A plan to prohibit public disclosure of licensed gun owners is headed to the Governor, who has indicated he supports it.
The 42 to 1 Senate vote Friday would overturn a ruling earlier this year by Attorney General Lisa Madigan's office that the names are public under the Freedom of Information Act.
Madigan responded after the Illinois State Police refused to release the names to reporters. Roughly one million people are registered to own firearms in Illinois.
Names of people authorized to own guns would be declared secret under legislation approved by the Illinois House.
The state police would be barred from releasing information on people who have Firearm Owner Identification cards.
The House approved the bill 98-12 Friday. It now heads to the Senate.
The attorney general ruled last month that the list of people with FOID cards must be released under the state Freedom of Information Act.
Action on releasing information about Illinois gun permits is being postponed until a court finishes reviewing the issue.
Attorney General Lisa Madigan's office said Friday it will halt all procedural steps on its ruling that the names of people with Firearm Owner Identification cards should be made public.
A Peoria court has issued a restraining order barring release of the information.
