( CNN ) -- Brazilian relatives of a 9-year-old boy , caught in an international custody battle with the child 's father , will not file any further appeals after the Brazilian Supreme Court ruled against them , their attorney told CNN Wednesday . The family is just looking for a peaceful handover of Sean Goldman to his father , attorney Sergio Tostes said , and plan on starting dialogue to allow the transfer to happen immediately . The chief justice of the Brazilian Supreme Court ruled Tuesday in favor of David Goldman , who had been battling the family of the boy 's deceased mother for custody . The ruling by Chief Justice Gilmar Mendes will reunite Sean with his father . Last week , a lower court unanimously upheld a decision ordering that Sean Goldman be returned to his father in New Jersey . David Goldman arrived in Rio de Janeiro to reunite with his son , but one Supreme Court justice issued a stay , ordering Sean to remain with his Brazilian relatives until the high court could consider the case . Mendes ' decision lifted the stay . This week the U.S. State Department issued a passport to Sean , given to his father , so that he can travel back to the United States , spokesman Philip J. Crowley said Wednesday . `` Our embassy in Brasilia , our consulate in Rio de Janeiro , many people have been up through the night just to provide support to the Goldman family , to maintain contact with the Brazilian government ... as we , hopefully , come to the end of this process and look forward to the reuniting of Sean Goldman with his father , David , '' Crowley said . The regional court decreed the boy must be handed over by 9 a.m. ( 6 a.m . ET ) on Thursday . `` Sean is very sad because it is not and has never been his desire [ to return to the United States ] , '' his grandmother , Silvana Bianchi , told CNN . `` He got especially disappointed about not having the right to speak in his own country [ about ] what he wanted for himself ... They are sending the boy to the United States without the right to defend himself . Where is the Brazilian constitution ? '' Bianchi was initially expected to appeal . But Tostes said Wednesday the family wants to act in the boy 's best interest , and he was meeting with an intermediary to arrange the handover . He said he would like Bianchi to meet with David Goldman so she can tell him what Sean likes to eat , what he enjoys doing and other details . Asked whether she would accompany Sean on the flight to the United States , Bianchi would only say Tostes is negotiating what is best for the boy . Upon hearing the family would file no further appeals , Rep. Chris Smith , R-New Jersey , said , `` This is not good news . This is great news . '' The custody battle began in 2004 , when Goldman 's wife , Bruna Bianchi , took their then-4-year-old son from their home in New Jersey to Rio de Janeiro for what was to have been a two-week vacation . She never returned , instead remarrying there and retaining custody of Sean . She died last year in childbirth . Goldman has argued that as the sole surviving parent , he should be granted custody . The Bianchi family maintained it would traumatize Sean to remove him from what has been his home for five years . The custody battle garnered much media attention and spilled over into the political arena as well . U.S. Sen. Frank Lautenberg , D-New Jersey , had placed a hold on a trade bill that would have benefited Brazil to the tune of $ 2.75 billion , but he lifted it after the court 's ruling , spokesman Caley Gray told CNN . The bill in question , which sailed through the Senate after the senator dropped the hold , provides export tariff relief to 130 countries , of which Brazil would be the fifth largest recipient , Gray said . Lautenberg 's hold was designed to exert additional pressure on Brazilian authorities to abide by the court order to return Sean to his father , he said . Silvana Bianchi told CNN Wednesday it was `` very sad , a country that exchanges children for economic agreements . '' While the chief justice was still studying the case , Brazilian Attorney General Luis Inacio Adams said the executive branch of Brazilian government sided with Goldman . `` Once we stop cooperating and start breaking our treaties and international obligations , Brazil risks the chance of not having its own requests in the matters regarding international judicial help granted , based on the principle of international reciprocity , '' Adams said Monday . `` Not releasing the minor into the custody of his father could bring sanctions against Brazil , '' he added . `` It could damage Brazil 's image before the international community . '' CNN 's Mariano Castillo and Adam Reiss and journalist Luciani Gomes contributed to this report .
