Under the NVRA, a change of residence would require a set procedure to be followed before a name could be removed on this ground. 42 U.S.C. § 1973gg-6(c) & (d). The procedure would require either a verification from the registrant of a move within the jurisdiction or a confirmation of a move outside the jurisdiction. If the registrant fails to respond, there are more procedures to be followed before a name could be removed. As you are aware, compliance with the NVRA may necessitate changes to Title 15.
Along with changes to the State statutes addressing proper removal of a voter's registration, a new set of regulations to comply with the federal statutes may be necessary. The new regulations could be developed by the State Election Commissioner, pursuant to 15 Del. C. §302(4), as such regulations would be "reasonable rules and regulations with respect to the functions of his office and with respect to the manner of making entries in registration and election records to be followed by each department and all registration and election officers." By developing statewide regulations for the removal of registrations from the voter rolls, the State Election Commissioner can see that the activity is uniform, nondiscriminatory and in compliance with the Voting Rights Act of 1965 as required in 42 U.S.C. §1973gg-6(b).
