A report analyzing data from federal insurance cases filed since 2009 found a major upswing in the numbers of such cases over the last several years, and confirms that federal courts are far more likely to rule in favor of insurers than claimants.

The Insurance Litigation Report released by Lex Machina Tuesday sifted data from more than 93,000 insurance cases filed between 2009 and 2017. It reveals a large jump in automobile and  uninsured/underinsured motorist claims, which rose by 39 percent and 50 percent, respectively.
