John McLean, Ronkendorff v. Taylor's Lessee…
“ The court recognize the correctness of the principle contended for by the counsel for the plaintiff in error; that in an ex parte proceeding of this kind, under a special authority, great strictness is required. To divest an individual of his property, against his consent, every substantial requisite of the law must be shown to have been complied with. No presumption can be raised in behalf of a collector who sells real estate for taxes, to cover any radical defect in his proceeding; and the proof of regularity in the procedure devolves upon the person who claims under the collector's sale. ”
