(a) Each eligible domestic manufacturer and importer of softwood lumber shall be entitled to cast only one ballot in the referendum. However, each domestic manufacturer in a landlord/tenant relationship or a divided ownership arrangement involving totally independent entities cooperating only to manufacture softwood lumber, in which more than one of the parties is a domestic manufacturer or importer, shall be entitled to cast one ballot in the referendum covering only such domestic manufacturer or importer's share of ownership.

(b) Proxy voting is not authorized, but an officer or employee of an eligible corporate domestic manufacturer or importer, or an administrator, executor, or trustee of an eligible entity may cast a ballot on behalf of such entity. Any individual so voting in a referendum shall certify that such individual is an officer or employee of the eligible entity, or an administrator, executive, or trustee of an eligible entity and that such individual has the authority to take such action. Upon request of the referendum agent, the individual shall submit adequate evidence of such authority.

(c) A single entity who domestically manufactures and imports softwood lumber may cast one vote in the referendum.

(d) All ballots are to be cast by mail or other means, as instructed by the Department.
