Wanjala was appointed to the apex court in 2011 by the late President Mwai Kibaki alongside current serving justices Mohamed Ibrahim and Njoki Ndung’u.
Unknown to many, Wanjala has a rich background in education having been a lecturer at the University of Nairobi (UoN) School of Law for nearly two decades.
He left the teaching profession in 2004 before he was appointed as one of the directors of the defunct Kenya Anti-Corruption Commission (KACC) now known as the Ethics and Anti-Corruption Commission (EACC).
His educational background contributed to his appointment as the director of Kenya Judiciary Academy (KJA) – which is tasked with the training of judges and judicial officers in the country.
Additionally, he serves as the judicial representative to the Council of Legal Education- a position he has held since 2019.
Just as his exemplary career in education, the judge is a distinguished academician and holds a Doctorate in Law from the University of Ghent in Belgium.
Justice Wanjala is a holder of a Bachelor of Laws (LL.B, Hons.) from the University of Nairobi, a Post Graduate Diploma in Law from the Kenya School of Law, a Master of Laws (LL.M) from Columbia University, New York, ” his Supreme Court bio reads.
Apart from his role at the Supreme Court, Wanjala has served in other judicial institutions which have been credited for promoting political and social reforms in the country.
In particular, he served at the Centre for Law and Research International (CLARION) which is the body that pioneered civil education in the country.
He is also a member of the Advisory Board of Columbia Global Centers – Nairobi, Kenya, which is one of the nine World-Wide Regional hubs established by Columbia University to enhance research and collaboration for the benefit of humanity,” the Judiciary states on its website.
His works have over the years seen him get accolades. Wanjala is a holder of the Chief of the Order of the Burning Spear (CBS) which was conferred to him in 2012 by President Kibaki.
