  "title": "A programme in another language still owes the English keyword",
  "statement": "A programme messaging in a language other than English must honour STOP in that language, and must not return an error to the English keyword.",
  "rationale": "A Spanish-language programme whose handler only knows English leaves its subscribers with no working opt-out at all, which is the worst version of this failure. The mirror case is just as real: handsets, carriers and habit mean somebody will send STOP even to a Spanish programme, and answering that with an error is the defect the previous rule describes.",
