Legislation requiring workers to divulge all asbestos claims filed by or for them or face perjury charges cleared a Senate committee yesterday, sending it to an expected floor vote today. Proponents say companies can't know about potential double-dipping by victims, who sometimes seek damages from trusts set up by bankrupted companies and pursue damages from surviving businesses. The measure preserves victims' rights to sue when harmed by the powdery white carcinogen and wouldn't cap awards. Asbestos cancer victims say the bill impedes legitimate claims and protects corporations. Cuyahoga County has one of America's busiest asbestos dockets. Similar cases are pending in dozens of Ohio counties.
