Coincident with changes in the party imbalance of the Court over time, sharp discontinuities in these dependencies are evident. Overall, the patterns suggest a tradeoff between co-dependencies around political affiliations and individual ideologies, with more-equal party representation on the Court encouraging greater party awareness in Justice voting, and less-equal party representation allowing Justices across party lines but with similar ideologies to inform each other's votes. %K Supreme Court %K voting %K judicial behavior %K spatial econometrics
