If the Supreme Court upholds the earlier ruling, that could derail Mrs. May’s planned timetable for invoking Article 50 by the end of March and upset the government’s wider plans for the so-called Brexit, or the country’s exit from the European Union. In his opening remarks, the Supreme Court president, David Neuberger, said the case was simply about the law. But if she loses, as many legal experts have predicted, Parliament could in theory block the exit, as most lawmakers supported staying in the European Union. The Scottish government, which strongly opposes leaving the European Union and has been seeking ways to keep Scotland in the bloc, will also put forward its arguments. The decision to leave the European Union has raised tensions in Britain, and Ms. Miller has received death threats and been the target of other abuse.
