Del. Code tit. 15 § 5309
If it is apparent to the Court sitting as board of canvass that any interference with the performance of its duties will be attempted by military force, or if, after it has met, any such interference is attempted, it may meet at any other place within its county to perform its duties. And further, if any member of the Court, or any such inspector created by virtue of this title, or any inspector of election, is prevented, by reason of such interference from attending the meeting of the Court, or if the Court, being met, shall be prevented by such interference from performing the duties incumbent on it, the Court shall adjourn to meet at some other time and other place, if necessary, to perform its duties under the laws of this State, and so adjourn from time to time until such duties can be performed. The duty of attendance upon the Court on the part of such an inspector created by authority of this chapter, and the penalties upon such inspector for not appearing shall be the same as in the case of the inspectors regularly elected or appointed according to law.
