Pope Gregory X writes to the bishop of Dunblane noting the petition by the dean and chapter of Glasgow that William, of good memory, bishop of Glasgow, being attentive to the liberties and customs of the church of Salisbury, that they may be preserved in the church of Glasgow, had established the said liberties and customs with the assent of the late Walter, dean, and chapter of Glasgow, both concerning the enforcement of offices obtained by personas, dignities and prebends and celebrating divine office in that place, and towards others, that those liberties and customs might be observed in perpetuity in the said church of Glasgow. Afterwards, by the supplications of the dean and chapter, the pope had directed that this be confirmed. Master William of Lindsay, acting for the archdeacon of Glasgow, and Master William Salsarius, acting for [the archdeacon’s?] official, presumed to impede the observation of those liberties and customs against justice. Whereby the dean and chapter beseeched the pope that the said Masters William of Lindsay and William Salsarius be restrained from impediments of this sort. The pope thus commands him to call together those who may be called and to hear and then to propose what shall be just, without appeal, making what is decreed to be observed through ecclesiastical censure. If the witnesses named shall have withdrawn out of favour, hatred or fear, they shall compel them by the same censure, without appeal, to provide testimony of the truth.
