The Maine supreme court is hearing arguments in the case of a Blue Hill farmer who ignored state law and followed a local ordinance allowing farmers to sell directly to consumers.
Dan Brown was issued a civil summons in 2011 for selling milk and other items without state licenses from his farm stand and at farmers' markets.
Blue Hill is one of several towns where voters passed ordinances allowing small-scale farmers to bypass state and federal regulations on foods sold directly to consumers. The attorney general's office says local laws were pre-empted by state and federal laws, thereby making them invalid.
A group of Maine farmers and activists plan to rally Tuesday at the Cumberland County Courthouse.
