William R. Day,
Great Northern Railway Company v…
“ But the position of a bona fide purchaser is not to be assumed from the allegations of the complaint, which do no more than state the several transfers, without any allegation showing affirmatively that the defendants are bona fide purchasers for value, in which event only could this defense be successfully made by demurrer to the complaint. Bona fide purchase is an affirmative defense, which the grantee must set up in order to defeat the right of the railroad company to have a trust declared in the lands in question, if the bill is otherwise sufficient for that purpose. ”
