 Any pious Muslim nominated by other Muslims could be an eligible caliph.Additionally, Kharijites believed that obedience to the caliph is binding as long as he is managing the affairs with justice and consultation, but if he deviates, then it becomes obligatory to confront him, demote him and even kill him.Ibadiyya has some common beliefs overlapping with Ashari, Mu'tazila, Sunni and some Shi'ites.
