Lawyers for asbestos defendants argued at the Georgia Supreme Court on Monday that plaintiffs’ counsel have overblown the hurdles placed by new Georgia limits on asbestos and silica claims. Spectators packed the house to hear arguments on the constitutionality of the changes.

The cases considered by the court Monday involve asbestos claims of several dozen people pending in Cobb County Superior and State Courts against various companies, including Atlanta-based Georgia-Pacific Corp. In six separate orders, seven judges each declared unconstitutional the retroactive application of changes in Georgia law enacted last year.
