California’s Proposition 46 was soundly defeated on November 4th with 67% of the roughly 5 million votes cast against. California was the trailblazer in what is now known as ‘Tort Reform’ when its Medical Injury Compensation Reform Act (MICRA) was passed in the mid-1970s in the midst of a medical malpractice insurance premium crisis. MICRA’s key provision was to impose a $250,000 cap on non-economic damages. That cap has remained in place ever since.

Presented for your consideration are some facts about the measure, the insurance industry and California’s caps as compared to those in other states:
Approximately $9.6 million was spent by proponents of Prop 46. 
The majority was donated by attorney PACs and law firms. Major donors included:
Approximately $53.6 million was spent by opponents of Prop 46. 
Medical Malpractice insurance has been among the most profitable types of coverage as compared to other lines of property/casualty insurance for the past several years.
Note: The lower the percentage listed, the greater the profitability. Notice that the mortgage and financial guaranty segments remain the most unprofitable given the recent housing crisis leading to significant insurance claims.
A potential consequence of its profitability, the medical malpractice insurance market has undergone significant consolidation over the past decade. The Doctor’s Company, the largest medical malpractice insurance carrier in the U.S. and the largest contributor to defeat prop 46, has spent in excess of $1 billion acquiring more than 8 other medical malpractice insurance carriers over the past decade.
California is the fourth most expensive state to live in according to a recent CNBC study. By contrast, the non-economic damage caps initiated by MICRA in 1975 are the lowest of any in the U.S. While caps and specific rules regarding their application vary by state, the vast majority of states that have instituted such caps, are greater than the $250,000 cap currently in place in California. It might surprise many Californians to know that the maximum non-economic damage awards mandated by statute are more than $700,000 in places like Tennessee, Wisconsin and Maryland and $500,000 in states like Mississippi, Florida, North Carolina and the Dakotas.
Several states which legislated non-economic damage caps such as Illinois, Georgia and Missouri had those laws overturned in 2010 as they were deemed unconstitutional by high courts in those states.
