Canada backed down. But if citizens of Canada or the U.S. compiled overwhelming evidence that manganese additives should be removed from gasoline and their governments refused to act, they could not go to a trade panel to ask that such a ban be enacted. Fifth, the WTO allows nations to enact laws that are weaker than a global standard but not stronger. This is the opposite of how many US federal laws operate. For example, there is a federal minimum wage which acts as a floor, not a ceiling.
Individual states can set their own minimum wages higher.
Many environmental laws operate in the same fashion. Sixth, the new planetary constitution includes no Bill of Rights. Our own Constitution could not have been ratified without such a section, which includes in the First Amendment, the right to petition governmenet for redress of grievances. Seventh, the WTO offers no democratic process for change. It can be amended, but only from within.
