But what Kornreich gave the bond insurers with one hand, she took away with the other. In the same 2011 decisions, the judge ruled that Ambac and MBIA had waived their rights to a jury trial in the contracts they signed with Credit Suisse. That meant that she, rather than a jury, would decide the merits of those newly reinstated fraud allegations - and she didn't think there was much merit to them. Kornreich's decisions said that Ambac and MBIA couldn't just point to the MBS offering materials and claim they were duped. Credit Suisse, she said, had offered ample notice of potential weaknesses in the underlying loan pool. To prove fraudulent inducement, she ruled, Ambac and MBIA would have to show that the bank engaged in outright deception.
