Layoffs Mysteriously Averted By Non-Budgetary Bill

The procedural move that Scott Walker used to defeat the Democratic flee-abuster of his anti-union bill was to strip out enough provisions to make it non-budgetary. Which leaves this somewhat mysterious:

Gov. Scott Walker announced on Friday that he was rescinding layoff notices for 1,500 state workers after Wisconsin lawmakers approved his plan to cut collective bargaining rights and benefits for public employees. The approval, after nearly a month of angry demonstrations and procedural maneuvering, will create enough budget savings, Mr. Walker said, that layoffs will not be needed now.

How is that non-budgetary?
