4. The rights of the incumbent are, moreover, qualified and controlled by the rights of the bishop on the one hand and of the parishioners on the other. He has a general authority from the bishop to decide as to allowing or disallowing the erection in the churchyard of tombstones with inscriptions, not being of an unusual character in respect of size or otherwise, as well as glass shades for wreaths and other additions to the contents of the churchyard.[329] But any person interested may appeal against his decision to the bishop's court, which has power to determine the matter, subject to appeal to the higher tribunals.[330] He cannot, however, authorise the erection of monuments or tablets in the church itself, nor monuments of abnormal size in the churchyard. These, as well as other additions to or alterations in the church or churchyard, require the sanction of a faculty either from the bishop's consistory court or, if there refused, from the provincial court or the Judicial Committee of the Privy Council. A faculty for the purpose will, in proper cases, be granted on the application of the incumbent and churchwardens supported by a resolution of the vestry.[331] If there is a rector impropriate, his consent will be necessary to any proposed change in the chancel. As already noticed (Ch. VII. § 1 above), the incumbent cannot validly, on his own authority, sell grave spaces in perpetuity in the churchyard; and a faculty will not be granted for a vault or space for exclusive burial unless it is clearly improbable that it will inconveniently diminish the available ground for the burial of the parishioners.[332] It is an offence on the part of any one to remove earth and bones from the churchyard[333] or to desecrate it in any other way; but a faculty will in a proper case be granted for diverting the course of an ancient footpath through a churchyard when necessary for the enlargement of the church;[334] and for throwing a portion of a churchyard, which is not required for interments, into a highway.[335] A wall of a churchyard which has been wilfully pulled down does not require a faculty for its restoration.[336] A faculty has been granted to secure for ninety-nine years an easement of light and air to the lower windows of an adjoining house through the railings of a churchyard, on payment of an annual rent of £22 to the rector for the time being.[337] Where a churchyard or other burial ground has been closed or is no longer used for burials, a faculty may be obtained for laying it out as a garden with footpaths, and removing the tombstones and placing them against the walls of the church or churchyard;[338] but the erection upon it of any building, except for the purpose of enlarging a church, chapel, or other place of worship, is unlawful, and no faculty can be granted for it.[339]
