The fact is that the Holy Synod unanimously took a grave decision to discipline its presiding bishop for not acting properly.
You asked for chapter and verse and you will get it. This is from the Minutes of the Santa Fe Meeting that was published after Metropolitan Jonah said he was not put on a leave of absence and did not act as if he was on such a leave.

The Holy Synod’s Concern for the Health of His Beatitude, Jonah
The Holy Synod discussed matters affecting the primatial service of His Beatitude, Metropolitan JONAH. Holy Synod members affirmed their love and obedience to the Metropolitan and reminded him that love and obedience are also reciprocal between the Metropolitan and the Holy Synod. There must be mutual obedience.
Metropolitan JONAH was asked to absent himself from the meeting.
Metropolitan JONAH returned to the meeting.
The Holy Synod took the following actions and reviewed them with His Beatitude:
2. The Holy Synod expressed concern for the Metropolitan’s health. Once again they affirmed their love and concern for him and their earnest desire to see him succeed. After further discussion, the Holy Synod determined that a sixty day Leave of Absence for His Beatitude would be beneficial. Metropolitan Jonah accepted to do so. The Synod asked him to request to do so, as it would be better seen that he acknowledged the need for this. Metropolitan JONAH then requested a Leave Of Absence for not less than 60 days during which time he would see a physician and devote himself to his own spiritual and physical health without concern for the burdens of the primatial office. This could include a time of retreat at a monastery. His Grace Bishop Benjamin asked if he was ready to make this decision or if he needed additional time and the Metropolitan said he did not need more time to make the decision.
3. The Holy Synod appointed Archbishop NATHANIEL as Administrator of the OCA for the length of His Beatitude’s leave.
4. The Holy Synod appointed Bishop MELCHISEDEK as interim Chancellor.
5. The Holy Synod relieved His Beatitude, Metropolitan JONAH from his responsibilities as Locum Tenens of the Diocese of the South and appointed Bishop NIKON Locum Tenens of the Diocese of the South with Bishop MARK continuing as administrator.
6. The Holy Synod relieved His Beatitude, Metropolitan JONAH from his responsibilities as Locum Tenens of the Diocese of Midwest and appointed Bishop TIKHON as Locum Tenens of the diocese of the Midwest with Archimandrite MATTHIAS continuing as administrator
Bishop BENJAMIN conveyed to His Beatitude, Metropolitan JONAH, the above decisions of the Holy Synod. He noted that these decisions were made out of love for His Beatitude and out of concern for the spiritual and physical health of the Primate.
The members of the Holy Synod emphasized that it was their desire for His Beatitude to sincerely take this time to address issues of his well‐being so that he could most effectively fulfill his responsibilities as Primate of the Church.
Metropolitan JONAH thanked the brothers for their concern and acknowledged that a leave of absence would be beneficial and noted that he had not had much time off since his election as Primate.
Bishop TIKHON asked His Beatitude if he needed any time to reflect upon these matters.
Metropolitan JONAH declined and confirmed that he would abide by the counsel of his brothers
A. The Holy Synod accepted the request of Metropolitan JONAH for a leave of absence for 60 days.
Thursday, February 24, 2011
The Holy Synod reviewed the decisions from the minutes from the previous days.
Bishop TIKHON presented a draft of the Press Release.Metropolitan JONAH inquired about several upcoming events which he had been scheduled to participate in.
The Holy Synod recommended that it would be best for His Beatitude to begin his leave of absence immediately and allow the Administrator, the Interim Chancellor and the members of the Holy Synod to assume the responsibility for those events
Metropolitan JONAH agreed to this recommendation
