Equal Protection Clause (Article I, Section 19): “No person shall be denied the equal protection of the laws.” “these clauses provide significant constraints against governmental conduct that disfavors certain groups of voters or creates barriers to the free ascertainment and expression of the will of the People…” (Common Cause v. Lewis 2019)

Free Speech Clause (Article I, Section 14): “Freedom of speech and of the press are two of the great bulwarks of liberty and therefore shall never be restrained…” “[T]he North Carolina Constitution affords a direct cause of action for damages against government officers in their official capacity for speech violations, even though federal law does not” (Common Cause v. Lewis 2019)

Free Election Clause (Article I, Section 10): “All elections shall be free.” Common Cause v. Lewis (2019): “Elections are not free when partisan actors have tainted future elections by specifically and systematically designing the contours of the election districts for partisan purposes and a desire to preserve power.”
