In furtherance of its clean air campaign, California passed a law that required all non-electric commercial vehicles driving on its roads to purchase and display an annual pass. The pass cost $100 and the proceeds from the sale of the passes went to a fund used to research and implement technology to reduce carbon emissions known to pollute the air. Truckers R Us, a large commercial shipping company incorporated in Pennsylvania, whose trucks would sometimes drive through California and therefore be required to purchase a pass, filed a lawsuit challenging California's law as being unconstitutional in that it violated both the Due Process Clause and the Commerce Clause.
