16 U.S. Code § 7002 - United States representation on joint management committee
Each representative appointed under paragraph (1) shall be appointed for a term not to exceed 4 years, except that, of the initial appointments, 2 representatives shall be appointed for terms of 2 years. Any individual appointed to fill a vacancy occurring prior to the expiration of the term of office of that individual’s predecessor shall be appointed for the remainder of that term. A representative may be appointed for a term of less than 4 years if such term is necessary to ensure that the term of office of not more than 2 representatives will expire in any single year. An individual appointed to serve as a representative is eligible for reappointment.
The Secretary, in consultation with the Secretary of State, may designate alternate representatives of the United States to serve on the joint management committee. An alternative representative may exercise, at any meeting of the committee, all the powers and duties of a representative in the absence of a duly designated representative for whatever reason.
