The crusading judge behind the Petrobras investigation, Sergio Mora, accepted charges filed last week by prosecutors investigating Lula -- making him the highest-profile figure to face trial in a case that has taken down some of the country's most powerful business executives and politicians.
"Given that there is sufficient evidence of (Lula's) responsibility... I accept the charges," Moro said in his decision.
The charges allege that Lula, 70, received the equivalent of 3.7 million reais (USD 1.1 million) in bribes.
More broadly, prosecutors last week singled out Lula -- who was president during much of the time that Petrobras was being fleeced of billions of dollars -- as the scheme's "supreme commander."

Lula, who presided over an economic boom from 2003 to 2011, will now go head to head for the first time with Moro.
The crusading judge's anti-graft investigation, known as Operation Car Wash, has had explosive consequences in Brazil.
It already played a part in ousting the leftist Workers' Party, which he co-founded.
The once unstoppable party's 13 years in power ended last month when Lula's hand-picked successor, Dilma Rousseff, was convicted of budget irregularities in an impeachment trial.
The charges against Rousseff were unconnected to the Petrobras case, but the scandal -- combined with Brazil's worst recession in decades -- did much to bring her down.
Rousseff was replaced on August 31 by center-right President Michel Temer, her vice president-turned-nemesis.
He has vowed to slash a ballooning budget deficit and lead Latin America's largest economy back to growth.
Lula was hailed internationally for combining business-friendly economic policy with social-welfare programs that helped fight centuries of deep-rooted inequality in Brazil.
He also was key in winning hosting rights to the 2014 World Cup and the Rio de Janeiro Olympics, which finished on August 21 -- South America's first.
