The Supreme Court in Scotland rejected on Friday the third appeal against the conviction of Libyan citizen Abdelbaset Al-Megrahi found guilty of the 1988 Lockerbie bombing, the UK-based Telegraph newspaper reported.
The court concluded that Al-Megrahi "committed the worst terrorist attack in British history," according to the newspaper.
The family of former Libyan intelligence officer Abdelbaset Al-Megrahi has sought - since his death more than eight years ago- to quash the rule issued in 2001.
Al-Megrahi's family appealed against his conviction on the grounds of non-disclosure of evidence, which means that al-Megrahi did not receive a fair trial.
Al-Megrahi was convicted under Scottish law in a private trial in the Netherlands in 2001, after years of a diplomatic row between the United Kingdom and the United States on the one hand, and Libya on the other hand over his extradition.
