(plaintiff, MO Attorney General, has filed suit against defendant, CA Attorney General, seeking declaratory and injunctive relief, costs and fees, associated with blocking enforcement of CA's Proposition 2 and A.B. 1437 which will increase size of egg-laying hen enclosures and decrease flock densities for CA egg producers and egg producers in other states desiring to sell eggs in CA; suit notes that CA consumers bought one-third of all eggs produced in MO in 2013 and CA requirement will substantially increase cost of MO egg production if egg producers continue to sell eggs in CA, which will also make eggs too expensive to sell in other states; suit notes that if MO producers choose to not participate in CA market, other markets will have surplus eggs and egg prices will fall which could force some producers out of business; suit claims that CA provision violates Commerce Clause by "conditioning the flow of goods across its state lines on the method of their production"; in the alternative, suit alleges federal preemption via 21 U.S.C. Sec. 1052(b); suit filed after the the Farm Bill conferees rejected House Farm Bill provision that would have barred the conduct that CA has engaged in).
