You cannot nulify an election based on outlier errors especially if they don't make a difference in the 50+1.
IEBC generated an error report and all these things should be documented there. Once a quantitative analysis is done and the errors isolated, I assume they will try to see if those errors will affect the final tally. If not, I don't see how they can nulify.
After all there is no election that is perfect where people are involved, whether through gross negligence or active electoral malpractice.
