R v Baillie, also known as the Greenwich Hospital Case, was a 1778 prosecution of Thomas Baillie for criminal libel. The case initiated the legal career of Thomas Erskine. Baillie, the Lieutenant-Governor of the Greenwich Hospital for Seamen, a facility for injured or pensioned off seamen, had noted irregularities and corruption in the hospital, which was formally run by the Earl of Sandwich. After his official reporting of the problems failed to bring about reform in the hospital, Baillie published a pamphlet that was critical of the hospital's officers, alleging that Sandwich had given appointments to pay off political debts; Sandwich ignored the pamphlet but ensured that Baillie was indicted for criminal libel. Baillie hired five barristers, including Erskine, then newly called to the Bar, and appeared before Lord Mansfield in the Court of King's Bench on 23 November 1778.
After four of the barristers had spoken, Mansfield announced that the court session would resume the next morning rather than continue into the night, which gave Erskine the time he needed to present a full speech rather than a brief comment. In it he accused Sandwich of cowardice and of orchestrating the attack on Baillie, arguing that Baillie was merely doing his duty by attempting to bring the problems with the hospital into the public eye, and was therefore not acting in bad faith. If the issues with the hospital were not acknowledged, Erskine claimed, the Royal Navy would be "crippled by abuses", with seamen no longer willing to risk their lives for a fleet that would fail to treat them well in their retirement. Erskine was successful in having Baillie found not guilty, and after leaving the court was met with a standing ovation; Emory Speer writes that "It is probably true that never did a single speech so completely ensure professional success".
From 1705 to 1865, the Greenwich Hospital for Seamen provided medical care to injured seamen and lodgings for those injured sailors who had been pensioned off or were unable to work on ships. Directed by an admiral, "it was more like a ship in port than a clinical facility ... its residents all wore navy uniforms; food was identical to that served on vessels (a weekly four pounds of meat and gallon of beer); the seamen received a full ration of tobacco each week; and time was told by the number of bells". The facility was established by Royal Charter and led by a group of commissioners.Captain Thomas Baillie was a respected sailor who, after retirement, had been appointed Lieutenant-Governor of the hospital. Here he found corruption, in breach of the Hospital's Royal Charter, and endeavoured to bring it to the attention of the directors hospital, the hospital's governors, and eventually the Lords Commissioners of the Admiralty.
