The Wisconsin Supreme Court found that the legislature's delegation to the state agency was reasonable. The delegation set reasonable limits on the scope of the agency's power in crafting the specific prohibitions of chain distributor systems. The legislature may designate powers to state agencies, subject to limitations and definitions of that power. The Department of Agriculture did in fact stay within its delegated authority in crafting the rules prohibiting chain distributor systems, making the rule constitutional.
