California plans to set space standards for hens and housing standards for pigs.
The National Pork Producers Council said the proposals lack any scientific, technical or agricultural basis and would unduly interfere with inter-state trade.
California accounts for about 15 per cent of the U.S. pork market.
The court ruled that the farmers "have failed to demonstrate that there is a substantial burden on interstate commerce.”
Look out, folks! Political correctness happens first in California often sweeps across North America.
