The Senate voted unanimously Thursday to override then-Gov. Sonny Perdue’s veto last year of so-called zero-based-budgeting legislation.

Sen. Barry Loudermilk, R-Cassville, was a strong proponent of the bill as a House member in 2010 — and expressed dismay at Perdue’s veto.

“We’re going to try again next year,” he promised members of the Greater Rome Chamber of Commerce during a post-session report last summer.

All of Floyd County’s state House delegates supported the measure in a 151-0 vote last year. The measure, Senate Bill 1, passed the Senate, 50-0, in 2009. Gov. Nathan Deal said he has no problem with overriding the veto, which now goes to the House.

The bill requires the General Assembly to consider every penny appropriated to one-fourth of the state agencies every year, completing all in every four-year cycle. It is a departure from the current “continuation budget” practice in which all appropriations from the prior year are automatically continued unless lawmakers specifically cut them.

Proponents of zero-based budgeting argue that it forces consideration of all spending decisions. Such thorough consideration, they say, will uncover waste and duplication.

The Senate has passed zero-based-budgeting bills four times in the last eight years, three of them unanimously. Perdue blocked it from becoming law, he said in his veto message, because it would be too cumbersome and expensive for state agencies to prepare materials on every detail in a $17 billion budget.
