N.C. Gen. Stat. § 157-8
The mayor may remove a commissioner for inefficiency or neglect of duty or misconduct in office, but only after the commissioner shall have been given a copy of the charges against him (which may be made by the mayor) at least 10 days prior to the hearing thereon and had an opportunity to be heard in person or by counsel.
Any obligee of the authority may file with the mayor written charges that the authority is violating willfully any law of the State or any term, provision or covenant in any contract to which the authority is a party. The mayor shall give each of the commissioners a copy of such charges at least 10 days prior to the hearing thereon and an opportunity to be heard in person or by counsel and shall within 15 days after receipt of such charges remove any commissioners of the authority who shall have been found to have acquiesced in any such willful violation.
A commissioner shall be deemed to have acquiesced in a willful violation by the authority of a law of this State or of any term, provision or covenant contained in a contract to which the authority is a party, if, before a hearing is held on the charges against him, he shall not have filed a written statement with the authority of his objections to, or lack of participation in, such violation.
In the event of the removal of any commissioner, the mayor shall file in the office of the city clerk a record of the proceedings together with the charges made against the commissioners and the findings thereon.
