North Carolina General Statutes Chapter 138A. State Government Ethics Act § 138A-37. Legislator participation in legislative actions

(a) Except as permitted under G.S. 138A-38, no legislator shall participate in a legislative action if the legislator knows the legislator or a person with which the legislator is associated may incur a reasonably foreseeable financial benefit from the action, and if after considering whether the legislator's judgment would be substantially influenced by the financial benefit and considering the need for the legislator's particular contribution, including special knowledge of the subject matter to the effective functioning of the legislature, the legislator concludes that an actual financial benefit does exist which would impair the legislator's independence of judgment.

(b) The legislator shall submit in writing to the principal clerk of the house of which the legislator is a member the reasons for the abstention from participation in the legislative matter.

(c) If the legislator has a material doubt as to whether the legislator should act, the legislator may submit the question for an advisory opinion to the State Ethics Commission in accordance with G.S. 138A-13 or the Legislative Ethics Committee in accordance with G.S. 120-104.
