COLUMBIA, S.C. -Gov. Mark Sanford has vetoed four unsigned resolutions that would exempt schools in four counties from making up days missed because of inclement weather.

The bills are unconstitutional local legislation, Sanford said in letters to House Speaker David Wilkins and Lt. Gov. Andre Bauer, who presides over the Senate.

The governor suggested the Legislature establish a general statute that would say when a school would not be required to make up missed days or give school districts more autonomy.

The bills deal with missed days at schools in Chester, Dillon, Darlington and York counties.

Sanford has vetoed other local legislation before, saying he wants lawmakers to eliminate the long-standing practice of passing laws that affect only one county, which the state Constitution prohibits.
