Why did the African Union suspend the Central African Republic after Seleka took power?

The African Union (AU) suspended the Central African Republic from the organization following the Seleka rebel coalition's seizure of the capital, Bangui, on March 24, 2013, and their subsequent claim of control over the government.1

This action was part of a widespread condemnation by the international community regarding the unconstitutional manner in which the rebel group took power and ousted the sitting president, François Bozizé. In addition to the suspension, the AU imposed sanctions on the rebel leaders. The suspension remained in place until 2016, when the AU cited progress in restoring constitutional order following the election of Faustin-Archange Touadéra.1
