Canon 106

1. The synod of bishops of the patriarchal Church must be convoked whenever: (1) matters are to be decided which belong to

the exclusive competence of the synod of bishops of the patriarchal Church or which, in order to be done, require the consent of

the synod; (2) the patriarch, with the consent of the permanent

synod, judges it necessary; (3) at least one-third of the members request it for a given matter, with due regard always for

the rights of patriarchs, bishops and other persons established

by common law. 2. Moreover the synod of bishops of the patriarchal Church must be convoked at the established times, even

annually, if particular law determines it.
