Without proper implementation by state officials even the best e-voting laws are ineffective. In November 2005 Diebold Election Systems filed suit against the North Carolina Board of Elections to avoid a law requiring vendors to let state officials examine machines' source code for security vulnerabilities. EFF intervened in the case getting the complaint dismissed. When election officials later agreed to certify Diebold anyway in violation of the law EFF filed a legal challenge. Diebold subsequently withdrew its e-voting machines from North Carolina elections.
