Prof Oloka-Onyango's Professorial Inaugural Lecture, entitled Ghosts & the Law, contained a detailed analysis of the origins, manifestations and intricacies of the Political Question Doctrine in Uganda and its closely related co-concept of Public Interest Litigation and together, their impact on Constitutionalism, the Doctrine of Separation of Powers, enforcement of fundamental Human rights, judicial independence, the phenomenon of "Presidentialism" and other aspects of modern state life. Within this lecture, he also extensively reviewed the historic precedent in Uganda v Commissioner of Prisons, Ex Parte Matovu and its effects on Ugandan jurisprudence to-date. On May 5, 2016, he took lead when he made the inaugural staff lecture at the Makerere University School of Law, presenting a paper entitled "Enter the Dragon, Exit a Myth: The Contested Candidacy of John Patrick Amama Mbabazi". On May 9, 2016, Prof Oloka-Onyango and 8 other law dons from Makerere University School of Law successfully filed an application before the Supreme Court of Uganda for leave to intervene in Uganda's 2017 Presidential election petition, Amama Mbabazi v. Yoweri Museveni & the Electoral Commission, as Amici Curiae. This became the first time in Ugandan electoral history that the Supreme Court heard and granted an application for such leave. The nine law dons were; Oloka-Onyango, Sylvia Tamale, Christopher Mbazira, Ronald Naluwairo, Rose Nakayi, Busingye Kabumba, Daniel Ruhwheza, Kakungulu Mayambala and Daniel Ngabirano. As part of their submission, the law dons recommended to the Court the use of structural interdicts or supervisory injunctions to deal with the persistent disregard of its recommendations by the Electoral Commission and the State in matters of the electoral process. In its ruling, the Court stated that; "We are satisfied that the applicants have proven record in the area of Human Rights, Constitutionalism and Good Governance. They are highly experienced and widely researched legal scholars in these and related matters as evidenced by the attached curricula vitae."''
