MADISON, Wis. -- Gov. Jim Doyle said a veto he made that's contrary to a constitutional ban is a "very little, minor point."

The ban passed in April 2008 prohibits governors from vetoing parts of two or more sentences to create a new sentence. The veto in question cuts from three sentences to make one new one.

It was one of Doyle's 81 budget vetoes when he signed the state budget Monday.

Asked about it Wednesday, Doyle called it "a very technical, little thing" that wasn't caught in two frenzied days of work by his staff on vetoes.

"We had a day and a half. People were working night and day in our budget office and this is all checked over by the Legislative Reference Bureau and frankly they just missed it; it's a minor little point," Doyle said.

The veto deleted creation of a study committee to look into mentally ill care facilities, leaving it to be done instead by a Doyle appointee.

Doyle said the study would go ahead as the Legislature wanted "and that will be the end of it."
