William Johnson, Minor v. The Mechanics Bank of Alexandria…
“ It is true, that, in general, the non-joinder of co-obligors must be pleaded in abatement; but it would be oppressive and inconsistent to apply this rule to a case, in which it was impossible to plead in abatement, and that was precisely this case; since the discharge of the principal from the action, was produced by the act of the plaintiff, after judgment, at a time when it was impossible, by any form of pleadings, for the defendants to avail themselves of this right. But this case comes within an exception to the general rule on the subject of pleas in abatement ”
