Gov. Scott Walker’s budget repair bill would bust the budget of the state agency required to administer part of it, while creating a strange and difficult standard for unions to meet in order to continue to exist, said Peter Davis, general counsel for the Wisconsin Employment Relations Commission.

Walker’s bill would require the commission’s 20-person staff to conduct votes in up to 2,000 state and local government unions each April, Davis said Thursday.

“We would try, but there’s no way we could do it,” Davis said.

Walker spokesman Cullen Werwie didn’t respond to requests for comment.

Walker’s bill has touched off more than a week of massive protests at the Capitol. Walker says the law is needed to bridge projected budget gaps in the current and future fiscal years and to prepare schools and local governments to cut costs.

Attention has focused on a provision that would strip most public employee unions of most negotiating rights.

A provision that received less attention would require members of each public sector union to vote each year to continue operating. Those annual votes would require approval of 51 percent of a union’s membership to keep certification, Davis said.
