Today, we’re reviewing the pattern of Justice Karmeier’s questions in oral argument on criminal cases.

When Justice Karmeier joins the majority of a simple affirmance or reversal, his questions show the expected pattern – he tends to more heavily question the losing side.  In affirmances, he averages 1.88 questions to appellants and 0.68 to appellees. 

For the past few weeks, we’ve been reviewing the oral argument questioning of individual Justices, attempting to answer this question: if the Court as a whole is likely to more heavily question the party who will lose the case, what about Justices planning to dissent from that result?  This week, we’re looking at Justice Karmeier’s

Yesterday, we reviewed the data on Justice Kilbride’s oral arguments in civil cases.  Today, we’re looking at the criminal cases.

As you can see from the Table below, Justice Kilbride asks very few questions in criminal oral arguments.  When he’s in the majority of an affirmance, he averages 0.48 questions to appellants, 0.3 to appellees.

Last week, we reviewed the academic literature studying oral argument analytics, and then compared the data for civil and criminal cases, both affirmances and reversals, to the outcome of those earlier studies.  This week, we’re digging deeper on that work.  For last week’s comparison, we aggregated outright reversals and split decisions: “affirmed in part, reversed in part.”  Now let’s disaggregate – compare outright reversals to split decisions.

Last time, we surveyed the academic research applying analytics techniques to appellate oral arguments and then reviewed the data for civil arguments at the Supreme Court since 2008.  In this post, we’re reviewing the data for the same period on the criminal side of the docket.

Today, we begin a new subject in our ongoing analytics study of the Court’s decision making – oral arguments.  Although the academic community has been producing analytics studies of appellate decision making for a century, the analytics study of oral arguments is a much more recent development.
