Use of a single nomination from a nominating committee and refusal to open up nominations.

[GoodGNUS]

The Manual of the Church of the Nazarene stipulates that District Assemblies "elect, by two-thirds favorable vote, by ballot, an elder to the office of district superintendent..." Traditionally this has been done by a nominating ballot, but in the last decade the international board has insisted that a district leadership board go through a process and recommend a single candidate. They then highly skew the procedures to discourage/prohibit additional nominees.
The district board acted as a nominating committee. 46:18 clearly states requirements for further nominations from the floor following their report. The presiding officer stated that the assembly could vote "to hear the committee report" or not, and only if that motion was defeated, open up nominations from the floor. I as a delegate objected one on one to the presiding officer and to the assembly. The presiding officer simply said "We've looked into this and have been assured it is legal."
Does RONR require that, following a report of the nominating committee, the chair call for further nominations from the floor?
