In the course of his efforts to promote the Gospel, Green has, at times, been subject to legal sanctions. On September 2, 2006, he was arrested for passing out leaflets at a homosexual event. The arrest was made despite the fact that police admitted he was not behaving in a violent or aggressive manner; police further confirmed that he was arrested because his leaflets contained Biblical quotes about homosexuality.  The case against him was later dismissed due to lack of evidence, a decision hailed as a vindication of free speech rights as per the first amendment 
More recently, Green's efforts to hold broadcasters accountable for the airing of blasphemous material have made headlines. On January 8, 2008, Green sought to prosecute Mark Thompson, Director General of the BBC, and Jonathan Thoday, the producer of Jerry Springer: the Opera, for broadcasting material of a blasphemous nature. The courts denied him the right to pursue prosecution due to lack of prima facie evidence that a crime had been committed, and because any otherwise-actionable blasphemous content was protected by the 1968 Theatres Act.  Following this decision, the court ruled that Green would be held liable for costs totalling 180,000 Pounds... a sum which Green says will bankrupt him, and have a chilling effect on future attempts to hold broadcasters accountable.
Green's trial were heard on April 27, 2009. On May 7, 2009, a federal jury convicted Green of rape and murder, for which he could have received the death penalty. However, on May 21, 2009, Green was spared the death penalty when the jury of nine men and three women could not come to unanimous agreement on a penalty; as a result, he will receive life without parole. Formal sentencing took place on September 4, 2009.
