Hindawi appealed. The Lord Chief Justice upheld the sentence, saying "Put briefly, this was about as foul and as horrible a crime as could possibly be imagined. It is no thanks to this applicant that his plot did not succeed in destroying 360 or 370 lives in the effort to promote one side of a political dispute by terrorism. In the judgment of this Court the sentence of 45 years' imprisonment was not a day too long. This application is refused."
