Brazil's popular leftist former leader Luiz Inacio Lula da Silva, due to begin precandidacy for the presidency on May 27, is the subject of a new United Nations investigation into whether his judicial rights have been violated.
On Tuesday, the United Nations Committee for Human Rights (UNHCR) said it was initiating a formal investigation into violations against basic judicial guarantees in Lula's case.
However, the same organization also rejected a petition by Lula's lawyers for an injunction to avoid prison, saying that first "it must be demonstrated that the state is irreparably violating the rights of the person, and based on the information that Lula has given the committee, he is not demonstrating a risk of suffering irreparable harm of that sort."
Despite denying the initial request, the investigation will now be carried out to determine if his rights were violated.
Lula is able to submit another petition for an injunction if he feels "there are new elements that demonstrate he will suffer irreparable damage," the committee said.
The UNHCR also issued a warning to Brazil's government authorities that any act "that impedes or frustrates the analysis of the committee" is a violation of the International Pact of Civil and Political Rights.
The Workers' Party of Brazil, which Lula founded, intends to announce Lula as the leader and representative of the political group, despite his imprisonment for alleged corruption that many say is a form of 'lawfare' designed to prevent his candidacy.
Lula has consistently proven the most popular politician and presidential candidate in the country, and polls place him in a far lead for the elections. Brazil's election outcome very likely depends on whether the former president is permitted to run.
To much outcry from supporters among the popular classes, Brazil's most popular politician was detained in April after a federal court declined to uphold his habeas corpus petition.
