Military Service and the Nigerian Civil War
Following his commission, Madaki served actively during the Nigerian Civil War between 1967 and 1970, a conflict that arose after the Eastern Region attempted to secede as the Republic of Biafra. While details of his specific assignments during the war are not widely documented, his service placed him among the generation of officers whose careers were shaped by the conflict and its demands on leadership, strategy, and military administration.
Service in the Special Military Tribunal
Between 1984 and 1985, during the military regime of General Muhammadu Buhari, Colonel Madaki was appointed as a member of the Special Military Tribunal in the Ibadan Zone. These tribunals were tasked with adjudicating cases related to corruption and economic crimes under military rule, operating outside the traditional civil judicial system. Madaki’s role in the tribunal reflected the trust placed in his legal and administrative capabilities, and his service helped enforce military governance policies during a period of national austerity and reform.
Military Governorships
In August 1985, following the coup that brought General Ibrahim Babangida to power, Madaki was appointed Military Governor of Gongola State, a region that now comprises Adamawa and Taraba states. He served in this capacity until August 1986, overseeing administrative duties and implementing federal directives.
Following this, he was briefly appointed Military Governor of Benue State, serving from August to September 1986, before handing over to Major General Ishaya Bakut. His tenure in both states placed him within the broader framework of military governance in Nigeria, which relied on officers to manage state administration, maintain order, and implement national policies.
Legal Education and Career
While stationed in Ibadan, Madaki pursued legal education, earning an LLB degree from the University of Ibadan in 1984. He subsequently attended law school and was called to the Nigerian Bar in 1985. Upon retiring from the army in 1986, Madaki began legal practice in Kaduna, focusing on litigation and legal representation.
His legal career bridged military and civilian governance, demonstrating the role of military officers in shaping post-military legal institutions. Madaki’s expertise in law later positioned him for influential roles in party politics and regulatory administration.
Political and Regulatory Roles
Madaki later became the first National Legal Adviser of the Peoples Democratic Party (PDP), one of Nigeria’s major political parties formed in the late 1990s. In this role, he provided legal guidance to the party during its formative years and participated in ensuring compliance with electoral regulations and internal governance structures.
In 2001, Colonel Madaki was appointed Chairman of the Board of the Securities and Exchange Commission, Nigeria’s primary financial regulatory authority. This role placed him at the forefront of capital market oversight, policy implementation, and institutional governance during a period of economic reform and expansion. His appointment underscored the transition of experienced military officers into civilian leadership positions in the regulatory and political sectors.
