Earlier this week, we looked at the reversal rates of the various Districts and Divisions of the Court of Appeal in civil cases before the Supreme Court.  Today and tomorrow, we’re reviewing the data for the Court’s criminal docket.

But before we turn to the court-by-court numbers, let’s compare overall rates, both among the courts

Yesterday, we began our court-by-court review of the three-year floating reversal rates of every District and Division of the Court of Appeal in civil cases decided by the Supreme Court.  Today, we’re concluding that project with Divisions 5-8 of the Second District and the Third, Fourth, Fifth and Sixth Districts.

From 1990 to 2017, the

This week, we’re taking a close look at the reversal rates of the various Districts and Divisions of the Court of Appeal in civil cases.  As always, we’re defining “criminal” cases in the data as criminal prosecutions, quasi-criminal actions (habeas corpus), juvenile and mental health cases that arise out of alleged criminal activity, and attorney

This week, we’re following up last week’s posts by taking a closer look at how dissent was distributed at the Court between one, two and three dissenter cases.  Today, we’re looking at the criminal docket.  For the years 1990 to 2017, 11.32% of the Court’s 1,590 criminal cases had one dissenter, 11.89% had two and

Last week, we reviewed the year by year data, tracing the changes in the Court’s unanimity rate between 1990 and 2017.  But of course, that leaves out an important variable – a 6-1 decision tells us something very different from a 4-3 decision.  So how was the Court’s dissent distributed across one, two and three

Yesterday, we took a look at the Court’s unanimity rate in civil cases (60.18% in 1,223 cases).  Today, we’re looking at the criminal docket.  From 1990 to 2017, the Court decided 1,590 criminal, quasi-criminal, juvenile and disciplinary cases, with a unanimity rate ten points higher than on the civil side – 70.25%.

Just as was

This week, we’re turning our attention to a new issue, tracing how the Court’s unanimity rate has changed over time.  Between 1990 and 2017, the Court decided 1,223 civil cases, 60.18% of those by a unanimous vote.

From 1990 to 1996, the Court’s unanimity rate in civil cases was consistently below this long-term average: 41.03%

Yesterday, we began our comparison of the Illinois and California Supreme Courts’ criminal dockets for the past twenty-eight years.  We covered the years 1990 through 2003.  Today, we’re looking at the years 2004 to 2017.

From 1990 to 2003, the Illinois Supreme Court wrote more criminal decisions than the California Supreme Court did.  Since that
