Update: Judge blocks ‘House of Cards’ plan by Brazil’s ex-president to gain immunity

The somewhat crazy world of Brazilian politics took a new twist: Former President Luiz Inacio "Lula" da Silva had planned to take over as chief of staff in his successor’s cabinet, a move that partly insulates him from criminal investigations.

That is, until massive protests and a block by a judge of the scheme.

Da Silva, commonly known as Lula, has become embroiled in a sprawling investigation into corruption at the state oil company, Petrobras. The investigation, which has brought down several of Brazil’s most wealthy and powerful people, took a sensational turn this month when Lula was detained for questioning and his property was searched.

In office from 2003 to 2011, the once wildly popular president is revered for overseeing fantastic economic growth, while also bringing tens of millions of people out of poverty. But now Lula is scrambling to protect his legacy and stay out of jail.

Critics think the top cabinet job plans looks like a desperate attempt to take advantage of Brazil’s laws on parliamentary immunity.

The entire Brazilian Congress — almost 600 people — enjoys immunity from prosecution in ordinary courts.

Instead, members of Congress must be investigated and tried in the Supreme Court, a process that can drag on for years. The court is currently overloaded with prosecution cases (scores of Brazilian politicians are being criminally investigated), and politician-friendly laws result in some bizarre situations in the legislature.

In 2013, The New York Times reported that about a third of Brazilian members of Congress faced Supreme Court charges, ranging from “siphoning off public funds to far more serious claims of employing slave labor on a cattle estate or ordering the kidnapping of three Roman Catholic priests.” It said lawmakers in corruption cases often dodge prison.

The accusations against Lula are pretty mild by the standards of the Petrobras scandal. He is being investigated for allegedly accepting hundreds of thousands of dollars worth of furniture and improvements to properties that prosecutors say he owns. By contrast, other politicians are accused of taking tens of millions of dollars in bribes.

The former president denies any wrongdoing.

Complicating matters, Lula is being investigated by both federal and state prosecutors. The federal prosecutors have yet to charge him with a crime, but last Thursday state prosecutors in Sao Paulo charged him with money laundering in connection to his real estate holdings.

If he manages to get past the judge's ruling and join Brazil’s cabinet, Lula would effectively be able to brush off the state charges, which he has claimed are politically motivated. The federal case could still proceed against him via the Supreme Court route.

Lula and his supporters have portrayed his sudden drive for a cabinet post as a way of giving support to current President Dilma Rousseff. Rousseff is herself facing impeachment, over yet another investigation, and analysts have recently begun saying she’s unlikely to survive her second term in office.

To top it off, a senator now accuses President Rousseff of involvement in that same huge Petrobras scandal, too. 

Lula hoped to serve in the same government post — chief of staff — that he hired Rousseff for in his administration. 

It’s an odd power dynamic: Deeply unpopular Rousseff has traditionally drawn much of her popularity from Lula, who effectively handpicked her as his successor. Lula’s recent disgrace and possible conviction could erode much of that support.

But the former president now needs Rousseff as much as she once needed him. As he joins Brazil’s cabinet, he will at least have some breathing room as prosecutors rebuild and renew their case against him.

At least one American TV show liked the chaos, one that specializes in such maneuvers.
