In the 1999 Legislature's general appropriations act, it set aside about $40 million to let up to 234 Florida schools extend their school year from a minimum 180 days to a minimum 210 days in fiscal year 1999-2000. Governor Bush exercised his line-item veto to eliminate some of the language in this appropriation. The Florida Senate contends his veto reduced the appropriation to $23.3 million in violation of constitutional principles requiring the Governor to either veto all or none of any "unified fund" in an appropriations act. The Governor argues that the sum he vetoed itself was a unified fund because the amount is identifiable in the Legislature's working papers. Thus, he believes he is constitutionally allowed to veto it.
