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

(b) Proxy voting is not authorized, but an officer or employee of an eligible corporate domestic producer or importer, or an administrator, executor, or trustee or 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) All ballots are to be cast by mail as instructed by the Department.

(d) Eligible domestic producers or eligible importers may be asked to provide proof of sales or acreage as proof of eligibility to vote in any referendum.
