The considered decision of the court was, that it was not an offence against the Common Law of England to keep a school. If an offence had been committed, it was an offence against ecclesiastical law, and that consequently the remedy was to be found in the ecclesiastical courts.[291] The significance of this case was that the monopoly of school keeping was partly broken down. Henceforth, anyone who did not fear ecclesiastical censure and excommunication might keep school, if he so desired. The practical effect of the decision was slight since, as we have seen,[292] the monopoly right of keeping school was granted to Eton College thirty years later. A problem in connection with this question of monopoly arose in Lincoln in 1407-9. There were two recognised schools in Lincoln; the general grammar school attended by the children of the citizens, and to which the choristers formerly went for their instruction in Latin, and the school of the choristers. In course of time, the choristers' school ceased to confine itself to the study of music and added Latin to its curriculum. For some reason or other, this school also attracted outside scholars. The Mayor and Corporation, as representatives of the citizens of Lincoln, objected;[293] ultimately the matter was settled by a compromise; the teachers of the choristers were to be allowed "to teach grammar to the choristers and to the commoners with them, also to the relations of the canons and vicars of the church or those living at their expense and charity or dwelling in their family," provided that a nominal acknowledgement of the rights of the master of the City Grammar School was made each term.[294] Another problem arose out of the competing claims of the master of song and of the master of grammar. The master of song apparently maintained that he was as much an official master as the master of grammar, and probably considered himself quite as competent as his colleague to give lessons in Latin. This problem seems to have been particularly acute at Warwick, and so the authorities of the collegiate church made careful enquiries as to the ancient customs on the matter, and ultimately found that the Latin master alone possessed the right of taking classes in Latin. As a concession, they allowed the master of song to take paying pupils in the "first letters" and the psalter.[295]
