Is Chalabi in, or is Chalabi out?

Buried down at the bottom of this news article:

    Ibrahim Bahr al-Uloum, who resigned as oil minister last week over increases in consumer fuel prices, also resumed his old post after the prime minister and president asked him to do so, Iraq’s Council of Ministers said.

I am under the impression that Ahmad Chalabi had taken over as oil minister. Well, is he or isn’t he? No mention if Chalabi has stepped down.
