said the aim of the first vetoed measure was to ensure only out-of-pocket expenses of insurance companies and victims can be reviewed in a trial, not what's considered the cost of care, which could be higher. Currently, juries can review both out-of-pocket expenses and the value of medical treatments.

In his veto letter, Nixon said the bill would "limit recoveries by injured people, and unfairly favor those who cause the injuries."

Another vetoed proposal would have changed how judges admit expert testimony. Instead of basing it on facts "reasonably relied upon by experts in the field," courts would have admitted it after determining it was based on "sufficient facts" and "reliable principles and methods." It wouldn't have applied to juvenile courts or family courts, which handle adoption and divorce cases, and would have barred expert witnesses from attributing a defendant's actions to his or her mental state.

The bill's proponents had argued it would ensure expert witnesses are actually experts. But Nixon said the bill was "designed to make it more difficult and expensive for parties to bring forward their case and recover their proper damages."

Water commission and cows trespassing

Nixon also vetoed a bill that would have nixed a requirement to put members of the public on the Missouri Clean Water Commission, which is involved in overseeing the state's water quality.

He also turned aside a measure to change the liability of owners of cattle, horses and other livestock that break through fences and damage other people's property.
