Context: Pan Am Flight 103 was a regularly scheduled Pan Am transatlantic flight from Frankfurt to Detroit via London and New York.  On 21 December 1988, N739PA, the aircraft operating the transatlantic leg of the route, was destroyed by a bomb, killing all 243 passengers and 16 crew, in what became known as the Lockerbie bombing.  Large sections of the aircraft crashed onto residential areas of Lockerbie, Scotland, killing 11 more people on the ground. United Nations Security Council Resolution 2110 is a United Nations Security Council resolution adopted unanimously by the United Nations Security Council on 24 July, 2013, extending the United Nations Assistance Mission for Iraq until 31 July, 2014 as stipulated in several previous resolutions (Resolution 1550 (2003), Resolution 1546 (2004), Resolution 1557 (2004), Resolution 1619 (2005), Resolution 1700 (2006), Resolution 1770 (2007), Resolution 1830 (2008), Resolution 1883 (2009), Resolution 1936 (2010), Resolution 2001 (2011), Resolution 2061 (2012) and Resolution 2107 (2013).)  The resolution signaled its intention to review the original mandate, as stipulated in UNSC resolution 2061 within twelve months. United Nations Security Council Resolution 1441 is a United Nations Security Council resolution adopted unanimously by the United Nations Security Council on 8 November 2002, offering Iraq under Saddam Hussein "a final opportunity to comply with its disarmament obligations" that had been set out in several previous resolutions (Resolutions 660, 661, 678, 686, 687, 688, 707, 715, 986, and 1284). UN Security Council Resolution 748, adopted unanimously on 31 March 1992, after reaffirming Resolution 731 (1992), the UN Security Council decided, under Chapter VII of the United Nations Charter, that the Government of Libya must now comply with requests from investigations relating to the destruction of Pan Am Flight 103 over Lockerbie and UTA Flight 772 over Chad and Niger, calling on Libya to cease all forms of terrorist action and assistance to terrorist groups.  To this end, the Council imposed sanctions on Libya until Libya complied. Chapter VI of the United Nations Charter deals with peaceful settlement of disputes.  It requires countries with disputes that could lead to war to first of all try to seek solutions through peaceful methods such as "negotiation, enquiry, mediation, conciliation, arbitration, judicial settlement, resort to regional agencies or arrangements, or other peaceful means of their own choice."  If these methods of alternative dispute resolution fail, then they must refer it to the UN Security Council.  Under Article 35, any country is allowed to bring a dispute to the attention of the UN Security Council or the General Assembly.  This chapter authorizes the Security Council to issue recommendations but does not give it power to make binding resolutions; those provisions are contained Chapter VII.  Chapter VI is analogous to Articles 13-15 of the Covenant of the League of Nations which provide for arbitration and for submission of matters to the Council that are not submitted to arbitration.  United Nations Security Council Resolution 47 and United Nations Security Council Resolution 242 are two examples of Chapter VI resolutions which remain unimplemented. United Nations Security Council Resolution 85, adopted on July 31, 1950, was the United Nations Security Council resolution which authorised the United Nations Command under General Douglas MacArthur to support the Korean civilian population, and requested that specialized agencies, appropriate subsidiary bodies of the UN and appropriate non-governmental organizations support the UN Command in doing so.

United Nations Security Council Resolution 1747 was a United Nations Security Council resolution that tightened the sanctions imposed on Iran in connection with the Iranian nuclear program.

United Nations Security Council Resolution 66, adopted on December 29, 1948, in response to a report by the Acting Mediator regarding hostilities which broke out in southern Palestine on December 22 despite UN calls for a cease-fire, the Council demanded the immediate implementation of United Nations Security Council Resolution 61.  The Resolution instructs the Acting Mediator to facilitate the complete supervision of the truce by the UN observers.  The Resolution further instructs the committee appointed in UNSC Resolution 61 to meet at Lake Success, New York on January 7 to consider the situation in southern Palestine and to report to the Council on the extent to which governments have or have not complied with UNSC Resolutions 61 and 62.  The Resolution also invited Cuba and Norway to replace the two retiring member of the committee (Belgium and Colombia) on January 1. United Nations Security Council Resolution 41, adopted on February 28, 1948, commended both parties in the Indonesian National Revolution for the recent signing of a truce and attempts to comply with United Nations Security Council Resolution 27.  Repeated the offer of mediation made in United Nations Security Council Resolution 31 and requested the Committee of Good Offices keep them informed as to the progress of political settlement in the Indonesia.
