18- 553 C.M.R. ch. 20, § II-10.0
In purchasing a Play, or attempting to claim a prize, purchasers and prize claimants agree to comply with and abide by all applicable Maine laws, rules promulgated, procedures, and decisions of the Selling Lottery where the Play was purchased, and by directives and determinations of the director of that Party Lottery.
A prize claimant agrees, as its sole and exclusive remedy that claims arising out of a Powerball Play can only be pursued against the Selling Lottery which issued the Play. Litigation, if any, shall only be maintained within the jurisdiction in which the Powerball Play was purchased and only against the Selling Lottery that issued the Play. No claim shall be made against any other Participating Lottery or against the MUSL
Nothing in these Rules shall be construed as a waiver of any defense or claim the Selling Lottery which issued the Play, any other Participating Lottery or MUSL may have in any litigation, including in the event a player or prize claimant pursues litigation against the Selling Lottery, any other Participating Lottery or MUSL, or their respective officers, directors or employees.
All decisions made by a Selling Lottery, including the declaration of prizes and the payment thereof and the interpretation of Powerball Rules, shall be final and binding on all Play purchasers and on every person making a prize claim in respect thereof, but only in the jurisdiction where the Powerball Play was issued.
Unless the laws, rules, regulations, procedures, and decisions of the Lottery which issued the Play provide otherwise, no prize shall be paid upon a Play purchased, claimed or sold in violation of these Rules or the laws, rules, regulations, procedures, and decisions of that Selling Lottery; any such prize claimed but unpaid shall constitute an unclaimed prize under these Rules and the laws, rules, regulations, procedures, and decisions of that Selling Lottery.
