A legislative effort to force nonprofit hospitals to justify their tax-exempt status has been shelved for the year.

The bill from Democratic Assemblyman Bob Wieckowski of Fremont would have required the hospitals to provide more details about the charitable care they provide.

The California Nurses Association and other labor groups say the tax benefits nonprofit hospitals receive are far larger than the value of their charitable work.

The California Hospital Association and business groups opposed AB975. They say hospitals are following state law and warn that charitable care would be reduced under the proposed rules.

The legislation was among bills that were held over for next year during Friday's deadline session. On Thursday, it had failed on several attempts to get enough votes to pass.
