Premise: On March 11, 1996, Mickey Kantor, the American trade secretary, announced that he was filing a complaint with the World Trade Organization to protest, first, the 80% excise tax on split run magazines under Bill C-103, second, the lower postal rates granted Canadian publications, third, the postal subsidy and, fourth, tariff 9958 making it illegal to import split runs into Canada.
Hypothesis: Canadian publications was a concern for Mickey Kantor as American trade secretary and he filed multiple complaints concerning such even though he was one of few who considered them to be a real obstacle to fair trade.
