Ronen Avraham (Texas) has updated a tremendously useful resource for those assessing the impacts of various tort reforms. In the Database of State Tort Law Reforms (3rd), Ronen sets out to establish "one 'canonized' dataset will increase our understanding of tort reform’s impacts on our lives." Direct access to the dataset (in Excel) is found here. A more complete description of the project follows:
"... DSTLR (3rd) updates the DSTLR (2nd) and contains the most detailed, complete and comprehensive legal dataset of the most prevalent tort reforms in the United States between 1980 and 2008. ... The dataset records state laws in all fifty states and the District of Columbia over the last several decades. For each reform we record the effective date, a short description of the reform, whether or not the jury is allowed to know about the reform, whether the reform was upheld or struck down by the states’ courts, as well as whether it was amended by the state legislator."
