MADISON, Wis. — All Wisconsin administrative rules would be reviewed every nine years under a bill approved by the state Assembly.

Democrats and a broad array of other opponents fear such a move would make it easier to undo consumer, workplace and environmental protections and a host of other regulations. They have branded the measure passed Thursday as a special interest giveaway.

Republican supporters say the bill will ensure that state regulations stay current and relevant.

Americans for Prosperity and Wisconsin Manufacturers and Commerce are among the backers, arguing the change will protect people from undue regulatory burdens.

The proposal is the latest in a series of moves by the Legislature to rework the rule-making process. It now heads to the Senate.
