A subsidiary of Macquarie Group Ltd. is suing ATP Oil & Gas Corp., saying that it owns the rights to royalty payments from three ATP offshore-drilling operations, entitling it to payments and exempting those rights from ATP's bankruptcy estate, Dow Jones Newswires reported yesterday. Macquarie Investments LLC said prior to ATP's chapter 11 filing, it purchased for $110 million what ATP and several law firms assured it were "non-cost bearing overriding royalty interests that constituted real or immovable property rights" in the drilling operations, according to court documents. Its rights are to the oil, gas and other minerals produced at the three wells off the coast of Louisiana in the Gulf of Mexico, according to court documents.
