He served in the government of Cameroon as Minister of the Civil Service from 1990 to 1992 and is currently the President of the Alliance for Democracy and Development (ADD), a minor political party.
[2] Early in his career, Garga held a succession of high-level administrative posts in Cameroon, working as Sub-Director of National Security, Deputy Director of the Ministry of Finance, Secretary-General of the Ministry of the Civil Service, and Finance Director of the National Electricity Company of Cameroon.
[4] Following the April 1984 coup attempt, in which northerners were implicated, Garga was arrested and held at the Kondengui Central Prison.
[2] President Paul Biya appointed Garga to the government as Minister of the Civil Service and the Supreme State Audit in 1990.
[8][9] Garga's ministerial portfolio was then modified on 9 April 1992, when he was appointed as Minister of the Civil Service and Administrative Reform;[4] he thus lost his authority over the Supreme State Audit.
[12] Following the June 2002 parliamentary election, Garga and four other notable northern politicians released a statement in July, in which they alleged electoral fraud and announced the formation of a "resistance front".
[2] Along with other opposition leaders, Garga called for the computerization of the electoral process, saying that it was necessary to "preserve the social peace and guarantee a transparent election".
[16] Biya won the election overwhelmingly, although Garga managed a "respectable" performance in the area of Diamaré, located in Far North Province.
Following the creation of the Mo Ibrahim Prize, which was intended to promote good governance by rewarding retired African leaders with large sums of money, Garga expressed skepticism in an October 2006 interview with BBC Africa.
He was also skeptical that the prize would encourage African leaders to retire, arguing that no amount of money would be sufficient if they did not want to leave power.
[20] On 15 March 2007, President Biya appointed Garga to a three-year term on the Coordination Committee of the National Anti-Corruption Commission.
