Quando Res Non Valet Ut Ago, Valeat Quantum Valere Potest Law and Legal Definition

Quando res non valet ut ago, valeat quantum valere potest means when the thing is not valid as I do it let it have as much validity as it can have. It signifies that wherever a party has the power to do a thing (statute provisions being out of the way), and means to do it, the instrument he employs should be so construed as to give effect to his intention. [Bond v. Bunting, 78 Pa. 210, 219 (Pa. 1875)].
