For the past few weeks, we’ve been analyzing the distribution of majority opinions among the Justices in civil, criminal and death penalty cases, and which Justices tend to write the longest (and shortest) opinions.  Today, we turn our attention to the Court’s criminal cases between 2008 and 2015.  Once again, we omit the death penalty appeals from this dataset to avoid skewing the results.

Over the past eight years, the most frequent author of non-death criminal majority opinions has been Justice Corrigan with 50.  Justice Chin has written 45 opinions, Justice Baxter 44, Justice Werdegar 39 and Justice Kennard 33.

In 2008, Chief Justice George led the Court with nine majority opinions.  Justices Corrigan and Werdegar were next with seven each, followed by Justice Baxter with six and Justice Kennard with four.  In 2009, Justice Corrigan led with nine majorities, followed by Justices Werdegar and Chin with six apiece, Justice Kennard with five and Chief Justice George and Justice Baxter with four each.  In 2010, Justice Baxter led with ten majority opinions.  Chief Justice George wrote nine, Justice Corrigan seven and Justice Kennard six.  In 2011, Justices Kennard and Chin led, each writing six majority opinions in non-death criminal cases.  Justice Corrigan was next with five.  In 2012, Justice Baxter led, writing thirteen criminal majority opinions (the busiest year anyone had during the period).  Justice Corrigan wasn’t far behind with 11, and Justices Kennard and Chin wrote seven apiece.  In 2013, Justice Chin led with seven majorities, followed by Justice Corrigan with six and Chief Justice Cantil-Sakauye and Justice Werdegar with five each.  In 2014, the majority opinions were almost evenly distributed – the Chief Justice and Justice Chin wrote five apiece, but Justices Corrigan, Kennard, Werdegar and Baxter wrote four each.  Last year, Justices Werdegar and Liu led, each writing five majority opinions.  The Chief Justice and Justice Chin wrote four each, and Justice Baxter wrote three.
