Notable cases

As a United States District Judge, Droney presided over such matters as a multi-district class action involving RICO and fraud charges in the national food service industry,^[8] the first sex trafficking criminal jury trial under the then-new federal child sex trafficking statutes,^[9] and the return of the famous television puppet Howdy Doody from private parties to the museum at the Detroit Institute of Arts.^[10]

While on the Court of Appeals, Droney authored the Ragbir opinion,^[11] which held that immigrants could not be deported in retaliation for their protected First Amendment speech, and Littlejohn v. City of New York,^[12] which eased the pleading standard for federal employment discrimination claims. He also provided the deciding vote for the Second Circuit in Windsor v. United States,^[13] which held that the Equal Protection Clause guaranteed the right of same-sex couples to marry, which was affirmed by the United States Supreme Court. He also dissented from the denial of en banc in the Microsoft email case, arguing that federal prosecutors could obtain emails of Microsoft customers that were stored abroad. Droney also joined in the Knight First Amendment Institute v. Trump opinion,^[14] which held that the President's Twitter account was a First Amendment-protected public forum and the President could not block unfavorable comments from that account, the panel opinion in CREW v. Trump,^[15] which held that the suit could proceed against President Trump for violation of the Constitution's emoluments clause for his profits from his hotels and restaurants, as well as the Vance v. Trump opinion,^[16] which held that the President's personal tax returns were not immune from production in response to a state grand jury subpoena. He also joined the opinion which required the disclosure of the Jeffrey Epstein court documents.^[17]
