Quantifying the Contours of Power: Chief Justice Roberts & Justice Kennedy in Criminal Justice Cases

This Article seeks to contribute to the debate with an empirical analysis of voting behavior in criminal justice cases decided during the first ten Terms of the Roberts Court era. The following section presents the study’s case selection and introduces the types of measures used to illuminate influence on the High Court (Part II). Court- and individual-level tendencies (Part III) identify potential spheres of influence occupied by Chief Justice Roberts and Justice Kennedy. These bases of judicial power are examined separately in Part IV (Chief Justice Roberts) and Part V (Justice Kennedy).

Some possible implications of Justice Scalia’s death on these power bases are addressed in Part VI.
