William O. Douglas,
Lewis v. Manufacturers National Bank of Detroit…
“ Security transactions entered into in good faith years before the bankruptcy could be upset if the trustee were ingenious enough to conjure up a hypothetical situation in which a hypothetical creditor might have had such a right. The rule pressed upon us would deprive a mortgagee of his rights in States like Michigan, if the mortgage had been executed months or even years previously and there had been a delay of a day or two in recording without any creditor having been injured during the period when the mortgage was unrecorded. ”
