Buenos Aires , Argentina ( CNN ) -- Latin America 's first same-sex marriage , set to be held in Argentina on Tuesday , appeared derailed after a judge filed an injunction to stop the union until the issue can be reviewed further . Judge Marta Gomez Alsina 's ruling blocks an earlier holding by another judge that found city laws banning same-sex marriage unconstitutional , the court said in a statement . Alex Freyre and Jose Maria di Bello had planned to make their marriage official at a civil ceremony and chose December 1 because it is World AIDS Day . The registrar responsible for the civil marriages in Buenos Aires has been notified of the ruling , the court said . The couple would attempt to get their wedding license anyway , the official Telam news agency reported . `` We 're continuing with the preparations because we , as planners , nor the couple itself , have not been notified '' of the injunction , said Maria Rachid , president of the Argentine Federation for Lesbians , Gays , Bisexuals and Transsexuals , according to the news agency . Gomez Alsina 's injunction could not overturn the earlier ruling because she is a trial-level judge and not an appellate judge , Rachid said . The original ruling was made on November 10 by another trial-level judge , Gabriela Seijas , who responded to a petition made by Freyre and di Bello . Seijas ruled that the ban on same-sex marriage was illegal and ordered the proper authorities to grant the couple a marriage license if they applied for one . The court 's decision applied only to Buenos Aires . Same-sex unions in most of Argentina remain illegal . `` The law should treat each person with equal respect in relation to each person 's singularities without the need to understand or regulate them , '' Seijas said in her ruling . Buenos Aires Mayor Mauricio Macri said after the ruling that his government would not appeal the decision . Monday 's ruling was a temporary measure to postpone the marriage until Seijas ' original ruling could be reviewed in depth , presumably by an appeals court or the supreme court , the court statement said . Countries in Latin America , a region strongly identified with the Catholic Church , have recently given more attention to gay rights . In September Uruguay became the first Latin American country to allow same-sex adoption . Brazil , Colombia and Ecuador are also addressing the issue of same-sex civil unions .
Freyre and Di Bello 's marriage was to coincide with World AIDS Day on Tuesday . They would attempt to get their wedding license anyway , Telam reported . Original ruling was that a ban on same-sex marriage was illegal . Court : Injunction is temporary measure to postpone marriage pending review of original ruling .
