Any objection to the conduct of a party to an election must be by a prohibited practice complaint filed in accordance with 26 M.R.S.A. §§968, 979- H, 1029 or 1289, as appropriate, and in conformity with Chapter 12 of these Rules. Activities of a party to an election which materially compromise the secret ballot process, effectively disenfranchise eligible voters or otherwise interfere with a free and fair election are grounds for such an objection.
