Roberts granted a stay, pending the Supreme Court's disposition of a certiorari peition, of a decision by the Maryland Court of Appeals. The lower court had held a state law providing for the collection of DNA samples from defendants charged with certain crimes violated the Fourth Amendment. Roberts believed that the Court was likely to grant the cert. petition because the Maryland decision conflicted with decisions by the Third and Ninth Circuits and another state supreme court, and that it was likely to reverse the Maryland decision because of the strength of the analyses presented in those other courts' decisions. He also concluded that the decision, like any other that enjoined a statute, subjected Maryland to irreparable harm. Noting that 58 prosecutions had occurred between 2009 and 2011 because of DNA collection from Maryland arrestees, the lower decision also constituted "an ongoing and concrete harm to Maryland's law enforcement and public safety interests." A stay was, therefore, appropriate.
