NORMAN, Okla. Liquor wholesalers who object to a state statute allowing winemakers to sell their products directly to liquor stores and restaurants asked a federal judge today to throw out the voter-approved law.

Attorney Robert McCampbell said the law puts out-of-state wine producers at an unconstitutional disadvantage compared to in-state producers. 

Assistant attorney general Sherry Todd said the law should be preserved and that some small Oklahoma winemakers would be forced out of business if it were invalidated.
