Today, we announce a substantial expansion of the Illinois Supreme Court database. Matching the expansion earlier this year of the California Supreme Court database, the data on the Illinois Supreme Court has been expanded to include significantly more variables, as well as all the Court’s cases since January 1, 1990. During that time, the Court has decided 1,352 civil cases and 1,519 criminal cases. For the first half of our study period from 1990 through 2007, our database includes approximately 100 data points on each case. From 2008 through 2016 – the period for which all of the Court’s oral arguments are on line -we have approximately 125 data points for each case.
The database now includes the entire time on the Court of every currently sitting Justice, plus many others:
Join us back here tomorrow as review the full list of variables in the new database.
