In brief
Overview
In 2018, North Carolina amended its Constitution to require photographic identification for in‑person voting.
According to NAACP, the NAACP alleged that S.B. 824, the voter‑ID law, offends the Federal Constitution.
The District Court denied the legislative leaders’ motion to intervene and stayed the case pending Supreme Court review.
The Supreme Court held that a presumption of adequate representation is inappropriate when a duly authorized state agent seeks to intervene to defend a state law.
Justice Sotomayor dissented, arguing that the General Assembly’s authority to defend duly enacted state statutes should be respected.
Background and question before the Court
What each side argues
Petitioners (Legislative Leaders)
According to Legislative leaders, they argue that without their participation, important state interests would not be adequately represented, especially given the Governor’s opposition to S.B. 824.
NAACP
According to NAACP, they argue that Rule 24(a)(2) permits intervention only by “new” parties, and the legislative leaders are already “existing” parties, so intervention should be denied.
According to NAACP, they warn that allowing the legislative leaders to intervene could make trial management impossible.
State (Attorney General / Board)
According to David H. Thompson, north Carolina law designates the state as a necessary party and the petitioners as agents of the state in actions challenging state statutes; they were denied intervention in federal court.
According to David H. Thompson, federal Rule of Civil Procedure 24(b)(2) reflects the interest in administering a law, not created by state law.
According to MR. THOMPSON, states can create interests, as shown by Rule 24’s discussion of property and contracts, which are traditionally matters of state law.
