The largest farm group in North Dakota will decide next week whether to seek a statewide referendum against the so-called ham-and-cheese exemptions to a state law against corporate farming, says the Associated Press. Gov. Jack Dalrymple has signed legislation that exempts hog and dairy farms from the Depression-era law. Backers say the exemptions will revitalize livestock agriculture in the state. Critics say it’s an invitation for huge out-of-state companies to trample on North Dakotans. The state agriculture commissioner says a ruckus over the law could lead to a court ruling that invalidates it.
