The Dominican Association of Cement Producers has taken Presidential Decree 36-02 to the Supreme Court, on grounds that the decree grants preferential market conditions to the Cemento Andino company that is installing a cement factory in the Parque Industrial Minero de Pedernales. The cement producers say that the decree issued 10 January 2002 violates the Constitution by exempting the company from paying taxes, which they say equates to unfair competition with the other producers. The cement producers say that the decree is also unjust because the contract with the company was not sent to the National Congress.
