Gov. Sonny Perdue signed the ethics bill into law on Tuesday.

It came after the state Department of Revenue revealed earlier this year that 22 state lawmakers - about 10 percent of the General Assembly - are delinquent on their taxes. Only three of those lawmakers' names have been made public. Legislators said they can't consider sanctions unless they know who they are.

The bill Perdue signed on Tuesday clears the way for state revenue officials to release the names of the offenders to the chairmen of the House and Senate ethics committees. The lawmakers would have 30 days to correct the problem.
