1. Temple president can not be removed whimsically by the GBC. It neccesitates for the Temple members to decide that.
2. The commissioners (GBC) will serve for a period of 3 years, and they may be re-elected at the end of this period.
Srila Prabhupada left a thorough management structure of governance in ISKCON. Not only that he himself applied it as the following letters show:
74-09-29. Letter: Mukunda:
Regarding the election of President, a president can only be changed by vote. If no vote was taken, then the president cannot be changed. Neither Hamsaduta can change the president whimsically or can anybody else change the president. According the "Direction of Management" the GBC cannot change the President but only by vote can it be done. The GBC's business is to see that the President and the members are doing nicely, following the regulative principles, and chanting 16 rounds and that other things are going on nicely.

N.B. Regarding replacing Abhirama and Damodara I refer to the "Direction of Management" as follows: "Removal of a Temple President by GBC requires support by the local Temple members." Therefore you should take a vote of the Temple members and do the needful. A. C. B.S.

Regarding Abhirama, in your letter you mention that in Miami it is so important center, 65 devotees, growing each day, ideal location. So Abhirama, has done this. He has done much service. He cannot be removed whimsically. Sex disturbance is the permanent disease of the Western people. Anyway I have already written you that the local members must agree for him to be removed by you, according to the "Direction of Management."
