InIn re: Delta Petroleum Corp. (Bankr. Del. Apr. 2, 2015), the bankruptcy court (the “Court”) considered competing motions for summary judgment as to whether certain overriding royalty interests (“ORRIs”) constituted (1) mere contractual rights to payment that were discharged by the confirmed chapter 11 reorganization plan or (2) real property interests that were not part of the estate in bankruptcy and, thus, survived the trustee’s challenge.
