[2] In a letter dated 25 April 2000, addressed to the President of the Security Council, Secretary-General Kofi Annan nominated five international observers, one each from the European Union, the League of Arab States, and jointly from the Organization of African Unity and the Non-Aligned Movement, and two from the International Progress Organization, a Vienna-based NGO in consultative status with the United Nations, among them the organisation's president, Hans Köchler, professor at the University of Innsbruck, Austria.
[3] Hans Köchler was the only international observer to submit comprehensive reports on the Lockerbie trial and appeal proceedings to the Secretary-General of the United Nations who, in turn, forwarded them to the Registrar of the Scottish Court in the Netherlands.
[7] On 4 July 2007, Köchler wrote to Scottish first minister, Alex Salmond, British foreign secretary, David Miliband, home secretary, Jacqui Smith and minister for Africa, Asia and the UN, Mark Malloch Brown, reiterating his call for a public inquiry into the Lockerbie case and insisting that UN-appointed legal experts (from countries other than the UK, US and Libya) should be involved in such an inquiry.
[8] In the June 2008 edition of the Scottish lawyers' magazine The Firm, Köchler referred to the 'totalitarian' nature of the second Lockerbie appeal process saying it "bears the hallmarks of an 'intelligence operation'.
On 18 September 2008, he delivered a keynote speech on the "Lockerbie Trial and the Rule of Law" organised by The Firm magazine which was held at the Glasgow Hilton Hotel.
