Mayor Adams offered an endorsement Tuesday of Board of Correction Chairman Dwayne Sampson after five board members staged something of a palace coup and blocked Sampson’s choice for a new director.

Saying he was not fully aware of Monday’s dramatic emergency session of the board, Adams said he appoints boards and then steps back.

“Mr. Sampson is bringing a level of experience on how to run the board, and they’re going to go through their moments.”

“He has to navigate that. The board has to navigate that,” Adams said.

The Board of Correction monitors and sets rules for the Department of Correction’s treatment of detainees at Rikers Island and other city jails.

On Monday, the quintet of board members met in a hastily called emergency session and tapped Jasmine Georges-Yilla as interim executive director, denying Sampson his unilateral choice for the post.

The group also changed rules so Sampson could not unilaterally knock members off committees — as happened last month when he removed Bobby Cohen and Jackie Sherman from the committee that investigates deaths and replaced them with two Correction Department loyalists.

Sampson did not attend the meeting and has said nothing since his agenda was upended.

Joseph Ramos and Jacqueline Pitts, the two board members allied with the administration, also did not attend the meeting and have not commented.

“We must be willing to sit in a room — there are going to be moments of debates, moments of disagreements, moments of very heated conversation — but it’s healthy. That’s what our society is about,” Adams added.

The drama started early Monday when Sampson sent a two-page letter to Board of Correction staff announcing his pick for director. In that letter, he also said he was taking personal control of all agency communications.

“I will have the policy and communications unit report directly to me, effective immediately,” Sampson wrote. “Given my intimate knowledge of the board’s needs ... I am best-suited to provide targeted continuous guidance to the unit.”

But following Monday’s meeting, it was the five other board members — not Sampson — who wrote the statement to the public released early Tuesday.

“These steps were necessary to affirm that the New York City Charter vests authority and responsibility in the board as a whole, as opposed to a single member of the board,” the statement said.

Sampson did not respond to an email Tuesday. The agency also did not respond.
