Bouvier's Law Dictionary, Revised 6th Ed (1856):

RESALE. A second sale made of an article; as, for example, if A sell a horse
to B, and the latter not having paid, for him, refuse to take him away, when
by his contract he was bound to do so, and then A sells the horse to C.
     2. The effect of a resale, is not always to annul the first sale,
because, as in this case, B would be liable to A for the difference of the
price between the sale and resale. 4 Bing. 722; Blackb. on Sales, 336; 4 M.
