Constitutional Court president Daniele Darlan, a 70-year-old lawyer, jurist and former university professor, says she's not stepping down.
Darlan, appointed in 2017 to a seven year term, says she intends to fulfill it despite pressures to leave.
Observers note that along with her insistence to stay, the Constitutional Court has clearly indicated its willingness to prevent President Faustin-Archange Touadera from staying in office past his two terms.
The Court last month annulled a commission's proposal that would let Touadera, 65, stand for a third presidential poll in line with a trend in some parts of Africa that opponents see as creeping autocracy.
Touadera's allies in May called for a change in the constitutional clause saying presidents can only run twice, arguing this was uncommon around neighboring countries.
Several other African presidents, including in Rwanda, Congo Republic, Ivory Coast and Guinea, have pushed through constitutional and other legal changes in recent years to allow themselves to stay in office.
The next vote in Central African Republic is due in 2025.
