The International Longshoremen's Association refused to unload cargo shipped from the Soviet Union as a way of protesting the Soviet invasion of Afghanistan. Allied International, an importer of Soviet wood products, could not get its wood unloaded when its ship arrived in Boston. Allied sued on the basis of the National Labor Relations Act, claiming the conduct was an unlawful boycott. The union claims no commerce is involved and that federal law does not apply. Can the statute survive a constitutional challenge? Is there a "rational basis" for the statute? What effect does the evidence to the contrary have on the statute's constitutionality?
