Last year, we highlighted Iowa’s groundbreaking law to end over-naming of defendants in asbestos and silica litigation. Now, just a year later, three more states have followed suit: North Dakota, Tennessee, and West Virginia. All three states enacted their own versions of legislation aiming to reduce and prevent the over-naming of defendants in asbestos cases. While all three of the bills share similarities, North Dakota’s bill is the most expansive of the three.
