BRASÍLIA: Brazil’s Supreme Court on Wednesday postponed a decision on whether to authorize the controversial appointment of former leader Luiz Inacio Lula da Silva to the embattled government of his protégée, President Dilma Rousseff. The latest delay leaves Lula, who was named chief of staff last month, in limbo while Rousseff’s own job hangs by a thread amid an impeachment fight that could see her forced to step aside within weeks. “By a majority, the court decided to postpone the ruling” in order to examine all the files in the case in a single session, chief justice Ricardo Lewandowski said, without setting a date for a new session. Rousseff had given Lula—her influential predecessor and mentor — the ministerial job on March 16, betting on his political prowess to save her from impeachment. But a Supreme Court judge temporarily blocked the appointment, citing suspicions that it was a bid to shield Lula from prosecution in lower level courts in connection with a massive corruption case at state oil giant Petrobras.
