At Prawfsblawg. News about the newly granted cert is at ScotusBlog. When Connick came down, I had thought that it signaled a new era in suing for Brady violations even though that plaintiff lost. The court's opinon suggested that while a single instance of Brady violation was not enough to sue the DA's office, a pattern would be. As a former plaintiff's lawyer, my reaction was "well that's easy enough to plead next time." Perhaps this new case will make clear when you can, and when you can't, sue the DA's office for Brady violations. My guess is that at some point, the powers that will have to write the check to successful plaintiffs will force DA offices to train about Brady and to adopt open file policies. Given the historical neglect of Brady duties, if the threat of damages awards incents better behavior, then bully for damages awards.
UPDATE: In the comments, Monroe Freedman points us to this New York Times article, written by Joanna Schwartz of UCLA, about the $500 in settlements and judgments that New York City has had to pay out to settle claims related to police conduct. (My quick view is that the premises of the article can be contested and, more pertinent to this post, I suspect that it may be easier to incent -- forgive me for that word -- better Brady training with lawyers than to get the police to behave in a way that results in no claims being filed.)
