President Museveni has appointed Justices Christopher Madrama Izama, Stephen Musota and Elizabeth Musoke to the Supreme Court.
The Supreme Court currently has 10 justices, with a quorum of seven needed to determine constitutional appeals.
The appointment of the three means the bench will now have 13 justices
In the Tuesday morning statement from State House, the presidential press team said Museveni had also appointed his lawyer John Oscar Kihika as Court of Appeal judge.
Kihika has represented President Museveni in several electoral petitions while working a legal director at the ruling National Resistance Movement (NRM) and a senior partner at Byenkya, Kihika & Co Advocates, a private law firm.
“In the exercise of the powers vested in the president by Article 142 (1) of the 1995 constitution, I have, acting on the advice of the Judicial Service Commission, appointed persons listed as Justices of the Supreme Court and Court of Appeal, respectively,” Mr Museveni said in the statement dated October 31 released on Tuesday morning.
