The federal judge who ordered a group of bankruptcy professionals to report conversations with Bloomberg LP reporters involving troubled rare-earths mining company Molycorp Inc. changed his mind yesterday and granted the news organization more time to mount a legal challenge, the Wall Street Journal reported today. Bankruptcy Judge Christopher Sontchi said that he may have erred in denying Bloomberg a chance to challenge the order he issued last week. That order required some 120 professionals involved in Molycorp’s chapter 11 case to file sworn statements about any conversation they had with Bloomberg reporters concerning the mining company in recent months.
