Father Hugo Valdemar says in a statement that he did not consider it propaganda when he told a newspaper in August that no Roman Catholic in good conscience would vote for the party. He says claims that he repeatedly proselytized against Mexico City's ruling Democratic Revolution Party, or PRD, are not true.
Valdemar was responding Sunday to Friday's decision by Mexico's highest electoral court ordering electoral officials to have the Interior Ministry fine Valdemar and the Archdiocese.
Valdemar's lawyer Armando Martinez says he is already in an appeals process.
Mexico City legalized same-sex marriage in March 2010.
