In a case decided last month, Bulgarian Orthodox Old Calendar Church v. Bulgaria, (ECHR, April 21, 2021), the European Court of Human Rights, in a Chamber Judgment, held that Bulgaria had violated Article 9 of the European Convention on Human Rights when it refused to register a church adhering to the Old Calendarist variant of Eastern Orthodoxy. Bulgarian courts relied on a provision in the Religious Denominations Act of 2002 providing that persons who had seceded from a registered religious institution before the Act’s entry into force in breach of that institution’s internal rules could not use the name of that institution. The European Court said in part:
62. Requiring a religious organisation seeking registration to take on a name which is not liable to mislead believers and the general public ... can in principle be seen as a justified limitation on its right freely to choose its name.... But the names of the applicant church and of the Bulgarian Orthodox Church were not identical, the applicant church’s name being sufficiently distinguished by the words “Old Calendar”. It is well known that Old Calendarist churches, which first appeared in the 1920s, when some Eastern Orthodox churches switched from the Julian Calendar to the Revised Julian Calendar, are distinct from those Eastern Orthodox churches.... Moreover, nothing suggests that the applicant church wished to identify itself with the Bulgarian Orthodox Church....
63. In so far as the Government argued that the overlap between the beliefs and practices of the applicant church and of the Bulgarian Orthodox Church was also a bar to the applicant church’s registration...- it should be noted that the assessment of whether or not religious beliefs are identical is not a matter for the State authorities, but for the religious communities themselves.... Pluralism, which is the basic fabric of democracy, is incompatible with State action compelling a religious community to unite under a single leadership....
64. The refusal to register the applicant church was therefore not “necessary in a democratic society”. It follows that there has been a breach of Article 9 of the Convention read in the light of Article 11.

In a second case decided the same day, Independent Orthodox Church v. Bulgaria, (ECHR April 21, 2021), the same section of the European Court held that Bulgaria violated Article 9 of the Convention when it refused to recognize a new church because its name and beliefs were the same as those of the existing Bulgarian Orthodox Church. The Court commented:
[T]he State does not need to ensure that religious communities remain under a unified leadership.... Even if the creation of the applicant church was ... prompted by a division within the Bulgarian Orthodox Church, this fact does not alter that.... Nor does the fact that the Bulgarian Orthodox Church’s unity is considered of the utmost importance for its adherents and for Bulgarian society in general.
