In 1988 following the decision in "Cole v Whitfield", which was notable also for the Court's willingness to use the transcripts of the Convention debates as an aid to interpretation, the Court unanimously decided that what the section prohibited, in relation to interstate trade and commerce, were only "discriminatory burdens of a protectionist kind". That is, the section did no more than guarantee "free trade" (in the conventional sense) among the States. But in relation to "intercourse" (i.e. personal movement between States), the Court suggested that the scope of the guarantee would be much wider, and may even, in relation to some forms of such intercourse, be truly absolute.
