I was taken aback when I read Justice Breyer's reference to Prof. John Donohue's law review article about racial bias in Connecticut's administration of its capital sentencing scheme. That a United States Supreme Court Justice would quote an article about a study that was thoroughly rejected in litigation is astonishing. This is especially so in this instance, when the proponents of Donohue's study kept his written report from the habeas court to also block admission, on hearsay grounds, of the devastating and unqualified evisceration of his study by the state's expert.
I'm equally concerned that Justice Breyer cited the report without questioning the validity of Donohue's "egregiousness" scale. After all, Donohue just made up the scale and never tested it objectively to determine whether it indicated anything meaningful or relevant about Connecticut's capital sentencing scheme. Thereafter, when his egregiousness results--compiled by law students from scrubbed summaries--disagreed with the results dictated by the statutory criteria for imposing a death sentence--as evaluated by experienced prosecutors, judges, and juries based on all the evidence--Donohue determined that the latter were arbitrary.
