Void tax sale?

During the 1980s, the Jefferson Group failed to pay both a large loan and its property taxes.  The lender failed and the RTC/FDIC acquired the deed of trust for the loan, which it later assigned to another entity.  The local school district foreclosed on the property in 1990.  Many years later, a dispute arose between the entity who acquired the deed of trust, who asserted a lien on the (now-developed) land, and the owners who traced title to the foreclosure sale.  The district court dismissed on limitations grounds.  The Fifth Circuit concluded that if the RTC had not effectively consented to the foreclosure sale, then it violated 12 U.S.C. § 1825(b)(2), which meant that the sale “is, without qualification, ‘null and void.'”  This would mean that the current owners could not assert a limitations defense.  The Court remanded to consider whether a violation had occurred, in light of this conclusion about the effect of a violation.  CAP Holdings, Inc. v.
