Kirk Jenkins brings a wealth of experience to his appellate practice, which focuses on antitrust and constitutional law, as well as products liability, RICO, price fixing, information sharing among competitors and class certification. In addition to handling appeals, he also regularly works with trial teams to ensure that important issues are properly presented and preserved for appellate review.  Mr. Jenkins is a pioneer in the application of data analytics to appellate decision-making and writes two analytics blogs, the California Supreme Court Review and the Illinois Supreme Court Review, as well as regularly writing for various legal publications.

Last time, we began reviewing the performance of each District and Division of the Appellate Court for the years 1990 to 2017 using a different metric: average votes each year to affirm the Appellate Court’s decision, regardless of whether the ultimate result was to affirm or reverse.  After reviewing the numbers for Chicago’s First District

For the past two weeks, we’ve been reviewing the reversal rates before the Supreme Court of each District and Division of the Appellate Court since 1990.  But not all affirmances (or reversals) are created equal.  A 4-3 reversal is arguably a different thing than a 7-0 reversal (and the same goes for affirmances by those

Yesterday, we reviewed the District-by-District reversal rates in criminal cases for the courts of Chicago’s First District.  Today, we’re reviewing the data for the rest of the state.

But first, let’s review the criminal cases decided in the First District for which we couldn’t determine a specific Division (the vast majority of these cases fall

Last week, we reviewed the data on reversal rates for the various Districts and Divisions of the Appellate Court in civil cases at the Supreme Court.  This week, we’re taking a look at the criminal docket.

In Table 918, we report the overall reversal rate for each intermediate Court in the 1,361 criminal and quasi-criminal

Last time, we reviewed the three-year floating reversal rate in civil cases from 1990 to 2017 of the Divisions of Chicago’s First District of the Appellate Court.  This time, we’re turning our attention to the rest of the state.  For Districts Two through Five, the highest long-term reversal rate was the Fifth District – 72.83%

This week, we’re looking at one of the most frequently seen analytics about appellate decision-making and courts of last resort: which Appellate Court has the highest (and lowest) reversal rate.  First, a few words about method.  We define criminal and quasi-criminal cases in our database as criminal, quasi-criminal cases like habeas corpus, juvenile and mental

Yesterday, we took a closer look at last week’s analysis of the unanimity rate, asking how much of the docket was accounted for by one, two and three dissenter cases.  Over the entire period 1990-2017, 12.86% of the criminal decisions had one dissenter, 10.65% had two – both slightly below the rate in civil cases

Last week, we discussed the evolution of the Court’s rate of unanimity in civil cases.  But of course, that analysis omits important variables – how was the dissent distributed?  It tells us something very different if, for example, the entire group of divided decisions were 6-1 or 4-3.  So this week, we’re looking at that
