A major voice in the state Legislature is speaking out against changing the controversial Livestock Marketing Law, placing in jeopardy an agreement on a change worked out for the special session. Governor Bob Holden had insisted a concensus be reached on changing the law before he would include it in the special session. House Speaker Jim Kreider of Nixa tells the Missourinet a compromise worked out among some farm groups with some lawmakers might not hold up. Farm groups have pressed for a change, claiming the law has chased big packers from Missouri and hurt livestock producers. Kreider counters there is no evidence of that and insists the law protects small producers. He opposes a change.
