Issuable plea

A plea to the merits; a traversable plea. A plea such that the adverse party can join issue upon it and go to tnal. It is true a plea in abatement is a plea, and, if it be properly pleaded, issues may be found on it. In the ordinary meaning of the word "plea," and of the word "issuable," such pleas may be called "issuable pleas," but, when these two words are used together, "issuable plea," or "issuable defense," they have a technical meaning, to-wit, pleas to the merits.
