After a number of investigations the Lord Advocate of Scotland and a Grand Jury of the United States charged and indicted two Libyan nationals, Abdel Basser al-Mergrahi and Al-Amin Khalifa Fahima, of complicity in the bombing. The UK and the US demanded the rendition of two named Libyan suspects accused aircraft sabotage of involvement in the placing of a bomb on the Pan American airliner Flight 103 on 21 December 1988, which blew up over the Scottish town Lockerbie, so that they could face trial in New York or Scotland. Libya rejected the demand, stating that it would investigate the case itself and asking for the evidence in the hands of the American and British prosecutors to help to do so. Libya noted that it was legally not in apposition to extradite its own nationals. Libya then brought against the US and the UK at the International Court of Justice, the Court's treatment of Libya's request for provisional measures showed that it was alive to this point. On this premiss Libya ask the Court on 3 March 1992 to indicate provisional measures that the UK and US should cease and desist from threats and further action against Libya. The Court opened its hearings on the request for the indication of provisional measures on 26 March 1992, with the President of the case declining to use his discretionary powers under Article 74 (4) of the Rules of the Court to call upon the parties to the dispute to act in a way which would not prejudice any future Order on provisional measures. Five public sittings of the Court followed on 26, 27, and 28 March with both parties presenting oral arguments on the request for the indication of provisional measures. Libya maintains that the US and the UK breached their legal obligations under the 1971 Montreal Convention for the Suppression of Unlawful Acts against the Safety of Civil Aviation by, inter alia,demanding that Libya surrender the alleged offenders for trial either in Scotland or in the United States. Libya arguing that the acts alleged constituted an offence under the Montreal Convention, and that the UK and US were in breach of the convention by virtue of the pressure they were placing on Libya to surrender the two Libyan nationals for trial. It is far from clear that Libya is in breach of its obligations under the Montreal Convention. The primary duty of a State is to submit a case to its prosecutor if it does not extradite the fugitive. Libya has made elaborate gestures of its willingness to do this. Even if there were a duty to extradite, that duty is to be exercised in accordance with national extradition law and Libya may not, according to that law, surrender its nationals. In any event, the fugitives have an arguable case that the offences are political character and thus non-extraditable. It may yet be that there are legal questions to be raised on the merits about the right of the Security Council to proceed in the way that it has, and political questions about the influence of the Western permanent members of the Security Council's decision-making. It appears that the Security Council in the Lockerbie Cases as an innovation which may be relied upon for the enforcement of the counter-terrorism treaties. Whether terrorist State exception is applicable in this case or not that is another issue. Libya had questioned whether they would have a fair trial if they were surrendered. However, this is irrelevant to some extent because the Security Council requests in its Resolution 731(1992) to extradite two Libyan suspected bombers to the United Kingdom or the United States for trial. On 31 March 1992, the Security Council passed a Resolution 748 (1992), which makes no express reference to Chapter VII, is concerned with the threat to international peace and security posed by Libya's support for terrorism, imposed a relatively restricted range of sanctions upon Libya due to its refusal to renounce terrorism, and demand that the accusers be handed over two suspected bombers makes with no reference to the Montreal Convention. The Security Council requests in its Resolution 748 (1992) and Resolution 883 (1993) surrender two Libyan suspects and to impose sanctions against the Libyan Arab Jamahiriya for its failure to comply. The rendition of the men is only one of the steps required to be taken by Libya with the object of removing the threat to international peace. These sanctions imposed a mandatory arms and air embargo upon Libya. It also called upon States to reduce significantly the number and the level of staff at Libyan diplomatic mission and diplomatic posts. A Committee was deseign up to monitor compliance with the sanction. Upon the certification by the Secretary-General of the arrival of the two accused Libyan indictees in the Netherlands for trial, thus the Security Council passed the Resolution 1192 (1998) provided, inter alia, for the suspension of the sanctions. Sanctions on Libya had been suspended. Libya and the UK and the USA reached an agreement in 1998 and the Security Council endorsed and mandated the arrangements for the trail. This duly occurred and the President of the Council issued a statement on 9 July 1999 noting therefore the suspension of the sanction. The Scottish Court presiding over the trial of the two Libyans accused of bombing Pam Am Flight 103 on 21 December 1988, has found Abdel Basser al-Mergrahi guilty of murder and sentence of life imprisonment under Scottish law. With regard to Al-Amin Khalifa Fahima, the Court concluded that the Crown failed to present sufficient evidence to satisfy the high standard of proof beyond reasonable doubt that is necessary in criminal cases. This does not mean that defendant is innocent of the crime charged. The Government of Libya must take responsibility. The sanctions on Libya were formally revoked by S.C. Resolution 11506 (2003) on the Libyan government's acceptance of responsibility for the Pan Am 103 bombing, its renunciation of terrorism and the payment of appropriate compensation to the victim's families. The purpose of this article is to examine various implications of the 1992 Aerial Incident at Lockerbie Cases. The article divides into four sections. The first section analysis international conventions regarding to crimes committed on aircraft as well as unlawful acts of violence at airports serving International Civil Aviation. The second section explores Lockerbie Cases. The third section discusses the power limit between the International Court of Justice and the United Nations Security Council focus on justiciable and non- justiciable disputes, as well as judicial review in respect of the Security Council Resolution. The four section considers international terrorist issues on conflicts of jurisdiction, legal responsibility, and international criminal assistance. It also addresses that a new framework of international law that confronts modern threats is long overdue. If it is to revive the legitimacy of international law, this order must be predicated on a new principle, under which individual States assume reciprocal obligations to contain transnational threats emerging from within their border.
